Abstract: 712,737. Typewriters. NATIONAL CASH REGISTER CO. Dec. 2, 1952 [Dec. 18, 1951], No. 30502/52. Classes 100 (1) and 100 (4) Paper feed arrangements.-Rewind tally roll mechanism is provided for an accounting machine or cash register with a travelling carriage having a platen rotation of which feeds the record web in either direction. A travelling carriage 11 has end castings 12 between the front of which is secured an escapement bar 16 which engages rollers 18 and to the rear of which are secured an angle plate 20 and an angle bar 31, the former having a tube 21 which runs over rollers 22 for horizontal movement of the carriage. A platen roll 27 is rotatablv supported between the castings 12. Tally roll mechanism 11 is adjustably and detachably secured to the carriage 11 by hooks 42 engaging a roll 43 and by notches formed in downward extensions 37 of channel members 36 engaging slots cut in a square rod 44. A web of record material 61 is led from a supply roll 60 between a guide bar 63 and a lip 62 to go round the platen 27 under pressure tolls 50, 29, 64 before passing between a guide bar 66 and the upper portion of the bar 63 thence between guide extensions 67 of plates 34 again over the supply roll 60 to a receiving roll spindle 65. The spindle 65 has serrations at either end and is mounted in slots 84 at the end of two arms 85 beyond which knurled knobs 83 extend leaving undercut portions which are arranged to ride on curved surfaces 82 of the plates 34. The arms 85 together with arms 93 mounting driving rolls 90 are freely mounted on a shaft 86 a spring 89 attached to a pin 87 on the arms 85 holding the spindle 65 and rolls 90 in contact with the roll 60 whatever its size. It will be seen that the roll 60, rolls 90, and spindle 65 are on a common arc about the shaft 86 so that the operating relationship remains the same regardless of the relative sizes of the roll 60 and spindle 65. In use clockwise rotation of the platen 27 unwinds tape 61 from the roll 60 causing it to drive, through the rolls 90, the spindle 65 to wind the tape thereon while if it is desired to reverse the feed the platen 27 withdrawing tape from the spindle 65 causes it to rotate the roll 60, through the rolls 90, to rewind the tape thereon.

Title: Improvements in or relating to telephone systems
IPC: H04M1/74
Filed: 1929-10-09
Abstract: 341,044. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd., NEILSON, C. B. V., and TURTON, H. J.. Columbia House, Aldwych, London. Oct. 9, 1929, No. 30623. [Class 40 (iv)] A substation circuit in which the receiver is shortcircuited by the off-normal dial springs is adapted to be changed, by a simple operation such as the removal of a strap, into one in which the receiver is disconnected when the dial is off-normal. The first mentioned type of circuit which is advantageous for individual lines is unsuitable for party lines selectively rung over one or other of the lines since the local ground increases the current through the line relay. The induction coil is arranged between the switch-hook contacts and the transmitter so that one coil acts as a high frequency choke to obviate packing of the carbon granules in the transmitter due to sparking at the switch-hook contacts. The connections for use at a party-line substation are shown in full lines, wire E being grounded. The line is rung over L2. The lines L1, L2 are connected over cradle switch CS to induction coil 12, 13 and the receiver is connected across the circuit in series with normally closed dial springs 6, 7 so that when the dial is offnormal the receiver is disconnected, the transmitter being short-circuited by springs 3, 4. To use the circuit at an ordinary substation, wire E is connected by strap IS2 to L1 instead of to ground and springs 6, 7 are short-circuited by strap IS1. When the dial is off-normal, both the receiver and transmitter are short-circuited over springs 3, 4. The strap IS2 completes the normal ringing circuit. The circuit may be used for manual working by the addition of strap MS.

Title: Improvements in and relating to automatic fire alarms
IPC: G01K3/12
Filed: 1927-11-19
Abstract: 287,813. Vidal, A. E., (Compagnie Fran- þaise du Signum). Nov. 19, 1927. Alarms operated by expansion of solids.-In a fire-alarm of the kind operated by bi-metallic strips and adapted to give warning of both slow and rapid rises of temperature, a pair of bimetallic strips AB, CD are connected end to end with metals of similar expansion arranged on opposite sides of the compound strip AD so formed. The compound strip is fixed at one end A, the other end D being free, and the lengths or masses of the two strips AB and CD are so proportioned that the curvatures in opposite directions of the two strips balance one another during equal heating; i.e., the end D will be displaced along the line DA, but not laterally thereof. In case of rapid heating, the strip CD curves before the strip AB, which is heat insulated or of greater mass. The lateral displacement D, D<1> then declutches an electrical or mechanical alarm. For slow heating, when both curve at the same rate, the displacement D, D<111> declutches the alarm, or the movement of the point B may be arrested by an adjustable stop K. In a preferred arrangement, the compound strip is enclosed in a composite casing having a heat-insulating part around the strip AB and a conducting part, e.g. of thin copper, around the strip CD. In a modification, a pair of such compound strips AD may be arranged side by side with the metals reversely arranged, relative movements of the free ends D operating to declutch the alarm.
