Title: Improvements in and relating to the construction of crank shafts
IPC: F16C3/10
Filed: 1922-09-26
Abstract: 208,778. Morison, D. B. Sept. 26, 1922. Crank-shafts; securing cranks on shafts.- In built-up crank-shafts for marine engines, internal - combustion engines, &c., the flanks A of the crank web or webs remote from the journals are solidly united, as by electric welding, with the crank pin or the shaft or both, preferably in such manner as to render the joint equal in strength to the component part of the crank-shaft. The remaining width of the web may be shrunk on to the pin and shaft. The weld may be effected by running fused metal into an annular channel, or it may be in the form of a series of plugs or strips. The Provisional Specification describes the pin or shaft as having an extension united to a ring-shaped projection on the web flank, the main bearings being designed to clear such projections; where keys are used as additional securing-means, their ends merge into the integral joint.

Title: Improvements in and relating to methods of stabilizing methyl-substituted polysiloxanes
Filed: 1947-09-25
Abstract: Liquid dimethyl siloxanes are stabilized against gelation at elevated temperatures (e.g. 200 DEG  C.) by addition of a small amount, e.g. 0.05-5 per cent by weight of ketene.  Treatment with ketene may be followed by distillation to remove materials boiling below 150 DEG C.  Preferably ketene gas is bubbled through the liquid siloxane for 30 minutes to 6 or more hours.  Polymers of ketene, e.g. diketene or dihydroacetic acid may be used, but are not so effective as ketene itself.  Specification 586,188 is referred to.

Title: Improvements in impulsing arrangements particularly applicable to automatic telephone systems
IPC: H04Q1/36
Filed: 1933-09-21
Abstract: 428,856. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Sept. 21, 1933, No. 26133. Convention date, Oct. 4, 1932. [Class 40 (iv)] In an arrangement in which impulses from dial springs 12 are repeated by relays R3, R4 connected in parallel and having separate batteries B3, B4, differences in battery potential and in circuit resistance give rise to irregular operation of the relays, which is prevented by rectifiers L1, L2. For example, when the circuits are opened, the more strongly energized relay would, in the absence of rectifiers, cause a reverse current through the other which makes the first release slowly and the other quickly.
Patent GB-1210650-A (GB)
Title: Apparatus for encoding binary data
IPC: H04L25/49
Filed: 1969-05-22
Abstract: 1,210,650. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 22 May, 1969 [31 May, 1968], No. 26154/69. Heading G4C. In encoding apparatus, binary input data is shifted into a shift register, a first output signal channel 90 being provided for signalling the presence of a 1 in a first of two consecutive stages 81, 82 of the register, and a second output signal channel 92 being provided for signalling the presence of a 0 in both the two consecutive stages, each signal from the second channel setting a latch to block the second signal channel from passing a signal in the next bit interval. An oscillator 83 produces two cycles of square wave per bit interval to cause a trigger 84 to produce a pulse at A, B, C, D during the first quarter, the last half, the first half and the third quarter of each bit interval respectively, and to cause a single shot 85 to produce a short pulse at the beginning and centre of each bit interval. AND 90 produces a pulse at the centre of each bit interval corresponding to a 1. AND 92 produces a pulse at the beginning of each bit interval corresponding to a 0 except when the previous bit interval contained a pulse (at centre or beginning). The exception is achieved for a previous centre pulse (bit 1) by the upper input to AND 92, and for a previous beginning pulse (bit 0) since each pulse from AND 92 sets a latch 109, causing a latch 105 to be set at the centre of the bit interval which causes latch 109 to be reset at the start of the next bit interval which causes latch 105 to be reset at the middle of the latter bit interval. The set state of latch 105 inhibits AND 92. Each pulse from AND 90 or 92 causes a transition at 117, for recording on a record medium, or transmission.

Patent GB-442897-A (GB)
Title: Improvements in or relating to the tuning of thermionic valve circuits
IPC: H03J7/16
Filed: 1934-09-14
Abstract: 442,897. Wireless receiving-apparatus. COLE, Ltd., E. K., Priory Crescent, Southendon-Sea, and BRADFIELD, G., 161, Hainault Avenue, Westcliff-on-Sea. Sept. 14, 1934, No. 26366. [Class 40 (v)] A manually tuned radio - receiver has automatic means for finally adjusting the tuning exactly to the desired signal comprising a variable tuning member to vary the resonant frequency of the receiver circuits through the desired frequency in one sense, movement of the tuning member being arrested on reaching the desired frequency on the reverse travel. Part of the output from an intermediate frequency amplifier V0 of a superheterodyne receiver is applied to a diode X (the signal rectifier and subsequent stages are not shown) having a load resistance R, the negative end of which may be connected by a switch S1, S2 either to the grid of valve V1, through a unilateral conductor W, or to valve V2. The common anode circuits of V1, V2 include the operating coil BM of a magnetic brake associated with a tuning member which is varied to sweep in both directions over a frequency range, which includes the desired frequency. With switch contacts S1 closed the p.d. across R will rise to a maximum at the desired frequency, thus charging up the condenser C1, and therefore the grid of V to a given negative potential. Switches S1 and S3 are now opened, and S2 closed, the movement of the tuning member being simultaneously reversed. When the latter reaches the position of resonance the p.d. across R charges condenser C2 and the grid of V2 to the same negative potential as that of V 1. As these valves have similar characteristics, the current through BM ceases and the brake acts to prevent further movement of the tuning device. In a modification, (Fig. 2, not shown), the valve V2 is dispensed with, the voltages of condensers C1, C2 are applied alternately through a vibrating twoway contact to the grid of VI, the output of which comprises a bridge arrangement of four rectifiers, the brake relay BM being connected across one diagonal; the principle is the same. Fig. 3 shows an arrangement for imparting a step by step movement to the shaft M of a tuning device through a spur wheel A and escapement D. Closure of switch S1 in Figs. 1 and 2 energizes electromagnet P, the armature O thus rotating the ratchet wheel N in an anticlockwise direction; N is free to rotate on shaft M. Closure of S2 may break the circuit of P and the shaft M is slowly stepped round under the pull of spring H, the escapement DEF providing the slow return. This device may be employed to sweep the tuning automatically in the reverse direction, the brake magnet K, which arrests further movement of wheel A and shaft M, corresponding to BM of Figs. 1 and 2. Specification 441,691 is referred to.

Title: Improvements in the manufacture of electric devices having closed envelopes
IPC: H01J9/24
Filed: 1965-06-23
Abstract: 1,059,053. Discharge tubes; electric incandescent lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 23, 1965 [June 26, 1964], No. 26581/65. Headings HID and H1F. Electric devices having current conductors secured in a sealed envelope, e.g. discharge or incandescent lamps, are manufactured by introducing into a long tube a strand consisting of a sequence of mechanically interconnected current conductors, exhausting the tube, and closing the tube at points spaced along its length to form a series of sealed devices each of which includes at least one current conductor. Discharge tubes are formed from a strand, Fig. 1, composed of rigid conductors 2, cylindrical electrode members 3 joined by thin wire 4, and linking glass beads 5, which strand is drawn into a glass tube which is then exhausted and supplied with the desired gas filling (Fig. 3, not shown), prior to sealing the beads 5 to the tube and cutting it through at 6 to form two separate sealed tubes. The thin wires 4 are burnt out by the passage of current, and the expansion portion drawn out to provide a lead of adequate length (Fig. 4, not shown). By the use of a strand having two parallel wire portions between each pair of glass beads, lamps in which each electrode is supported at each end. the discharge path being transverse to the tube axis, may be produced (Figs. 10 and 11, not shown). In a strand employed for the mantifacture of incandescent lamps, one end of each member 3 is sealed into a glass bead, and the filament portions 4 are protected from damage, during insertion into the tube, by laying the strand in a semi-cylindrical member which, subsequent to insertion, is rotated through 180 degrees and withdrawn (Figs. 6 to 8, not shown). Lamps having two independently controllable filaments 54, Fig. 13, separated by glass fibres 57, may be manufactured by the use of a double strand. Reference is made to the use of more than two strands, and to the production of devices which are not, in the course of manufacture, separated from one another.

Title: Change-speed control
IPC: F16H61/02
Filed: 1966-06-15
Abstract: 1,091,939. Change-speed control. TWIN DISC CLUTCH CO. June 15, 1966 [July 19, 1965], No. 26649/66. Heading F2D. A gear lever is given a pivotal movement for establishing a gear ratio, is given a rotary movement about its own axis for giving forward and reverse drive, and is shifted longitudinally to determine the speed of the input shaft of the gearing either by controlling the degree of engagement of a slip clutch or by controlling the speed of a prime mover. The arrangement is particularly intended for controlling a vehicle such as a bulldozer. The transmission comprises an engine-driven shaft 18 connected by a slip clutch 11 and a hydrodynamic torque converter 12 to the input shaft 28 of a constant-mesh variable-ratio gear. Gears 30, 32 are clutchable to the input shaft 28 by a forward clutch 29 and a reverse clutch 31 and mesh a gear 34 directly and by way of a countershaft 36, respectively. Gear 34 drives countershafts 48, 54 to which gears 51 and 56, 59 are clutchable by a first ratio clutch 49, a second ratio clutch 55, and a third ratio clutch 58, respectively. Gears 45, 44 on an output shaft 15 are meshed by the gears 51, 56 and 59. Thus three forward and three reverse ratios are provided, the output speed for each ratio being variable by controlling the engagement of the slip clutch 11. All the clutches are engaged hydraulically under the control of solenoid valves, which, in the case of the ratio and forward and reverse clutches, are controlled by a switch arrangement 124 having switches mounted on a fixed plate 125 and which are operated by a magnet 121 mounted on a plate 122 which is positioned by the gear lever 71. Each ratio is controlled by two pairs of switches disposed at right-angles. For example, the third gear clutch 58 is controlled by switches 132A, 132B disposed at right-angles, and forward and reverse at this ratio by switches 132R, 132F. The lever 71 is rotatable and axially slidable within a sleeve 85 which is pivotally mounted in a housing 78 by a spherical bushing 86. A collar 144 fast with the gear lever axially slidably receives two rods 127 which are fast with the plate 122. Plate 122 is fixed axially by co-operation with a groove in a guide-rod 130 which is fixed to a collar 115 on sleeve 85. Pivotal movement of the gear lever 71 about the spherical bushing 86 to a 1, 2, 3 or neutral position defined by an aperture 75 in the housing positions the magnet 121 in the quadrant corresponding to the ratio selected, the lever being biased towards the selected position by an overcentre spring arrangement (Fig. 13, not shown). The gear lever is then rotated to align the magnet with a pair of switches which close to establish the ratio and forward or reverse. To control the clutch 11 a collar 150 is fast axially with the gear lever and rotates a potentiometer shaft 153 by way of links 151, 152. The potentiometer acts through a control box 157 to adjust a valve 25 controlling the pressure supply to the clutch.
