Title: Improvements in or relating to liquid pressure braking systems
IPC: B60T11/224
Filed: 1941-02-07
Abstract: 547,041. Hydraulic master cylinders. HYDRAULIC BRAKE CO. Feb. 7, 1941, No. 1667. Convention date, Feb. 7, 1940. [Class 103 (i)] In hydraulic master cylinders, for operating brakes, comprising a relatively large diameter piston effective for moving the brake shoes into contact with the drums and a smaller diameter piston by which the braking pressure is applied, the larger piston is gradually rendered ineffective during an operation by the provision of a restricted passage connecting the chamber in front of the larger piston with the reservoir. Relatively large and small pistons 66, 82 move in chambers 32, 34 of the cylinder 24. In the release position of the pistons, these chambers communicate with the reservoir 10 through ports 38, 28. A chamber 70 between the piston 66 and a head 72 is constantly open to the reservoir through a passage 26. A restricted passage 88 and a passage 86 closed at one end by a plug 92 connects the chambers 32,70. The passage 88 is restricted by a wire inserted therein. During initial movement of the pistons to apply the brake, liquid is displaced by the large piston 66 from chamber 32 through passages 94 in piston 82 past the sealing cup 96 to chamber 34 thence to the brakes by the port 42. Liquid also flows slowly from the chamber 32 at this stage through the passage 88 to the reservoir. A large volume of liquid is thus displaced from chamber 34 but when due to the application of the brake shoes to the drum the pressure of the liquid rises substantially, the flow through the passage 88 increases so that the pressure of the liquid is gradually transferred from the piston 66 to the smaller piston 82. During retraction of the pistons liquid is drawn into the chambers 34, 32 from the reservoir through passages 76, 94 in the pistons and past the sealing cups 78, 96, excess subsequently returning to the reservoir through ports 38, 28.

Title: Esters of the androstane series and process for their manufacture
IPC: C07J1/00
Filed: 1961-01-16
Abstract: The invention comprises (1) 3-monosulphobenzoic acid esters of 3, 17-dihydroxy-5a -androstanes or -D 5-androstenes which contain in the 17a -position a saturated or unsaturated aliphatic hydrocarbon radical and their salts with alkali metals, alkaline earth metals and amines and their preparation by esterification of the parent diols with reactive derivatives of the monosulphobenzoic acids; and (2) 17a -methallyl-D 5-androstene-3b , 17b -diol and 17a -isobutyl-5a -androstane-3b , 17b -diol.  The last-named compounds may be prepared by reacting D 5-androstenolone acetate with methallyl magnesium chloride and hydrolysing the product, to give the methallyl compound, and reducing this or its 3-acetate to give the isobutyl compound or its 3-acetate (which on hydrolysis gives the 3-ol). Examples are given. The sulphobenzoic acid esters of the invention, which are stated to have antiallergic and antianaphylactic action may, as their salts, be dissolved in water to give stable solutions which may be sterilized.

Title: Apparatus for monitoring industrial plant
IPC: G06F19/00
Filed: 1973-01-12
Abstract: 1380021 Monitoring apparatus HOOGOVENS IJMUIDEN BV 12 Jan 1973 1822/73 Heading G1J [Also in Division G4] In apparatus for monitoring the operation of an industrial plant, contacts, each of which is sensitive to a failure of apparatus or a change of a parameter in a process, are grouped in clusters which are connected to a respective diode matrix, the signals from which are continuously scanned by a computer, any change in the state of a contact being immediately displayed on a visual display device for a transitory period, and recorded on a teleprinter. An aural warning may also be given. An auxiliary panel is associated with each matrix so that the correction of any fault may be checked on site whether or not the computer is in operation. Each contact is connected to a row and a  column of a matrix via a diode. Voltage pulses are applied in rapid succession to AND gates connected to each column, and also to each row. Thus, in the event of a contact closing, signifying a plant fault, the AND gate receives two pulses, resulting in the transfer of a binary signal to the computer. Vital computer parts are duplicated, and the disappearance, location and type of breakdown may also be recorded for later analysis. Further, the computer may be provided with means enabling a review of the condition of all or part of the plant and means for the restarting of a monitoring program after a power failure, the computer having a "memory" which is unaffected by a power failure.

Abstract: 1378253 Moulding paste such as minced meat G ANNEMANS 17 Jan 1972 [22 Jan 1971] 2133/72 Heading B5A A manually operated mould 1 for producing rounded portions from a paste such as minced meat or mashed potatoes, is bell-shaped with its inner wall covered with a flexible sheet 4 of a non-adhesive material such as polyethylene, which is loose relative the mould wall and is attached to the mould by a rubber band 9. The sheet is attached to an ejector 5, slidable in a tubular part 8, by a plug 6 secured to the sheet and fitting a recess in the ejector. The mould is pressed against a paste supply until its edges 2 engage the paste-supporting surface whereupon it is given a reciprocating rotating movement; after raising the mould the shaped portion is removed by depressing the ejector. The mould may be used with a dish 10 covered with a non- adherent flexible sheet 14 which receives the paste supply and includes a groove 13 to receive the mould edges 2. An air vent 15 is provided. Alternatively, in order to provide a ribbon of paste, the mould is of double cone shape, the apexes of which face each other; the mould is rotated about its axis of symmetry whilst pressure is applied to the paste by the base edges of the cones. A similar ribbon may be formed by the use of a mould in the shape of an open-ended inverted trough. In both of the latter embodiments the paste to be shaped is covered with a flexible non-adhesive sheet.

Abstract: 800,138. Discharging receptacles by liquid pressure. LAPEYRE, J. M. Jan. 21, 1957, No. 2139/57. Class 102(2). [Also in Group XVII] An apparatus for discharging a filled collapsible tube 19 by liquid pressure comprises a container 10 for housing the tube 19 in a surrounding liquid, a resilient diaphragm 15 in one of the container walls adapted to be pressed inwardly by hand, and an adjoining hydraulic fluid reservoir 11 communicating with the container 10 through a check valve 14. On depressing the diaphragm 15 the check valve 14 closes and the resulting rise in pressure in the liquid in the container 10 acts on the tube 19 to extrude some of its contents through its nozzle 20. On releasing the pressure on the diaphragm 15 the check valve 14 opens to permit more liquid to enter the container 10. The nozzle 20 extends through an opening 18 in the container base and a gate cap 21 is secured on to it to secure the tube in position. The gate cap 21 has an orifice 23 normally closed by a swinging gate valve 24.

[Classes 54 and 135.] The upper chamber of a gas meter casing is divided by a partition 13 into gas inlet and outlet chambers, each containing four valves communicating directly or through passages 12 with the four measuring chambers. The valves are operated by the engagement of cams 31 on a shaft 15 arranged parallel to the wall 2 between the inner measuring chambers with rollers carried by levers 20, 21 mounted on rods 19, 18. The shaft 15 is rotated by crank and connecting-rod mechanism 25 on shafts 8 which form part of the parallel-guiding mechanism 6 .. 9 for the diaphragms 3. The shafts 8, 15 pass through partition apertures rendered gastight by stuffing-boxes 16, 23 comprising a collar or flange 28 and washer pressed against a bearing surface on the partition by a spring. The inlet and outlet connections are preferably arranged horizontally. The valve discs each consist of a rigid disc 35 having a soft bearing surface and pivoted to a threaded spindle 34 by a pin 36. The pin hole in the spindle and the hole in the valve collar 37 are enlarged towards their ends to allow the valve to move angularly relatively to the spindle.
