Patent GB-454919-A (GB)
Abstract: 454,919. Depositing metals by electric discharge. TENNANT, W. J., 111, Hatton Garden, London.-(Grupe, W. F. ; Lyndhurst, New Jersey, U.S.A.) Jan. 4, 1935, No. 369. [Class 41] Gold leaf or like metal foil is made by depositing the metal on a. moving carrier-band by cathode dispersion in an atmosphere of an. inert gas such as argon and afterwards separating the foil by solution or melting of the band or of a superficial layer thereon. In the apparatus shown, the carrier band is passed in a curved path close to the cathode constituted by a gold lining 27 on the container 13. The conveyer comprises an endless band 45 moving over drums 31, 41, 46 and guide members 42 and and a band 47 moving over drums 32, 14, 48 and guides 142. The carrier band is unwound from a drum 128 passing over drums 129, 41 from whence it is carried by the outer limbs of the two conveyer bands passing on return close to the issuing material to be wound up on a drum 30. The drums 30, 31, 32 are driven from a shaft 56 by an electric motor 54. The carrier band divides the vacuum chamber substantially into two parts to the outer of which argon is supplied from a cylinder 53, the inner space being exhausted through a pipe 50. The supply of gas is controlled by a pressure gauge 62 through an electric relay 66. The container 13 is surrounded by a jacket 11 through which cooling liquid is circulated. It is provided with a cover and a base member which are also cooled. The carrier-band may be of metal ; in this case a paper band is applied to the deposited film by a heat-releasable material such as varnish or wax and the carrier band is removed by floating on a solvent liquid. The paper may be applied to the edges only after removal of the metal carrier the edges are removed by slitting, leaving the deposited metal as a free foil. Alternatively, the carrierband may be of cellulosic material, such as that known under the Registered Trade Mark " Cellophane," coated with suitable material. Specifications 333,246, [Class 41], and 367,074 are referred to. The Provisional Specification also describes the introduction into the apparatus of a minute quantity of the vapour of a metal such as mercury, sodium or magnesium having the property of diminishing the surface tension of gold ; Specifications 211,539, 252,710, 275,523, and 276,291, [all in Class 41], are referred to therein.

Title: Photographic camera
IPC: G03B7/091
Filed: 1974-10-22
Abstract: 1482658 Multiple exposure arrangements FRANKE & HEIDECKE GmbH 22 Oct 1974 [13 Nov 1973(2)] 45698/74 Addition to 1433814 Headings G2A and G3N In the micro-processor controlled camera disclosed in the main Specification 1433814 there is provided an additional circuit which, when selected, interrupts the normal picture taking sequence at a predetermined switch stage by setting the step by step switch back to a previous switch stage. As described, when the central line (5) is activated by output 9 of the step by step switch, instead of the film wind motor operating, the motor power is shunted via switch MW and causes transistor 302 to conduct, whereupon a potential appears at the base of transistor 303 to short circuit the base of transistor 304 through 303, thereby removing the short circuit across capacitor 403. A pulse subsequently appears at output 12 and also at line 404. The pulse at 12 is fed to the "master clear" input of the step by step switch, Fig. 3 of Main Application (not shown), to return it to switch step zero from where it proceeds on a further picture taking sequence until at step 9 the process repeats itself. The pulses on line 404, one for each repeat of the cycle, are counted on a counter 500 which has a plurality of outputs, the identity of the activated output depending on the number of pulses counted. A contact arm 5 can be set so that after a selected number of pulses, and hence repeats of the cycle, the signal is fed to the base of transistor 504 whereby transistor 502 is cause to stop conducting. Transistor 302 therefore stops conducting and on subsequent actuation of control line 5 by switch step 9 the wind motor is no longer shunted out and no pulse is emitted at (12). The programme proceeds in the normal way until the camera shuts down. On re-switching on the camera the starting surge via capacitor 508 resets counter 500. In order to take a rapid sequence of exposures an auxiliary clock 600 may clock the step by step switch of the main camera through the switch steps from zero to six, opening of shutter, before the next pulse of the main camera clock IIIa. The circuit 700 stops clock 600 after the required number of pulses. As described three pulses are employed, the "measurement button" camera made being used to step directly from "zero" to "four" on the first pulse. This rapid pulse sequence relies on the exposure remaining constant and the mirror and auxiliary shutter remaining stationary in the taking position throughout the whole series of repeated exposures.

A universally mounted shift lever 1, controlling valves which admit compressed air to engage ratios of a four-speed and reverse gear (not shown), has a projection 26, 27 which cooperates with a pivotable baulk plate 28 so that movement of the lever 1 to its 4th ratio position moves the baulk plate to an operative position in which it allows the lever 1 to be moved from 4th ratio only to 3rd, and movement of the lever 1 to its 3rd ratio position moves the baulk plate to an inoperative position. A spring-loaded ball detent 31 engages recesses 29, 30 in the baulk plate 28 in its operative and inoperative positions respectively. When the lever 1 is moved into the 3-4 ratio establishment plane 7, the projection 7 passes through a slot 33 in the baulk plate 28. Movement of the lever 1 to the 4th ratio position pivots the baulk plate 28 to a position (Fig. 5B) in which a lip 27 prevents cross-shift movement of the lever 1 out of the 3-4 shift plane (Fig. 5C, not shown). Movement to the 3rd ratio position (Fig. 5D) pivots the baulk plate to its inoperative position, in which cross-shift is not inhibited. The lower end of lever 1 carries a roller 8 which engages rocking levers 14, 13, 11 selectively for 3rd-4th, 1st-2nd, and reverse establishment respectively. These levers control five similar valves, each of which has a spool 16 which in its released position is spring urged upwardly (Fig. 2) to connect a respective line 25 from ratio establishment means to an exhaust gallery 17, and in its operated position engages and moves a valve member 21/22 to close the exhaust line and to allow compressed air from an inlet chamber 23 to enter the line 25.

Abstract: 1371526 Photo-electric position finding systems S W JORGENSEN and P M JOHNSON 26 Oct 1971 49787/71 Heading H4D [Also in Division G4] A beacon for providing an observer with an indication of his angular position with respect to a reference line on the beacon comprises a radiation source 10 and a rotating drum 14 with a mask having opaque and transparent portions 16 arranged in n "bit" groups to define 2<SP>n</SP> angular positions. In the illustrated embodiment a light system is used but other radiation, e.g. microwaves, can be utilized. Light rays from source 10, e.g. a xenon flash tube, and mirror 12 pass through transparent portions of the mask and are focused by projection lens 18. The light rays are formed by aperture 28 and an optional beam spreader (29) (Fig. 1A, not shown) into horizontal fan-shaped beams 26. The mask, Fig. 2, is divided into regions 30 to 42, "bit" groups 32-42 being provided, black areas being opaque. As the light rays are formed into beams 26 the sequence of received light impulses depends upon the vertical angular position of the observer, with respect to, e.g., the centre line of the mask, the mask of Fig. 2 allowing 64 (2<SP>b</SP>) angular positions to be determined. For example, sequence 58 illustrates impulses received for a position in which the observer's line of sight is 1 "resolution element" (half the vertical width of a black or white portion of region 40) down from the centre line of the mask. Sequences 60, 62 and 64 correspond to positions 2, 3 and 3¢ resolution elements below the centre line respectively. The light source may be excited continuously or flashed whenever a region 30-42 is fully within the slit defined by aperture 28. In the latter case the cylindrical drum is preferably replaced by a polygonal drum (14<SP>1</SP>) (Fig. 1c, not shown), each face of which carries a particular region 30-42. The receiver may comprise a collecting lens (44), (Fig. 3, not shown), detector (48), amplifier (50), impulse memory (52), decoder (54) and meter read-out (56). If the drum is rotated slowly enough unaided human observation may be used and in this case a Morse type code replaces regions 30-42 (Fig. 5, not shown). According to his position the observer will receive a particular sequence of short and long pulses, a warning signal (82) being provided on the drum mask to indicate the start of a new code cycle. The observer can then refer to a decoding table (Fig. 6, not shown) to determine his position. Although the described embodiment only gives information as to vertical position, a second identical device may be provided at right angles and operating a different wavelength to give horizontal information.
