IPC: B61H15/00
Filed: 1956-09-07
Abstract: 804,822. Brake transmission gears. SVENSKA AKTIEBOLAGET BROMSREGULATOR. Sept. 7, 1956, No. 27482/56. Class 103 (1). In an automatic brake slack adjuster of the kind described in Specification 421,759, in the release position of the brake a projection 45 on the mechanism casing 19 is in contact with the side 44a of a respective recess 44 whereby in all possible angular positions of the ring 43 and its thread 24 in relation to the thread 23 on the extension sleeve 9, the axial distance between the projections 45 and the portions of the bottom of the respective recesses 44 facing the projections 45 is greater than the axial distance between the coacting faces 9a and 12a of the extension sleeve 9 and the retaining ring 12 respectively with the slack adjuster in the condition, should a shock or the like create a pulling force in the brake rod formed by the slack adjuster, nothing will occur other than that the spring 49 may yield to the force and thus permit the projections 45 to move further into the recesses 44 without reaching the bottom thereof so that the faces 12a and 9a of the retaining ring 12 and the extension sleeve 9 respectively, will abut one another to prevent unintentional rotation of the rotatable parts 11, 12, 13 and 14 of the slack adjuster under the action of the shock. The construction contrasts with the prior art wherein the means for locking against unintentional increases of slack due to shocks are associated with the actuating means and thus rendered more complicated.

Abstract: 1,056,274. Producing sheets. AUXILIARY ROLLING MACHINES Ltd. Oct. 18, 1963 [July 19, 1962], No. 27739/62. Headings B3A, B3L and B3M.  A method of reducing the thickness of a sheet comprises feeding the sheet through rolls and also passing the sheet past a shear blade which cuts off a surface layer, the sheet being supported on the side opposite to the blade. The rolls 22 draw the strip 34 between blades 38, 39 which take off layers 36, 37. The upper blade can be swung upwardly by a handle 43 to insert a strip initially and the lower blade can be raised or lowered by a wedge 48 adjusted by graduated end-screws. The strip is guided by T-blocks 53 also adjusted by screws. To produce brass strip, an ingot is hot-rolled, coldrolled, annealed at 500‹ C. for two hours and then passed through the machine. The rolls 22 further reduce the thickness of, and workharden, the strip. Further rolling passes may then be made. During cutting, the blades may be reciprocated along their lengths and in opposite directions by cams or cranks. The blades may be set at angles to each other across the strip and the strip backed up by plates, they may be curved or they may be composed of two blade-sections in forward-, or rearward-, facing V-formation.

[Class 146 (ii).] A device for teaching arithmetic comprises a front member t provided with hundred holes equally spaced in a square to form ten horizontal lines and ten columns, and a back member having marked upon it the numbers of the multiplication table of Pythagoras, a number being situated behind each hole, together with means capable of obstructing all except one desired number from being visible through the holes. The obstructing means comprises a series of vertical bands which are arranged behind the columns and are formed in two differently coloured parts, one similar to and the other contrasting with the colour of member t, the two parts being united to form a long band by means of a window. The bands pass over top and bottom rollers and any of the bands may be caused to move when the handle e is operated by raising the appropriate lever h, when the band is gripped between the roller carried by the handle e and a roller mounted on the lever h. By adjusting the bands, certain holes may be shown in contrasting colour, while any desired number may be revealed through the appropriate window. For use with the device, there is also provided a member i, Fig. 4, preferably formed in two parts which may be united, each part carrying five hinged rods m on which are fixed balls l, adapted to fit in the holes in the board t, when the rods m are erected. By raising three of these rods and inserting them eight times into twenty-four holes, the operation of dividing twenty-four by three may, for example, be demonstrated. Along the sides of the board t, the numbers 1 to 10 may be marked and an abacus p may be provided.

Each link comprises five wires a ... e. Magnet SMO controls the connection to dead terminals. Normal call. A line relay LR operates in the usual manner and applies potential to wires m<SP>3</SP>, m<SP>4</SP> to identify the calling line in a marker and to start a selecting operation. The marker selects a link, operates a selecting magnet, say SM9, and applies a momentary potential to wire m<SP>5</SP> when the operation of SM9 is signalled back over ml. Magnet BM operates and is held by a potential on the line c. The marker is released and the call is completed with the help of the register. Faulty line. If no selecting digits are received by the register, a time control causes the register to cut off the holding potential for BM in wire c and to seize the marker which operates the selecting magnet SM0. The switch operates as before. Relay LR releases when BM operates and BM is held over contact 2, line La, Lb, contact 1 and, if desired, over a buzzer signal transformer Sui. When the line loop is broken, the equipment returns to normal. Any outgoing call meeting a busy condition may be transferred to the dead terminal position controlled by the magnet SM0. A metering device is shown at SM.

Title: Improvements in and relating to telephone coin collectors

IPC: H04M17/02
Filed: 1964-07-09
Abstract: 1,119,572. Coin-freed telephones. ASSOCIATED AUTOMATION Ltd. 8 July, 1965 [9 July, 1964], No. 28348/64. Heading G4V. [Also in Division H4] The insertion of a first coin into a telephone call box rotates disc 2A, so that pawl 2D rotates lever 3, and hence by pin 4B, also lever 4, clockwise to the position shown. This raises link 5, and straightens arms 6, 6A so as to close shutters 7B, 8B beneath coin tubes (not shown) in which inserted coins of various denominations are temporarily held. The first coin depresses arm 11, which is then held by latch 12 in the position operating a balance arm contact, so as to open circuit a diode which otherwise short circuits speech signals on line reversal when a party answers on a local call. Thus coin insertion can take place to permit speech to the called party either before or after that party answers. Line reversal also operates a solenoid C, so that its armature 10C releases a hammer 10B to engage a pin 9B on a member 9 located between the upper parts of the shutters 7B, 8B. This tilts the member 9 clockwise, releasing shutter 8B, which is pivoted by linkage 6A, 5, 3, 4 and spring 4C, to release held coins into a cash-in shoot. On premature hanging-up, the hand set deflects lever 14, to rotate member 9 anti-clockwise and thus release shutter 7B to release held coins into a refund shoot. On hanging up after cashing-in, member 9 is prevented from tilting anti-clockwise by the displaced shutter 8B, lost motion between lever 14 and the member being permitted by jaws 15A, 16A sprung at 17. In any event, insertion of the first coin for the next call raises link 5 again to restore either shutter to the position shown. The member 9 is thus released and is levelled by abutments 6<SP>1</SP>, 6A<SP>1</SP> on arms 6, 6A so as to lock both shutters closed. An anchor 18 pivoted at 18A is arranged to be displaced slightly by opening of either shutter so as to tap the other shutter and displace any coins resting on the other shutter into the opened shoot. Hanging up also releases latch 12 and arm 11. The coins, after testing, also send value signals to exchange for operatorconnected calls. Premature hanging-up to obtain refund, and displacement of shutter 8B to effect cashing-in, which can be effected by a caller's push-button, also send distinctive signals to the operator.
