Title: Improvements relating to belt and like transmission gearing, also applicable to endless-belt and like conveyors
IPC: B65G23/12
Filed: 1939-08-26
Abstract: 534,269. Belt gearing. COOK, SONS & CO., (1930), Ltd., J., and HUNT, W. A. Aug. 26, 1939, No. 24594. [Class 80 (i)] An endless conveyer belt a passes around a drum b driven by an electric motor d and reduction gearing e contained within the drum. The belt also passes over a jockey pulley c. The stationary casing of the motor and the stationary element of the gearing are respectively attached to or integral with axle-like end members f, g about which the drum rotates. These members are received in supports h on side plates j slots r in which form guides for the spindle p of the jockey pulley. The ends of this spindle turn in bearings n in connecting rods m connected to cranks k fixed to the axle ends f, g. Torque reaction causes the cranks k to move angularly to a limited extent which movement causes the jockey pulley to press on the belt. In a modification, the electric motor is outside the drum b.

Title: Improvements in or relating to card-feeding apparatus
Inventor: PAVLIC IVO
IPC: G06K13/103
Filed: 1959-07-17
Abstract: 891,989. Feeding cards. INTERNATIONAL COMPUTERS & TABULATORS Ltd. June 2, 1960 [July 17, 1959], No. 24714/59. Class 117. Cards 1 are discharged from magazine 2 for use in a computer by picker 3 reciprocated by cam 46 on driving shaft 45, each card being fed into the nip of rollers 4, 5 provided with notches 6 to accommodate the leading edge of the card, and the rollers 4, 5 delivering the card on to one or other of platforms 7, 8 the choice of platform being made by distributer 10 operated by solenoid 12. The platforms constitute a waiting station. The cards on platforms 7, 8 are tamped into predetermined position by tapper 15 and are selectively discharged therefrom towards the computer by pushers 19 or 20 operated by respective solenoids 25 or 26. Interrupting discharge of magazine 2. Cards 1 in magazine 2 rest on leaf springs 29. These are elevated by pins 33 to interrupt the card discharge; the pins being raised by the driving shaft 45 operating via eccentric 44, bellcrank 40 and stem 36. As shown, the pins are raised every time the picker 3 moves forward, being operated by the common driving shaft 45, so that no discharge takes place although picker 3 reciprocates. When, however, solenoid 49 is operated, armature 48 displaces interposer 47 to the right to permit stems 36 to fall into slots 53. This allows lost motion between bellcrank 40 and stem 36. The pins 33, therefore, do not rise, and the picker 3 discharges the cards normally. Operation. When the computer signals that it needs a card, it operates solenoid 25 or 26, solenoid 12 and solenoid 49. This causes: pusher 19 (or 20) to discharge a card from platform 7 (or 8) towards the computer; pins 33 to drop to allow picker 3 to discharge a card from the magazine 2; and distributer 10 to guide the card from the magazine to the platform which is now empty. In this way the movement of the computer is separated and free from the cycle of the picker 3. Specification 842,810 is referred to.

Title: A process for the production of cellulose fatty acid esters
IPC: C08B3/00
Filed: 1929-08-15
Abstract: 336,349. Werner, K. Aug. 15, 1929. Cellulose carboxylates. - In the production of cellulose fatty acid esters by a process wherein water is removed from air-dried cellulose prior to esterification by treatment at temperatures up to 50‹ C. with a quantity of fatty acid and fatty acid anhydride sufficient to complete the esterification reaction, removal of water is effected in the presence of a small quantity of catalyst insufficient to promote esterification, e.g. 0.02-0.05 per cent sulphuric acid or 0.05 per cent sulphuryl chloride calculated on the weight of the cellulose. Diffusion of the pretreating liquid through the cellulose is preferably effected by a milling process, e.g. in an edge, roller or ball mill. After pretreatment, esterification is carried out by successive additions of catalyst, preferably a weak catalyst such as sulphuryl chloride, thionyl chloride or phosphorous oxychloride, suitably in a rotating drum, the temperature being allowed to rise gradually to 60-70‹ C. until esterification is complete. Excess of anhydride is then destroyed by addition of acid and the catalyst is neutralized by appropriate addition of sodium acetate. In an example, 700 kg. of air dried cotton linters, 1800 kg. acetic anhydride, 2700 kg. glacial acetic acid and 0.14 kg. sulphuric acid are subjected to intensive mixing in a roller or ball mill; after 24-36 hours, 500, 800 or 1200 grammes of sulphuryl chloride in about 25 kg. of a 40-60 mixture of acetic anhydride and glacial acetic acid is added, little by little, during 8-10 hours, the temperature slowly rising to 60-70‹ C. The acetate finally passes into a clear, viscous solution. In place of sulphuryl chloride, corresponding quantities of thionyl chloride or phosphorus oxychloride may be used. Propionic and butyric anhydrides and acids and mixed anhydrides are included in further examples. Specifications 332,607 and 332,608 are referred to.

Abstract: 580,676. Galvanic batteries. BURNDEPT, Ltd., and RICHARDSON, R. P. Dec. 13, 1944, Nos. 25016/44 and 3827/45. [Class 53] The casing of an inert dry battery consists of a moulding of a plastic material such as a phenolic synthetic resin having compartments for the separate cells, each compartment being provided for the admission of water with one or more openings which extend through the material to the surface of the moulding and may be in or near the lower ends of the compartments. The battery may be a high-tension battery for use in a portable wireless apparatus and where a low-tension battery is also required 'this may be built into a similar plastic moulding which may be fitted to the casing of the high-tension battery. Fig. 8 'shows a high-tension and a lowtension battery fitted together in which the high-tension battery comprises a moulded casing 1 having compartments of cylindrical or other shape each of which is provided with one or more filling openings 11 in the bottom. A projection 9 on the base of each compartment supports the dolly of the' cell, the negative electrode consisting of a zinc sheet 8 bent into cylindrical form and resting on a ledge 7 formed on the wall of the compartment. A ledge near the top supports a closing disc 6 above which is a sealing of bitumen &c., 37. After the battery has been filled with water the openings 11 are closed by a wax filling and a waterproof tape 13. Connecting sockets may be moulded into the plastic casing or they may be moulded into a separate insulating body 24 accommodated in a compartment 18 as shown in Fig. 7. The body 24 is secured in place by screws 22 and the sockets 21 project through-openings 19 in thecasing 1. Until the battery'is required'for use the sockets are covered by a rubber disc 25 pressed down by a screw 23. A low-tension battery comprises a plastic moulding 26 having two sets of cell compartments opening at opposite ends of the moulding the filling passages being brought out to one of the larger faces'of the casing. The compartments contain battery elements similar to those of the high-tension battery and the casing fits within the rim of the high-tension battery casing, the two batteries being secured together by screwed studs and nuts 31 and protected by steel casings 34 sealed by waterproof tape 35. Cardboard packing sheets 36 ensure a tight fit of the batteries in the casings.

Abstract: 1,262,877. Selective signalling. SONY CORP. 16 May, 1969 [17 May, 1968], No. 25030/69. Heading G4H. a position measuring system of the type in which a phase significant signal is produced by quadrature spaced heads 103, 104, Fig. 3, sensing a uniform non-coded scale 101, the phase significant signal is converted 110 to pulse form and applied to the "set" input of a trigger 112, while reference pulses of frequency mF, where F is the frequency of the phase significant pulses, are applied to the "reset" input of the trigger, so that in each cycle of the phase significant signal a pulse is produced by the trigger extending from the occurrence of a pulse of the phase significant signal to the next reference pulse, and this duration, which represents the unknown position within a sub-cycle equal to 1/mth of a cycle of the phase significant signal, is used to gate 119 relative high frequency clockpulses to a counter 121. Thus in effect one cycle of the phase significant signal from the reading is divided into m sub-cycles by the use of reference pulses of frequency mF-which is equivalent to subdividing the actual scale 101 by a factor of m-and the counter 121 determines position within a sub-cycle.
