IPC: G06K13/107
Filed: 1964-12-23
Abstract: 1,105,873. Feeding sheets. INTERNATIONAL COMPUTERS & TABULATORS Ltd. 7 Dec., 1965 [23 Dec., 1964], No. 52177/64. Heading B6B. Sheets in a stack 1 resting on edge on a base 2, and urged by gravity against a stop 9, engaging the top edge of the leading sheet, and the apertured front plate 4 of a suction box 5, are separated sequentially from the stack by first pulling the bottom edge of the leading sheet away from the stack, then pulling the sheet downwardly so that the top edge thereof is released from the stop 9, pulling the released top edge away from the stack, and then gripping the top edge by means which feeds the sheet upwardly from the stack. The top and bottom ends of the apertured plate 4 are bent away from the stack. The bottom edge of the front sheet is pulled away from the stack by suction applied from the box 5 to engage a rotating roller 10. When a signal is applied to an electromagnet 15, the end 21 of a bell-crank lever 19 presses the bottom edge of the sheet against the roller 10, whereby the sheet is pulled downwardly and released from the stop 9, and the top edge of the sheet is then pulled away from 'the stack by suction. The top edge of the front sheet also engages a rotating roller 22, and when a signal is applied to an electromagnet 30, an idler roller 26 on an arm 25 presses the sheet on the roller 22, and the sheet is fed upwardly from the stack, overcoming the suctional force exerted on the sheet. The sheet is forwarded by further feed rollers 32. In modifications, the rotating feed rollers 10, 22 may be apertured suction rollers which are rendered operative by controlling the source of vacuum connected thereto, and the sheets can be fed from the top of a stack which is raised by known means to maintain the top of the stack close to the plate 4.

Title: Improvements in and relating to automatic draining of liquids from compressed-gas systems
IPC: F16T1/20
Filed: 1965-12-14
Abstract: 1,114,607. Draining liquid from gas lines; centrifugal separator. HOERBIGER VENTILWERKE A.G. 14 Dec., 1965 [22 Dec., 1964], No. 52977/65. Headings BIT and B2P. [Also in Divisions F2 and F4] Liquid separated from compressed gas periodically drained from collecting sump 2 by a quick-acting drain valve 26, which is opened by a magnet 39 attracting armature 42 when a float 44 has lifted armature 42 sufficiently. As liquid accumulates, float 44 is lifted, its bush 45 sliding along coaxial piston 43, until the edge 46 of bush 45 engages armature 42, after which armature 42 and piston 43 slide on rod 37 into the magnetic field and armature 42 is drawn into engagement with abutment 47, which lifts rod 37 lifting sealing member 36 off the valve seat 27. As liquid is blown through valve 26 and outlet 33 by the gas pressure, float 44 falls, but armature 42 and piston 43 are retained by magnet 39, until the lower end of bush 45 engages valve seat 27 (as shown) and stops the liquid flow. Edge 46 of bush 45 and piston 43 provide a restricted gap by which gas escapes through open valve 26 so that the resulting pressure differential depresses piston 43, pulling armature 42 away from the magnet and closing valve 26 again. A handle 38 on the upper end of rod 37 permits manual operation of valve 26. Gas flowing from inlet 6 to outlet 7 passes through sintered filter 8 and cyclone chamber 23, with inclined vanes 22 and baffle 20. Valve seat 27 is vertically adjustable. Magnet 39 may be a permanent or electro-magnet, and is mounted in a non-magnetic plate 24. Sealing member 36 is ball-shaped, of soft material and secured by adhesive to member 34, attached to rod 37.

Abstract: 1397455 Vehicle bumpers IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 23 Oct 1973 [17 Nov 1972] 53185/72 Heading B7J [Also in Division F2] A motor vehicle has a bumper 7 connected at spaced points 12, 13 by energy-absorbing devices 8, 9 extending in straight lines to spaced attachment points 14, 15 on the vehicle, the spacing of points 12 and 13 being greater than that of points 14 and 15 so that the devices 8 and 9 diverge away from the vehicle, and the attachment at points 14 and 15 being rigid while that at points 12 and 13 is by resilient means formed by rubber blocks 26 so that the bumper end of each device 8, 9 moves towards the bumper end of the other device on movement of the bumper towards the vehicle. When an impact forces the bumper 7 towards the vehicle, energy is absorbed sequentially by deformation of the blocks 26, elastic deformation of a grooved plastics sleeve 25 disposed around a mandrel 23 of a ram 24 within a cylinder 20, and then extrusion of the sleeve 25 and plastics rings 31 and 32, 33 by stepped shoulders 27 and 28 of the ram acting on the plastics components 31, 32, 33 and 25. During such deformation, the connection points 12 and 13 approach the points 14 and 15 respectively, and thus the points 12 and 13 also approach one another. The blocks 26 may be prestressed by straps (42, 43), Figs. 5 and 6 (not shown), holding the bumper in a position displaced towards the vehicle. The sleeve 25 may be replaced by plastics Belleville washers (44), Fig. 7 (not shown). The energy-absorbing devices are disposed at an angle relative to the longitudinal vertical median plane 10 of the vehicle of between 3 and 30 degrees, preferably from 5 to 30 degrees and preferably 7 or 15 degrees.

Heading B1C. [Also in Division F4] A mixer and drier for granular material comprises a permeable table 12 for the upward passage of a hot air from a lower chamber C upon and along which table the material is mixed and conveyed from a loading hopper K to an unloading opening L by means of a truck G driven to and fro along guide rails 24, which truck has rotatable paddle-like members 40. A further chamber D beneath the unloading end of the table supplies cooling air to the material.

The luminance and chrominance signals played back from the magnetic medium are separated by filters 28, 33, the chrominance signal being fed to frequency converters 34, 35 which receive inputs from respective band-pass filters 39, 40 and provide signals at the standard PAL subcarrier frequency which are separated by band-pass filters 41 and 43, the signal separated at 41 having the red colour difference signal modulation axis leading the blue colour difference signal modulation axis by 90 degrees and being fed directly to a switch 42 operated at the end of each line period, and the signal separated at 43 having the red colour difference signal modulation axis lagging the blue colour difference signal modulation axis by 90 degrees and being fed to switch 42 via a one-line delay line 44, thus providing a PA6 chrominance signal at the output of switch 42. Band pass filters 39 and 40 receive the output of frequency converter 36 which receives a signal at the standard PAL subcarrier frequency from oscillator 37 and a signal at the frequency of the frequency-converted chrominance signal derived from the magnetic medium, from oscillator 38.
