Title: Improvements in or relating to coal-cutting machines
IPC: E21C35/06
Filed: 1922-02-07
Abstract: 197,034. Moore, M. S. Feb. 7, 1922. Coal-cutting machines.-In a coal cutting machine provided with running wheels and a supporting skid, either of which may support the machine, the machine is hinged at one end to the skid and means such as jacks are provided for adjusting the machine relatively to the skid so as to bring the wheels into or out of engagement with the rails or ground. The cutter-bar machine shown is pivoted at 27 to a skid 24 and carries two pairs of wheels 5, 6 connected by chain and sprocket gearing. Manually-operated screw jacks 33 connect the rear of the machine to the skid: in lowering the machine, the front wheels 5 first contact with the rails &c. The rear-wheel axle may be driven from the motor shaft 13 through gears 14, 15, worm gearing 18, three pinions 19, 20, 12 of which the centre pinion 20 is slidable to permit disengagement, and bevel gearing 10. According to the Provisional Specification, the wheel-driving gear may comprise a bevel gear adapted to be clutched to a vertical driving shaft and driving one wheel axle through a horizontal shaft and bevel gearing.

Title: Improvements in or relating to change speed gearing
IPC: F16H61/02
Filed: 1949-02-10
Abstract: 679,473. Variable-speed gearing. M. & W. PATENTS, Ltd., and MILLER, A. A. May 9, 1950 [Feb. 10, 1949], No. 3681/49. Class 80 (ii). In a two-speed epicyclic gear in which the annulus 2 drives, the carrier 4 of planets 3 is driven, and the sun gear 1 either serves as a reaction member for a reduced drive or is clutched solid to the driving member for a direct drive the change is effected automatically in accordance with both torque and speed. Backward rotation of the reaction sun 1 is prevented a one-way brake 11, 12 and slight movement under the re-action torque acts through a screwthread connection 60 to control the engagement or disengagement of the direct drive clutch 53- 58 in conjunction with the effect of centrifugal masses 64 carried on member 55 secured for rotation with the sun gear 1. Thus at low torque the clutch 53-58 is engaged for direct drive and the masses 64 assist this engagement as the speed increases whilst when the torque increases the clutch slips and the centrifugal effect of the masses 64 decreases until the sun gear is held stationary by the one-way brake 11, 12. In another arrangement the clutch is radially acting and the centrifugal effect of the shoes themselves is utilised for engagement under control of a pin and cam slot connection with the reaction sun gear responsive to the reaction torque. A number of two-speed units as described may be arranged in series to operate in succession under different degrees of torque and speed. Specification 679,523 is referred to.

Abstract: 1,018,841. Laminates and laminating. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 21, 1963 [Jan. 31, 1962], No. 3690/62. Heading B5N. A thermoplastic sheet is bonded to a rigid or semi-rigid adhesively coated base layer, e.g. hardboard, with a layer of foam material, e.g. polyurethane, therebetween, by means of heated platens, the platen adjacent to the thermoplastic sheet having ribs surrounding patterned areas, so that during pressing the ribs compress the foam layer and bond the thermoplastic sheet to the adhesively-coated base whilst the patterned areas emboss the thermoplastic sheet. The platen may be of metal or of an organopolysiloxane elastomer with a metal surround, adjacent areas may carry different patterns, and the thermoplastic sheet, which may be a homopolymer or copolymer of vinyl or vinylidene or a copolymer or terpolymer of acrylonitrile, butadiene and styrene, may be formed from differently coloured sections welded together by the bonding operation referred to above. The base may be adhesively coated only in the areas of bonding.

Title: Data storing means
IPC: G06K7/14
Filed: 1974-01-26
Abstract: 1453139 Data store M TROTTA 26 Jan 1974 03750/74 Heading G4M Data, e.g. reference numbers of invalid credit cards, are stored on the radial surface of helical carriers 100. Each turn of each carrier is subdivided into 10 segments and each segment into 10 columns and each column contains 10 locations to that each turn represents 1000 locations which for the first turn represent the numbers 0-999. A mark in the appropriate location represents a credit card having that number as a reference number. The marks, which may be perforations in the carrier, are read by a head 30 which has two T-shaped sections 301, 302 one of which carries 10 photocells 303 and the other of which carries 10 bulbs. The second section 302 also has channels 308 through which pass elements 307 operated by solenoids 306 to perforate appropriate locations of the carrier. A motor 202 is used to rotate the shafts on which the carriers are mounted under the control of switches and relays. The required number is set up on a control panel (Fig. 11, not shown). Associated with the data carrier shafts are shafts 406 carrying cams 405 associated with the numbers. A switch is operated for the appropriate digit for each power of the number, e.g. a 3 in the ten thousand section of the number. This supplies a voltage on the appropriate one of lines 415 to the movable contact 407 of the appropriate relay 403-3. If shaft 406 and hence the data carrier 100 does not have the 30,000 section aligned with the read head then contact 407 engages contact 410 which is connected via adjacent relays on each side to motor 414 or motor 413. The cams on shaft 406 are evenly distributed around the shaft so that at any position of the shaft one relay 403 is open so that the voltage from contact 407 is only fed to one of the relays 413, 414 to rotate motor 202 in one direction. When the reading head reaches the appropriate section the contact of relay 403-3 is opened to supply the voltage to the thousand switches which feeds relays 503 via lines 515 in a similar manner. Similarly the hundred and the ten switches and relays are operated to align the desired column with the head and a brake is applied. Each coil 100 holds ten thousand numbers and the appropriate coil is selected using a hundred thousand selector switch. The appropriate photo-cell and bulb are selected using a units switch and a circuit is completed via a millions switch to operate a warning device (Fig. 8, not shown). The data may be recorded and read magnetically.

Title: Improvements in and relating to record card controlled tabulating machines
Filed: 1930-02-05
Abstract: 342,898. Statistical apparatus. REDFERN, C. A., 242, Heerengracht, Amsterdam. Feb. 5, 1930, No. 3855. Convention date, April 19, 1929. [Class 106 (i).] Totalling. - A record-card-controlled statistical machine has automatically operating mechanism which reduces vibration of moving parts of the machine by applying a holding or retarding force to said parts immediately they are released. The invention relates to the kind of machine described, for example, in Specification 26896/13, [Class 106 (i), Calculating &c.]. The adding sector a and type sector b are pivoted at c to the frame d. Connected to these sectors by a link g is a rod 1 bearing against a stop 2. Bearing on rod 1 is a cam 5 pivoted at 4 and having a spring 6 so that the cam tends to jam the rod 1 against stop 2 and hold the sectors. Normally, however, this cam is held off by a pin 8 linked to a rod 9, which has a member 10 controlled by link 12 and crank 13 on a shaft h which only moves at totalling. A rod 15 is continually reciprocated vertically from shaft i. Normally this action is ineffective, but at totalling the member 10 is moved into the path of 15 and rod 9 is raised to remove pin 8. Cam 5 then locks rod 1, thus preventing the sectors from flying back and causing shock. In Fig. 2 the pin-box (not shown) is reciprocated vertically by a cam on shaft j. This shaft also carries a cam 19 coacting with a roller 20 on lever 22 controlled by a spring 23. When the pin-box moves up, the springs on many of the reading pins are compressed by the pins meeting the unpunched parts of the cam. On the down stroke these springs are released and cause shock. The cam 19 is so shaped, however, that at this moment it extends the spring 23, this cushioning the pin-box. In Fig. 3 the main shaft k oscillates in known manner, whereby the sectors are restored to normal, as described in Specification 26896/13. This shaft carries a cam 24, of which parts O-II are straight and part II-III is curved. A roller 26, on a lever 25 pivoted to a fixed point p, is controlled by a link 28 and spring 27. When shaft k moves in direction A it brings the sectors to rest at normal position and the pressure of spring 27 counteracts the vibration due to the freeing of the sectors. Cam 24 is so shaped that the counter-pressure of spring 27 is greatest when the short sector springs e are freed (roller 26 on path O-I), and when the long sector springs f, Fig. 1, commence to be released (roller at point I) ; while with roller 26 at position 2 the stress due to freeing of springs f is reduced to zero. From cam points II-III there is no compensating action.

Title: Improvements relating to carburetting water gas with heavy oil
Inventor: HAWES JACK MALCOLM
IPC: C10J1/213
Filed: 1956-02-07
Abstract: 805,682. Water-gas plant. HUMPHREYS & GLASGOW Ltd. Jan. 11, 1957 [Feb. 7, 1956], No. 3874/56. Class 55 (1). In a process for the production of carburetted water gas, the blow phase is carried out in two stages in the first of which air is passed from a compressor 64 simultaneously through an inlet 12 of a generator 10 and an opening 28 of a carburetter 20, the blow gases emerging through outlet 16 and the heated air from the carburetter 20 mixing in a combustion chamber 36 and then passing in a divided stream partly through opening 56 to an air and steam preheater 48 and partly through a gas preheater 32. In the second stage of the blow phase air is passed up through the air and steam preheater 48, part of the pre-heated air then passing to the generator 10 through inlet 12 and part passing to the combustion chamber 36 to mix with the blow gases passing through outlet 16, the mixture being then divided so that one part flows through the carburetter 20 to reheat it and the other part passes through the gas preheater 32. The gases leaving the apparatus during both stages of the blow phase are passed through a waste heat boiler 58. After the blow phase, steam is fed from boiler 58 through inlet 50, up through the air and steam preheater 48 into the generator 10 at 12. The resulting blue water gas is passed from the outlet 16 down through both the gas preheater 32 and the carburetter 20 to purge them. In the make phase, the blue water gas passes up through the coal carbonization chamber 11, and the gas mixture leaving through the outlet 18 is passed up through the gas preheater 32 and down through the carburetter 20 into which oil is sprayed at 30. The carburetted gas is passed through wash-box 62. After the make phase steam is passed up through the air and steam preheater 48, and then down through the gas preheater 32 and the carburetter 20 to purge them. During all phases of the cycle other than the make phase, coal gas evolved in carbonization chamber 11 is passed through outlet 18 and wash-box 60 to treatment and storage.
