Title: Improvements in variable stroke radial cylinder pumps or motors
Inventor: HOLBERTON BERNARD VICTOR
IPC: F01B1/06
Filed: 1957-05-09
Abstract: 831,349. Radial cylinder pumps. DOWTY FUEL SYSTEMS Ltd. May 8, 1958 [May 9, 1957], No. 14804/57. Class 102(1). [Also in Group XXIX] The pistons of a radial cylinder pump engage, through shoes 6 and spherical bearings 5, a track ring 7 which is arranged for controlled limited rolling engagement with an abutment 31, whereby the stroke of the pistons may be varied, toothed engagement being provided by gear teeth 11, 12 between the track and abutment. In operation the reaction of the pistons holds the track against the abutment 31 which may be flat as shown or other desired shape ; the gear teeth may be arranged to absorb the reaction force. A further diametrically opposed abutment 29 is also provided. The track 7 is moved by means of a rack 14, which may be at an angle to the abutment 31, engaging teeth 13 on the track 7. The rack is formed with a piston 16 subjected to the outlet pressure passing through an orifice 34 to an outlet 35 controlled by a vent valve controlled by the fuel supply governing mechanism of a gas turbine engine supplied with fuel by the pump. The piston 16 may alternatively be connected to the track 7 by a pivoted link. The abutment 31 may be slidable to cause rolling of the track ring. The block 2 has two banks of cylinders and one end face abuts a ported valve 19. The other end of the block is pressed by an annular piston 26 in a cylinder 25 connected to the outlet port.

Title: Arrangement for shifting the multiplicand in a calculating machine
IPC: G11C19/00
Filed: 1951-06-21
Abstract: 723,774. Digital electric calculating-apparatus. COMPAGNIE DES MACHINES BULL. June 21, 1951 [June 26, 1950], No. 14809/51. Class 106 (1). In an electronic machine for automatically performing the multiplication of two decimal numbers, a registering arrangement comprises a multiplicand register adapted to register digits of successive decimal orders on respective groups of units corresponding to predetermined coded values, groups of switching devices each associated with one register group, a first pulse generator for applying a clearing pulse to each register group, and a second generator for applying to each group of switching devices a differently-timed pulse to shift to the associated register group the digit registered on an adjacent group. The multiplicand register shown comprises five decimal denominations U, D, C, M, DM, each consisting of four hard-valve trigger pairs 20 representing coded values 1, 2, 4, 8. Each trigger, except in the highest denomination DM, applies an output potential over a line such as 28 to a gate circuit 26 so that if it is in the " on " state (represented by shading of the lower portion and of an associated neon indicating lamp 21) the gate will be open (represented by horizontal instead of vertical lines) to allow an operating pulse to be applied from a distributer D1 to the corresponding trigger in the next higher denomination. The distributer supplies pulses to the gates of denominations M, C, D, U in that order, which pulses are timed to be interspersed with, and a half-step in advance of, resetting pulses from a distributer D2. In operation, the distributers are operated to effect denominational shift after each multiplication of the multiplicand by a digit of the multiplier. The multiplication may be effected by repeated addition employing an electronic accumulator similar to that described in Specification 679,993. In a modification (Figs. 3a-3c, not shown) in which shift occurs simultaneously in all denominations, the distributers are omitted and each valve-registering trigger (A) has a second trigger (B) associated therewith. When resetting pulses are applied simultaneously to all triggers (A), the number registered is transferred to triggers (B), and on the subsequent resetting of triggers (B) the number is sent to the corresponding triggers (A) of next higher denomination.

Patent GB-871221-A (GB)
Title: Recovery of antibiotics by means of ion-exchange resins
IPC: B01J47/00
Filed: 1958-05-09
Abstract: Increased yields and facilitated recovery are obtained by adding to the fermentation broth during the fermentation a particulate ion exchange resin capable of adsorbing the antibiotic, allowing the fermentation to proceed in the presence of the resin, separating the spent fermentation broth and mycelium from the ion exchange resin and eluting from the ion exchange resin the antibiotic adsorbed on it. The resin is added to the broth at a period of time from the beginning of the fermentation or preferably after 48 hours to 1 hour but preferably 24 hours before the harvest of the broth.  1 to 5% by volume of resin is used.  The resin is preferably sterilised prior to addition to the broth.  If heat cannot be used, the resin may be sterilised by treatment with an antiseptic such as aqueous alcohol. In general, 10-200 mesh and preferably 35 to 100 mesh size resin is used.  In recovering the antibiotic, it is preferred to dilute the broth with water and to separate the resin particles from the mycelium and spent broth by means of a suitable screen especially a vibrating screen.  The antibiotic is eluted from the resin by means of an aqueous eluting agent containing an electrolyte.  For acidic antibiotics such as novobiocin and penicillin, there is used a basic, highly porous, anion exchange resin.  For basic antibiotics such as streptomycin, neomycin and eulicin, there is used an acidic, highly porous, cation exchange resin.  In one example, Dowex 1-X2 resin (quaternary ammonium groups attached to a styrene divinylbenzene matrix) on the chloride cycle, previously sterilised by treatment with anhydrous ethanol, is added to a novobiocin fermentation broth at various stages in the fermentation, the resin is removed by a 70 mesh screen and the novobiocin eluted therefrom by means of 16% aqueous hydrochloric acid in methanol.  In another example, Duolite C25 resin (sulphonated polystyrene divinylbenzene cation exchange resin) on sodium cycle, previously sterilised with 70% aqueous ethanol, is added to a neomycin fermentation broth 48 hours after the inoculation, the resin separated on a 28 mesh screen and the neomycin eluted with aqueous ammonia.

Title: Rope terminal fitting
IPC: F16G11/00
Filed: 1974-04-05
Abstract: 1459589 End fittting for ropes BRIDON Ltd 4 July 1975 [5 April 1974] 15136/74 Heading D1T A rope terminal fitting that can be used to couple an anchor line to an anchor contains a pyrogenic change that can be used to cause the fitting to release the anchor line from the anchor. According to the invention the fitting comprises two end parts 1, 10, Fig. 2, releasably interconnected by an intermediate part 6, the end part 1 being adapted to receive the end 3 of the anchor line, there being a cavity between the end parts 1, 10 in which a pyrogenic charge 13 is contained and which, on ignition, causes the intermediate part 6 to lose its strength and so permit the end parts to part company. In Fig. 2 the intermediate part 6 is screwed into the end parts 1, 10 to clamp a water tight casing 14 therebetween. The pyrogenic charge 13 is within the casing 14 and surrounds the intermediate part 6.  The cable 3 contains electrical conductors 20, 21 coupled to a converter 19 that converts a continuous low-power input into a pulsed high-power output. The output of the converter 19 is coupled to ignition elements 27, 28 that extend into the charge 13. The converter 19 supplies either continuous pulses to raise ignition elements 27, 28 to a temperature of 1100‹C (at which the charge 13 ignites); or separate high energy pulses to ignite a primary igniter within the charge. Alternatively, the converter can be omitted if sufficient power can be transmitted along the rope 3. The fitting contains sealing rings 15, 16, 32, 33. Fig. 6 shows a modified construction in which the intermediate part comprises a plurality of spaced, parallel elongate elements 34' each encompassed by an individual pyrogenic charge 13'. The charges 13' are separated from each other by partitions 44 but are interconnected by fuses 46. In addition each charge is provided wiith its own ignition arrangement in order to ensure a fail-safe system in which (because of the interconnecting fuses) the whole pyrogenic charge will be ignited even if all but one of the ignition arrangements fail. When the pyrogenic charges ignite they reach a temperature of about 6000‹C.

Abstract: 581,686. Radiolocation. BRITISH THOMSON - HOUSTON CO., Ltd., and BOWEN, A. Nov. 25, 1941, No. 15201. [Class 40 (v)] [Also in Group XXIX] To cause synchronous oscillating movements of objects such as parabolic mirrors about their axes, gears 1, 1<1>, Fig. 1, on the mirrors are oscillated by racks 2, 2<1> reciprocated by pistons 4, 5 ; 4<1>, 5<1> arranged in cylinders 6, 7, 6<1>, 7<1> connected in cascade and adapted to receive pressure fluid delivered alternately by master cylinders 10, 10<1> in which reciprocate pistons 9, 9<1> on a rod reciprocated by a cam 12. Pipes 11, 11<1> deliver pressure liquid alternately to the cylinders 6, 6<1>, and when delivered to cylinder 6 piston 4 moves to the right and the consequent movement of piston 5 causes liquid to flow through pipe 8 to cylinder 7<1> and move piston 5<1> also to the right and pressure liquid returns via pipe 11<1> to the cylinder 10<1> causing movement of piston 9<1> to the left. Relief valves 18, 18<1> are provided in the delivery pipes of the master cylinders and a relief valve 19 in pipe S opens at a lower pressure than the valves 18, 18<1>. The supply of liquid is maintained, by a delivery pipe 16 connected by non-return valves 17 to the pipes 8, 11, 11<1>. In a modification, Fig. 2, which is applied to reflectors for ultra short waves emitted from an aircraft for locating a remote object by the radio-echo principle, the receipt of a reflected wave being indicated by means such as a cathode-ray tube, the reflectors 21, 21<1> are mounted in gimbals and are given movements about two axes at right angles to each other so as to execute a scanning movement. Azimuth movements are effected by master cylinders M<1>, M<2> and cascade cylinders 22, 22<1> operating as in Fig. 1 and elevation movements are given intermittently by master cylinders M1<1>, M2<1> provided with pistons operated by cams 24<1>, 25<1>, associated with a cam 30 which gives reciprocating movements to the cylinders and so controls the output of liquid pressure to the cylinders 23, 23<1> which alter the elevation of the reflectors in such a way that changes in elevation take place after a sweep in each direction. The two cam-shafts are driven by electric motors 26, 26<1> through friction gearing and discs 33, 34 formed with slots 35 and rollers 36 are used to keep the shafts in synchronism. When the elevation of an object is obtained, the motor 26<1> can be de-energized and the motor 26 controlled by a potentiometer operated by hand to enable the exact position to be determined. To prevent interruption of emitted waves by an object such as the nose of an aircraft fuselage, a switch may be operated to change over the emission of rays from one mirror to another in a predetermined angular position of the mirror. Fixed pistons and movable cylinders may replace the movable pistons and fixed cylinders.
