Title: Rotating impeller gas-meter
IPC: G01F15/00
Filed: 1951-03-22
Abstract: 686,144. Rotary meters. AERZENER MASCHINENFABRIK GES. March 22, 1951 [March 27, 1950], No. 6876/51. Class 110(ii) [Also in Group XXIX] A rotating impeller gas-meter of the " Rootsblower " type has a device for continuously changing the lubricating oil in the bearings and gear drives of the meter to protect these parts from attack by impurities in the gas. A pump 7, driven either from one of the impeller shafts or independently of the meter, draws oil from the upper part of a tank 8 and delivers it to the gearing 4 and bearings 3 through pipe lines 7a the outlets from which are constructed to deliver the oil in the form of a spray. A pipe 7b returns the oil to the lower part of the tank 8 where the impurities settle out. An inspection window 15 shows when the impurities have raised the level of the oil sufficiently to necessitate re-filling of the tank which is provided with a drain cock 16 and a filler at the top for this purpose Cocks 17 and 18 are closed during refilling. Windows 14 and 13 show the normal level of oil and allow the degree of pollution to be ascertained. The lubricated parts are housed in chambers 5, 6 separated from the measuring. chamber 2b by packing elements 10, such as splash rings, and by chambers 11 which collect easily condensed vapours from the gas and any oil which leaks through the packing elements.

Title: Single-rail insulated track circuits in railway equipment
IPC: B61L1/18
Filed: 1962-02-22
Abstract: 990,556. Track circuits. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. (STIN). Feb. 22, 1962 [April 1, 1961], No. 6889/62. Heading B7N. In a single rail track circuit arrangement, a track occupied condition is signalled by one of two adjacent circuits in the event of breakdown of the insulated joint between the circuits. The circuit current feed arrangement includes changeover means whereby adjacent circuits are alternately energized. The receive circuit includes a saturable transformer 2 comprising a winding 24 fed by the supply current, a winding 22 connected in series with a track relay 41 across the receive terminals A, B, a winding 21 supplied with alternating current from high impedance source 1 and a winding 23 which supplies a relay 32 via a rectifier 31. During the period the circuit is energized and its track section is free, the received current in winding 22 energizes relay 41 and with the current in winding 24 saturates the transformer so that the transfer of energy from source 1 to relay 32 is cut off. During the period the circuit is deenergized relay 32 is energized from source 1. The value of condensers 33, 42 is such that the associated relays 32, 41 are maintained energized during their respective periods of non- energization. In the event that the insulated joint between the adjacent circuits breaks down, winding 22 is continuously supplied with current, the transformer is continuously saturated and relay 32 releases and indicates track occupation.

Title: Printing apparatus
IPC: G06K15/12
Filed: 1975-02-19
Abstract: 1459717 Printers INTERNATIONAL BUSINESS MACHINES CORP 19 Feb 1975 [22 March 1974] 6919/75 Heading G4H In printing apparatus for generating characters by scanning a surface with a modulated beam, binary words representing the sequence of modulation of the beam are derived from a font memory in accordance with the characters to be printed, and stored in a set of N shift registers, the first N bits of a word being stored in the first stages of the N registers respectively, the next N bits in the second stages &c., the first stages being read out in sequence to control the beam, and the other stages being shifted along, the first register to be cleared then receiving the first, (N+ 1)th, &c. bits of a further word in its first, second &c. stages, subsequent cleared registers receiving other bits of the further word correspondingly. Successive words are thus contiguous on read out, even though they are not necessarily of the same length and different fonts using different lengths of word can be handled. The font memory holds data for the matrix decomposition of all characters in various fonts including a rotated font. The latter refers to the capacity of the system to print the page with the lines of characters running axially or circumferentially relative to a rotating copy drum which is scanned axially by a laser beam (for xerographic printing) to build up the page of characters. As disclosed, two binary words from (or derived from) the font memory are needed for each scan line in each character, and the lengths of them are modified in accordance with the font (or are already stored in modified form in the font memory) prior to routing to the appropriate stages of the N (as disclosed, 8) shift registers. The register to receive the first bit of a word is obtained as the remainder on dividing by 8 the sum of the number of the register for the first bit of the previous word and the length of the current word (derived from font bits), this remainder controlling input routing gates for the shift registers and a ring counter. The quotient from the division is loaded into a decrementable counter, detection of zero in which provides direct and delayed enable signals to stages of the ring counter. The ring counter is also clocked by signals derived by counters driven via a scale and photodetector by movement of the laser beam. The ring counter provides load and shift control signals to the various shift registers. Since all the binary words have in fact got an even number of bits, the shift registers are controlled in pairs, the ring counter having four stages.

Abstract: 1,081,911. Moulding void-free glass reinforced resin. ENGLISH ELECTRIC CO. Ltd. May 17, 1965 [Feb. 19, 1964], No. 6978/64. Heading B6A. A bubble-free reinforced plastics article is moulded from a layer 12 of glass fibre, covered with epoxy or polyester resin, in a mould base 11 covered by an imperforate flexible, e.g. rubber, membrane 13 within an autoclave 15; the autoclave 15 is depressurized, e.g. by a vacuum pump connected at 16 preferably to a lower pressure than the space between the mould 11 and membrane 13, to release bubbles entrapped by the membrane, which space is simultaneously evacuated of air and vapours formed during the polymerization process, via outlet 14, whilst the temperature is increased, e.g. to 60‹ C. by radiant heaters 17, to below the resin curing temperature to facilitate resin flow through the reinforcement. The lower pressure in the mould 11 is maintained whilst the autoclave temperature and pressure are raised, e.g. to 22 p.s.i. and 130‹ C., by the introduction of wet steam via pipe 18 to complete the cure. The autoclave pressure may also further be increased by the introduction of air whilst maintaining the temperature of 130‹ C.

Title: Improved control mechanism for change-speed gearing
Inventor: ACRES FREDERICK ALBERT STEPNEY
IPC: F16H63/44
Filed: 1950-03-23
Abstract: 688,842. Controlling change-speed gearing. VAUXHALL MOTORS, Ltd. March 22, 1951 [March 23, 1950], No. 7253/50. Class 80 (ii). Controlling mechanism for a motor vehicle change speed gear is actuated by a lever 30 moved transversely and longitudinally in an H- gate 33 and also moved lengthwise through the gate when in its centre or neutral position, this lengthwise movement providing an additional change of speed so that two ratios can be selected for each position of the lever 30 in its gate. The change speed gear gives six forward and two reverse ratios, as described in Specification 688,841, and comprises parallel driving, intermediate and driven shafts 10, 11, 12, Fig. 1, fast gears 13, 15, 17, 19, 21, loose gears 14, 16, 18, 20, 22 and clutches 23, 24, 25 which selectively couple the loose gears to their respective shafts for the forward ratios. Reverse is provided through gears 26, 27. The controlling mechanism for the gear is operated by the lever 30, slidable in a ball 31, passing through the opening formed by two jaws 35, 36 on selector bars 37, 38 having a sliding interlock 42, the first selector bar actuating clutch 24 through a fork 39, and the second actuating clutch 23 through a fork 40, and the reverse gears 26 through a fork 41. The lever 30 has a pivoted and sliding connection through members 50 to 55 with another selector bar 45, having a lostmotion connection 69 with a lever 67 and a fork 68 actuating the clutch 25. The selector bar 45 also has cam and valve means 46, 60, 61 which control the flow of compressed air or the like to servo means such as 63, 65 normally actuating the clutch 25 through levers 66, 67 &c., the construction being such that should the servo means fail, the clutch 25 is moved mechanically. The reverse gears 27 are similarly normally operated by a servo device having a separate valve. The clutch 25 is engaged with either of the loose gears 20, 22 by vertical movement of the control lever 30, which has a protuberance 34 able to pass through the H-gate 33 only when the control lever is in its central or neutral position, viz. when the clutches 23, 24 are disengaged. A ball-and-slot connection 70, 71, 72 on the selector rod 38 allows the reverse gears 27 to be engaged with gears 26 &c. without moving fork 40, controlling clutch 23, further than is necessary to disengage the clutch, the ball 70 being allowed to ride out of its slot after this initial movement, and thus permit the fork 40 to slide on the bar 38. A shaft 75 for an optional front wheel drive may be coupled to the driven shaft 12 by a servo-actuated dog clutch 76.

Title: Exposure control system for a photographic camera or shutter
IPC: G03B7/083
Filed: 1968-02-14
Abstract: 1,215,533. Exposure control. HATTORI TOKEITEN K.K. Feb. 14, 1968 [Feb. 14, 1967], No.7308/68. Heading G2A. A shutter mechanism includes an electrical circuit which first assesses whether or not the scene brightness is sufficient for a satisfactory exposure, and then, if so, acts as an automatic exposure control means. As shown, a release slide 1 can move downwards, against a spring 6, to effect the shutter release. A closing lever 14, pivoted on a shaft 11, is spring-biased so that a pin 15 thereon bears against a profiled section of the edge of slide 1. One end 43 of lever 14 can abut the core 34 of an electromagnet 33, and a pin 35 at its other end can engage an intermediate lever 38. A further lever 47 is spring-biased into latching engagement with an abutment 44 on the shutter-driving ring 40, so holding it in the tensioned position shown. As soon as slide 1 starts to move, a switch S, is closed, so connecting a power supply (60), Fig. 2 (not shown) into circuit. This is a trigger circuit having two transistors (66, 67) in a bi-stable vibrator arrangement. The acceptable brightness level is set by a variable resistor (63). If the brightness, as detected by a photo-resistor 61, is insufficient, the electromagnet 33 is energized, and lever 14 is held against it in the position shown in Fig.1. Lever 38 is thus pivoted clockwise against spring 37, and another lever 48 on the same pivot 36 takes up the position shown, in which a hooked end 50 engages a projection 25 at the lower end of slide 1 and prevents it from moving any further. Thus the shutter is not released. If the detected brightness is above the acceptable level, the electromagnet is not energized, so that lever 14 is free to move. As pin 15 follows the profiled edge 26, 27, lever 14 pivots clockwise, allowing levers 38, 48 to pivot anti-clockwise. Thus hook 50 moves out of the path of slide 1, allowing the latter to continue moving downwards. This allows a lever 21, engaging with a profiled edge 17, 17<SP>1</SP>, to move a changeover switch S 2  which shunts a capacitor (62) into the circuit, this now acting to control the exposure time according to the light received by the photo-cell 61. Further downward movement of slide 1 causes a pin 24 thereon to engage lever 47 and rotate it out of engagement with abutment 44, so allowing ring 40 to rotate and open the shutter blades. At the same time a switch S 3  is opened, allowing the capacitor to charge. After a time delay, the previously re-energized electromagnet is de-energized once more, releasing lever 14 to rotate clockwise. Face 43 of lever 14 now strikes a pin 41 on ring 40 to rotate it in the reverse direction, so closing the shutter to terminate the exposure.
