Patent GB-731268-A (GB)
Title: Improvements in or relating to the production of photographic multi-colour images
Inventor: MEEUSSEN LOUIS ACHILLES
IPC: G03C7/18
Filed: 1952-05-07
Abstract: 731,268. Colour masking images. GEVAERT PHOTO-PRODUCTEN N.V. April 29, 1953 [May 7, 1952], No. 11541/52. Drawings to Specification. Class 98 (2). Masking images are produced in a photographic multilayer material having colour couplers in the emulsion layers by colourdeveloping the exposed material to a negative image in a colour developer containing no colour formers and re-exposing it to light of a selected colour during the colour-development. The material may be removed from the colour developer, re-exposed from one or both sides to coloured light and then re-immersed in the colour developer, in which case the material may be given a short rinse before re-exposure, or the re-exposure may take place while the material is in the colour developer or while the material is being transferred to a first rinsing bath after colour development or even during such a final rinse. The photographic material may comprise from front to rear, layers sensitized to blue, green and red, containing colour couplers to give a dye complementary to the respective sensitivities, and with a yellow filter between the blue and green layers. Such material may be re-exposed to green light from the rear or from the front and rear, and/or to red light from the front during colour development. However, the layers may be in a different order, e.g. sensitized to green, red and blue from front to rear and such a material may be reexposed to blue and red light from the front, and green light from the rear during colour development.

Title: Improvements in garment pressing machine
IPC: D06F71/34
Filed: 1940-07-11
Abstract: 542,561. Garment presses. UNITED STATES HOFFMAN MACHINERY CORPORATION. July 11, 1940, No. 111572. Convention date, Oct. 16, 1939. [Class 138 (ii)] In a garment press having a steam supply to the head and the buck for spraying steam on to the operative face provision is made for actuating the spray means in the pressing members selectively, and such action may be effected by a foot pedal thus leaving the hands of the operator free. As shown in Figs. 1, 2 and 6 the spray of steam in the head 17 is controlled by a valve 33, and that in the buck 13 by a valve 29: these valves being suitably of the type described in Specification 539,248. The valve 33 is normally held closed against the steam pressure by a spring 30 on a pivoted lever 41 acting through a link 36 which is pivoted to a link depending from the lever 41 and to a lever 35. A lever 39 connected to the lever 41 is connected by a rod 42, bellcrank 43, rod 46, bellcrank 47 and rod 49 to a loose collar 52 on a spindle 53 which also carries a fixed collar 71 and another loose collar 57 on which a selecting lever 56 is pivoted, and which is operated by a rod 63 from a pedal 65. When the selecting lever 56 is in the position shown in Fig. 2 depression of the pedal to rock the collar 57 effects rocking uf the shaft 53 thereby through rod 31 opening the steam valve 29 in the buck against the action of a spring 73. When however, the setting lever 56 is rocked to the dotted position, Fig. 2, depression of the pedal 65 opens, through the linkage described, the valve 33 to admit a steam spray to the head. In a modification the linkage referred to may be replaced by a Bowden wire mechanism. When the lever 56 is set so that operation of the pedal opens the valve 29 to the buck steam may be simultaneously admitted to the head by the operation of a finger lever 35 adjacent to handle 27 of the head: operation of this lever rocks the link 36 to permit the valve 33 to open.

Abstract: 479,574. Roads. HALBACH, K. April 29, 1937, No. 12217. Convention date, April 29, 1936. Addition to 460,279. Drawings to Specification. [Classes 20 (iv) and 107] The method for the production of a mortarbound road covering, claimed in the parent Specification, is modified by using for the temporary layer, through the intermediary of which the covering is compressed, layers of a continuous material, such as webs of paper, cardboard, fabric, sponge-rubber, or the like. The compression may be effected with one or more further layers, such as sand, applied to the continuous layers. The covering, which may be of concrete, may be formed in several layers, each of which is adapted to be compressed with the use of the continuous layers. The mortar for the road covering may be formed of trass-cement, trass-lime-cement, or ordinary cement with the addition of bitumen. The joints in the road covering may be filled with an elastic material, such as a mixture of tar and sand, and these joints may be compressed during the compression of the covering. The Specification as open to inspection under Sect. 91 describes also the use of the following materials for the temporary layer, viz. : foundry sand, pumice-stone, sawdust, chopped straw, jute or paper fibres, bitumen, bitumen emulsions, tar, resins.

Title: Improvements in or relating to magnetic anomaly simulators
IPC: G01R33/00
Filed: 1961-04-05
Abstract: 908,423. Magnetic anomaly simulators. CANADA, MINISTER OF DEFENCE. April 5, 1961 [May 12, 1960], No. 12221/61. Class 119. Relates to magnetic detector systems used in aircraft to detect ships or submerged submarines by detecting the irregularities (known as " magnetic anomalies ") caused in the earth's magnetic field by the presence of the ship or submarine, and in particular to a simulator providing an output which is fed into a magnetic detector, the output simulating the signals generated due to magnetic anomalies detected during the operational use of the detector, and thus permitting training of operators in the recognition of the characteristics of these signals. According to the invention the simulator comprises a voltage divider 116 having a plurality of connections adapted to be connected across a source 118 of direct current voltage; a rotary potentiometer 111 having a continuous resistance element, a plurality of taps 1-26 and a wiper 112, a motor 120 for rotating the wiper 112 and a multi-position selector switch 115 connecting the taps of the potentiometer 111 to connections of the voltage divider 116 so as to provide a different set of connections for each position of the switch. Connections 110, 110a supply an output voltage from the rotary potentiometer 111 to a magnetic detector element 114 of a magnetic detector system, this output voltage simulating a signal generated due to a magnetic anomaly. The frequency of the signal is determined by the speed of the wiper 112 which can be varied by means of a variable ratio speed changer 119 and the amplitude is controlled by resistors 113 connected in series with the voltage divider 116 and the D.C. source 118, this allowing simulation of the vertical separation between submarine and aircraft. A switch 117, by means of a mechanical connection (shown in dotted lines) to the speed changer 119 adjusts the speed of the wiper simultaneously with switching in different resistors 113. The waveform of the output signal is generated as the wiper 112 rotates and the 5-position selector switch 115 permits a choice of five different waveforms. A reversing switch 128 allows simulation of flight in either direction along a given path over the submarine.
