Abstract: 188,905. Walker, F. E., and Hill, C. H. Oct. 20, 1921. No Patent granted (Sealing fee not paid). Presses; moulds.- Relates to concrete block &c. presses of the type in which a screw-operated pressure plate co-operates with a bottomless mould, and comprises a mould movably disposed in guides within a container, means being provided for raising the container clear of the mould or simultaneously with the mould clear of the moulded blocks. Figs. 1 and 4 show a portable press comprising a framework supported on wheels u running on rails v, the framework carrying uprights a supporting an entablature b furnished with bushes c through which work screws d connected to a pressure plate k furnished with lugs m engaging guide grooves in the uprights a. Movement is imparted to the screws d through gearing f, e, by a hand-wheel h. The moulds, which may be built up of loose plates, are disposed within an open-bottomed container q having lugs q<1> engaging guide grooves in the uprights a, the mould sides having lugs r adapted to enter guide grooves in the container. For raising the container, pins are passed through interengaging lugs w, x respectively on the container and pressure plate k whereby the container can be raised by operating the screws d. Pins z are passed through holes in the sides of the container and the lugs r to connect the mould thereto so that it may be raised simultaneously therewith. In use, a loose bottom plate is placed between the rails v and the press is brought into position thereover, after which the mould and container are lowered on to the bottom, the pressure plate k is disconnected and raised, and the mould is charged with material. Pressure is then applied through the plate k after which the mould, container and pressure plate, are connected together and raised clear of the moulded blocks and the press removed, leaving the blocks upon the bottom plate to set. In a modification, a stationary press is employed, the mould bottom 3, Fig. 5, being supported upon a travelling bogie 1. The bottom 3 is supported by springs 2 adapted normally to raise the bottom above side members 4 which support the bottom during pressing.

IPC: H04N1/415
Filed: 1974-06-25
Abstract: 1457039 Data transmission; facsimile systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd and MATSUSHITA GRAPHIC COMMUNICATION SYSTEMS Inc 25 June 1974 [25 June 1973] 28040/74 Heading H4P In a facsimile system, bits representative of black/white picture areas of each complete and successive line scan, e.g. 2048 bits, are subdivided into groups of say 16 bits, each group being compared with a corresponding group of a previous scan (i.e. 128 comparisons) which correspond with an equal number of stored codes. A circuit also detects and provides a 00 code when a group of 16 bits represents an "all white" area; 128 bits of code signals are stored in a register and read out for transmission then recirculated for later use. A further line "all white" detector i.e. 2048-0's disables the coder and substitutes 8 x 1's. The 2048-0's are then stored for used as the next comparison line. With start switch 22 closed, a facsimile reader applies bits to register 51 and ring counter 32 energizes gate circuit 34 to provide connection between comparator/detector 19 and code register 61; stepping pulses are applied to register 51, also 54 which recirculates a previous line. If there is no previous line a series of 0's is entered Comparator/detector 19 comprises a coincidence circuit 91 (see Fig. 4, not shown) having 16 bit registers (92, 93) coupled to exclusive OR's (94-1 to 94-16) (only two shown) which deliver 0's to inverters (95) and hence 1's to AND (96) on coincidence between the reference signal from register 54, through line (90) and incoming video signal on line (18); the latter is also applied to flip-flop (97) hence if the input on (18)=1, (97) gives 1 on line X. Correspondence between inputs on (18, 19) will give a 1 on line Y, hence under operating conditions X, Y may present 11, 10 or 00, the latter being transmitted as 0. Comparison is repeated 128 times to generate a sequence of 128 code signals which are entered into register 61. When this is filled, flip-flop 81 functions to detect an all 0's situation. On non-correspondence the actual group is transmitted. The next clock pulse causes associated ring counters in the arrangement to advance one position hence selecting the register 52, 62 and flip-flop 82 for reception of next line bits and the reference register is shifted from 54 to 51, the bits in which are recirculated while 52 is entered by bits corresponding to the next line. An all 0's situation causes transmission of 8 Î 1's to be transmitted via modulator 102 while flip-flop 81 is reset. Since code signals are transmitted as one or two bits (the latter at half clock rate) loss of any signal will disrupt decoding, hence check bits may be inserted in transmitted sequences. The receiver operates approximately inversely to that of the transmitter. A separator (202) is incorporated for sync. pulses which are passed to ring counters (204-207) which distribute their outputs to appropriate circuits and to a register control circuit (208) which produces an enabling pulse to decoder (215) and counter (210).

Abstract: 1,184,458. Non-reactive couplings. CURTISS-WRIGHT CORP. 19 June, 1967 [22 June, 1966], No. 28129/67. Heading F2E. A non-reactive coupling comprises an input shaft 10, an output shaft 12, a helical spring (44 or 46) secured at one end for rotation with the output shaft and having an interference fit with a fixed structure 30 so as to lock the output shaft against rotation in one direction, an arm 59 pivotally mounted on the output shaft 12 and arranged to be deflected upon movement of the input shaft 10 in one direction thereby causing the arm 59 to engage the free end of the spring to unlock the output shaft 12 from the fixed structure 30 so that rotation of the input shaft 10 can be transmitted to the output shaft, the arm 59 being arranged so that any movement of the input shaft 10 is amplified at the free end of the spring 44 or 46. As described, the input shaft 10 is piloted in the tubular output shaft 12, the latter being splined to collars 18, 20 rotatable in bearings 26, 28. The outer ends of the springs 44, 46 are secured by grub screws 48, 50 to the output shaft 12. The arm 59 is terminated in a ball 60 which is pivoted in a socket 62 in the output shaft 12 and extends into an arcuate slot 64 in the input shaft 10. The arm 58 is deflectable by the bifurcated ends 65, 66 of a pin 68 in the input shaft 10 so that rotation of the input shaft 10 in either direction causes an amplified movement of end 56 of arm 58 so as to engage a tang 52 or 54 at the free end of spring 44 or 46 which disengages that spring from the fixed structure 30 and thus permit a pin 70 to engage the end of an elongated slot 76 in the output shaft and allow the rotation of the input shaft 10 to be transmitted to the output shaft 12.

Filed: 1947-10-22
Abstract: 637,266. Resilient mountings. GENERAL TIRE & RUBBER CO. Oct. 22, 1947, No. 28285. Convention date, Feb. 27. [Class 108 (iii)] In a vibration-absorbing resilient mounting comprising two relatively movable members having rigid bearing surfaces, an annulus of resilient material having a non-circular cross-section and one sectional axis substantially greater than the other and disposed between the bearing surfaces to prevent contact therebetween, the major sectional axis of the annulus and bearing surfaces being dimensioned so that the annulus bears against annular portions of the bearing surfaces, whereby, on relative movement of the annulus and bearing surfaces towards each other, the major axis is first partially tilted or rotated about its own centre to a more acute angle so as to be substantially parallel therewith, after which the resilient member is compressed between the bearing surfaces. In the arrangement shown, an annulus 5 of resilient material of non-circular (preferably elliptical) crosssection, is disposed between substantially parallel frusto-conical bearing surfaces 2 and 4, such that under normal loading, the major axis 8 of the annulus 5 lies at an angle of between 20 and 60 degrees to the surfaces 2 and 4. Preferably, annular, seats 11 and 12 are provided on the surfaces 2 and 4 respectively, to prevent slipping of the annulus 5 whilst permitting free rolling action of the latter during initial relative movement of the surfaces 2 and 4. In a modification (Figs. 4 and 5, not shown), the annulus is disposed between and with its major axis at an acute angle to, coaxial cylindrical bearing surfaces, each of which is provided with a seating for the annulus. In another modification (Fig. 6, not shown), adhesive film such as heat-softenable resin-base composition, or rubber to metal adhesive, is disposed between the annulus 5, Fig. 2, and one or preferably both bearing seats 11 and 12, prior to assembly. After assembly the parts may be adhered together by heating the mounting. Alternatively, any suitable means may be employed for obtaining adhesion between the annulus and the seats. The annulus 5 is preferably moulded flat, so that the major axis 8 of each and every section lies in a single plane.

Abstract: 946,373. Piston packings; joint-making packings. BAROGENICS Inc. July 25, 1962 [July 28, 1961], No. 28620/62. Headings F2B and F2T. A sealing ring assembly comprises a radially expandible carrier ring 16, Fig. 3, or 25, Fig. 6, with coaxial sealing rings 19, 20 or 27, 28 engaging respectively with one of the axially facing side faces of the carrier ring and with either the outer peripheral surface, Fig. 3, or the other side face, Fig. 6, of the carrier ring, at least one of the sealing rings having an unexpanded outer diameter which is less than that of the carrier ring. In Fig. 3, the sealing rings 19, 20 which may be made of neoprene or steel tubing, are located in annular grooves 17, 18 formed at the junction of the side faces of the carrier ring and its inner and outer peripheral surfaces. Alternatively, one or both of the grooves may be U-shaped in cross-section and formed in the outer peripheral surface and/or one side face of the carrier ring. The sealing assembly is mounted between a cylinder 11 and a reciprocating piston 10 and is retained axially in a groove 14 in the piston by a cover-plate 12. In operation, the piston actuating pressure fluid m enterthe space i exerts a radial force on the carrier ring 16 greater than that exerted by pressure P 6  resulting from the deformation of the ring 19 so that the carrier ring is expanded against the cylinder wall thereby preventing extrusion of the ring 19 through the working gap g. Also, the downward force due to fluid pressure on the ring 16 is greater than the upward force due to fluid pressure and deformation of ring 20 so that the lower face of the ring 16 abuts against the piston and prevents extrusion of the ring 20. In Fig. 6, the sealing rings 27, 28 are located between the inwardly tapering web portion 26 of the carrier ring 25 and the opposite faces of an annular groove 24 formed by notches machined into the inner peripheries of abutting surfaces of flanges 21, 22 of a pressure vessel. The rings 27, 28 are retained in position by a small tip machined at the inner periphery of the web portion or by a separate retainer ring snap-fitted thereover. As shown, when pressure fluid is introduced in the vessel the flanges become separated from each other by a gap 28a which is sealed by the rim of the carrier ring 25 which also prevents extrusion of the expanded rings 27, 28. In Fig. 7, sealing rings 40, 41 are mounted in grooves in a carrier ring 32 and the assembly is located in a groove 31 in one of two abutting flanges 29, 30 of a pressure vessel. The ring 32 is greater in height than the depth of the groove 31 and is forced by pressure fluid radially against the flange 30 and upwardly against the flange 29. The sealing rings in the above embodiments may be of square, O, V, delta or crescent-shape in cross-section.
