Title: Device for measuring, moulding and delivering plastic materials
IPC: B29C48/09
Filed: 1957-12-03
Abstract: 826,470. Moulding butter &c. ELLING- HAUS, W., and HILGERS, H., [trading as BENZ & HILGERS MASCHINENFABRIK]. Dec. 3, 1957 [Dec. 6, 1956], No. 37614/57. Class 87(2). [Also in Groups XVII and XVIII] Apparatus for delivering and moulding measured quantities of plastic or semi-fluid substances such as butter or ice-cream comprises one or more measuring cylinders 9 which are filled from a supply pipe 1 when a slide 6 is opened and are then moved to a discharge position at which the contents of the cylinder are ejected by a piston 10 and any residue on the face of the piston is removed by a scraper 11. The cylinders are of the same cross-section as packages into which the shaped material is ejected and may be carried by a table 8 on a shaft 7 indexed step by step by gearing 24, 25 from the shaft 23 of a packaging table 22. A pair of pistons may be interconnected by a spring 18 which runs over a pulley 16 on a support 15 carried by the shaft 7 and holds the pistons against an adjustable control lever 19 or 20. At the filling position, a nozzle 3 on the supply pipe is raised to seal against the bottom of the measuring cylinder and the slide 6 is opened so that the cylinder fills until the piston 10 moves the lever 19 to a stop position. At the same time, the walls 28a and bottom 28b of the packaging cell are raised so that a package 29 in the cell surrounds the lower end of the cylinder at the discharge position and then, as the piston 10 is moved down by the lever 20 to eject the contents of the cylinder, the cell walls and bottom move down against the same rate as the piston to ensure uniform filling of the package. At the end of the discharge operation, the stirrup-shaped scraper 11 is moved over the face of the piston against the action of a return spring, the slide 6 is closed, the nozzle 3 is lowered and the spring 18 moves the piston 10 further upwards. The filled cylinder is then rotated to the discharge position and the discharged cylinder brought to the filling position. An oblique arcuate holder plate 21 engages under the shoulder 10a of the piston of the filled cylinder so that it is further raised and premature delivery does not occur. A single measuring cylinder may be given a reciprocating motion between the filling and discharge positions.

Title: Data transmission
IPC: H04L27/34
Filed: 1975-09-12
Abstract: 1504609 Data transmission HYCOM Inc 12 Sept 1975 [16 Sept 1974] 37622/75 Heading H4P In a digital data transmission system, each of a plurality N of data symbols is transmitted as a pair of in-phase (I) and quadrature (Q) components which, when plotted on a graph with I as abscissa and Q as ordinate, define a vector carrying the respective information in one of the symbols, the ends of the vectors constituting an array of N points at the centres of N close-packed circles of equal diameter, where N is at least 4. As shown, N equals 8, the vectors are numbered 0 to 7 and the circles are designated with consecutive odd numbers 51 to 65. The length of the vectors 0 to 7 is associated with the amount of power needed to transmit the symbols whilst the separation between the vectors represented by the diameter of the circles is associated with ease of detection, and the Specification shows how the described arrangement results in minimum length associated with maximum separation to give improved transmission qualities. The said points are located in respective ones of N areas bounded by tangents to the touching circles, e.g. the end of vector 2 is in an area bounded by tangents 109, 103, 115, 113 and 111. On reception, signals are processed to determine the I and Q components. Logical and linear arithmetic conditions are then applied to these components to assign them to one of the N areas. Deficiencies in the transmission line may distort the vector components which will then not define vectors having the same values as the originally transmitted vectors 0 to 7. However, any vector detected within the associated boundary area will be presumed to be the true vector, and thus the effects of distortions are minimized. Suitable arrangements for the receiver are described with reference to Figs. 7 to 9 (not shown), and the system as a whole may be similar to that described in Specification 1,459,501.

Abstract: 1386039 Knitting BILLI SpA 10 Aug 1973 [12 Aug 1972 16 Nov 1972] 37975/73 Heading D1K Tights or the like are knitted by forming a closure member ("a closed toe") which acts as a gusset 11, knitting one leg 13 and attaching it to part of the circumference of the gusset, knitting the body 17 on to the leg 13 and gusset 11 and then knitting the second leg 21 on to the body and gusset. The circular closure may be a turned welt either closed by relative twisting of the plies or by binding a yarn round between the plies. The tights are knitted on a machine with a pneumatic take down and a dial with welt hooks 7. If the tights are to be knitted with closed toes, a first closure member 201 is formed and is retained by some needles after which a second closure 207 is formed similarly and is held on the welt hooks. The first leg 13 is then knitted with closure 201 as its toe and attached to closure 207 which forms the gusset. The body portion ends in a turned welt to receive a length of elastic or can be formed using an elastic yarn. Preferably the gusset closure is formed by two successive equal lengths of fabric one formed from the same yarn as the rest of the garment and one formed from cotton or like yarn so that the junction comes at the closure and the inside of the gusset is of cotton and preferably remains white during dyeing.

Title: Sintered metal objects and the manufacture thereof
IPC: B22F3/26
Filed: 1956-12-13
Abstract: Sintered metal articles (e.g. steel or bronze) are coated by being brought into contact with a melt of easily fusible metal (Pb, Sn, Zn( Sb, Cd, Bi, or mixtures or alloys thereof such as Wood's metal) which closes the pores, freed of surplus fusible metal (as by centrifuging) to leave a layer preferably of the order of 0.015 mm. in thickness, whereupon an electro-desposition e.g. of Ni and/or Cr is made directly on said layer.  The sintered body may be dipped into flux and then into the melt, or coated with a mixture of flux and powdered fusible metal with or without glycerine and heated until the said metal melts; after cooling the surface may be cleaned with fine emery or the like and then directly bright nickelled.  Pickling is not necessary if treatment with the melt occurs shortly after sintering, whilst the easily fusible metal should preferably be one melting below 425 DEG C.  Four Examples showing the details of this process are included in the Specification.

Title: Digital data store arrangements
IPC: H03K19/007
Filed: 1972-08-16
Abstract: 1357862 Dynamic binary store SIEMENS AG 16 Aug 1972 [30 Aug 1971] 38299/72 Heading H3T The invention relates to a fail-safe binary store in which 0 and 1 signals are respectively represented at input and output by opposite phases of a square wave signal. According to the invention the store comprises a master-slave bi-stable circuit MA, SL fed at its clock inputs, from terminal B, with opposite phase double frequency pulses and controlled by a majority logic circuit M, E receiving two input signals El, E2 and a feedback signal E3. As described the logic circuit is an inverting transistor circuit (Fig. 3, not shown). When both inputs E1 and E2 are in phase they control the logic output and cause the final output to follow, in phase. When E1 and E2 are out of phase the logic circuit is effectively controlled by the feedback and the output continues in the same phase as previously. A failure indicator may detect a non-alternating state of the output. Further, two stores may be operated in parallel (Fig. 4, not shown) with signals in opposite phase; an exlusive OR circuit (U) detecting a failure causing in-phase outputs. When integrated construction is used, separate clock lines improve failure detection and two opposite phase clock lines may be used, one including an inverter so that if the clock on both lines fails the two outputs are in phase and failure is detected by the "exclusive OR" circuit.

Abstract: 1,008,552. Reciprocating pumps and motors. GEORGE ANGUS & CO. Ltd. Nov. 2, 1961 [Nov. 9, 1960], No. 38553/60. Heading F1A. In a reversible, radial cylinder pump or motor with a revolving, multi-cylinder block 3 having a transverse ported face 13 slidably engaging a stationary valve plate 15 having passages 17, 18 therethrough, each valve plate passage is provided with a wall surface 17a, 18a facing axially away from the cylinder block such that liquid pressure within the passage acts to thrust the valve plate against the cylinder block, the passages and wall surfaces being of arcuate shape and subtending to the rotary axis an angle of nearly, but less than, 180 degrees. The valve plate is located for limited axial movement relative to housing 2 by dowels. Communication between the valve plate passages 17, 18 and passages 19, 20 in housing 2 is effected by sleeves 21 of arcuate shape, e.g. of nylon, slidable within the passages and provided with sealing rings 22. Surfaces 17a, 18a are arranged such that the thrust forces are symmetrically distributed. The eccentricity of the piston-engaging track 9 is adjustable relative to the axis of rotation of the block.

Title: Improvements in or relating to hydrostatic transmissions
IPC: B60K17/10
Filed: 1965-09-09
Abstract: 1,118,443. Controlling hydrostatic transmissions. T. BUDZICH. 9 Sept., 1965 [14 Sept., 1964], No. 38622/65. Heading F2D. [Also in Divisions F1 and G3] In an auxiliary hydrostatic transmission for driving at least one of the steerable road wheels 17 of a vehicle, e.g. a tractor, having a mechanical transmission between the engine and the driving wheels comprising a variable displacement pump 24 driven by the engine and a variable displacement motor or motors 19, the pump is arranged to supply fluid to the motors at a substantially constant pressure and the motors are constructed to exert a constant torque on the wheels 17 until the maximum output of the pump is reached, after which increase in speed of the wheels results in a decrease in motor torque. The motors 19 are connected to the wheels 17 through gear reducers. The pump cam plate 34 is biased to maximum stroke by a spring 45, engaging an abutment piston 43 subjected to the pressure from a gear pump 73a, and opposed by a spring biased piston 46 subjected to a control pressure in the cylinder 47. The control pressure is determined by a spool valve 59, subjected to the output pressure of the pump 24 in cylinder 61, which connects cylinder 47 to the cylinder 61 or to the pump housing 29 via passage 73. Cam plate 34 may be moved selectively to the zero stroke position by operating a solenoid 83 to cause the valve spool 82 to connect the cylinder 44 to the gear pump reservoir 78. In one embodiment of an axial piston hydraulic motor (19), Fig. 3 (not shown), the motor cam plate (97) is biased to the zero stroke position by a spring (106), with a cam plate stop (100) engaging the casing (102), and to the maximum stroke position by a piston (113) subjected to the pressure in the motor inlet port (91 or 92). The constant pressure provided at the inlet port causes the cam plate to assume maximum inclination until the demand of the motor rises above the capacity of the pump 24. The motors 19 are connected to the pump 24 through a reversing valve 50a operable by a solenoid 57 to reverse the direction of rotation of the motors. In a second embodiment of an axial piston hydraulic motor (19), Fig. 4 (not shown), the motor cam plate (136) is biased to the zero stroke position by a spring (145), which is mounted to exert a force on the cam plate when inclined on either side of the zero stroke position, and to maximum stroke on either side of zero by a piston (159) subjected to pressure. A spool valve (168) operated by a solenoid (180) pauses the two faces of the piston (159) to be connected to the high pressure motor port (130) or one face to be connected to the highpressure port and the other to the low pressure port (131). The spool valve therefore provides for reversal of the direction of motor rotation. The motors 19 may be of the vane type in which the eccentricity of the stator is varied, the stator being biased to the neutral position by a spring and to maximum eccentricity by means responsive to the pressure at the motor inlet port.
