Patent GB-1473085-A (GB)
IPC: F25B1/00
Filed: 1973-06-20
Abstract: 1473085 Refrigerating HOWDEN COMPRESSORS Ltd 10 June 1974 [20 June 1973] 29264/73 Heading F4H In a compression-condensation refrigeration system in which an oil separator 8 is connected to the outlet 12 of the compressor 1, oil from the separator is cooled before it is readmitted to the compressor in a cooler 9 which is supplied with a portion of the condensate refrigerant exhausted from the condenser 2. As shown, the condensate portion passes through a line 7a and a valve 14, which is controllable in accordance with the temperature of the oil leaving the cooler 9, to the cooler. In cooling the oil, the condensate refrigerant is vaporized and is supplied directly to the compressor through an additional inlet 13 which communicates with a compression space or land in a rotor of the compressor when the space or land is cut-off from the compressor inlet 11. In a modification, Fig. 3 (not shown), a vessel is provided between the condenser and an expansion valve 3 and separates vaporized from liquid refrigerant. The vaporized refrigerant is supplied along a gas line which joins a liquid refrigerant line between the cooler 9 and the compressor. In a further modification, Fig. 7 (not shown), the vaporized refrigerant from the vessel 6 is supplied directly to the compressor. Alternatively, the cooler may be supplied with liquid refrigerant from the vessel 6, Figs. 5, 9 (not shown). The separate oil cooler vessel 9 may be omitted, the oil being passed through a coil in the vessel 6, Fig. 11 (not shown).

Title: Improvements in or relating to navigation aiding radio receiving systems
IPC: G01S1/02
Filed: 1938-10-10
Abstract: 503,471. Directive wireless systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 10, 1938, No. 29326. Convention date, Oct. 8, 1937. [Class 40 (v)] A direction-finding receiver, e.g. a "homing" receiver, in which the phase of an input signal to the receiver is periodically reversed, is provided with an oscillograph indicator to which dephased deflection voltages are applied causing the indicator spot to describe a closed path at the frequency of the phase reversal, the receiver output being fed to the oscillograph so as to cause the spot to depart from its normal path to an extent depending upon any amplitude change occurring on phase reversal. In the honiing receiver shown in Fig. 6, the pick-ups from the frame and open aerials, a and b, are fed in parallel and in push-pull respectively to the two amplifying valves V1, V2 which receive anode voltages from the local oscillator G, the voltage of which is such that the two valves are rendered alternately conductive thus periodically reversing the phase of the open aerial pick-up. The amplifier output is fed through the transformer T, rectified, and passed through the resistance W, the voltage across which is applied to the accelerating anode A of the cathode-ray tube f to control its deflection sensitivity. Deflection voltages in phase quadrature are derived from the generator G and applied to the deflection plates P1, P2 causing the cathode-ray beam to describe a circle, the frequency of rotation of the beam being equal to the phase-reversal frequency. When thevehicle is "on-course" the amplitude of the combined pick-ups is constant for both positions of the phase-reversal means and the resultant oscillograph trace is a circle, but for "off course positions the amplitude differs for the two positions giving two semicircles of different diameter Fig. 5. Alternatively the distorted trace could be produced by causing the amplifier output to modulate the deflecting voltages and the 'amplifying valves could be replaced by diodes or other rectifiers.

Title: Improvements in apparatus for the control of respiration, resuscitation and anaesthesia
IPC: A61M16/00
Filed: 1948-11-11
Abstract: 649,229. Anaesthetic apparatus. BLEASE, J. H. Nov. 11, 1948, No. 29375. [Class 81(ii)] Apparatus for controlling respiration and anaesthesia comprises a pressure-responsive device controlling the cyclic rise and fall of pressure in an air chamber, and a second chamber, communicating with the first and containing a collapsable bag the interior of which is connected with the patient's lungs. In the apparatus described a chamber 15 is supplied with air through an inlet 14 and, as the pressure rises, at a rate determined by a leak valve 47, a diaphragm 18 is thrust outwards, against a spring 42, thereby tensioning a spring 29 and tending to turn a disc 25 which does not, however, rotate until a detent pawl 32 is withdrawn, at the end of the diaphragm's movement, by a pin 38 on a bracket 37. When so released the disc swings over and opens a valve 20 to release the pressure to atmosphere. The diaphragm now returns towards the left, its rate of movement being determined by the leak through a needle valve 41, and at the limit of this second movement, the disc is released for counterclockwise rotation by a tripping of pivoted pawl 33, and the valve 20 is closed so that the cycle is repeated. The interior of the chamber 15 communicates with a second chamber 4 containing a flexible breathing bag 46, the interior of which communicates with a face mask through a tube 2. As the pressure inside the chambers rises and falls the bag 46 is made to collapse and expand, thereby pumping its contents to and from the patient. Provision for manual control of the rate of respiration is made by closing a valve 52, to render valve 20 ineffective, and actuating a manual release valve, see Fig. 3 (not shown). Anaesthetic or other gas is introduced into the system through a branch pipe controlled by a cock 10 and the excess gas of each expiration escapes through a release valve 65. The apparatus is also fitted with a valve 55, which allows the patient to inspire directly from the atmosphere if the apparatus should fail to function, and also two screw valves 70, 72, of which the first controls the admission of air to the mask from a pipe. not shown, connected to the air pump, while the latter provides a direct communcation to the atmosphere.

Abstract: 1306121 Pulse radar THOMSON-CSF 17 June 1970 [19 June 1969] 29488/70 Heading H4D A method of improving response of a staggered p.r.f. radar includes the steps of forming differences between successive echoes from the same target and forming a weighted sum thereof, wherein the weighting coefficients are selected to give the differences the same values of as if the p.r.f. were constant. Using coherent detection quadrature channels are produced and treated identically. The phase detector outputs are sampled twice per pulse, coded and fed into three-stage memories N1, N2. Amplifiers A2, A3 and A4, A5 form the differences from three successive echoes. These are passed to multipliers MP1, MP2 and MP3, MP4 which each comprise a d-a converter, variable gain amplifier, and an a-d converter. The multiplier outputs are added and pass to filtering circuits FD before passing to the utilization circuits. The amplifier gain in the multipliers is set by the synchronizing unit SY which provides the necessary information on the p.r.p. The multiplying factors are given by k = number of recurrences per stagger cycle, T i  = ith recurrence period, t mi  = difference between the times elapsed since the first pulse of the cycle up to the centre of the (i - 1)th recurrence and up to the centre of the (i - 1)th mean recurrence In the case where the p.r.p. remains constant over one revolution of the radar antenna and then changes correction is only required for p pulses about the azimuth angle at which the change takes place. The method reduces the effects of spreading the fixed echo spectrum due to changing the p.r.p.

Abstract: 351,355. Pickling meat,. FISCHER, M. N E G E L E -, 8, Wiedenmayerstrasse, Munich, Germany. Oct. 2, 1930, No. 29536. [Class 49.] Meat in large pieces is rapidly pickled by inserting hollow perforated needles c into the meat b which is placed in a container a, the container being then sealed airtight and the air exhausted therefrom and, through the nozzles e, from the interior of the meat, pickle being finally forced into the meat through the nozzles. In the method described, the nozzles e are connected by tubes d to a common distributer e from which a tube f leads to near the bottom of an empty vessel g connected by a pipe m with the lower part of container a, and which can be connected through a valve i with the outer air. The air is first removed through an outlet h from the container a and also from the interior of the meat through the nozzles e which are in connection with the container a through the vessel g. A cock k connected to tube f and a cock in tube m are then closed and vessel g is filled with brine and cock k again opened, the brine being thereupon forced through nozzles e into the meat under atmospheric or, if desired, higher pressure and drawn by the vacuum in the container a through the meat. Vacuum and pressure may be made to operate separately instead of simultaneously. The pickle may be made to pass directly into container a through tube m.

Abstract: 376,593. Cable splicing machines. QUANTE, W., 353, Uellendahlerstrasse, Elberfeld, Wuppertal, Germany. Oct. 27, 1931, No. 29809. Convention date, Oct. 27, 1930. [Class 38 (i).] Comprises a cable jointing machine in which the operations of cutting, stripping, twisting, &c. are performed by moving handles which are arranged in suitable positions for convenient handling. A machine for jointing four-cored cables is illustrated. The four pairs of ends are passed through the jaws of grippers 6, Fig. 1, and slots in cutting blades 32, 33. Movement of the handle 2 cuts the ends to length, the slots in blades being arranged so that the pairs of ends are cut successively. Pressure on a lever 1, Fig. 2, closes the gripper jaws by means of a plate 8 which engages with annular recesses in the grippers. The grippers are carried by a framing 10, Fig. 4, mounted on slides, pressure on a lever 3 causes horizontal movement of the frame to effect stripping of insulation from the wires by means of the grippers. Rotation of a handle 4 will, through suitable gearing, rotate the grippers to twist together the pairs of conductors. The twisted ends are cut to length by means of knives 22, 23, Fig. 5, operated by a lever 5. A shaft 16 geared to the lever 5 has two cranks 17, 18. When the arm 5 is pressed, crank 17, by means of levers 20, moves the knife vertically into operating position against stops 27, 28, additional movement being absorbed by a spring coupling 21.
