Abstract: 643,924. Typewriters &c. LAMSON PARAGON SUPPLY CO., Ltd., and GARWOOD, V. W. May 3, 1948, No. 12093. [Class 100 (iv)] An attachment for writing, tabulating or recording machines for removing the perforated feeding margins from webs as they issue from the machine comprises a detachable frame carrying transverse spindles 14, 39 upon which an endless moving tractor 12 having sprocket pins for engaging marginal holes in webs, is adjustably mounted, and a pair of transverse spindles 24, 25 carrying cutting wheels 22, 23 arranged one above the other with their cutting edges overlapping, the wheels being driven in opposite directions and at peripheral speeds greater than the linear speed of the web in order to keep the web taut as it is cut or trimmed. The side plates of the attachment are slotted at 48, 51 for detachable mounting on the machine and carry adjusting screws 55 which bear on a machine frame transverse rod which enters the slot 51 so that the attachment may pivot about a further rod in the slot 48. This pivoting ensures correct meshing of pinions on the spindles 14, 24, 25 with gears in a gear-box fixed on the outer side of one of the side plates. The tractor 12 is transversely adjustable along keyways on the spindles 14, 39 and may be fixed by a screw 19 against a further spindle 15. Pivotally attached to the tractor is an arm 37, the free end of which engages in one of a number of grooves 41, 44 on an extension 42 of the lower cutting wheel 23. Each cutting wheel is carried by a sleeve keyed to its respective spindle so that by means of a coupling plate 26 and the arm 37, the cutting wheels and the tractor are aligned. Relative adjustment between the marginal feeding holes in the web and the line of cutting is made by setting the arm 37 in one of the grooves 41, 44. The wheel 22 is so mounted that it can be withdrawn from contact with wheel 23 and held out of action so that the web can pass without being trimmed. For this purpose the wheel 22 is mounted on a sleeve 28a which rotates within a second sleeve 29 so that when a control lever 33 is rotated a pin 32 riding up an inclined surface 31 draws the wheel 22 from wheel 23 against a returning spring 29a. The wheel 22 may be held away by anchoring the lever 33 behind a pin 34 on the plate 26.

Title: Improvements in or relating to electrical signalling systems
IPC: H04L12/18
Filed: 1936-05-04
Abstract: 469,348. Electric signalling systems. ERICSSON TELEPHONES, Ltd., and LIMB, F. May 4, 1936, Nos. 12519 and 12520. Drawings to Specification. [Class 40 (i)] In a system in which, in response to a demand, signals indicating the price of a selected securitv are transmitted to a subscriber, an additional signal is given if the price is unstable. The invention is described as applied to a system similar to that described in Specification 441,642, in which impulses of varying polarity are distributed by relay chains and pass to the central station through a sub-station common to a number of subscribers. To obtain a quotation a subscriber operates a keyset to send positive and negative impulses through the sub-centre to the main station at which relay chains distribute the impulses to selecting relays which lock up. The receiving arrangement comprises two parallel connected relays in series with rectifiers. When the selecting code has been received switches, individual to the selected stock and of the type described in Specification 441,642, are connected to the line circuit so that positive and negative pulses pass over the signalling circuit to operate relays in storage groups at the subscriber's premises which control the illumination of lamps in a display panel. If the price of a stock is fluctuating, apparatus at the main station causes a final negative pulse to be sent, and a lamp at the subscriber's premises flashes to indicate an unstable price. An all-blank display is given if the price indicators are being altered when a demand is received or whilst a price is being signalled, the key controlling the all-blank transmission being preferably interlocked with the indicators. Special codes are reserved for testing purposes, all the indicating lamps being lit in turn if all the testing codes are successively set up. As described in Specification 441,642 the display remains on the panel until released by operation of a cancel key although the common equipment is freed for use by other subscribers and a user cannot obtain a second quotation if a further subscriber is waiting to use the common equipment. Further prices of a particular stock may be obtained by operation of a repeat key which releases the display and initiates retransmission of the stock code. As described two pairs of wires are provided for signal and checking pulses respectively, but a single pair of wires only is necessary if impulses of varying polarity and of varying frequency are used for the two types of signal. The checking pulses are transmitted after each pulse to allow the next pulse to be sent, and the loop is shorted or bridged by a resistance between pulses to discharge the line of stray currents. Faults on the line cause blank displays to be given at the subscriber's premises, the unstable indicating lamp to flash and alarms to be given at the central office. Suitable circuits are described in the Specification.
