Patent GB-1258071-A (GB)
IPC: A61M16/10
Filed: 1968-03-04
Abstract: 1,258,071. Anaesthetic systems. R. HESSE. 4 March, 1969 [4 March, 1968], No. 10419/68. Heading A5T. [Also in Division F2] A rebreathing anaesthetic system includes a valve arrangement having a gas release or blow off valve 8 which opens when a first (low) pressure in its vicinity in the system is exceeded and is closed by an arrangement including a pressure detector 9 when the pressure in the vicinity of the detector exceeds a second and higher pressure. The arrangement is to permit gases to be vented from the system during normal breathing, and if forced ventilation of the patient is necessary, extra pressure can be applied to the system and the gas release valve will be closed temporarily.  Preferably the valve arrangement includes a housing 15 with inlet, outlet and bladder connections 16, 17, 18 and the pressure detector 9 closes the blow off valve element by means of a double armed lever 13. A one way valve 28 between the bladder connection and pressure detector and the blow off valve compels the pressure pulse originating in the squeezed bladder to pass to the patient before reaching the blow off valve. The pressure at which the detector 9 causes the blow off valve to close may be varied, e.g. by means of a movable magnet 21 and an iron armature 22 carried by the lever. In alternative arrangements the bellows 9 is replaced by a piston (10 Fig. 3 not shown) in a cylinder (11); the higher pressure at which the blow off valve is closed may be altered by means of a sliding weight (31 Fig. 4 not shown); the lever may be replaced by telescopic (34 Fig. 5 not shown) or flexible (33 Fig. 6 not shown) connectors linking the detector and blow off valve element 14; by means of a curved conduit (36 Fig. 7 not shown) from valve housing 15, bellows 9 itself may act on the valve element 14, to close it at the higher pressure. In an emergency, button 37 may be pressed to hold the blow off valve open to release gas.

Abstract: 117,665. Liebowitz, B. July 23, 1917. Vibration-dampers ; connexions.-A spring suspension for motor and other vehicles comprises initially strained springs to which the oscillations of the body are transmitted in a reduced ratio varying inversely as the load, so that the variation of strain in the spring during working is small compared to the initial strain. Fig. 1 shows a suspension in which two initially compressed springs contained within casings 9, 10 are arranged between the axle and undercarriage so that the springs would be horizontal and still compressed if the device were under no load. Simple tension springs may be used instead of compression springs in casings. Fig. 4 shows a modification for use with axles connected to the frame by radius rods represented by the line R. The axle is connected by links 15, 16 to members 13, 14 which slide on alined rods 11, 12 carried by brackets on the chains. Initially-compressed springs 17, 18 are arranged between the members 13,. 14 and a yoke 19 capable of sliding on the rods 11, 12. This arrangement permits adjustment of the rod R. By fixing the yoke 19 the device may be used with a front axle. The links 15 are duplex to give lateral rigidity. All these forms have a vibration damper 20 which may consist of two disks 42. Fig. 7, formed respectively with arms 43, 44, the arm 44 being connected to the axle 3 by the lostmotion connexion shown.

Filed: 1973-03-06
Abstract: 1421272 Automatic control of thread-cutting OKUMA MACHINERY WORKS Ltd 6 March 1973 10726/73 Heading G3N A thread-cutting system in a numerical control unit for a machine tool employs a function generator employing two cascaded accumulators the output of which is applied to an arithmetic unit controlling the machine tool to produce a screw thread of progressively varying pitch. As shown, command signals F, L representative of the pitch and length of a threaded portion to be cut on a workpiece 12 are entered into a register 2 from a tape reader 1. The contents of the register and pulses N from a generator 11 coupled to a shaft 13 of a lathe are applied to a function generator 3 to produce varying command signals P which are compared with pulses B 1  from a generator 10 representative of the position of a toolpost 9. The comparision is effected in an arithmetic unit 4 and through a digital-to-analog converter 5 applied to a control unit 6 for a servomotor 7 driving the lead screw 8. The function generator 3 comprises a shift register receiving a signal representative of pitch variation per shaft revolution H and producing an incremental value # which is gated to an arithmetic unit. The contents of the arithmetic represents the present pitch and is held in a further shift register from which it is fed back to the arithmetic unit. The second shift register initially receives the pitch command from the tape and outputs a signal #x representative of the axial movement of the  tool post 9 per main shaft pulse. The signal #x is fed through a gate to a second arithmetic unit in a closed loop with a third shaft register, initially fed from the generator 10 the contents of which represent tool position P and form an input to the arithmetic unit 4.

Abstract: <PICT:0813016/IV (a)/1> <PICT:0813016/IV (a)/2> <PICT:0813016/IV (a)/3> In apparatus for melt-spinning wherein the molten polymer is pumped through a filter pack containing a filtration medium, a melt distributer plate and a spinneret, the holes of which lie in an annular trough, the top surface of the distributer plate has a number of radial channels, each of which is connected by a duct or ducts to an annular channel on the underside of the distributer plate, said annular channel being located above the annular trough of the spinneret and being at least as wide as the upper width of the annular trough, and said duct or ducts entering the channel at or near the edges thereof.  As shown in Fig. 1, the pack body 1 supports the outer rim of an annular spinneret 2, the inner rim of which is supported by the lock nut 3 which screws into the distributer plate 4.  Stainless steel mesh screens 6 contain the sand filter 7.  Radial channels 8 (Figs. 1 and 2) are cut in the top face of plate 4 and are connected by the ducts 9, 10 to the annular channel 11 machined in the bottom face of plate 4.  In use, the molten polymer flows through the sand 7 and gauzes 6 into the channels 8 and along these channels to the ducts 9, 10, through which it flows into an annular trough 12 in the spinneret 2 and thence through spinneret holes in the trough. In the preferred embodiment of the invention shown in Fig. 4, the molten polymer flows along the radial channels 8 to the outer edge of the spinneret trough 12 through an annular recess 14 between the distributer plate 4 and the pack body 1.  The recess 14 is connected to the radial channels 8 by the ducts 15 and to the spinneret trough 12 by the ducts 16.  The above arrangements prevent the formation of zones of stagnant degraded polymer in the recess made where the distributer plate touches the spinneret on either side of the trough and in the annular space between the distributer plate and the pack body.  Entry of degraded polymer at intervals into the main stream of melt is thus prevented.
