Abstract: 860,260. Propelling rail vehicles. MITCHELL, F. G. Dec. 19, 1957 [Dec. 19, 1956], No. 38743/56. Addition to 795,673. Class 104 (2). A rail vehicle handling mule comprises a carriage movable on rails within a main rail track and mounting a pusher assembly movable between an inoperative lowered position and an operative raised position in which parts of the assembly are raised above the carriage and outside the width thereof to engage buffers or other laterally spaced parts of the body of the vehicle on the track, means for raising the parts situated substantially rearwardly of the pivoted connection of the parts with the carriage and means for maintaining the parts in operative position. A pair of pusher arms 14..pivoted on shafts 15 on a carriage running on rails within the main rails is connected by a pair of struts 18 to pivots on a crosshead 22 sliding on rods 23 on the carriage, the arms being raised by tensioning a traction cable 31 which is connected by drawarms 24, 25 to the crosshead. A dog engages behind the crosshead to maintain the arms in operative position. The dog is on the end of a bar 32 pivoted at 33 on the carriage, the end of the bar resting on the crosshead until the arms are fully raised. To lower the arms the dog is removed by a striker 36 striking a cam by the track, the striker being at the end of a transverse shaft 35 carrying a cranked bridle which when rotated raises the bar 32 to disengage the dog. The mule can be used for moving vehicles from one of a number of tracks on to a weighbridge on a traverser and then on to aligned tracks. The vehicles are propelled on to the traverser by an auxiliary elongated mule which runs on a track beside the main track and aligning with a mule track on the traverser. The mule propels a vehicle on to the traverser by a pivoted roller arm which engages the vehicle wheel and pivots out of engagement when the mule moves in the opposite direction. The traverser has a control house having an electric motor driving two hydraulic pumps operating motors which drive the traverser and cables for the mules, the traverser being driven by a rack-and-pinion and the cables by winches.

Abstract: 964,847. Shaping concrete. SKOVDE GASBETONG A.B. Oct. 15, 1962 [Oct. 24, 1961], No. 38873/62. Heading B5E. A method of planing the side surfaces of parallelepipedic-shaped blocks of concrete 1 comprises moving a rotary cutter 12<SP>1</SP> in contact with the block along the plane of the desired finished side surface so that its cutting teeth enter the side surface at one edge thereof and leave the side surface in a portion thereof which forms an angle with the plane of the desired finished side surface. In order to avoid a ragged edge caused by the teeth 11 of the cutter 12<SP>1</SP> when they leave the block, a second cutter 3<SP>1</SP> is arranged to cut an angular surface 7 on the side surface ahead of the cutter 12<SP>1</SP> as shown in Fig. 1, the cutter 3<SP>1</SP> rotating in an opposite direction to the cutter 12<SP>1</SP>. The teeth of the cutter 12<SP>1</SP> leave the side surface just above the bottom edge so that a slight tapered portion 15 is left; a second pair of cutters 3<SP>11</SP>, 12<SP>11</SP> may be used to simultaneously plane the opposite side surface. In a modification, the angular surface may be of a large angle, e.g. 45 degrees, and produced by a conical cutter. In a further modification shown in Fig. 5, a corner of a block 1 is removed by a cylindrical cutter 27, two cutters 12a being moved along the block so that their teeth break out of the side surfaces 25 to leave a slight chamfer 26. Instead of the cylindrical cutters 12, a facing cutter having removable tipped cutting teeth may be used.

Title: Improvements relating to electronic counters
Inventor: WALKER GEORGE SANDERSON
IPC: G06F11/10
Filed: 1960-11-15
Abstract: 960,375. Counters. FERRANTI Ltd. Feb. 12, 1962 [Nov. 15, 1960], No. 39121/60. Heading G4A. Operation of an electronic counter is checked by applying the input simultaneously to a residue computer operating to a different modulus, the several digits in the counter being operated on according to known arithmetical rules so as to give a result which is the same as the output of the residue computer as long as the counter is functioning correctly. A reversible decimal counter 11 of the type described in Specification 914,964 receives impulses from a source 12, the direction of count being controlled by a device 13. The input is simultaneously fed to a three-stage ring counter 15 which marks one of leads 15<SP>1</SP> representing the remainder modulus 3. The digits in each decimal denomination likewise mark remainder modulus 3 leads 23, all the remainders being added by networks M 0 , M 1  &c. to give a remainder output on leads 17<SP>1</SP>. Disparity between the markings on leads 15<SP>1</SP>, 17<SP>1</SP> is revealed by comparator 24 to give an alarm. The alarm is subject to a slight delay to prevent false indication. The apparatus may be used to measure movements of a machine tool with two photo-cells responding to fringe pattern and direction of movement to produce add or subtract signals (Fig. 3, not shown). To guard against an error signal being caused by the output of one photo-cell lagging behind the other the alarm is given only when the error reaches 2. Counters with mixed bases may be used (Figs. 4 and 5, not shown). Quinary base, Fig. 6. A quinary base counter checked by a ternary base residue counter requires that the remainders in the odd-numbered denominations must be subtracted from the remainders in the even-numbered denominations. The remainder leads 1, 2 from one network M to the next are therefore reversed. A scale of 11 counter can be checked modulo 5. Counting below zero, Fig. 7, negative numbers are represented by their 9's complement in a decimal counter, a circuit 51 adding or subtracting 2 to the check circuit as the counter passes through zero in anegative or positive direction, respectively.

Title: Clutch
IPC: F16D43/12
Filed: 1961-11-03
Abstract: 1,003,283. Friction clutches. B. HIRANO. Nov. 3, 1961 [Dec. 3, 1960], No. 39393/61. Heading F2L. The pressure engaging a centrifugally or manually-controlled friction clutch in a motor cycle &c. is reduced as the transmitted torque increases, by shear forces acting on one or more non-metallic coupling members in the drive path. As shown, a driving shaft 1 is fast with a drum in which are splined discs 4 interleaved with driven clutch discs carried in a drum 6 rotatable about the driving shaft. Axially-directed non-metallic coupling members in the form of rubber rods 11 transmit torque to a driven gear 10. The clutch is engaged by pressure transmitted through a rod 12. Increasing torque causes the rubber rods 11 to turn relatively to the clutch axis, due to the shear forces developed, and thus reduces the clutch-engaging pressure.

Filed: 1972-08-31
Abstract: 1497789 Relaying arrangements SIEMENS AG 31 Aug 1972 [25 Feb 1972] 40514/72 Heading H4L In operation of a radio-telecommunications system (Fig. 2) in which any one of a number of subscribers associated with a first station can be connected to a selected subscriber associated with a second station not directly accessible from the first, the connection is established via a relay station by making a transmission which is radiated to all adjacent accessible stations and receiving such transmission at the receiving stations via respective directional antenna. Thus, when a subscriber A associated with station I dials a subscriber B associated with station VI, a call signal is transmitted on a service channel from station I. The signal is received at station III and, after adding to the signal a code which identifies station I as the original, station III transmits the signal non-directionally. Stations II, IV and V receive and retransmit the signal (with further coding to establish station III as the caller) and station VI receives the signal simultaneously from stations IV and V. One of these signals is rejected and, using the coding of the other, a return transmission from station VI on its service channel is received by the directional antennµ of the relevant relay stations and relayed back to the original station I. Thus, in establishing the return link, individual stations withdraw only information intended for them. The subscribers are connected to their associated stations by radio or by line and vocoders preferably are included to reduce bandwidth. Speech channel information, which is transmitted in digital form, can be pulse code modulated or pulse delta modulated. The service and other priority channels are always open. In the transmitter stage of the station (Fig. 4) a random generator ZG, whose output is similar to a normal speech noise spectrum, is connected to any channel modulator KM not in use at a given time to hinder analysis of the transmission by unauthorized parties. Each station has a number of different directional antennµ, one for each adjacent accessible station, and each antenna EA1-EA4 is associated with a respective receiver RFE1-RFE4. The stations can be mobile (Fig. 1, not shown). Resistance of the system to jamming can be increased by reducing the mesh size (i.e. using an increased number of stations. In special cases, some stations can be interconnected by line, conventional narrow band relay equipment or scatter equipment.
