Title: Improvements in loaders for sugar cane or the like
IPC: A01D51/00
Filed: 1955-11-10
Abstract: 785,402. Grab forks. MACSPORRAN, A. Nov. 10, 1955 [Nov. 16, 1954], No. 32196/55. Class 78 (4). As a grab fork 36, Fig. 1, is lowered to retain material on a fork 19 it tensions a flexible member 58 extending from the grab fork to constrain the material. The device for carrying sugar cane illustrated is carried by arms 10 at the front of a tractor and includes conventional tripping means for permitting the fork 19 to tilt about pivots 17 to discharge the load. The grab fork 36 is turned about its pivot 30 against the bias of a leaf spring 43 by an hydraulic ram 45. The anchorage 48 for the ram 45 is carried by a bell crank lever 50 pivoted at 54 to the bracket 26 and normally held against a stop 55 by coil springs on the shaft 54. As the ram 45 lowers the grab fork 36 its line of action passes to the lower side of the shaft 54 so that the bell crank 50 is turned to tension a rope 58 looped over a bolt 52 on the bell crank 50 and carried around sheave pins 42 on the grab fork 36 to anchorages 41 spaced on opposite sides of the grab fork. The bolt 52 may be placed in any of several holes 53 in the bell crank 50. The grab fork 36 includes inner arms 38, Fig. 2, converging towards their rear ends where they are welded to a pair of spaced cranked arms 39, Fig. 1. At their forward ends the arms 38 are connected by cross members and spacers 41 to outer arms connected by cross members 40 and secured to the shaft 30. The tips 37 of the arms may be curved in section so that they may be welded at the edges to form a pair of hollow tips 37. Bolts 21 on the fork 19 permit their angle to the arms 10 to be adjusted.

IPC: G06F3/023
Filed: 1967-07-14
Abstract: 1,189,357. 'Data stores. KOMBINAT ZENTRONIK VEB. 14 July, 1967, No. 32452/67. Heading G4C. Digits are written in turn into a magnetic core store in complement form, only the coordinate lines corresponding to the complement values being energized, and read out in true form directly by energizing all the co-ordinate lines, the same driver stages being used for both writing and reading. Successive manually-entered digits of a number are stored in complement form in respective positions of a core store selected by a ring counter stepped up in synchronism. When the number has been completely stored, a marker is stored after it and the counter jumps to its maximum value. The counter is then stepped down, setting any unset cores in each store position in turn until the marker is detected when, provided a computer is ready, it continues to step down, setting any unset cores thus supplying the stored digits to the computer in true form. When the computer has received the required number of digits it clears the core store and resets the system. If the number of digits in the core store was less than the number required, the system will attempt to set unset cores in the first store position more than once (since the counter does not go below its lowest position) thus sending zeros to the computer on attempts after the first since any unset cores would have been set on the first attempt. Thus high-order non-significant zeros need not be entered manually.

Title: Improvements in driving tools for fasteners
IPC: B25B23/06
Filed: 1969-06-30
Abstract: 1,268,716. Screwdrivers. ATLAS COPCO A.B. 30 June, 1969 [8 July, 1968], No. 32818/69. Heading B3N. [Also in Division B8] A driving tool for applying fasteners, e.g. screws or nails, to a workpiece comprises guide jaws 30, for holding a fastener, having surfaces for co-operation with a fastener to cause the jaws to release the fastener as it strikes the workpiece. A power-operated screwdriver comprises a body 20 having elongate slots 22 in which are mounted guide jaws 30. Normally these occupy a closed position (Fig. 5), in which they are urged by spring-biased wedge members 32 into contact with a rotatable driver 15. Rear surfaces 33 of the guide jaws abut against complementary surfaces 23 formed at the ends of the slots 22 in the guide body 20. The guide body is slidable within an outer sleeve 12 and is normally biased to an extended position relative thereto to retain a clutch 11, 14 for rotating the driver from a fluid pressure motor, in disengagement. The guide jaws have recessed forward ends providing surfaces 30<SP>1</SP> which cooperate with the head of a fastener when held therein to cause the jaws to be moved to an open position (Fig. 6) when the fastener strikes the workpiece, by release of the jaws from the wedge members 32. The driver is advanced towards the workpiece by pressing the tool against the latter to cause retraction of the guide body 20 within the sleeve 12, whereby, as the fastener is released the clutch 11, 14 engages to rotate the driver. The clutch is disengaged, by a known mechanism, when rotational resistance, due to the fastener head penetrating into the workpiece, increases. Alternatively, by adjustment of a setting nut 27, it can be arranged that the guide body 20 is fully retracted just prior to full screwing down of the fastener. Fasteners are fed into the tool through a feed opening (24) (Fig. 3, not shown), in the guide body 20. The fasteners, supplied, for example, in a plastics band (38), are fed by a manually operable mechanism. Rotation of a lever (48) in one direction causes an ejector (44) to force a fastener, aligned with the feed opening (24), from the band (38) into alignment with the driver in its retracted position, where the fastener is held by the guide jaws. Simultaneously, a feeder (45) is retracted to a position behind a succeeding fastener whereby rotation of the lever (48) in the other direction causes the ejector to retract and the feeder to advance the band to position the succeeding fastener in alignment with the feed opening. A stop arm (47) engages behind another fastener to prevent rearward movement of the band during retraction of the feeder.

Abstract: 1500222 Facsimile system; secret transmission COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 6 Aug 1975 [9 Aug 1974] 32835/75 Headings H4F and H4R A facsimile transmission system includes a buffering arrangement incorporating magnetic tape image stores in both transmitter and receiver, whereby upon reproduction of the image, disturbances due to instantaneous tape jitter and longer term drifting are avoided. Binary image data of an entire image are multiplexed at a first rate H 1  on to a multitrack continuous loop magnetic tape (described w.r.t. Figs. 1, 2 and 3 (not shown)) along with a pilot clock signal. The recorded signal is demultiplexed and transmitted at a second rate H 4  commensurate with the transmission line capacity. At the receiver the entire image signal is multiplexed on to a similar tape unit 10, Fig. 4, at rate H 4 . The signal is then read from tape 10 via demultiplexer 30, line sequentially and loaded into one of three single line stores 31, 32, 33, at a third rate H<SP>1</SP> 7 . The data in these stores are processed sequentially in one of three modes: (a) loading at rate H<SP>1</SP> 7 ; (b) recirculating to bring about a desired phase change; (c) unloading at a fourth rate H 7  determined by reproduction apparatus 7. The processing at any instant is controlled such that each mode is in operation at all times but switched between the three stores at the line frequency under the control of unit 36. In an alternative embodiment entire image data is loaded on to tape 10, Fig. 5, at first rate H 1 . Then consecutive recorded "lines" are loaded alternately into single line stores 71, 72 at second rate H<SP>1</SP> 1 . Simultaneously with the loading of one store the contents of the other is transmitted at rate H 4 . Tape drive is interrupted when the line store is fully loaded until the other store is fully empty. At the receiver, Fig. 6, incoming "lines" are loaded alternately into line stores 81, 82 at rate H 4 . During the loading period of one store the other is unloaded at rate H 7  on to a similar tape unit 10 the drive of which is again interrupted when the latter empties until the former fills. When the entire image data are loaded on tape 10 a reproduction unit 7 unloads it at rate H 7  for subsequent processing in unit 88 which performs the phasing adjustment as described in Fig. 4 prior to facsimile production at 7.

Abstract: 1,191,318. Positive electrodes having principal and secondary active materials. ESB Inc. 19 July, 1967 [20 July, 1966 (2)], No. 33150/67. Heading H1B. A positive electrode comprises a principal active material and a secondary active material in the form of a layer which masks the principal active material from the electrolyte and which is stable in the electrolyte and in its undischarged state is electrolyte-impermeable but on discharge becomes permeable, permitting access of the electrolyte to the principal active material. Preferably the secondary active material is in electronic contact with the principal active material, has a lower potential than the principal active material, and has a discharge product that is oxidizable thereby, so that on discharge electrolyte is admitted to the principal active material which then reoxidizes the secondary active material and is itself reduced, the electrode thus developing the potential associated with the secondary electrode throughout discharge. Suitable combinations of principal and secondary active material are AgO-Ag 2 O; AgO-HgO; AgOMuO 2 ; KMnO 4 -Ag 2 O; and KMnO 4 -HgO; other suitable principal active materials are CuO and S. In Fig. 2, which differs from Fig. 1, only in the presence of the optional layer 20, the lid (2) is tin-plated steel containing the negative electrode (8) of finely-divided amalgamated zinc; this is separated by an electrolyte absorbent layer (9) of, e.g. matted cotton fibres, and a membrane barrier (10) of, e.g. " Cellophane " (Registered Trade Mark) or polyethylene or PVC containing a polyelectrolyte from the masking layer (12) of Ag2O, dispersed in a continuous phase in styrene, under which lies the main body (11) of the principal active material AgO, housed in the nickelplated steel cup (31); the optional layer (20) between the main body (11) and the cup (3) is of the secondary active material Ag 2 O, and functions as described in Specification 1,154,837, being re-oxidized, on discharge, by the principal active material and maintaining the electrode potential at the Ag 2 O-Zn value throughout discharge.
