Title: Improvements in or relating to recording instruments
IPC: G07C1/08
Filed: 1926-11-05
Abstract: 285,114. Sutherland, W. C., and Denton, J. Nov. 5, 1926 Recording particular operations.-In an electrically-actuated recording instrument wherein a series of marking members are laterally movable over a time-controlled record-strip, the marking members are associated with means controlled by the operating electromagnets so that they are moved laterally across the record-strip and remain in set position until returned by the armatures at the end of the succeeding impulse. The record-strip is also arranged to pass over a movable support which can be displaced to free the strip from the marking members to facilitate its removal. As shown in Figs. 4 and 5, the marking members d are mounted on levers 2 pivoted at 2<a> to a crossbar 3 pivotally mounted at one end. An extension of each of the levers 2 is provided with a slotted hole g. in which works a pin 5a on an arm 5 extending from a spindle 6. To maintain the marking member in its set position after each impulse, each of the spindles 6 is provided with an arm 9<a> having a wedgeshaped end h, h<1> co-operating with a swivelling wedge-shaped member 12 frictionally pivoted on the spring-controlled armature lever 13 of an electromagnet 10<a>. The record produced is as shown at s, Fig. 4. The armature, when attracted, causes the wedge 12 to assume its central position by the extensions 12<a>, 12<b> engaging a fixed bar 15 so that on being released the wedge engages one or other face h, h' and rocks the corresponding lever 2 to its other lateral position. The marking members d may he lifted off the record-strip by raising the crossbar 3 to afford access to the record rolls, as described in Specification 275,122. The members d may remain stationary and the record-strip be relieved by pivotally mounting a part 20 of the supporting table, a. hand lever 21 being provided for holding the part 20 in its raised position.

IPC: G01K7/12
Filed: 1963-07-12
Abstract: 1, 014, 418. Automatic temperature controL DE LA RUE REFRIGISTON Ltd. June 11, 1964 [July 12, 1963], No. 27809/63. Heading G3R. The temperature of a cold junction thermocouple is automatically maintained constant by locating it in an elongated tube which is closed at its lower end and immersed in a chamber containing liquid, freezable at a temperature close to that to be maintained, which is cooled by thermoelectric means under the control of a detector sensitive to the proportion of frozen liquid. In Fig. 1, a large number of varnished thermocouple cold junctions 4 are housed in a long tube 1 of thin stainless steel having a copper end cap 2 or a similar tube 1<SP>1</SP> having a lower portion 2<SP>1</SP> of copper, silver, gold, aluminium or beryllium oxide and an upper portion 3<SP>1</SP> of thermally insulating material. The tubes, which contain heat conducting liquid such as silicone oil or mercury at their lower ends, are mounted in a chamber 6, e.g. of copper or aluminium, containing, e.g. triply distilled water, which is frozen by a Peltier device 8 the cold junctions of which are in thermal contact but electrically insulated from chamber 6, and the hot junctions make similar contact with heat sinks 9 clamped in position by a band 22 and attached to cooling fins 10. The heat sinks 9 may, alternatively, be water cooled. Chamber 6 is surrounded by a casing 12 containing foamed plastic heat insulating material. When the proportion of water frozen has a predetermined value, a beryllium copper bellows 16 operates a switch to de-energize the A.C. input to a rectifier (not shown) supplying the Peltier device which is thereafter operated intermittently to maintain the proportion of frozen water between predetermined limits. If desired, the time constant of the on-off cycle may be increased by increasing the wall thickness of chamber 6 or delaying the operation of the switch. The energization of the Peltier device may, alternatively, be reduced periodically to a value above zero. In a modification, a switch responsive to low ambient temperature changes the manner of operation so that the Peltier device is switched between cooling and heating instead of cooling and off. In this arrangement a further switch may be operated to increase the energization of the Peltier device when starting up or when ambient temperature is high. Use of a flexible diaphragm or mercury plug instead of bellows 16 is referred to. Cooling of the portions of the tubes outside chamber 6 by an auxiliary Peltier device is also referred to.

Abstract: 1,152,458. EHT generators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 June, 1966 [22 Feb., 1966], No. 28175/66. Heading H2F. [Also in Divisions H3 and H4] A circuit for producing EHT and focusing voltage for a television receiver maintains a fixed ratio between the voltages although increase in beam current only loads the EHT circuit and not the focusing circuit. The circuit shown, for a colour television receiver, includes a line deflection stage 1 coupled via transformer 6 to deflection coil 17 and includes booster diode 10 and booster capacitor 12. The defleotion current in coil 17 is stabilized -by varistor 14 and is adjustable by resistor 53 which varies the boost voltage across capacitor 12. Flyback pulses are rectified at 19 to provide a voltage Vf (adjustable at 21) which is fed to the focus electrode. Flyback pulses in winding 8 are lengthened by inductor 25 and converted by triode 27 into a sawtooth waveform which is fed to the grid of pentode 31 which provides a sawtooth current in transformer 34. Flyback pulses in secondary winding 37 are rectified at 41 to provide the EHT for the cathode-ray tube. The line deflection circuit 1 and the EHT circuit 31 are supplied by separate sources Vb, Vb<SP>1</SP>. A control valve 43 is turned on by flyback pulses across winding 44; the current in valve 43 being dependent on the voltage of source Vb<SP>1</SP> and being arranged to feed a compensating bias to pentode 31 so as to stabilize the EHT. A shunt 38 is included in the EHT circuit so that valve 43 provides compensation for changes in cathode-ray tube beam current. The grid of valve 43 is coupled to the final anode by a capacitive divider comprising capacitor 47 and the capacitance of the coaxial cable 42. A circuit 49, 50, 51 ensures that the length of the deflected lines can be adjusted by resistor 53 without change in EHT voltage.

Filed: 1953-10-14
Abstract: 734,469. Sliding clasp fasteners. RI-RI WERK AKT.-GES. Oct. 14, 1953 [Oct. 28, 1952]. No. 28304/53. Class 44. In a slide for slide fasteners of the type having two cooperating fastener stringers each comprising a row of closure members running through a bifurcated guiding channel of the slide, the slide comprising a manipulating member, a bracket, a slide body manufactured separately from the bracket and comprising two slide plates and a locking element provided on the slide body and having a projection projecting into the bifurcated channel for locking engagement in the intervals between the closure members in order to lock the slide against displacement along the rows of closure members, the manipulating member of the slide cooperates with the locking element on three different sides of the slide in such a way that a pull on the member results in movement of the bracket relative to the slide body, which movement retracts the locking element out of engagement with the closure members and out of the guiding channel. In the arrangment shown, upper and lower slide plates 3, 4 of a slide body 1 are provided with T-shaped members 6 and 7 respectively by which a U- shaped bracket 2 is attached to the slide body. The member 6 projects upwardly from a rib 10 extending over the plate 3 to form a forked member 11. A recess 12 in the rib 10 extending to the member 6 and provided with a space 13, houses a T-shaped, pivotally mounted locking member 14, one end 15 of which is provided with a pawl 17 adapted to engage, in the locking position, between the fastener elements. An upper portion 23 of the member 14 engages in a recess 21 in the bracket 2, the opposite lower portion 26 of the member 14 bearing against a projection 22 on the bracket. The slide is movable by means of a tab 27, which may be operated from either the upper or lower side of the slide, the tab being slidably engaged with the bracket 2. In operation, a pull on the tab, in the upper or lower position thereof moves the bracket in the same direction relative to the slide body, to release the locking member 14 against a spring 25, while a pull on the tab in the opposite direction, locates the heel of the tab against the rear wall 30 of the bracket 2 which is thus moved in a direction in which the portion 23 of the member 14 engages the bracket to release the member 14 against the spring 25.

Filed: 1924-12-01
Abstract: 248,439. Geiger, J. Dec. 1, 1924. Steam-engine and like indicators; pressuregauges, indicating means for, with damping- arrangement.-To determine the stroke-average pressure within the cylinder of a prime mover, pump or compressor, a piston 2, which is subjected to the fluid pressure in the cylinder through a fexible pipe connection, is connected by a link 36, a lever 5 and a link 17 to a rocking shaft 37 carrying a toothed arm 7 meshing with a pinion 8 on a shaft 38 provided with an inertia mass formed by a flywheel 3. The piston is normally held in a certain position of equilibrium by an exchangeable spring 4. A flat spiral spring acting directly upon the heavy fly-wheel may replace the spring 4. The magnification of the movement of the piston-rod may be varied by adjusting the position of the link 17 in the connection between the lever 5 and the rocking shaft 37. A diaphragm or a Bourdon tube may be used in place of the piston and the spring or in place of the piston alone. The movement of the flywheel may be damped by arranging the wheel in a chamber filled with oil, or a damping device such as a series of blades turning in a chamber fllled with oil or a cylindrical drum adapted to move in a closely-fitting casing may be fitted. The piston 2 moves in a cylinder 42 provided with a water jacket 43 and to prevent carbon being deposited on the end of the piston and in the cylinder 42 an exchangeable connection member 18 between this cylinder and the flexible tube leading to the engine cylinder is provided with one or more holes 19 by which the hot gases may be deflected from the wearing surfaces. Annular spaces 20 in the cylinder at the rear of the piston communicate with the outside of the casing and provide an escape for any gases passing the piston. Lubricant is forced between the piston and the cylinder from a chamber 63 by the pressure oil supply of the engine or by a hand pump 62. Adjustable tubular members 22 of yielding material act as buffers to limit the range of movement of the piston. The pressure is indicated by a pointer 24 directly connected to the fly-wheel and a permanent record is made on a rotating recording disc 25 by a writing point 23 actuated from an intermediate part of the transmission gear. The point 23 in the noload position moves clear of the disc.

Abstract: 639,741. Phase difference measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and COLCHESTER, C. D. Oct. 28, 1947, No. 28772. [Class 37] The phase delay produced by a line or network F at different frequencies is measured by modulating reference and variable frequency oscillations f1, f2 from O1, 02 with a lowfrequency #f from 03 in M1, M2 and feeding the outputs to the network F under test, applying the output from the network to demodulators D1, D2 together with the reference and variable oscillations respectively and comparing the outputs of the demodulators D1, D2. The low-frequency #f is less than the interval between successive frequencies at which testing is required. The network F is thus traversed by oscillations of frequency f1Œ #f, f2Œ #f, and the respective delays are B1Œ#Bf1 and B2Œ#B#2; on demodulation, two oscillations of frequency #f are obtained differing in phase by #Bf1 - #Bf2; these oscillations are made of equal amplitude by adjustment of attenuator A, and applied over low-pass filter LPF in opposition to a voltmeter V1 whose reading is thus related to the phase difference; alternatively, the output from D1 may be applied through a variable phase-shifting network to give a null indication in V1, the phase difference being that registered on the phase-shifting network.
