Patent GB-499467-A (GB)
Abstract: 499,467. Aiming practice for automatic guns. GALLUSSER, H. Aug. 12, 1938, No. 23824. Convention date, May 20. [Class 119] Aiming practice for an automatic firearm without actual discharge of bullets is effected by observation of an intermittent light spot which is projected on to a moving target so as to lie in the line of sight, the light spot being continuously interrupted in accordance with the speed of firing. A machine gun 1 has a light source 5 and optical system 6 projecting a light spot on to a screen Z-Z on to which a moving target may be projected. A casing 2 on the machine gun houses a transformer 3 whose secondary winding 11 feeds a motor 7 driving a disc 12 having a slit 13 which traverses the light beam so that an intermittent light spot is projected on the target. The light source 5 and a hammer 14 actuated by ordinary electric bell mechanism to simulate the sound of firing, are in a circuit in parallel with the secondary winding 11, the light and hammer circuit being closed by a contact 9 when the trigger of the gun is pulled.

Title: An improved photometric instrument
Inventor: HAGNER BO ANDERS VILHELM
IPC: G01J1/04
Filed: 1967-11-10
Abstract: 1,241,549. Photo-electric measurement of luminance. B. A. V. HAGNER. Nov.8, 1968 [Nov.10, 1967], No.51204/67. Heading G1A. [Also in Division G2] In order to measure e.g. direct or reflected glare, an instrument is used which comprises a first photo-electric cell C 1  associated with an optical viewing system 2-6 which is directed at the glare-producing area, the cell C 1  measuring luminance within a small viewing angle of about 1 to 3 degrees, and a second photo-electric cell C 2  which is adapted for use externally of the instrument and measures illumination from a large viewing angle of between about 30 and 180 degrees. Only one of the photo-cells C 1  or C 2  can be coupled at any one time to a single moving coil meter 11 having two different scales and which is viewable externally or internally (through viewing eye-piece 6) of the instrument. The viewing system comprises objective 2, field lens 3, image rectifying lens 4, field lens 5 and eye-piece 6. The field lens 3 or lens 5 carries two mutually perpendicular scales calibrated in degrees to allow measurement of the solid angle being viewed. The field lens 3 also carries a mask defining an aperture 10, there being an equally-sized aperture 9 in mask 7 located before photo-cell C 1 . The photo-cell C 1  is connected through switch 22 when the viewing device is being used so that it operates the moving coil meter 11. Whilst viewing the deflection of pointer 14 on scale 17, calibrated in luminance units, can be read through a mirror 19 and the transparent part 18 of scale 15. The other scale 16, calibrated in units of illumination is used when the photo-cell C 2  is connected to the meter by switch 22. This photo-cell is normally housed within lid la of the casing and when in use is removed and placed at the observation point to measure the incident illumination. The measurement obtained may be converted to a luminance value by multiplying by a correction factor, in order to use it together with the luminance value from internally viewed scale 17 and the measured solid angle in calculation of the degree of glare from the source or area under investigation. Optical adaptors may be used with the photo-cell C 2  to measure smaller viewing angles than 180 degrees. Particular applications mentioned for the instrument besides glare measurement are measurement of illumination, reflection factors, light transmission factors, photographic exposure values &c.

Abstract: 1,204,563. Forging and stamping presses. H. BECHE. 11 Nov., 1968 [9 Nov., 1967; 17 May, 1968], No. 53250/68. Heading B3H. A forging or stamping press has its upper tup connected to a piston b actuated through oil in a pressure chamber in the piston by a drive weight d which dips into the oil and hydraulic lifting jacks K to raise the piston and weight to compress air in a cylinder f which accelerates the weight after release of the jacks. The weight has an upper piston head in the cylinder f and the air chamber g is supplied with compressed air through a valve h when the weight is uppermost. The weight is accelerated by the compressed air and at the end of the stroke the piston head enters an air buffer n. The buffer serves to recoil the weight. The movement of the weight is transmitted through the oil to move the tup, for example, at <SP>1</SP>/ 7  the weight speed. The press can be modified for slow working or drop forging by having a pair of outlet ports (o), (p), Fig. 2 (not shown), in the buffer. The ports are controlled by valves (q), (r). In one arrangement, Fig. 2, the valves are arranged to operate the press for dropforging and in the second arrangement, Fig. 3, the valves are arranged to operate for slow pressing.

Abstract: 1368815 Matrix displays OMRON TATEISI ELECTRONICS CO 23 Nov 1971 [25 Nov 1970] 54387/71 Heading G5C An indicia display system comprises a plurality of gas filled discharge tubes each having a cathode, a plurality of anodes arranged to display indicia and. a grid for controlling electron flow to the anodes, circuits for applying high potentials to selected anodes and to selected grids in response to two pulsed input signals and means for cutting off the beginnings and ends of the anode or grid pulses This prevents more than one digit appearing which would otherwise occur due to the pulses not being perfectly square. Corresponding anodes of each tube are connected in parallel Potentials corresponding to the row of digits to be displayed are successively applied to the anodes and potentials are applied sequentially to each grid to operate each tube only when the appropriate anode signal is applied Square wave generators S, U produce pulses in synchronization with clock pulses CP1 upon receipt of signals from a decoder of an electronic calculator The output from generator S passes via MOS transistors Q 11  ... Q 17 , to which clock pulses are applied, and transistors Q 21  ... Q 27  to transistors TRI ... TR7 which apply pulses to selected anodes by grounding these anodes which are normally at a negative potential. The output from generator U is connected together with timing pulses t 0  to gates A1 ... A3 whose outputs are connected to transistors Q 41  ... Q 43  via transistors Q 31  ... Q 33  to which clock pulses CP2 are also applied. The transistors Q 41  ... Q 43  operate transistors TR11 ... TR13 to apply sequential pulses to the grids. Clock pulses CP1, CP2 are of equal length but 180 degrees out of phase. Pulses t 0  are 3 clock pulses in width and in phase with CP2. The grid pulses are therefore ¥ the length of the anode pulses and because of the phase difference between CP1 and t 0  are centred with respect to the anode pulses i.e. a portion of both the front and rear of the grid pulses has been removed. In another embodiment the output from the generator S is applied directly to the anodes and pulses t 0  replaced by periodic signals from a counter.
