Patent GB-131843-A (GB)
IPC: C03B9/14
Abstract: 131,843. Mathy, M. March 17, 1919. Blowing; tempering.-The charge is placed in a cylindrical mould M, a cover T is applied, and the bottom B is raised so as to bring the charge to the top of the mould. A plunger 15 carried on a bracket 5 is swung over the mould and brought down by a hand-lever 16 so as to form the initial blow opening. The plunger 15 is then removed and a blowing head 26 brought into place to blow the bottle. The head 26, Fig. 5, is carried by a loose double valve 27. When the head is raised, the valve 29 prevents the escape of air. When the head is pressed down on the mould top T, the valve 30 closes and the valve 29 opens and allows the blowing air to pass down through ports P. The mould bottom B is raised by the action of a hand-operated plunger 13, which forces oil into a cylinder 10 and so raises a piston 9, the rod 8 of which carries the mould bottom B. An electro-motor 34 drives a gear 33, feathered on the rod 8, and so rotates the bottom B, which has projections to engage and turn the blank during blowing. The plunger 15 is heated when idle by a burner 36. The mould is cooled by air circulating through a space 35. This is stated to temper the bottle.

Abstract: 744,149. Boots &c. RO-SEARCH, Inc. May 12, 1953 [May 13, 1952; June 24, 1952], No. 13224/53. Class 17 (2). [Also in Group V] In making footwear having a rubber sole moulded and vulcanized to the upper, a welt 3 is attached to the lower margin of the upper and to a tread sole 6, and the assembly is placed loosely on a metal mould last 1, together with a suitably sized rubber mix 7. A wedge-shaped divided collar 8 is then forced into the crease between the upper and the welt, thus shaping the upper and shoe bottom into conformity with the last. The assembly is then heated to mould and vulcanize the mix 7 which is bonded to the shoe crease and to the inside of the welt, thus stabilizing the shoe bottom. If it is desired to present an exposed rubber edge to the sole, a bottom plate is provided to the mould and the collar is modified to allow the insertion of a rubber strip under the welt, which, during vulcanization flows to cover its edge. In making a platform-soled shoe, Fig. 4, no welt strip is provided, the margin of the upper 2 being extended instead, so that, after a crease has been formed by the collar 22, the upper turns outwards and then at 17 covers the edge of the rubber mix for sole 16, a side plate 18 and bottom plate 21 holding it in position during vulcanization of the sole 16.

Title: Improvements in colour television voltage control system
IPC: H04N9/26
Filed: 1952-05-26
Abstract: 732,238. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. May 26, 1952 [May 24, 1951], No. 13311/52. Drawings to Specification. Class 39 (1). [Also in Group XL (b)] In a colour television cathode-ray tube comprising a screen bearing one colour phosphor and a grating in front of the screen made up of electrically separate elements bearing further colour phosphors, a set of equal and opposite voltage pulses are applied simultaneously to the elements of the grating, voltages on adjacent elements being of opposite polarity, and then a corresponding second set of voltage pulses of opposite polarities to those of the first set are applied to the elements of the grating. The electron beam is thus selectively deflected to elements of the grating while at the same time preventing stray electrons from falling on other elements of the grating and so avoiding colour contamination. Simultaneously to prevent stray electrons falling on the screen, the accelerating voltage of the tube may be reduced. When the electron beam is to excite the screen a negative voltage pulse is applied to the grating and a positive voltage pulse to the screen. Suitable circuits for feeding the voltage pulses to the tube are described (see Group XL (b)). Specification 721,199 is referred to.

Title: Improvements in, or relating to, resilient suspension mechanisms in which bush-shaped resilient units are used as springing elements
IPC: B62K25/04
Filed: 1947-05-17
Abstract: 641,656. Cycle wheel spring suspensions. BEZET, B. May 17, 1947, No. 13315. [Class 136 iii)] [Also in Groups XXXII and XXXIII] In a resilient suspension mechanism in which a resiliently oscillating crank assembly has bush shaped resilient units acting as the sole springing and pivoting elements, each unit is provided with one or more thrust mechanisms preventing resilient lateral and transversely-angular displacements of the resiliently pivoted crank assembly. As shown, the bevelled ends of a tubular spindle wheel axle 1 are fitted into wedge-shaped recesses in heads L on suspension crank links 2, 3 and a spindle 18 is passed through the axle 1 to secure it to the links by means of nuts 16. Each resilient unit 15, 17 consists of a resilient bush R to the cylindrical surfaces of which are bonded an inner pivot shaft 4 or 5 and an outer ring 6. The units 15 and 17 are fitted into lug clamps 10 and 11 in the ends of the fork blades 30 and 31 respectively, the outer ring 6 being non-rotatably attached to the forks by tightening nuts 14 and bolts 12 on the lug clamps. The threaded ends of the pivot shafts 4 and 5 are screwed into holes J and Z in the crank link heads. The height of the suspension can be altered by slackening the nuts 14 and turning the outer rings 6 to the required angle. The thrust mechanism prevents displacement of the suspension crank links in the directions indicated by the arrows 102, 103 and 104. The thrust mechanism is fitted inside the outer ring 6 and comprises a thrusting plate 9 non-rotatably coupled with the outer ring 6 by means of cogs and a thrust plate 7 non-rotatably fixed to the crank link 2 or 3. A friction plate 8 is interposed between the plates 7 and 9 to prevent seizing. Alternatively, as in Fig. 3 the interlocking of the crank link heads 2 and 3 with the axle 1 and pivot shafts 4 and 5 may be carried out by cone coupling. A circlip 34 may be used for non-rotatably mounting the outer ring 6 in the lug 11 of the fork blade end 31. In an alternative method of mounting the resilient unit, shown on the right-hand side of Fig. 3, the bush R is bonded direct to the lug 10 which is fitted on the end 30 of the fork blade. Specification 579,861 is referred to.

Title: Improvements in television transmitters
IPC: H04N7/169
Filed: 1949-05-23
Abstract: 670,442. Television transmitter. ZENITH RADIO CORPORATION. May 23, 1949 [July 2, 1948], No. 13691/49. Class 40 (iii). A television transmitter for use in a system such as is described in Specification 647,892, wherein the programme radiated is available for reception by privileged persons only comprises means for generating television picture signals and a coding signal which are radiated from the transmitter, and a key signal which is sent by a line transmission channel to the privileged persons, the television picture signal being coded by the coding signal which is itself modified in accordance with the key signal so that at each co-operating receiver both the coding signal and key signal are needed for effecting decoding of the received television signal. The co-operating receiver may be as described in Specification 670,443. Picture signals are generated in the camera unit 1 and are passed by a channel comprising units 6, 7, 8 and 9 to an aerial 10 whence they are radiated as modulations of a radio-frequency carrier wave. Synchronizing signals are generated in circuit 11 and are mixed with the picture signals in circuit 7, and are also applied to frame-scanning generator 14 and line-scanning generator 15 to control the scanning in the camera unit 1. The line synchronizing pulses are applied to the generator 15 via a pulsephase modulator 16 to which coding signals are also applied so that the timing of the line scans in the camera unit with respect to the linesynchronizing pulses applied to the circuit 7 is varied in accordance with the coding signals. The coding signals which are generated in circuit 20 are radiated from aerial 28 as modulations of the sound carrier wave and are also applied to pulse-phase modulator 16 through unit 21 wherein they are periodically inverted in sign under the control of a key signal generated by circuit 18. This key signal, which comprises periodic bursts of oscillations triggered by pulses from a frequency divider 17 which is itself supplied with frame synchronizing pulses from unit 11 is applied at terminals 19 to telephone lines in communication with the co-operating receivers and is also applied to circuit 22 to which are also applied framesynchronizing pulses from unit 11, the circuit 22 acting to switch circuit 21 to its modified condition, wherein signals passing through it .are inverted when the first vertical synchronizing pulse following the commencement of the key signal is applied thereto and to restore its original condition when the vertical synchronizing pulse immediately following the terminaation of key signal is applied thereto. Specification 668,465, [Group XXXVI], also is referred to.
Patent GB-1190674-A (GB)
Title: Improvements relating to Secondary Radar Systems.
Inventor: WOOLLVIN GEOFFREY GEORGE
IPC: G01S13/76
Filed: 1968-03-21
Abstract: 1,190,674. Transponders. A. C. COSSOR Ltd. 21 Feb., 1969 [21 March, 1968], No. 13747/68. Heading H4L. A secondary radar transponder comprises means responsive to the first pulse of a received group to generate a comparison group of pulses having the width and spacings corresponding to a given mode, means for comparing the received groups with the comparison group to generate error pulses where the two groups are not in register, means for integrating the error pulses and threshold means operative when the integrated pulses exceed a predetermined level to reject the interrogation signal. As described, the transponder is designed to handle the type of code in which four pulses spaced at 2 Ás. intervals are followed by a side lobe suppression pulse. General arrangement, Fig. 1.-The incoming signal is supplied via terminal A to a unit 10 which passes only pulses having the requisite widths and amplitudes specified for the signal and the resulting output is fed to a circuit 14 which suppresses the operation of various circuits when a pulse group has been recognised correctly. Normally pulses from line C are passed via line D to pulse group recognition circuitry 16 which tests whether the pulses have the correct spacings and if so a pulse is passed to a trigger terminal F to prepare a computer to respond to the interrogation signal supplied from circuit 14 to terminal E. The inverse of the signal on terminal F is supplied via line G so that when a pulse group is not recognized the circuit 14 starts a counter 24 which runs for a predetermined suppression interval and then supplies a signal to circuit 14 to terminate the suppression. Group recognition circuit, Fig. 2.-The output of a 16 mHz. oscillator 98 is supplied to a chain of bi-stable frequency dividers 100 to 106 and the combined output of bi-stables 103, 104, which form the comparison group of pulses, together with the interrogation signal on line D are supplied to a gate 110. The output of gate 110 consists of narrow pulses where the two pulse groups do not match and these pulses are integrated at 112 and supplied to a bi-stable 114. The bi-stable 114 is preset by the first pulse on line D and this removes a presetting input to bi-stables 100 to 106. If the output of integrator 112 is sufficient to overcome the threshold of bi-stable 114 the bi-stable is cleared and the presetting input on bi-stables 100 to 106 reimposed. Bi-stables 105, 106 supply signals to a gate 116 when four pulses have been produced by bi-stable 104 signifying that an interrogation can be accepted, the fourth pulse being supplied via a NAND gate 116 to a line G to initiate triggering. The rising trailing edge of the output of gate 116 clears the bi-stable 114. The output of gate 116 is also inverted at 118 and supplied to terminal F.
