Patent GB-133097-A (GB)
IPC: G06C27/00
Abstract: 133,097. Dehn, F. B., (Automatic Bookkeeping Register Co.). Feb. 27, 1918. Cash registers; cash-drawer mechanism. - A cash register is provided with a series of trays to contain account slips for the various customers. The trays are normally locked in the closed position, but, on depression of a clerk's key to free the operating-mechanism the trays are released to enable the clerk to pull out the necessary tray and insert in it the new' sales slip after entering upon it the customer's new debit. A cash drawer release is set for actuation by the main operation of the machine whenever a cash transaction key is depressed. The cash-register is provided with the usual key-board containing keys for the various transactions, the customers' numbers, the clerks, and the money amounts concerned. The registering wheels are seen at 25 and the cash drawer at 14. Surmounting the machine is a casing 2 containing a series of bins 473, Fig. 7, each in turn enclosing a number of sliding trays divided into compartments 480 corresponding with the customers. The bins are normally locked in the casing 2, by means of pivoted hooks 491 engaging pins 484. The release of all the bins may be effected by the handle 500 accessible only through the proprietor's door 19. Each tray compartment 480 has a spring lid 481 held down by a finger latch and contains all the account slips appertaining to the particular customer concerned. Each tray is linked to a pair of scissorarms 504 mounted in juxtaposition to vertical bars 515, 516 carried by spindles 511, 512. When a clerk's key is depressed it produces a forward movement of a rack 523, Fig. 5, and a consequent rocking of the shaft 42. This in turn releases a bell-hammer lever 534 through an arm 540 and a notched slide 527 and also a pivoted arm 519, Fig. 8, connected with the spindles 511, 512, thereby enabling these to turn and the trays to be pulled forward by the clerk. When the main shaft 21 is operated, a countershaft 43 is rocked and, through a slotted bar 556, returns the arm 519 to normal position. This causes the bars 515, 516 to move forward and by actuating the scissor arms 504 to close any trays that may have been opened. The spring-controlled cash drawer 14 has a latch 445 pivoted to a vertical bar 448 the upper end of which is pushed to the rear by the rocking of a lever 460 whenever a cash transaction key is depressed. This rearward displacement brings the bar 448 within the reach of a collar on the countershaft 43 so that, when this is rocked in the operation of the machine, the bar 448 is depressed and the drawer released. The main operating shaft 21 is normally locked against rotation by means of a hook 552 engaging a crank-pin 98 and connected with the shaft 42 rocked, as above described, by the depression of a clerk's key.

Inventor: BAKER GEORGE THOMAS
IPC: H04Q3/42
Filed: 1953-05-21
Abstract: 723,147. Automatic-exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. May 21, 1953 [May 27, 1952], No. 13433/52. Class 40 (4). In a high-speed storage device of the magnetic drum type such as is described in Specification 717,689, economy is effected by having one set of signal-receiving apparatus fed successively by a number of reading heads. The time relationship of pulses TZ1-TZ20, individual to the subscribers' lines associated with one track, is shown in Fig. 2, which also shows the time relationship of pulses TW1-TW6 corresponding to successive revolutions of the drum. In the first revolution, pulse TW1 biases rectifiers MR1, MR2 so that reading head RH1, associated with the first track feeds amplifier A and -pulse-generator PG, of the type described in Specification 723,146, [Group XL (c)], to feed reading off equipment RE. Pulse TW1 also biases rectifiers MR3, MR4 so that the output of RE is fed to the terminal O1 corresponding to the first track. Similarly pulses TW2-TW6 connect RH2-RH6 through the common circuit A, PG, RE to output terminals O2-O6 in subsequent cycles.

Title: Improvements in traps for animals
IPC: A01M23/26
Filed: 1921-05-12
Abstract: 181,925. Willcutt, H. W. May 12, 1921. Animal traps.-A spring-jaw trap is held open by a catch 28 which holds together one of the jaws 10 and a hinged bail 15. The catch and a trigger 32 by which it is released are not connected to the other parts of the trap but are carried freely by an anchoring-chain 38. The opposite ends of the jaws 10 are pivoted in links 11. Each link is surrounded by a spring 23, which abuts at the top and bottom respectively against telescoping housing sections 18, 17. These parts are held together by a pin or key 16 which is passed through the bifurcated reduced end of the link 11 and through the corresponding end of the bail 15, so as to form a pivot for the bail. The pin is normally drawn into a recess in a boss 24 on the lower end of the housing section 17, and maintained there by the force of the spring secure against accidental dislodgment, but it can be withdrawn by hand after overcoming the pressure of the spring. When the trigger 32 releases the catch, the sections 18 rise around the ends of the jaws, as the jaws close, until the sections engage enlarged portions 27 formed on the undersides of the jaws. The trigger 32 is slotted for the reception of the catch 28 and provided with a transverse pin 34 which works in an arcuate slot in the catch. A modified form of trigger mechanism is shown in Fig. 5. The jaw 10 and bail 15 are held together in a bifurcated portion of a retaining-device 50, until the nose of a catch 52 is released from engagement with a lip on the trigger 55.

Title: Improvements in and relating to the production of sand cores for foundry purposes
IPC: B22C1/24
Filed: 1940-08-27
Abstract: 543,202. Core materials. NICOLSON, J. Aug. 27, 1940, No. 13524. [Class 83 (i)] Core material, stated to retain its plasticity for rammed or blown cores over long periods, comprises sand, oil, borax, and the product obtained from starch containing protein by thinning and partly cooking or gelatinising. A water suspension of 30-35 per cent maize, 2-15 per cent protein content may be heated to 50‹ C., hydrochloric acid added until 10 ccs. of the filtered liquid will neutralize 14-16 ccs. of deci-normal sodium hydrate solution. Heating is continued for 15-20 hours while agitating. Tests are made meanwhile, by the Scott method of estimating fluidity, on 65 grams of the starch, neutralized and dried, mixed with 280 c.c.s. of water. When a fluidity of between 40-50 is reached heating is stopped and the starch neutralized to pH 6-6.8 with soda ash. Ten to 15 per cent of borax, calculated on dry starch, is then added to the starch suspension which is partly cooked, dried on film-drying cylinders, ground to pass a 30 mesh sieve, and mixed with core oil, a suitable oil being 50 parts linseed, 30 rosin oil, and 20 bitumen. Alternatively the borax is added with the oil after drying. In a modification the dextrine process may be used for thinning. If bitumen is omitted, anti-oxidants, such as phenol-betanaphthol, hydroquinone, or pyrogallol, or antiseptics, such as formaldehyde or cresol, or both, may be added to prevent hardening and rancidity. Specification 515,470 is referred to.

Abstract: 764,495. Dynamo-electric machines including magnetic couptings. JARRET, J. H., and JARRET, J. M. B. May 10, 1954 [May 12, 1953; April 30, 1954], No. 13609/54. Class 35. Relates to machines such as reciprocating inductor alternators and magnetic couplings, preferably with a moving member or members direct-coupled to engine pistons. As shown in Fig. 1, flux through the rotor 17 carrying a winding connected to short-circuited brushes is reversed as inductors 14a, 14b are reciprocated in their slots in the stator core by the piston 6 of an I.C. engine, thereby causing rotor 17 to rotate at a speed dependent on the position of the brushes. The stator carries exciting coils 15a, 15b or can be permanently magnetized. The engine cylinder may have a second piston for operating a second machine. In Fig. 3, coils 15c, 15d are energized to produce fluxes of opposite directions between polepieces 12c, 12d and as their magnetic circuits are closed alternately by reciprocating member 14, rotation of rotor 17 is caused by the alternating field so produced. In Fig. 4, exciting coils 15e, 15f produce opposing. fluxes in the central core 12e carrying an output coil 24 in which alternating current is induced by the reciprocation of inductors 14a, 14b.
