Abstract: 1,118,677. Endless track locomotives. BERTIN & CIE. 14 Jan., 1966 [15 Jan., 1965], No. 1872/66. Heading B7H. [Also in Divisions B3, B8, E1, F2 and H2] In an endless track vehicle 1 running on T- section rails 5, adhesion of the tracks 3, carried on pairs of driving wheels (2) having pneumatic tyres (Fig. 3, not shown), is promoted by air cushions acting on the inner faces of the tracks 3 to press them against the rails 5. The air cushions are formed in carriages 7 articulated to the vehicle 1 and supplied with compressed air at 8. Cushions 12 acting on the undersides of the rails 5 and maintained by the carriages 7 react the force produced by the upper cushions. Alternatively the reaction is provided by wheels (11) on the carriages (Figs. 1, 2, not shown). In Fig. 5 (not shown) the driving wheels (2) are raised clear of the rails 5, adhesion of the endless tracks on the rails being due solely to the air cushions.

Title: Improvements in pulse producing system with interrelated repetition frequencies
IPC: G06F1/04
Filed: 1953-01-23
Abstract: 764,521. Pulse generating circuits. COMPAGNIE DES MACHINES BULL. Jan. 23, 1953 [Jan. 24, 1952], No. 2050/53. Class 40(6) Pair of pulses B1, B1 from generator 15 Figs. 1, 2, 5 and 6 of multiple periodicity are produced from master pulse pairs A4, A4 by applying the master pulses to a coincidence gate 1b, Fig. 5 and a mixing or buffer circuit 1c feeding over diodes 98a, 99a a regenerative amplifier 1a. The second inputs of the circuits 1b, 1c are fed from the output transformer winding 102b over a delay line 20a to produce pulse train C1. At time toa , the outputs from circuits 1b and 1c are -V1 and O respectively so that discharge tube 103 remains biased off by battery 143. As A4 becomes more positive so the output from circuit 1b tends to earth and the grid potential of tube 103 rises and anode current-passes, the tube remaining conducting due to feedback over winding 102d. At time t4 both inputs to circuit 1c fall to -V1 being limited in their amplitude by diodes 120 and battery -V1. The grid of tube 103 is thus taken to this potential due to diode 99a conducting so that the tube ceases to pass current to terminate pulses B1, B1. Pulses B2, B2 are produced in a similar manner in generator 2 to that used in generator 1, connections being added to supply delayed B1 and B1 pulses to the circuits 2c, 2b, This process may be continued, a generator 3 producing pulses D1, D1 and generator 4 pulses D2, D2: The output from the gate associated with generator 4 also feeds over resistor 149 a pulse amplifer 5; Fig. 8 giving pulses F0, F0. These pulses are fed to a generator 7 with a feedback connection as used with'generator 1 to produce output pulses E0, E0. The feedback pulses are also applied, together with the F0 pulses to a gate 6b connected to a pulse amplifier 6a to produce pulses G0, G0. Phase-shifted pulses D3, D4 and D5 are produced by the use of generators 8, 9 and 10 Fig. 9 (not shown) similar to generator 1 but with the addition of connections between each and the succeeding generator over a delay line. The pulse G0, G0 are used to control generators 11...14 similarly interconnected to produce four phaseshifted pulses E1, E2, E3 and E4. The master pulse source may be of the type described in Specification 714,746 and the pulses generated used in calculators as described in Specification 740,756 and the 742,869 [both Group XIX].

Title: Method and apparatus for feeding articles to a packaging machine
IPC: B65B35/24
Filed: 1966-01-17
Abstract: 1,103,310. Endless conveyers. HÍFLIGER & KARG O.H.G. 17 Jan., 1966 [15 Jan., 1965], No. 2129/66. Heading B8A. Apparatus for feeding articles to a packaging machine includes an endless control conveyer which ensures that the speed and spacing of the articles are in accordance with the speed and spacing of conveying receptacles of the packaging machine. As shown, articles 14 on a belt 6 are fed to a cartoning machine 1 comprising receptacles 2 driven by a chain 3. A control conveyer includes driving members 4, each having a wing portion 4<SP>2</SP> engageable with a respective article 14 and a pin 4<SP>1</SP> engageable with a guide rail comprising sections 15, 16, the members 4 being spaced from each other the same distance S as the receptacles 2. The speed Vu of chain 5 of the control conveyer is the same as the speed Vk of the receptacles, but the speed VB of the belt 6 normally differs from the speeds Vu, Vk. The section 15 of the guide rail is movable by a magnet 12 under the control of a photo-electric device 8-10. Assuming the speed Vu of the control conveyer to be greater than that of the belt 6 and a contact 13 to be closed by a driving member 4, a pin 4<SP>1</SP> will be in engagement with the guide section 15 before an article 14 has reached this section. This is then retracted by the magnet 12 (Fig. 2) and the pin 4<SP>1</SP> drops into the space between two articles 14, 14<SP>1</SP>. The pin 4<SP>1</SP> catches up with the article 14<SP>1</SP> and the latter is moved forward at the speed Vu equal to that of the cartoning receptacles 2. If the speed Vu is less than that of the belt 6 the articles are slowed down by the pins 4. In a further embodiment (Figs. 3-6, not shown), a storage drum (17) is used in the control of the driving pins (4). The guide rail (18) for the pins is in eight sections which are actuated by magnets (22). When the light control (8, 9) is interrupted by the passage of an article, pins (19) of the drum (17) which are opposite a magnet (24) will be shifted. These pins cause the associated magnet (22) to release a driving pin (4) which speeds or slows the article, as before. In place of the drum (17) with its pins (19) use may be made of some other known form of mechanical, magnetic, electric or pneumatic information-storage element.

A lathe has work-holding means at one end of the spindle and manuallyoperable means for adjusting the work-holding means in angular relation to the spindle. The lathe bed 20, Fig. 4, is mounted on a bench or cabinet which contains an electric driving motor, belt-driving gear and a gear-box, the final drive being through a belt 31 to a pulley 41 on the hollow lathe spindle 32. The latter is coned at its outer end 53 and is engaged by the coned end of a draw tube 51, which is moved in a conventional manner by cam levers 106 and a ring 99 with hand-operated lever 98, Fig. 3. The outer end of the draw tube is split and closes on a split intermediate sleeve 54, Fig. 4, which in turn closes over a split ball-ended work-holder 92. A rod 114 extending rearwardly through the spindle is integral with the work-holder 92 and carries a rectangular plate 113, Figs. 4 and 13, at its rearward end. The top and bottom edges of this plate are engaged by wedge fingers 111, 112, extending from a sleeve member 61, and at right angles, another pair of wedge fingers 118, 118a extending from a bar 115 engage the side edges of the plate 113. The bar 115 and sleeve 61 are coaxial and are rotatably secured at their rear ends to plates 119, 63, respectively, Fig. 3. These plates extend upwardly and are secured to the ends of parallel bars 120, 64, respectively. Each bar is arranged in bearings 79, 82, Fig. 4, in a casing mounted on top of the lathe headstock, and an adjusting screw 78 with knurled nut 77 permits finger-adjustment of a rod in an axial direction. A spring 89 is arranged to take up backlash in the adjusting means. The work may thus be gripped in the chuck and angled by the adj usting means until a face of the work is at right angles to the centre line, and other faces may then be turned parallel to the original face.
