Abstract: 602,612. Reciprocating pumps. PRECISION DEVELOPMENTS CO., Ltd., and OLAH, G. July 24, 1945, No. 18895. [Class 102 (i)] The delivery of a pump 35 is controlled by retaining the suction valve, of the lift type, open during a part of the delivery stroke by means of an abutment 8. As shown in Fig. 2, the abutment 8 is actuated by a piston rod 37 and the cylinder 36 is connected by a pipe 38 to two valves 39, 40 which control the supply and exhaust respectively of pressure fluid to cylinder 36. The valves 39, 40 are rotated by a chain drive 43 from the pump and a differential gear 44 may be included to vary the phase relationship between the pump piston and the opening of the suction valve. This control is preferably obtained by adjusting the valves 39, 40 axially and providing inclined ports on them. Alternatively this control could be obtained electrically.

Abstract: 1495769 Automatic control of rolling mills VEREINIGTE FLUGTECHNISCHE WERKEFOKKER GmbH 6 May 1975 [21 May 1974] 18936/75 Heading G3R The roll gap in a mill 1 is controlled in response to the difference between the actual value X of the gap and a desired value W, "corrected" by a signal obtained from a measurement of the width of the material being rolled, the rolling force and rate of change of the rolling force. The first parameter is divided into the second at 6, the quotient being multiplied at 9 by the rate of change of the force (obtained by high and low pass filters 7, 8). The correction signal is limited at 10 by Zeners 11, 12 to prevent the control saturating e.g. in the event of strip breakage. The high pass filter characteristic is modified by switching device 13, 14 during threading.

Title: Improved means for connecting overhead high tension electrical cables to the insulators of transmission towers
IPC: H02G7/05
Filed: 1956-06-19
Abstract: 800,980. Suspending cables. FRASER, H., and CANTLAY, W. G. Dec. 13, 1956 [June 19, 1956], No. 18957/56. Class 36. A cable is suspended from the insulator of a transmission tower by a two-part device, the upper part 11 being pivotally secured to the insulator, and the lower pent 10 carrying the cable and being supported by the upper part, the two parts being normally held together by a locking device which yields if the pivotal movement exceeds a predetermined extent which will occur if the cable breaks at one side of the device. The lower part 10 comprises a cable clamp 12, 13, two upright lugs 14, lugs 15a formed on the lower end of a suspender 15 and a pin 16 passing through the lugs, which have interfitting projections 17 and recesses 18 to prevent relative rotation. At its upper end the suspender 15 carries two rollers 19 mounted on a pin 20. The upper part 11 is pivotally attached to the insulator and comprises an open-ended housing 26 provided with a pair of curved tracks 22 on which the rollers 19 rest. A transverse pivotpin 23 fits within a slot at the top of suspender 15 which enables the suspender to swivel and the rollers to move along the tracks. A shear pin 25 passes through the suspender 15 and a pair of lugs 24a on the housing 26. Normally the rollers rest centrally on the tracks, but if the cable breaks there is a sudden pull on the cable to one side of the clamp, resulting in the suspender 15 pivoting about the pin 23, causing the pin 25 to shear. The rollers then move along the tracks and pass off the ends of the tracks and through the end of the housing 26, when the suspender 15 complete with clamp and cable will fall to the ground. In a modification the tracks are formed in the upper part of the housing, which is embodied in the lower part 10, the tracks bearing on the rollers which are pinned to the upper part 11.

Title: Computer circuits

Filed: 1961-05-25
Abstract: 968, 704. Parity checking circuits. RADIO CORPORATION OF AMERICA. May 22, 1961 [June 9, 1960], No. 18999/61. Heading G4A. A circuit which provides a parity check for a binary word is inhibited from operating if any digit of the binary word is absent. The circuit may be applied to generating or checking parity. The arrangement shown in Fig. 7 is for checking the parity of an input word consisting of 27 binary digits plus a parity bit. The word to be checked appears in true form on a "bus 1" as bits A 1 -A 27  P 1 , and in complement form on "bus 2" as bits @P 2 . These bits are applied in threes as snown to a first level of logic nets 3-20, nets 3-11 (Fig. 2, not shown) each producing "O" output only when there is information present in the three bits applied thereto. The outputs C; of nets 3-11 are applied to control respective nets 12-20 (Fig. 3, not shown), which produce outputs D i  =0, E i =1 when the three "A" input bits examined include an odd number of "1" '5 and an output Di = 1, E i  = 0 if there is an even number of ones. A second level of logic nets 21-23 (Fig. 4, not shown) examines in threes the outputs of the first logic net level and produces outputs F, G, the net 21, for instance producing an output F 1  = 0, G 1  = 1 when there is an odd number of "1" 's in the E digits examined. A third logic level comprising net 24 (Fig. 5, not shown) examines the F and G digits, and when there is an odd number of "1" 's in the G digits, produces an output H = 0, I = 1. Outputs H, I are applied to a stage 25 (Fig. 6, not shown) which compares H and I with the parity P 1  of the original word, and the complement parity P 2 . If the i'th input digit is absent, then A i , = B i = 0, and C i = 1 so that the corresponding logic net 12-20 is inhibited and produces outputs D and E which are both "0". Similarly the associated F and G are both "1" and J and K are both "0" thereby indicating an absence of a bit in the input word. The arrangement described can also be employed as a parity generator by applying outputs H and I to generator circuit (Fig. 8, not shown) to produce a parity bit P 1  and its complement P 2 , the generator circuit also having a third output which indicates when an input bit is missing. The nets and circuit described employ NONE gates.

Title: Process for the preparation of alkyl aluminium compounds
IPC: C07F5/06
Filed: 1962-05-17
Abstract: In the growth reaction between a low molecular weight alkyl aluminium compound and a gaseous olefin carried out in at least one batch reaction zone at elevated temperature and pressure, the reactants are introduced into the reaction zone, circulated through an external heat exchanger at high velocity until they reach reaction temperature, the heat exchanger is then converted to a cooling zone through which the contents of the reaction zone are continuously circulated to remove exothermic heat of reaction thus providing a homogeneous reaction mass, intimate liquid-gas contact and maximum reaction rate, and removing the reaction product from the reaction zone.  Preferably a plurality of reaction zones is used.  Gaseous olefin is removed from the product in flash zones of reduced pressure, the liquid product from the second flash zone being the required alkyl aluminium growth product.  Flow diagrams of the process are given.

As shown, the tube is formed on a rotating mandrel 4 and the inner layer 1, of polyester or epoxy resin impregnated glass fibre rovings, is wound thereon. In a first arrangement the inorganic particles, e.g. of sand or clay 50% with a diameter exceeding 0À5 mm. and preferably 80% in the range 0À5-3À0 mm., are delivered from a hopper 6 and shoot 7 above the mandrel. Thermosetting resin 9 is delivered under pressure through an atomizer to coat the particles 11 before they hit the layer 3. Either the particles or the resin are heated so that the layer 3 is formed at a temperature of at least 23 C. A band 5 of glass fibre fabric or non- woven material is wound about the layer 3 to compress the coated particles into contact with each other. The outer layer 2 of glass fibre rovings and resin is then wound on and the composite tube is subsequently cured by heating. In another arrangement the intermediate layer consists of a wound web of non-woven glass or plastics filamentary material coated with filler particles and resin.
