Title: Electromagnetic relay
Inventor: GREEN BERTRAM ARTHUR
IPC: H01H50/04
Filed: 1961-02-11
Abstract: 923,804. Electromagnetic relays. ERICSSON TELEPHONES Ltd. Dec. 4, 1961 [Feb. 16, 1961 ; June 13, 1961], Nos. 5177/61 and 21225/61. Class 38 (5). An electromagnetic relay has two mating half-bobbins 1, 2 for its coil (not shown), which fit over a flat core 4 having extensions 5 which serve to retain the inturned ends 16 of the armature 15 in recesses 10 of the half-bobbin 2. An armature back-stop 14 projects from the half-bobbin 2 which also carries terminals 12, 13 for the coil. The core 4 is held against a reference face of the recess 3 in the half-bobbin 2 by a spring 18 and the residual gap between the armature 15 and the lower face of the core end is set by a thin strip of adhesive film 17. A number of such strips may be superposed and one or more can be moved to the underside of the armature 15 to change the residual gap without altering the armature travel. A bolt (Fig. 2, not shown), in a slot 7 secures a bracket 19 to the half-bobbin 1 with a projection 23 located in a recess 11 in the half bobbin 2. Clips 21 support contact spring sets 22, as described in Specification 923,805, with bendable arms 30, 32 setting the positions of return springs 29 and stops 31 for the spring-controlling combs 27. The spring 18 may have an extension (Figure of the second Provisional Specification, not shown), which has slots fitted over the eore end and stops 31 to fix their relative positions. The core 4 may be part of a magnetic frame common to a number of relays.

Title: Photographic Camera
Inventor: HARVEY DONALD MALCOLM
IPC: G03B7/16
Filed: 1968-02-01
Abstract: 1,198,343. Cameras for flash exposures. EASTMAN KODAK CO. Feb. 1, 1968 [Feb.6, 1967], No.5223/68. Heading G2A. A supplemental optical element can be moved into or out of alignment with the fixed focus lens 13 of a camera in response to movement of a camera element preparing the camera for a flash exposure. In Figs. 1 and 2 the said optical element is a flat plate 29, which has the effect of extending the focal length of the lens so that the image of a distant object is focused on the film plane 14. Plate 29 is carried by a lever 33 pivoting on a pin 32, the lever being urged anti-clockwise by a spring 35 so as to rotate the plate out of alignment with the objective lens 13. However, when the drawer 18 carrying the flash bulb 21 is retracted inside the camera, lever 33 is pushed against the spring so that plate 29 is in line with the lens. When the flash drawer is extended into the operative position (broken lines in Fig. 1), the plate 29 is allowed to rotate out of alignment with the lens. Thus the flash will effectively illuminate subjects which are closer to the camera than the hyperfocal distance of the fixed focus lens. Instead of a flat plate, the supplemental element may be a negative lens, which is moved into alignment for flash purposes. Fig. 4 (not shown) is a modification in which the attachment of an auxiliary flash unit similarly controls the movement of the supplemental element.

Title: Improvements in or relating to a device for the magnetic and electrical treatment ofwater and other materials
IPC: B01J19/08
Filed: 1957-02-15
Abstract: 852,733. Treating water. VIOLET, M. Feb. 15, 1957 [Feb. 17, 1956], No. 5328/57. Class 46. An apparatus for subjecting a material (e.g. water) first to the action of oscillatory magnetic energy, and then to the action of artificial or natural sources of oscillatory electrical energy, comprises a first means for subjecting the material under treatment to the action of an oscillatory magnetic field and a second means for subjecting the material under treatment, after it leaves the first means, to high frequency electrical oscillations, the second means including a fixed condenser having a dielectric composed principally of beeswax, and one or more electrodes which serve to transmit the electrical oscillations to the material under treatment. The electrical oscillations may be natural in origin, taken from an aerial, or of artificial origin, taken from the electrical supply system. The electrodes may consist of a metal or alloy and may be coated with a metalloid such as arsenic or antimony or a non-metal such as carbon or sulphur. It is stated that, by the use of copper electrodes, some of the copper may be dispersed (in colloidal, molecular or ionic form) in water. In the Figure, water is passed through tube 1, chamber 2, tube 7, tube 8 and finally into storage receptacle 10.. The constricted portion 3 of chamber 2 lies between the poles of an electromagnet 6 fed with alternating current from source 18. Copper electrodes 9 and 11, in tube 8 and receptacle 10 respectively, are connected to fixed condenser 12 and to the movable blades 13 of a rotary condenser, the two condensers being arranged in parallel. Condenser 12 has a dielectric consisting of beeswax. The fixed blades 14 of the rotary condenser, and the remaining terminal of the fixed condenser 12 are connected to the live side of the A.C. source 18. The movable blades 13 of the rotary condenser are driven by motor 15. In alternative arrangements, the fixed condenser and the rotary condenser may be connected in series, of the rotary condenser may be replaced by a high frequency generating device, for example one involving a quartz crystal type valve circuit.

Title: Improved means for regulating the dryness of web material
IPC: D06C7/00
Filed: 1960-02-15
Abstract: 947,211. Automatic control systems. J. G. BAERT. Feb. 15,1960 [Feb. 17, 1959; Oct. 28, 1959], No. 5362/60. Heading G3R. [Also in Division D2] Web material such as paper to be dried to a predetermined level of dryness passes over a number of cylinders 2 and a pilot cylinder 3 all supplied with hot vapour passing through pipes 1 and 4. Thermocouples 10 and 11 responsive respectively to the temperature of the outer surface and interior of the cylinder 3 produce a voltage representative of the quantity of heat, and thus the drying effect, transferred to the paper by the cylinder 3. This voltage is converted by a known device 14 into a static fluid pressure transmitted to a known modulator 16 where it is compared with a reference pressure indicative of the degree of dryness desired, the resulting "difference" signal being transmitted to a regulator 6 controlling a vapour supply valve 7. The heating effect is thus automatically adjusted to produce the desired dryness level, irrespective of such factors as speed of travel,thickness of paper &c. The thermocouples may be replaced by other suitable temperature measuring means, and the control system may be purely electrical, purely pneumatic or hydraulic, or electrical and pneumatic (or hydraulic) as shown.

Title: A Self-Regulating Circuit Switch.
Inventor: MORTIMER AUSTIN JOSEPH
IPC: H02M1/08
Filed: 1968-02-02
Abstract: 1,164,983. Voltage regulators. RADIO CORPORATION OF AMERICA. Feb.2, 1968 [Feb.2, 1967], No.5496/68. Heading G3X. A voltage regulating circuit comprises A. C. input terminals 10, 30; output terminals 18, 20 for connection to a load 19; a series thyristor 15 having its control electrode 16 connected over a resistor 27 to a biasing battery 29; a series arrangement of a diode 21, variable resistor 23 and capacitor 25 connected as shown across the anode-cathode path of the thyristor; and a resistor 31 connecting the control electrode 16 to the junction of resistor 23 and capacitor 25. The arrangement is such that the capacitor 25 charges up to a voltage the value of which is a function of the supply voltage when terminal 10 is negative with respect to terminal 30, i. e. during the negative half-cycle of applied voltage, and this capacitor voltage Vc, at the summing junction S between resistors 31 and 27, opposes the biasing voltage Vb from the battery 29. When Vc has decayed to a value such that Vb-Vc equals the voltage required to trigger thyristor 15, the thyristor will be rendered conductive at a point in the positive half-cycle of applied voltage and remain conductive for the remainder of the halfcycle. If the applied voltage is low the thyristor will conduct early in the half-cycle and if high later in the half-cycle since Vc is a function of the supply voltage. The mean voltage applied to the load is thus automatically regulated for source voltages of various magnitudes.

Filed: 1918-03-28
Abstract: 131,037. Whitehead Torpedo Works, Ltd., and Lees, E. March 28, 1918. Addition to 127,662. Torpedoes, locomotive.-Relates to gyroscopic steering-apparatus provided with a pointer for indicating the direction in which the torpedo shall turn on discharge, as described in the parent Specification. According to the invention, the pointer is interlocked with the dial or dials indicating the angle through which the torpedo shall turn by means of Geneva stop-gear. In the form shown, a minutes dial A and a degrees dial B are used as described in Specifications 126,689 and 130,426. The pointer a is moved to one side or the other about the same axis as the dials by finger-grips F, and, by means of a sector a<1>, moves a rack b to one side or the other. This rack carries a. downwardly projecting lug h which, in the middle position, lies between two segmental projections i, m on a Geneva stop-wheel o geared to another Geneva stop-wheel e operated by a stud d on the dial A. When the pointer is moved to one side, one of the projections of the wheel o is released, and the dials can be set in one direction for a given angle until the lug h bears against a stop on the wheel o, the lug h being meanwhile held in its set position by the periphery of one of the projections on the wheel o. When the dials are returned to zero, the lug h snaps in between the projections i, m, under the influence of springs r, t acting through a rack p and sector a<2>, and the pointer is simultaneously brought back to the central position. The pointer carries a screen E for shutting the windows v, w when the pointer is in the central position, and for opening one part or another of the windows when the pointer is moved to one side or the other, to permit the corresponding scales of the dials A, B to come into view.

Carbon; sulphur.-Apparatus for the collection of flowers of sulphur, carbon, &c. from gases comprises a row of chambers arranged side-by-side, one of which receives from the two adjacent chambers. Each chamber may have a longitudinal trough into which the deposit is directed by sloping walls, the space behind these walls serving for the circulation of a heating or cooling agent. In the construction shown in longitudinal section in Fig. 3, and in partial transverse section in Fig. 4, each chamber contains two troughs, which may be formed by low walls 20, 23. The two intermediate sloping walls 28, 29 may be supported by a central wall 31 or by pillars. An outer wall of the chamber may be made double, the intermediate space being closed so as to provide a heatinsulating air jacket 43, or being supplied with hot or cold air from the space behind the sloping wall 26. Further heating or cooling may be effected by hollow columns or pilasters 46 within the chambers or in the walls or transverse partitions 41, which are provided with apertures 42. The deposit collecting in the troughs may be removed by scoops 33 guided by grooves in the walls of the troughs and operated by cables, or in one direction by gravity if the troughs are inclined. When out of use, the scoops may remain outside the chamber, if there is only one scoop per trough; if more scoops are used, some of them may remain in the troughs, below the transverse partitions. Doors are provided where the scoops enter and leave the chamber. The material may be delivered into a pit across which the scoops are carried by rails. If there are seven chambers in a row, the fumes may first enter the first, third, fifth, and seventh chambers. From the first and third chambers the gases pass in the reverse direction along the second chamber. Finally all the gas passes in the original direction through the fourth chamber, and escapes into the atmosphere, through filters if necessary. In the second, fourth, and sixth chambers the troughs may be separated only by a single wall with a bevelled top, these chambers being narrower than the others. All the troughs slope one way towards a common pit. Ventilation openings and blowing fans may be provided in order to remove fumes rapidly when access to the interior of the chambers is required.
