Title: Arrangement for supplying sealing fluid to a fluid seal, more particularly on high pressure machines
Inventor: REAL PAUL
IPC: F16J15/40
Filed: 1967-12-21
Abstract: 1,145,668. Liquid seals. BROWN BOVERI & CO. Ltd. 21 Dec., 1967 [23 Dec., 1966], No. 58042/67. Heading F2B. A system for supplying sealing fluid, e.g. oil, to a shaft seal 5 of a machine, e.g. a compressor 1, comprises a main pump 11 for supplying sealing fluid to the seal during normal operation of the pump and an emergency pump 21 for supplying sealing fluid to the seal if the main pump 11 fails, the pump 21 being continuously driven by the machine when in use but in an unloaded condition during normal operation of the pump 11, and means for automatically rendering the pump 21 operative to supply sealing fluid when the pump 11 fails. Both pumps draw oil from a container 7. The pump 11 is driven by an electric motor 13 and during normal operation supplies oil through a non-return valve 15 and a pipe 17 to the oil seals 5 around the compressor shaft A at a pressure exceeding the gas pressure in a chamber 14 and controlled thereby via a valve 12. The emergency pump 21 is driven by the compressor shaft A and normally runs light, the pumped oil being returned to the container 7 through pipes 23 and 28, a second gas-pressure controlled valve 25 which is open during normal operation of the pump 11, and a pipe 30. If the pressure in pipe 17 falls due to failure of pump 11, the valve 25 closes and the pump 21 supplies pressure oil to the seals 5 via the pipe 17 and a non-return valve 24. The emergency closing operation of the normally open valve 25 may be tested by opening a test valve 27 to reduce the pressure in branch pipe 26, thus simulating a fall of oil pressure in pipe 17.

Abstract: 1,207,758. Electromagnetic switches, vacuume switches, electrodynamic actuators. ALLISCHALMERS MFG. CO. 13 Dec., 1968 [20 Dec., 1967], No. 59459/68. Headings H1N and H1P. An actuator for a vacuume switch 12 having a bridging contact 22 moved by a shaft 30, has alternately energized coils 50, 52 which repel respective conducting members 92, 86 to drive the shaft between stable positions. The shaft 30 is biased to the position shown by springs 74, 76 and is moved to its other position when the member 92 is repelled on pulse energization of the coil 50 so that a spring 96 is compressed to urge the member 86 down and stress a spring 88 acting on a collar 82 on the shaft 30 to bring an armature 68 on the member 86 into the field of a permanent magnet 58 acting through magnetic pole members 56, 60 to retain the member 86 and shaft 30 in their other stable positions (not shown). When the coil 52 is pulsed the member 86 is repelled and strikes a buffer 94 on the member 92 to assist in upward movement as the actuator moves to the position shown. The members 86 and 92 may have conductive layers on an insulating base.

Patent GB-2022906-A (GB)
Title: Improvements in or relating to electronic control systems for recording and/or playback apparatuses of the reverse type
IPC: G11B15/02
Filed: 1979-06-11
Abstract: In an electronic control system for a reversible tape recording and/or playback apparatus, a detector 1 produces a logic 0 or 1 output according to whether the tape is stationary or moving and is connected to a logic block 2 giving a 1 or 0 output according to whether the tape stopped while before it was moving or stopped while before it was stationary. At each 1 to 0 transition of the block 2 output, a monostable 3 produces an output pulse which momentarily de-energises a relay R1 to effect automatic reversal of the tape drive direction. In a first state of a function programmer 7, switches 4 and 5 are open and the tape is continuously reversed at each end. With programmer 7 in a second state, switch 4 is closed, 5 open and 6 at I so that at the first tape end, relay R1 reverses the tape direction, whereas at the second tape end relay R1 reverses the tape direction and, due to divide-by-two circuit 8, relay R2 ejects the tape cassette and transistor 24 turns off motor 23. In a third state of programmer 7 the cassette is ejected and motor 23 turned off at each end of the tape. A tape head position- sensing switch S4 (Fig 3) prevents cassette ejection before the head has been extracted therefrom. Detector 1 may be of capacitive type (as in application no. 7907419). <IMAGE>

Title: Valving in aircraft undercarriage shock absorbers
IPC: B64C25/60
Filed: 1980-01-11
Abstract: In a combined shock absorber jack assembly for an aircraft undercarriage, a sleeve 32 fixed within the end of a hollow piston rod 3 which is slidable within a cylinder 2 has a radial passage 50 opening outwardly of the sleeve 32 into an annular hydraulic fluid chamber 52 defined between the piston rod 3 and the sleeve 32 and communicating with the hydraulic fluid chamber 9 of the cylinder 2. A tubular valve member mounted within the sleeve 32 has two portions 60, 58 of different outside diameters for cooperating with two portions 49, 48 of the sleeve 32 of corresponding different inside diameters to form a differential piston and is acted upon by resilient means 64, the radial passage 50 being closed inwardly of the sleeve 32 by the portion 58 of the tubular valve member 56. In the event of a heavy landing of the aircraft producing forces driving the piston rod 3 into the cylinder 2 which are higher than the normal, the pressure applied to a shoulder 66 of the differential piston displaces the tubular valve member 56 against the force of the resilient means 64 to permit a supplementary flow of hydraulic fluid from the chamber 9 towards a gas chamber 15 in the hollow piston rod 3 such supplementary flow being additional to that which occurs through a permanent compression-mode throttle orifice 44. The cylinder 2 is also the rod of the undercarriage retraction jack cylinder (not shown). <IMAGE>

Title: Extrusion Die for Producing Plastics Net or Net-like Products
IPC: B29C48/07
Filed: 1980-03-14
Abstract: The die comprises members 2, 3 having respective die orifices 4, 5 through which plastics material is introduced in a downward direction (as seen in the figure) the die members being relatively displaced during extrusion (as indicated by the arrows). Rolling elements 8 are sandwiched between the members 2, 3 to provide rolling frictional contact with the die members, thus avoiding the deleterious effects of direct sliding frictional contact between the die members. The elements 8 may be held in a retainer 24 and may lie in an open channel 6 connected through passages 9, 10 with the die orifices 4, 5 so that the elements 8 are lubricated by the plastics material. Alternatively a closed channel (containing lubricant) may be used. The channel may be formed in both the die members 2, 3 or in one of these. <IMAGE>

Said coupling 3 is able to move freely upwardly on the seat frame rods, but the pin 6 must be released from a ratchet groove by means of an elastic tongue 5, 7 to allow movement of coupling 3 downwardly. The pivotable intermediate portion is made up from disc-like portions interconnected by webs 10.   <IMAGE>
Patent GB-2060321-A (GB)
Title: Speech synthesizer
IPC: G10L13/08
Filed: 1980-09-29
Abstract: A speech synthesizer is disclosed with the capability of stretching and compressing the speech time base without changing the pitch of the synthesized speech. One frame of speech is represented during a given time base by LPC parameters which are sampled a constant number of times per frame and stored in memory. Speech is synthesized by fetching each of the stored LPC parameters for each frame and subjecting the parameters to interpolation, synthesizing the interpolated parameters and converting the synthesized parameters to analog format. A decrease in the speed of the reproduced speech is produced by lengthening the time interval of interpolation between the fetching of each of the stored LPC parameters which have been previously stored for each frame. An increase in the speed of the reproduced speech is produced by decreasing the time interval of interpolation between the fetching of each of the stored LPC parameters which have been previously stored in each frame.
