Cap device for mixing different kinds of materials separately contained therein and in bottle

A cap device for bottles, which is capable of mixing two different additives separately contained therein with a material contained in a bottle to prepare a mixture in accordance with a simple rotating action of the cap device relative to the bottle, performed by a user, thus allowing the user to easily prepare the mixture just before drinking or using the mixture. The cap device has a cap cover acting as an additive containing part, and defining a cavity therein, with a partition wall provided in the cavity to divide the cavity into two chambers and to separately contain two different additives in the chambers; a first funnel part provided at a lower section of the cap cover; a breakable sheet having a structure to be easily broken by external impact provided at an open lower end of the first funnel part to close the open lower end of the first funnel part; a cap body assembled with a lower end of the cap cover externally tightened to an externally threaded mouth of a bottle; a second funnel part having the same shape as the first funnel part provided at an upper section of the cap body, such that the first and second funnel parts are spaced apart from each other or come into contact with each other; and a means for breaking the breakable sheet so as to open the lower end of the first funnel part.

Spinal Rod Guide For A Vertebral Screw Spinal Rod Connector Assembly

A spinal rod guide and/or guide assembly is provided for mounting a spinal rod onto a spinal rod holder/connector of a vertebral bone screw. The spinal rod guide is configured to extend between an opening in a patient's body and the spinal rod holder of the vertebral bone screw assembly, to receive a spinal rod therein, and thereafter accurately guide the spinal rod into the spinal rod holder. The spinal rod guide is defined by a first elongated arc portion and a second elongated arc portion to define a guide tube for the introduction and placement of additional spinal rod components onto the spinal rod connector, particularly, but not necessarily, for securing the spinal rod into the spinal rod connector. The elongated arc portions are mountable or initially attached onto a top of a spinal rod holder of a spinal rod bone screw assembly. The elongated arc portions (tube) define first and second longitudinal slots extending from a top of the elongated arc portions to a bottom of the elongated arc portions. The two longitudinal slots are situated such as to be diametrically opposite one another. Each longitudinal slot aligns with a spinal rod slot of the spinal rod holder to thereby allow easy placement of the spinal rod into the spinal rod holder. Thereafter, the defined elongated tube provides direct communication and alignment with the top of the spinal rod holder in order to receive a spinal rod connector drive screw for securing the spinal rod into the spinal rod holder.

Method of forming fractures by means of hydrofracturing assisted by alternate spraying of high- and low-temperature fluids in deep hot dry rock

ActiveCN108979609AImprove the problem of difficult hydraulic fracturingIncrease the number ofFluid removalFracturing fluidMicro fracture
The invention provides a method of forming fractures by means of hydrofracturing assisted by alternate spraying of high- and low-temperature fluids in deep hot dry rock. The method herein includes: setting out a well network, and performing primary hydrofracturing to form main fractures; injecting a high-temperature high-pressure fluid and low-temperature water alternately into the main fractureswithin short alternate time; forming micro fractures in the rock at the surface of the main fractures under the thermodynamic action of a great temperature difference and the impact action of a jet; allowing multilevel fracturing to enable the micro fractures to further expand and form more micro fractures under the action of a low-temperature waterborne fracturing fluid and the action of high pressure; repeating until the main fractures and the micro fractures are in mutual lap joint and communication so that a fracture cluster and/or a fracture belt is formed between injection wells and production wells; injecting a sand-carrying fluid, a proppant and a displacing fluid, and closing the wells to complete fracture forming so as to construct an efficient heat exchange reservoir. The methodenables the quantity of the fractures to be significantly increased via the thermal stress action of the temperature difference, so that a fracture network is formed; heat exchange efficiency of a heat storage space is improved.
