Abstract: 1,090,807. Fluid actuation of switches; switches held set and freed mechanically. P. H. SNOW. Oct. 12, 1965 [May 5, 1965], No. 18997/65. Heading H2B. [Also in Division G4] A warning alarm for attachment to a perambulator is actuated by movement of the perambulator, removal of the child from it, or by an animal, such as a cat, jumping on to it. The alarm comprises a toggle action switch which completes a circuit to a motor-driven bell or some other indicator, e.g. a siren or lamp. The switch-actuating mechanism comprises a three-armed member 5 pivoted on a pin 5a and a spring 7 connected between a pin 5b on one of the arms and a further pin 1b mounted on an axially movable rod 1. The rod 1 is pivotally joined at one end 1a to a further rod 2. To set the alarm, a key, or combination, mechanism is turned to rotate a cam 3 moving the rod 2 and the rod 1 axially to the left to project through a flexible bearing 1d and tension spring 7. The tip of the rod 1 is arranged to project between two spokes of a wheel of the perambulator, so that any movement of the wheel will deflect the rod 1 and cause the spring 7 to rotate the member 5 closing contacts 10a, 10b or 11a, 11b. The perambulator is provided with an air pillow connected via a pipe to a bellows 13c. With the child in the perambulator a screw 13b adjusted until aims 13g, 13h lie either side of pin 5b in the position any increase or decrease in weight on the pillow will cause the bellows to expand or contract, thus moving contacts 13g, 13h to deflect pin 5b and rotate the member 5 as before.

IPC: G03B27/72
Filed: 1953-07-10
Abstract: 748,712. Colour photography. PHOTOCHEMICAL CO., Ltd. Sept. 27, 1954 [July 10, 1953], No. 19172/53. Classes 98 (1) and 98 (2). Exposure characteristics for making a corrected colour positive from a colour negative are determined by forming separate groups of images of the latter by light passing through different steps of a grey wedge and through each of the three primary or other appropriate colour filters on to light-sensitive material, processing this, selecting images pertaining to each of the respective colour filters which have equal densities, and computing exposure periods appropriate to each filter for attaining images of equal density from the characteristics of the grey wedge; which latter may, conveniently, have four steps transmitting successively the whole, a half, a quarter and an eighth of the light incident upon it. Further trial positive images may then be made by exposure through the grey wedge and successively through each of the filters using exposures computed as above, to evaluate the exposure period for attaining the optimum overall density. Apparatus suitable for the method has a housing 1 telescoping into a housing 2 having a base 3 forming a well, for the light-sensitive material 4 and grey wedge 5; housing 1 is provided with twelve lenses in groups 61 to 64 and provision for receiving colour filters 7<SP>1</SP> to 7<SP>3</SP> extending over the steps of the grey wedge. In use the apparatus may be placed on the easel of an enlarger (without its lens), adjusted to focus the twelve images on the base 3 and subsequently illuminated for a period as of twenty seconds to effect the exposures. For the further trial positives referred to above one colour filter at a time is used to cover all the lenses and give positives of four density variations, or, if desired, additional colour filters may be placed over the second and third rows of lenses to show the effect of colour bias.

Filed: 1974-03-25
Abstract: 1463808 Fluid-pressure servomotor systems IV PRESSURE CONTROLLERS Ltd 25 March 1974 [19 April 1973] 19197/73 Heading G3P An unloading valve for a hydraulic pump comprises a non-return valve 4 between an inlet 1 and a supply outlet 3 and a return valve 13, between the inlet 1 and a return outlet 15 connected to reservoir, controlled by a two way pilot valve 8. Fluidpressure on the outlet side of the non-return valve is fed to the inlet 7 of the pilot valve which opens, when a predetermined pressure is reached, to admit the fluid, via duct 11 and opening 12, to an operating cylinder to open the return valve 13. The pilot valve is designed to reseat only after a fall in pressure in the system, for example of 20 to 25%. To this end the seat diameter "Y" is less than the valve stem diameter "Z". This produces a popopen action and the pilot'valve remains open until the desired drop in pressure in the system has been achieved. The operating cylinder is connected to the return outlet 15 via a branch duct 11A having. a restriction 11 B. The return valve 13 is pressure balanced, diameters "V" and "W" being closely similar. The piston diameter "X" may or may not be similar to "V" and "W".

Abstract: 624,968. Push-button tuning mechanism. GENERAL MOTORS CORPORATION. July 18, 1947, No. 19251. Convention date, Feb. 15, 1940. [Class 40 (v)] In a push-button tuning mechanism the tuning elements 20, Figs. 2 and 3, which may be movable magnetic cores, are connected to a member 76 which is movable about a pivot 70 and is biassed in an anticlockwise direction by a spring 78. The buttons 14 are attached to threaded rods 30, which are biassed outwards by springs 36, and carry threaded angled brackets 42 provided with an extension running in a slot 52 to prevent them from turning. The rods 30 are locked in their innermost position by the spring-biassed plate 64 and as one rod is pressed in, the plate is forced down to release any other rod which may be locked in. The shaft 74, which is attached to shaft 76 by links 72, co-operates with any of the adjustable brackets 42 to operate the tuning elements. The position of the brackets on the threaded portions of the rods determines the position of the tuning mechanism 18, 20, and may be varied by rotating the rods, a spring 56 ensuring that the brackets remain in a set position. When the manual tuning knob 10, which is connected to a rod 30<1> substantially identical with the other rods, is forced inwardly, the mechanism locks over the plate 64, and the knob may be rotated to cause the angled bracket 42 to travel, turning the lever arm 72 about the pivot 70 until the desired station is received. The Specification also describes mechanism.for transmitting the movement of the lever arm 72 to an indicating needle.

A protective arrangement for banks of parallel capacitors connected in series with a transmission line has a current transformer whose secondary is energized on flash-over of a spark gap, shunting the whole bank, or unwanted asymmetry in the capacitor bank. In Fig. I four groups of capacitors 3 ... 6 are arranged symmetrically in line 1, 2 so that no current normally flows in primary 14 of a current transformer 11 which has a second primary 13 in series with the spark gap 8. Unwanted asymmetry in the capacitor groups will produce a current in the secondary 12 sufficient to operate relay 23, to connect terminals 24, but a second relay 21 remains inoperative so that circuit 22 is not completed. Flash-over of the spark gap 8 will produce sufficient current to operate both relays 21, 23, but only circuit 22 is completed. In Fig. 2 the current transformer 11 has only one primary 13 in series with the spark gap 8 and the secondary of another current transformer 16 in the symmetrical connection of the capacitor banks. In Fig. 3 the two primaries 14, 15 of a current transformer 11 are in series with capacitor groups 3, 4, respectively, and connected in opposition so as normally to balance.

Abstract: 147,901. British Metal Spray Co., (Assignees of Schoop, M. U.). Feb. 19, 1914, [Convention date]. Coating; coating non-metallic surfaces with metals.-In a process for coating surfaces with metals or other fusible substances, the fusible substance in the form of wire is melted electrically and the molten product projected on to the surface to be coated by a current of gas. In the apparatus shown, wires w<1>, w<2> of the fusible substance, arranged to cross each other as shown, are fed automatically through tubes a, b, one or both of which is elastically supported. An electromagnet c, energized by a current passing from l' through a, b and c to l<2>, draws wire electrode w<2> away from electrode w<1>, forming a small arc and fusing the metal. This molten metal is then sprayed on to the surface to be coated by a blast of gas from a pipe n which also extinguishes the arc so that the magnet allows the electrodes to approach each other again, when the same operations are repeated. The vibration of the wires may be effected by other than magnetic means, and in the case of magnetically effected vibration an electric current, independent of the main circuit supply current to the electrodes, may be used. The angle between the tubes a, b is preferably about 45 degrees.
