Title: Improvements in automobile signals
IPC: B60Q1/34
Filed: 1919-02-27
Abstract: 142,586. Gibson, W. E. F., and Amos, C. B. Feb. 27, 1919. Motor-road-vehicle signals. - An automobile signal for indicating the direction in which a car is about to turn, or for signalling to a car in the rear to stop, comprises rotary casings arranged at the front and rear of the car, and adapted to be rotated about vertical axes from a position longitudinal of the car to a position transverse thereto by electro-magnetic means, the circuits to the electro-magnets being simultaneously controlled by a rotary switch arranged on the steering-column o f the car. The signal comprises casings as 1, Figs. 3 and 4, of bird-shaped or other outline, and formed at the sides with openings as 79, Fig. 1, in the form of a hand behind which is arranged a red glass 81, Fig. 4, or formed so as to show the word " stop." The casings 1 are held in their normal positions by catches 39 which fit in recesses 40 in small uprights 41 fixed to the baseplate 3, to which is attached a fixed pivot 6 about which the whole casing 1 can rotate to a limited extent, the casing being formed with a sleeve 2 which rotates on ball bearings 8, or the like. To rotate the casings 1 to give a signal, a switch device 42, Fig. 6, is operated to send currents through coils 14 of electro-magnets 11, 12. between the poles of which are mounted armatures 19 constructed with coils 22 and pole-pieces 24, 25 which are magnetized when the main switch is closed, the whole armature being thus rotated in one. or other direction according to the direction in which the main switch arm is moved. The rotation of the armature 19 causes the casing 1 to move about a vertical pivot, owing to the engagement of a bevelled gear 23 on the armature with a fixed bevel-gear 7 on the pivot 6. The armatures are returned to their mid-positions by springs 30, 29 when the current is cut off, and they are held in this position until the catch 39 is released by energizing an electromagnet 35 at the same time that the main switch closes the circuits of the coils 14 and armatures 19. This switch may also control the lighting of electric lamps 31 arranged in each casing 1, so as to cause the signals to be visible at night. The rear casing may be fitted with a light which serves as the ordinary rear light and also illuminates the license tag. The switch lever 42, Fig. 6, is formed of insulating-material and is provided with a pair of spring-pressed plates 55, 56 which move over segmental plates mounted in an insulated disk 43 attached to the steering-column 44. The lever 42 is limited, as to its movement in either direction, by stops, and is fitted with a transverse member for controlling the current to the electro-magnet 35; it is also fitted with a contact 98 which can be depressed against the action of a spring to actuate an electric hooter.

Abstract: 1383642 Foamed hydrogen-peroxide-modified polymers INTERNATIONAL SYNTHETIC RUBBER CO Ltd 18 Feb 1972 [19 Feb 1971 14 June 1971] 4991/71 and 27747/71 Heading C3C A foamed hydrogen-peroxide-modified polymer is made by foaming a dispersion, which has been obtained by treating a colloidal aqueous dispersion of an unsaturated polymer with hydrogen peroxide in the presence of a hydrogen peroxide activator which does not encourage the decomposition of the peroxide to produce molecular oxygen under the conditions of the treatment, and drying the foamed dispersion during or after the cross-linking of the polymer, hydrazine having been added to the dispersion prior to or during the foaming thereof. The polymer may be derived from a natural or synthetic rubber. In the Examples 1-6 a butadiene-styrene copolymer latex was treated with hydrogen peroxide in the presence of sodium tungstate or sodium tetraborate, and then potassium oleate and hydrazine or its hydrate were added; the dispersion was then compounded with gelling and vulcanizing agents, and optionally whiting, and the dispersion was then foamed in a mixer, moulded, gelled, crosslinked and dried; in Example 4 the foam was gelled and cross-linked using radio frequency radiation; and in Example 7 the modified polymer latex was compounded to a non-gel formulation before foaming by addition of a surfactant, sodium lauryl sulphate, sulphur, zinc dithiocarbamate, zinc oxide, an antioxidant, whiting and sodium hexametaphosphate.

Title: Side looking sonar apparatus
IPC: G01S7/62
Filed: 1972-02-03
Abstract: 1326517 Sonar WESTINGHOUSE ELECTRIC CORP 3 Feb 1972 [24 March 1971] 5029/72 Heading H4D A sonar apparatus includes a transmitter transducer for projecting acoustic energy on to a portion of a target area, a receiving transducer means and a receiver for forming a plurality of receiving channels for receiving reflected energy from a plurality of adjacent elongate strips on said target area, the total area of said portion being at least equal to that of said strips and display means for indicating received acoustic energy from each of said strips as a function of time. In a side-looking sonar the transmitter transducer is a single element and the receiver transducer comprises a number of elements arranged on the arc of a circle of radius fifty feet so that when towed it is focused on the sea bed from that altitude. The transmitting transducer illuminates a portion of the sea-bed N times as great as the area from which each of the N receiver channels receives energy since the receiving array is N times as long. Each transducer in the receiving array is connected through an amplifier and mixer to a delay time which has ten taps. The difference between consecutive taps is given by: where L is the length of the transducer; # is the wavelength; d n  is the displacement of the receiver strip from the axis and S n  is the maximum slant range for the strip. Corresponding taps on each delay line are fed to ten summing and detecting units whose outputs feed the display. The receiver strips thus produced are hyperbolical (Fig. 7A). For a linear scanning mode a display unit shown in Fig. 14, may be used. Conductors 114 represent the receiver strips and are connected to the summing unit outputs. Insulating block 117 is moved by cam 124 and follower 122 transversely across the recording medium 110 for each transmitter pulse. Conductor 119 is earthed and thus a record of the received signals from the receiver strips is recorded. Medium 110 is moved in synchronism with the speed of the carrier. In a circular scan mode a similar display is used wherein the arrangement of conductors and cam follower is rotated in synchronism with the rotation of the transducers (Fig. 15, not shown). The display may alternatively be a storage CRT or a photographic film used in conjunction with a CRT. The receiving transducer array may be made of N separate arrays each differently oriented to receive from a different strip on the sea-bed (Figs. 16-17, not shown). The transducer housing may be rectangular or spherical depending on the operating mode and the aperture is covered with a rubber to match the acoustic impedance of the sea-water. The housing is also filled with a matching fluid. The transducers may be magneto strictive or barium titanate or lead zirconate titanate.

Abstract: 1,056,858. Removing container caps. FORDS (FINSBURY) Ltd. Feb. 7, 1964, No. 5032/63. Heading B8T. A metal foil or other cap sealed over the mouth of a bottle or other container is released by a machine which advances the bottle to a position where depressing means actuates to depress the cap into the bottle and thereby release or loosen the cap skirt from sealing engagement with the container mouth. Containers sealed with metal foil caps are fed to the machine by a belt 50 and are then engaged by a screw conveyer 15 which advances them slightly faster than the belt below a rotating drum 41 with radially extending probes 42. As each container moves under the drum a probe depresses the central part of the cap to loosen it; the containers disengage the screw conveyer and are carried away by the belt. The drum and screw conveyer are driven from an electric motor 4 via reduction gearing 5 and a main shaft 8; the drive to the drum includes bevel gearing 37, 38, and the drum and its drive are vertically adjustable. The drum is also axially adjustable on its shaft 33. The drive to the screw conveyer from the main shaft is via bevel gearing, a chain 26, and sprockets. A blowing or suction device in the path of the belt removes the loosened caps and delivers them to a collecting arrangement from which they are fed between compression rollers and flattened and passed to a receptacle:
