IPC: B41J11/28
Filed: 1950-09-06
Abstract: 707,879. Typewriters &c. SMITH & SON, Ltd., W. H. Dec. 6, 1951 [Sept. 6, 1950], No. 22002/50. Class 100 (4) Paper feeds.-A continuous stationery feed apparatus for use in tabulators, typewriters or like machines having a driven rotatable platen 17, comprises two parallel shafts 11, 12 carrying pinwheels 13 to feed original and copy webs, the shaft 11 being driven from the tabulator &c. to feed the original web and the other shaft 12 being driven by an independent drive from the tabulator &c. to feed the copy web a limited amount after each printing operation. The two shafts 11, 12 are journalled in side plates 9, 10 adjustably secured to the machine frame 14 by ecentrics 16 and clips 15. The shaft 11 is driven by a gear 21 and an idler gear 20 loose on shaft 12 from a gear 18 on the platen shaft 19. The shaft extends through the plate 9 to a gear 52 which through a gear 53 rotates a gear 54. Adjustably screwed to the gear 54 is a disc 58 carrying two rollers 61 arranged to operate a switch 64. The operation of the switch 64 stops a continuous feed of the original web at the first entry position of a particular form-length of the web after it has been fed from the last entry of the preceding form and over the following form heading. The shaft 12, driving the copy web pin-wheels, is driven by pawl and ratchet mechanism, Fig. 4, in adjustable line steps at each imprinting cycle of the machine by a cam 44 engaging a follower 43. This engages a link 41 pivoted to a further link 40 oscillating a rocking arm 33 carrying two pawls 31 and (32 not seen). The pawl (32) engages with a line-spacing ratchet wheel 30 and the other pawl 31 engages with a ratchet 29 having a tooth or teeth to move the web a greater distance, e.g. equal to a copy form heading space. The ratchets 29, 30 are attached to a gear 27 free on the shaft 11 and which drives a gear 26 secured on shaft 12. When it is required to disconnect the drive of the copy web a solenoid 48 is energized and a connector 47 draws the link 41 free of the follower 43. The degree of line feed by the pawls 31, (32), is controlled by ratchet shields 38, 35, and a detent wheel 50 and a spring detent 51 accurately position shaft 12. In a modification, Fig. 5 (not shown), the arm 33 carrying the pawls 31, 32 is operated by the reciprocation of a Bowden cable actuated immediately after each printing operation. Specifications 408,125, 477,343 and 627,572 are referred to. Specifications 605,532, [Group XIX), and 648,729 also are referred to in the Provisional Specification.

D.C. power transmissions ALLMANNA SVENSKA ELEKTRISKA AB 19 April 1971 [19 Feb 1970] 22041/71 Heading H2F A high voltage converter station comprises a plurality of series-connected rectifier bridges 1<SP>1</SP> ... 5<SP>1</SP>, Fig. 4, one of the bridges 13, Fig. 2, having an extra control system 12 for reserve operation: the reserve control system 12 being arranged to provide a by-pass circuit by turning on the series-connected pairs of rectifiers (e.g. 1, 4) sequentially. This is achieved by operating group of rectifiers 1, 3, 5 as inverters and group 2, 4, 6 as rectifiers i.e. by firing one group with a delay angle greater than and the other group less than 90 degrees. During reserve operation, the commutation frequency may be less than the supply frequency. A reserve control system is provided for each phase. A pulse transformer or monostable 18 provides a pulse at the time of zero crossings of the voltage between phases R and S. These pulses are passed by an electronic relay 19 and the required frequency determined by pulse generator 20. Time delays t 1  and t 2  provide the delay angles greater than and less than 90 degrees. The bridge 13 may be isolated by means of by-pass switches operated in response to zero crossings and by isolators (not shown). Fig. 4 shows a station comprising two series chains of bridges 1<SP>1</SP> ... 51 and 6<SP>1</SP> ... 10<SP>1</SP>, bridges 1<SP>1</SP> and 6<SP>1</SP> being provided with extra control systems (not shown) for reserve operation.

Title: Improvements in or relating to automatic danger signals on railways
IPC: B61L1/04
Filed: 1928-07-30
Abstract: 314,251. Winkler, H. July 30, 1928. Electrical systems, automatic; track apparatus actuating signals other than on trains.-A vertical plunger is depressed by the leading train wheel and is pulled clear of the following wheels by an electromagnet or electromotor and held for a predetermined time interval governed by a time switch. The depression of the plunger, by means of a two-way switch, puts lamp or audible signals in and out of action. The first wheel of a train depresses the plunger 5 which actuates, by a ram 15 and a lever 8, a mercury switch 21 controlling through the time switch 29 an electromagnet 12 that pulls the plunger 5 clear of the train. The signals are operated by a similar ram 16 acting on the two-way switch consisting of two mercury contacts 23, 24 resting on triangular cams 27, 28 mounted on a shaft 20. To this shaft is keyed a ratchet wheel which is rotated through 60‹ on each upward movement of the ram 16 and closes the contacts 23, 24 alternately. To prevent overheating the electromagnet 12, the ram 15 switches in a series resistance by a second mercury contact 22. A system for protecting a rail crossing as shown in Fig. 9 comprises a contact on each side of the crossing, and time switches 29, 29' and signals 30 at the crossing. On depression of plunger 5 an electromagnet of the time switch 29 closes contacts 33 and completes the circuit of electromagnet 12. Simultaneously .current passes to a motor 40 of the time switch 29 which runs for a set time and then breaks the contacts 33, allowing the plunger 5 to return to its normal position after the passing of the train. The twoway switches are in series with one another and with the signals and as either plunger 5 is depressed the signals are put in or out of action and remain so until the next operation of either contact.

Title: Thermo-electromechanical multi-function support device
Inventor: SUOZZO LEONARD SALVATORE
IPC: F16L3/20
Filed: 1971-04-19
Abstract: 1,273,967. Pipe support. L. S. SUOZZE. 19 April, 1971 [17 Aug., 1970], No. 22543/71. Heading F2P. In a device for supporting equipment, such as a pipe 1, subject to thermal expansion, an actuating assembly, which is attached to the pipe at two locations, is connected to a coupling assembly having connector means for connection to a fixed support 56 and an electric motor 30 is operatively interposed  between the actuating assembly and the connector means. As shown, the actuating assembly comprises a rigid member 15 pivotably mounted on a plate 5 which is welded to the pipe 1 and a switch arm 27 which is connected to member 15 through links 14, 25 and is also connected to a plate 8 welded to the pipe and mounted on a main support plate 10. As the pipe undergoes axial expansion, the lever 14 rotates about pivots 22, 24 thus causing the arm 27 to traverse contacts C 1 -C 8  which are part of an electric circuit controlling the motor 30. Each contact C 1 -C 8  corresponds to a number of revolutions performed by the motor. Rotation of the motor shaft 32 is transmitted through gears 33, 34 to a screw 35 mounted for rotation in a thrust bearing 40. The screw 35, the thread of which is protected by bellows 48, engages a nut 41 on which are mounted plate members 42, 43. The nut 41 is prevented from rotating with the screw by pins 46, 47, attached to the plates 42,. which project through vertical slots in a bore wall 12 which is secured to the support plate 10. As the pipe 1 expands and the contact arm moves to one of the contacts C 1 -C 8 , the motor 30 is switched on and stops after a given number of revolutions, the direction of rotation being such as to lower the screw 35, and hence the plate 10 and pipe 1, through the nut 41 a distance which is a multiple of the axial expansion of the pipe whilst maintaining support of the pipe. Switches 44, 45 are contacted by pin 47 to switch off the motor at the limits of travel of the screw 35. The pipe thus controllably assumes a position in which the thermal expansion produces no strain on the pipe or its supports.
