Title: Pressure-Responsive Control Apparatus
IPC: C08F10/00
Filed: 1966-05-04
Abstract: 1,152,792. Automatic fluid control. SOC. NATIONALE DES PETROLES D'AQUITAINE. May 4, 1966 [May 6, 1965], No. 60630/68. Divided out of 1, 152, 791. Heading G3R. Control apparatus for controlling the operation of a valve controlling the passage of fluid in a system comprises a voltage-frequency converter, means responsive to fluid-pressure in the system for converting this pressure into numerical values, a counter for integrating these values, a memory counter which is adapted to vary the capacity of the first said counter at will, and means including a logic element for controlling the operation of the valve in dependence upon a function of the pressure. The apparatus may be used to control the time of opening and duration of opening of the outlet valve of a high pressure ethylene polymerization reactor. In a preferred embodiment a pressure measuring instrument 11 supplies an analogue signal to a numerical analogue converter 12, pulses from 12 are counted in counter 14, when 14 is nearly full the penultimate pulse changes the state of the flip-flop unit 20 and opens the gate 21. The counter 23 is then filled to a certain value. The last pulse gives a signal causing change of state of the flip-flop unit 15 and cause the valve 16 to open. The same signal closes gate 21 and opens gate 24. The content of the auxiliary counter 23 is thus fixed and the counting back starts. When this is complete an end of counting signal is sent to the second input of the flip-flop unit 15 and this effects closing of the valve 16.

Abstract: 1,271,876. Non-contact-making switches; transistor bi-stable circuits. CONTRAVES A.G. 24 Dec., 1969 [21 Jan., 1969], No. 62907/69. Headings H3B and H3T. [Also in Division G1] A non-contact making switch comprises a bi-stable transistor circuit in which switching from one stable state in which transistor 1 is in unsaturated conduction and transistor 1<SP>1</SP> is blocked to the other stable state in which transistor 1<SP>1</SP> is in unsaturated conduction and transistor 1 is blocked is initiated by variation of a phase-shifting impedance (e.g. capacitance 7 or inductance 8) which causes transistor 1 to begin to oscillate, whereupon its conductive state becomes unstable and the circuit switches over to its other stable state. As shown in Fig. 6, one variable capacitance 7 is provided. The variation of the basecollector capacitance of transistors 1, 1<SP>1</SP> between the conductive and blocked states assists the switching. In Fig. 1 (not shown) capacitance 7<SP>1</SP> is also variable, preferably the arrangement is such that a common control (Fig. 2, not shown) increases C7 while decreasing C7<SP>1</SP> and vice versa. Arrangements are described using a single self-inductance (8, Fig. 5, not shown) or two self-inductances (8, 8<SP>1</SP>, Fig. 7, not shown), variable by a rotatable member (Fig. 8, not shown) carrying a conductive plate (84) into and out of proximity with the inductance. An arrangement using two variable mutual inductances is described with reference to Fig. 3 (not shown), the mutual inductances being variable by rotating an axle to move a conductive plate (93, Fig. 4, not shown) between the coils of the mutual inductance. A plurality of such circuits may be controlled by rotation of a common selector.

To send a $5 bet in the win pool on competitor No. 2, for example, keys 7 and 19 are depressed, operating relays COA, YSW and CBW which cause the bet to be registered by total adding machine relay YTW and competitor adding machinerelay YBW to register a$5 bet. To send a place bet of$2,$5, or$10 stake key 9, 10 or 11 is depressed to bring up relay COB which connects the ticket issuing machine to the place stake and competitor relays, commutator and adding machines which operate in the same manner as for win bets. To send a show bet on these values$2,$5 or$10 stake keys 12, 13, or 14 are depressed and any of these keys bring up COD relay which connects the machine to the show equipment and operates as for win or place. To send a combined bet of$2 on competitor No. 1 stake key 15 and competitor key 18 are depressed. Key 15 brings up relay COE over back contacts tc2 which changes over contact coel in the circuit of relay TC and operates relay COA over coe2 front, coe2 back. As the $2 win bet is registered COX operates and releases COA at cox2 and operates COB via cox3 front, coy2 back. This releases the win commutator so that relays XTW and XAN restore. Relay OP also releases unless the place commutator happened to be on the ticket-issuing machine segment in which case magnet LMP will operate via cob2 front in series with relay OP which will hold. The two adding-machine relays operate to register the bet and the second transfer relay COY operates, releasing COB at coy2 and operating COD via coy3. Operation of TC releases relay OP, the commutator, and the adding-machine relay S to print and issue the ticket.

Abstract: 730,909. Roller weighting arrangement. SCHIESS AKT.-GES. Jan. 22, 1953 [Jan. 23, 1952], No. 1849/53. Class 120(2). A spring loading device for twin pressure rollers is characterised by the fact that the pair of pressure rollers is maintained axially parallel with the lower roller solely by a holding member or arm which is prevented from being displaced laterally relatively to the lower roller and the upper pressure rollers and is prevented from turning about the axis of the lower roller by an abutment. In the embodiment shown a spring loading device is applied to a pair of pressure rollers 10 above a lower roller 1. The holding member or arm 7 of the loading device engages closely an annular recess 4 of roller 1. The other end of member 7 is formed into a slide guide 7<SP>1</SP> in which a slide piece 8 which is prevented from turning within its guide can move against the action of spring 6. The piece 8 is formed with a bearing groove for the shaft 9 of the rollers 10 so that the latter are held parallel with the lower roller 1. To prevent rotation of the loading device about the roller 1 a heel 11 abuts a fixed stop 12. Bearing bushes or needle bearings may be provided between the member 7 and the lower roller 1. In a second embodiment, by off-setting the line of action of the spring 6 from the axis of the lower roller 1. the pressure rollers are subjected to a restoring force as soon as they tend to twist around a vertical axis thus further helping to maintain the axes of the rollers parallel. In another embodiment a suitably shaped leaf spring is used as a holding and loading device.

Title: Seal of piston of pressure device
IPC: F16J15/32
Filed: 1978-07-27
Abstract: A seal 1 is fitted over the front end of a piston 4 to define a cavity 6 between the seal 1 and the front face 5 of the piston. In use, fluid pressure on the front face of the seal 1 causes deformation of the forward part 2 of the seal to effect radial expansion of the seal. Owing to its shape and material it is made of, the seal ensures a variable sealing thrust on a surrounding cylinder proportional to the pressure acting on the piston, thus enhancing the useful life of the seal. The cavity 6 may be filled with gas or solid, elastic material. <IMAGE>
