Patent GB-1070687-A (GB)
Title: Data collection and storage system
IPC: G06F13/22
Filed: 1965-08-10
Abstract: 1,070,687. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 10, 1965 [Nov. 9, 1964], No. 34120/65. Heading G4H. A sampled value is stored if the difference between it and a reference value exceeds a certain limit, the limit being increased if the capacity of the store would otherwise be exceeded. Analogue input channels (12) are sampled in turn, one per millisecond, by a first counter (42, 44), the analogue data values being digitized (26) and then stored in a register (28) together with the channel identity and the time in the form of a number of milliseconds since the last full second, the channel identity and time coming from the counter. In each case, the channel identity is also used to address a reference store (18) to obtain a reference value and limit. The data value is subtracted serially (74) from the reference value and the result used to preset a second counter (94). The limit is used to preset a third counter (88). The second counter (94) is incremented or decremented according to the presence or absence of a borrow from the subtractor, and the third counter (88) is decremented in synchronism. When the third counter reaches zero, pulses are cut off from both second and third counters, but if prior to this the second counter reaches zero, a flip-flop (130) is reset. If the flip-flop remains set, the contents of the register (28) are stored in the next available address in a main store (16), and the data value from the register replaces the reference value in the reference store. If the main store fills too quickly as determined by comparing (30) the current main store address with the time from the first counter, the limit is widened by forcing all ones into the third counter (88) until compensation has occurred. The time in the form of the number of full seconds from the first counter is stored in the main memory every second. A parallel digital input channel (14) may seize the system at any time. Two main stores may be used alternately, the one not in use for storing feeding a magnetic tape unit. The widened limit may be variable and some channels may be exempt from it.

Title: Improvements in or relating to photographic camera shutters
IPC: G03B7/12
Filed: 1955-12-02
Abstract: 802,020. Photo-electric control arrangements. GAUTHIER G.m.b.H., A. Dec. 2, 1955 [Dec. 23, 1954], No. 34595/55. Class 40 (3). A photographic shutter is provided with a photo-electric exposure control mechanism including a lever system which senses the position of the movable part of the meter mechanism from two opposing sides. This arrangement operates effectively and exerts no turning moment on the meter mechanism even when the pivot shaft of the latter is resiliently mounted for the purpose of safeguarding it against shock. In one embodiment the meter shaft carries two corresponding cam surfaces 8b, the position of each of which is felt by the arms 9b, 10a, of levers 9 and 10 pivoted respectively at 11 and 12. The opposite ends of the two levers co-operate with each other by means of slot 9a and pin 13. A. slot in the arm 10a and a pin on the end of one arm (not shown) of lever 17 (Fig. 3), transforms the meter information into a positioning of the stop 17c on the end of arm 17b of lever 17. A light spring 18 associated with lever 17 maintains the arms 9b, 10a, against the control cams 8b. The stop 17c abuts against one or other of the steps 19a on setting ring 19, the pressure of the ring against the stop producing no, or only a small clockwise, turning moment on the lever 17. The ring 19 is arranged to be adjustable on exposure setting member 20 by means of handle 19c which may be positioned, for example, in accordance with the speed of the film in use as indicated on the co-operating scale. So that the meter moment may be completely free to move the exposure setting member may include an abutment which strikes against pin 13 in its initial position and lifts the lever arms 9b and 10a from the cams 8b. A detent device holds the setting member, when set, against the tension of a spring 4. The latching of the setting member is released by depressing button 7 and the member then returns to its initial position.

Title: Means for moving a member linearly
Inventor: SAUNDERS CHARLES WILLIAM THOMA
IPC: F16K31/05
Filed: 1964-08-26
Abstract: 1,039,195. Valves; converting rotary into reciprocating motion. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 28, 1965 [Aug. 26, 1964], No. 34915/64. Headings F2Q and F2V. Linear movement of a valve closure member 3 may be effected by a hand wheel 6 or a reversible electric motor 9 on a bracket 8 fixed to the valve body. A motor pinion 11 meshes with a ring gear 12 clamped between two plates 13 which mount three planet gears 14, the upper halves 15 meshing with a first sun-gear 16 threadedly engaging a screwed part 18 of the valve stem 4; the lower parts 19 of the planets engage a second sun-gear 20 threaded 21 on to an element 23 fixed to the bracket 8 and having a thread of opposite hand to that of the first sun-gear 16. The latter has one less tooth than the second sun gear. With the motor inoperative the sun gear 16, 20 are prevented from rotating so that the valve may be actuated directly from the hand wheel through the threads 17, 18 on the first sun gear and stem, respectively. Energization of the motor 9 rotates the ring gear 12 and since the stem 4 tends to remain stationary when the member 3 is jammed on to its seat the sun gear 16 also remains stationary and the planets 14 will be rotated. Due to the ratio difference between the planets 14 and the sun gear 16, 20, the latter will be slowly rotated and apply a high torque to the element 23, the resulting high force relative axial motion of the sun gear 20 lifting the stem 4 until the sun gear abuts a shoulder 27 on the element 23 whereupon its rotation is also stopped. The planets 14 now roll round the sun gear 20 and torque of a lower value is applied to the first sun gear 16 to continue the upward motion of the stem with reduced force. A similar cycle of events occur during closing of the valve. A packing 5 round the stem or a removable tooth which constrains the stem 4 for linear movement during power operation must be overcome or removed upon manual actuation.

Abstract: 972, 248. Fault testing; bridge circuits. WALTER KIDDE CO. Ltd. Sent. 28, 1962 [Sept. 28. 1961]. No. 34938/61. Heading G1U. [Also in Division G4] A fire detection system of the type having a normally closed detector circuit including one or more fusible links 3, each link having a small fixed resistance 4 connected in parallel with it, has the fire detector circuit connected as one arm of a Wheatstone bridge the balance detector of which consists of a sensitive moving coil relay 10 whose contacts are open when the bridge is balanced. If the balance is disturbed, however, the contacts close to energize a relay F1 which operates to move the contact F2 to the position F3. If the unbalance is due to a fire, when only the fusible link 3 has been destroyed, a circuit is made through a relay G1, operating the switch G2 to give a fire indication on the lamps 11. This also actuates a relay E1, which operates to switch the contact E2 to the position E3 to de-energize the relay F1 while leaving G1 and the fire indicator lamps 11 energized. In the event of the bridge unbalance being due to an open circuit fault in the detector circuit the relay G1 will not be initially energized, so that the relay E1 will not operate. This means that the relay F1 will remain energized, closing the contacts F4 and lighting the fault indicator lamps 12. Specification 780,194 is referred to.

Title: Improvements in and relating to film projectors
IPC: G03B21/43
Filed: 1969-07-11
Abstract: 1,210,907. Cine projection apparatus. RICOH K. K. July 11, 1969 [July 17, 1968], No.34971/69. Heading G2E. A cine projector taking films in cassettes 1 comprises a spring-loaded locking latch 3 which enters recess 1b of an inserted cassette until disengaged at the end of the films run by arm 6b of a bellcrank 6 which is displaced by a signal rod 8 extending from cassette I and moving in response to the amount of film remaining, the cassette then being displaced by spring-urged push rods 4 to a withdrawal position. Depression of "Play" button 14 starts the projector motor and engages a clutch 20 with the takeup spool in the cassette by shifting the driven clutch shaft 17 by means of spring-loaded lever 24 and bell-crank 22. Hook 12a on spring-loaded member 12 holds button 14 depressed by engaging extension 14a. Depression of "Off" button 16 cams member 12 to the right and releases the "Play" button, stopping the motor and disengaging clutch 20. Further depression of button 16 raises arm 9b of the release rod 9 by means of a lever (27), Fig. 2 (not shown), and rotates bell-crank 6 anti-clockwise to disengage latch 3 from the cassette 1. Push-rods 4 then extend the cassetts for withdrawal or rewind. Depression of "Rewind" button 15 re-starts the motor and causes a driven clutch (34), Fig.3 (not shown), to enter aperture 1f to drive the supply reel, the lever linkage being similar to that described for clutch 20. Button 15 is also held down by a hook on member 12 until the "Off" button is depressed.

Title: Method of separating the poisonous constituents of tobacco smoke
IPC: A24D3/16
Filed: 1929-11-19
Abstract: 338,006. Põffgen, H. Nov. 19, 1929 Tobacco; tobacco pipes &c.-The poisonous constituents of tobacco smoke, such as nicotine, pyridine, and " brenzole," are separated by passing the smoke through a dry absorption medium, such as highly activated carbon or silica gel, which has been previously saturated with a volatile substance adapted to prevent the aroma-imparting constituents from being absorbed also. The preliminary treatment of the medium is effected by the smoke obtained from the combustion of nicotine-free tobacco waste, or by etheric oils such as peppermint oil, or by incorporating with the medium, during its production, sodium hydroxide, sodium carbonate, cane sugar, common salt, tannic or barbituric acid, ozone, or sodium hydrosulphite. In the case of silica gel, the preliminary treatment may consist merely in stopping the drying process when the water content is 20-25 per cent. When etheric oils are used, they are dissolved in alcohol, ether, &c., and the solvent driven off by heat or by conducting air therethrough.

Title: Improvements in core blowing apparatus
IPC: B22C15/24
Filed: 1955-12-09
Abstract: 781,147. Core-making machines. NEWBY, R. L. (Dodge Steel Co.). Dec. 9, 1955, No. 35371/55. Class 83 (1). A core-blower comprises a foraminous member through which sand is discharged into a core-box, and a gasket of sheet material covering the formainous area of the member and having a ported area in registration with one or more holes of said member registered with corebox cavity, the gasket closing those of the holes of the member not registered with the cavity or not required for the blowing operation, the gasket being retained in operative position with respect to said member by readily releasable means. The machine comprises a hopper 8 movable by a cylinder 15 between a position registering with a supply hopper 12, and a position registering with a pressure-fluid supply fitting 18 and above the core-box support 22, which is vertically reciprocable by a piston 21. A false-bottom structure 26 comprises spaced plates 27, 28 having aligned holes 31, 32 which, in the operative position of the structure, align with holes 29 in the perforated bottom 10 of the hopper 8. Additional holes 33 in the lower plate 28 communicate with the chamber 35 formed between the plates 27, 28, while the holes 31, 32 are connected by nipples 36 so as to form passages through said chamber from the underside of plate 28 to the upper side of plate 27, the upper end of said passages registering with the holes 29 when the plate structure is clamped to the bottom wall of the hopper by wedges 42 passing through slotted pins. The structure may be moved to the inoperative position, shown dotted in Fig. 2, on wheels 49. In operation, sand is blown into the core-box through the nipples 36, while displaced air is vented through the holes 33, into which are placed cup-shaped strainers 53. Alternatively, mesh-screening is incorporated in the plate 28. In order that the apertures 29 and registering nipples 36 which are not in communication with the core-box cavity or closed by the confronting surfaces of the core-box, may be sealed, a gasket 54, Fig. 13, is interposed between the hopper wall 10 and the plate structure 26, and provided with apertures 56 which register with the openings 29 which, through the nipples 36, communicate with the core-box cavity. Since the pattern of holes 56 will vary with different core boxes, the gasket is initially formed with a series of cored circles 59, corresponding in number and disposition with the holes 29 in the hopper bottom, and also with a pattern of etched circles on a transparent template 57, Fig. 12. The circles on the template are individually identifiable, and when the template is placed on the core box the position of the holes which should be made in the gasket 54 may be seen. The gasket may be of Kraft paper.
