Title: System for generating single sideband phase modulated telegraphic signals
IPC: H04L27/20
Filed: 1964-06-17
Abstract: 1,072,581. Data transmission; phase shifting circuits; twinplex and like systems. KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA. June 17, 1964 [June 17, 1963], No. 25129/64. Headings H3W, H4L and H4P] A single side-band phase modulated signal generator is characterized by shifting the phase in one direction only to indicate change in the modulating data. A twinplex type system using n synchronized binary data inputs is described. In a single-input embodiment, Fig. 2 (not shown), binary data (at 1) is fed to a balanced modulator (4) and to a unit (8) which produces transition pulses which are fed to a second modulator (6). The modulators are fed by a carrier oscillator (3), and their outputs-that of the balanced modulator (4) being shifted 90 degrees-are added (at 7), the resultant signal being a single side-band signal with its phase changing in one direction only, and by 180 degrees per bit change. Twinplex-type systems for two and three input channels are described. In a twochannel system, Fig. 9 (not shown), a unit (III) derives from the two binary inputs (1a, 1b) an output having 2<SP>2</SP>=4 states which, via a logic arrangement, selectively controls modulators (14-17) which are fed with carrier having phase shifts of 0 degrees, - #/2, # and #/2. A phase shifter, Fig. 18A, comprises a bandpass filter 88. A sinusoidal wave at 70 is frequency changed at 87 by way of a V.F.O. 90 controlled by a signal at 72b. The delay introduced by the filter depends upon the frequency fed to it. The filter output is reconverted to the original frequency by mixer 89.

Title: Plunger valve
IPC: F15B13/043
Filed: 1954-09-01
Abstract: 757,853. Valves. COLLINS, J. E. Sept. 1, 1954 [March 11, 1954], No. 25408/54. Class 135. A plunger valve mechanism has a bored body capped at 21, 22 at each end and with ports leading into the bore, packing members 30 to 34 mounted in the bore between the ports by retainers 26 to 29, and a plunger 25 sealingly slidable in the packing members under the action of a piston 77 connected to one end of the plunger and slidable in a pressure chamber 46 at the end of the bore whereby pressure fluid maintained in the chamber biases the plunger towards that end. Pressure fluid is supplied at 39, Fig. 3, and passes at 38b to the chamber, at 38c, Fig. 4, to an annular groove 65 in the base of a solenoid valve B, Fig. 1, via passage 61 and valve 60, passages 62, 67 and through the open valve 70 of the unenergized solenoid valve, and via groove 53a and passages 71, 72 to the chamber 47 where it moves the plunger valve to the left. The pressure at 39 now passes through passage 38a, retainer port 26a, around plunger valve neck 25a, through retainer ports 27a to a motor port 43. Another motor port 44 is then connected via retainer ports 29a, neck portion 25b, and retainer ports 28a to an exhaust passage 45. When the solenoid is energized valve 70 is closed and valve 74 opened so that pressure in chamber 47 is exhausted via passages 72, 71, valve 74 and passage 76 leading via ported retainer 28 to the exhaust 45. With the solenoid unenergized, the plunger valve may be controlled manually by the valve 60 which, when opened allows pressure from 61 to pass to the chamber 47, and when closed allows pressure in 47 to be exhausted via a stem passage 59. The plunger valve 25 is meant to be oscillated rapidly by intermittent energization of the solenoids. The caps 21, 22 contain pads 23, 24 for eliminating shocks in the valve and cap 21 contains a sintered bronze venting filter 83. Specification 726,379 is referred to.

Title: Improvements in or relating to fishing reels
IPC: A01K89/015
Filed: 1952-10-14
Abstract: 721,724. Fishing reels. AKTIEBOLAGET URFABRIKEN. Oct. 14, 1952 [Oct. 15, 1951], No. 25768/52. Class 48. A mechanism for disconnecting a clutch connecting the spool and the driving mechanism of a fishing reel and for retaining the clutch in released position comprises a manually operable lever 1 for actuating the clutch and two swing- able locking arms 18, 19 arranged so that at least one of them retains the lever 1 in clutch releasing position on actuation of the lever 1 at any position of the handle 5 of the driving mechanism, the locking arms being actuated by operation of the driving mechanism to permit re-engagement of the clutch. When the lever 1 is pushed radially into the reel casing it displaces towards the right a spring-returned pivoted arm 10 which in turn carries a clutch element 9 out of engagement with a co-operating clutch element 8 thus disconnecting a gear 4 from the shaft 7 of the spool. The locking arms 18, 19 are pivoted on pins 20, 21 disposed on either side of the shaft 24 of the handle and are urged by springs 22, 23 to abut studs 16, 17 on the lever 1 and fixed studs 20a, 21a on the casing. The studs 16, 17 on the lever 1 are arranged in relation to the locking arms so that when the lever is held in its fully inward position by the stud 16 engaging the locking arm 18 the other stud 17 is spaced from the other locking arm 19 (see Fig. 2). The arms are rocked alternately on rotating the handle 5 by a pin 26 on a disc 25 on the shaft 24 of the handle engaging cam faces on the arms. Thus the pin 26 engages and swings the arm 18 as the handle is rotated from the position shown in Fig. 2 to the position shown in Fig. 3 so that the arm 18 allows the lever 1 to be moved downwardly by a spring 12 until the arm is arrested by the stud 17 abutting the other arm 19. Further rotation of the handle causes the pin to engage and swing the arm 19 so that the lever 1 moves down farther to the position corresponding to the clutch being engaged. The arm 18 is so shaped that it is prevented by the stud 16 from returning to its locking position when the pin 26 disengages from its cam surface; and when the lever is in the clutch engaging position the studs 16, 17 prevent the locking arms from returning to abut the stops 20a, 21a. In a modified construction both locking arms are journalled on a common pivot pin and the lever 1 has only one stud.with which both arms engage. In another modification, Fig. 8, one 31 of the studs on the lever 1 is vertically slidable in an elongated slot in the lever and is normally held at the bottom of the slot by a spring 32. Alternatively the pivot pin of the locking arm 18 extends through an elongated slot in the arm so that the arm can move vertically and a spring acts between the pivot pin and the arm to hold the pin normally at the bottom of the slot.
