Patent GB-2044620-A (GB)
Title: Administering parenteral fluid
IPC: A61M5/165
Filed: 1980-03-17
Abstract: Parenteral fluid administration apparatus 10 parenteral reservoir chamber 20 enclosed at one end by a piercing pin assembly 22 for attachment to a parenteral solution bag (not shown) and at the other end by a drip forming member 26. Extending into chamber 20 and in fluid communication with member 26 is a fluid passage means 30 in the form of a tubular member 32 having an orifice 33 covered, e.g. with a filter membrane 31. As the fluid level drops in chamber 20, liquid contacts less area of membrane 31 thus affording a slower fluid flow rate until a new solution bag can be provided. <IMAGE>

Title: Stretch-blow moulding a two layer article
IPC: B29C49/06
Filed: 1980-08-28
Abstract: A method for producing a hollow product, such as a bottle 4, by injection stretching and blow moulding involves injection moulding a two-layer parison 3 with a closed bottom, one layer 1 consisting of a readily stretchable, blow mouldable resin (e.g. polypropylene) and the other layer 2 consisting of a resin which is hard to stretch and blow mould (e.g. acrylic resin). The parison is adjusted to an appropriate temperature before stretching the two layers of the parison and at the same time blowing air into the parison, while the latter is mounted in a blow mould, to form the article by blow moulding. The method avoids the difficulty of rupture, and undue thickness variation in the layer of resin which is hard to stretch and blow mould. <IMAGE>

Patent GB-2076505-A (GB)
Title: Valve
IPC: F15B11/16
Filed: 1981-02-12
Abstract: The valve serves to coordinate two fluid-actuated mechanisms, such as a pneumatically-actuated spring brake system and a pneumatically- actuated service brake system in a motor vehicle. Port 44 is connected to the pressure line of the spring brake system, and so long as pressure prevails therein to maintain the spring brake system inoperative, a diaphragm 82 is deflected to displace push rod 74 to lift ball valve member 58 off its seat 60. Valve member 58, when open, permits exhaust air from the service brake system to escape to atmosphere, through opening 64, when the latter system is inoperative. Accordingly when the pressure at port 44 falls upon the spring brake system becoming operative, valve member 58 closes to prevent escape of the exhaust air, thereby maintaining the service brake system operative and ensuring combination of the two braking systems. The seat member 54 is movable away from the ball 58 against the action of springs 62 to relieve excess pressure in the service brake system when the rod 74 is in the retracted position. <IMAGE>
Patent GB-2072308-A (GB)
Title: A hydrostatic drive having an open hydraulic circuit
IPC: F16H61/40
Filed: 1981-02-25
Abstract: The hydraulic drive comprises a hydraulic pump 4 and a hydraulic motor 1, between which is arranged a 4-3 way valve 2 for controlling the stream of pressure fluid from the pump 4 selectively to flow to and return from the hydraulic motor 1 and for directing the pressure fluid to a reservoir 5 when the motor 1 is idling or stationary. A control valve 3 is arranged between a feed line 41 to the hydraulic motor 1 and a return line 31% therefrom for selectively connecting together or separating such feed line and return line. The control valve 3 has a first variable throttle means 3% between the feed line 41 and the return line 31% and a second variable throttle means 3_ between the first throttle means 3% and the reservoirs. The two throttle means 3' and 3_ are operatively connected together for simultaneous actuation by a common adjusting device 3>. Such arrangement prevents interruption of the flow of pressure fluid to the motor 1, and therefore damage to the motor, when the latter acts as a pump during downhill travel. <IMAGE>

Title: Piecing yarn to broken end of thread in a spinning machine
IPC: D01H15/00
Filed: 1981-03-20
Abstract: A broken end of yarn E and an end of thread D are caused to move simultaneously opposite to one another and, after the ends of yarn and thread are brought close together, they are caused to deviate from the path of their initial movement and to run at a distance from one another in such a manner that during the untwisting of the end of yarn it engages the end of thread to form a knot. The piecing is carried out by a device for gripping and transferring the end of yarn to a pulling device, which is formed by a pipe having an outlet pipe connected to a source of reduced air pressure. <IMAGE>

Title: Graphite-fluoride coated with organic polymer and method of preparing same
Inventor: TSUKUDA HITOSHI
IPC: C10M123/02
Filed: 1982-10-19
Abstract: Graphite fluoride, such as (CF)n or (C2F)n, in powder form coated with a vinylic polymer, e.g. polymethyl methacrylate, which is bonding to the surfaces of the graphite fluoride particles by graft polymerization. The polymer-coated graphite fluoride retains unique properties of graphite fluoride such as high lubricating ability, can readily be dispersed in water and organic liquids, and can readily be press-shaped with or without the addition of a synthetic resin powder. The polymer-coated graphite fluoride is prepared by mixing graphite fluoride in powder form with at least one vinylic monomer which undergoes radical polymerization in the presence of water, for example by dispersing these materials in a mixture of water and ethanol, and then adding a polymerization initiator to the resultant mixture. The polymerization reaction takes place even at room temperature and can be promoted by heating up to 70 DEG C. Preferably the pH of the polymerization reaction system is adjusted to 5-9 by adding alkali or by treating graphite fluoride with alkali in advance.

Filed: 1983-08-15
Abstract: An electromyogram has a pair of electrodes 12, 14 which are secured to the skin surface over a muscle to be investigated, to measure the small voltages produced at the skin surface by muscle activity. Because there is no invasion of the body, the instrument is quick and easy to use.

Electrodes 12 and 14 are connected to transistors T1 and T2 arranged as a differential pair feeding a differential amplifier A2. After further processing by lum filters based on transistors T5 and T6, a variable gain amplifier IC2, and a bandgrass filter based on amplifier A3, the measurement signal may be displayed on an oscilloscope or recorded. The portion of the signal above a threshold level is applied to a meter M1 and to an oscillator IC4 which feeds pulses to a loudspeaker LS1 at a rate proportioned to the measured signal. <IMAGE>
