Title: Machine for running together a pair of gears
IPC: G01M13/02
Filed: 1973-08-17
Abstract: 1402383 Toothed gearing; machining safety devices GLEASON WORKS SA 17 Aug 1973 [13 Sept 1972] 39006/73 Headings F2Q and F2J In order to operate a machine for the running together of a pair of meshing crown wheel 10 and pinion 18 gears for the noise testing thereof i.e. to establish an optimum meshing engagement, known as "pinion cone searching", which may vary slightly from the true theoretical meshing position, and is detected by a relatively low noise level when the gears have reached a smooth running engagement, the machine operator must use both hands simultaneously to operate a fine adjustment handle 42, having a switch 76, and switches 90 to complete a circuit (Fig. 7, not shown) of a motor 26 which drives via a belt 28 the meshing gears 18, 10 whereby the operator is prevented from reaching into the meshing area of the pair of gears while the machine is running. As shown, the machine is such that the pinion 18 and crown wheel 10 are carried on crossheads 22, 14 movable on slides at right angles to each other, the pinion 18 being initially moved by hydraulic actuation of the crosshead 14 into initial mesh with the crown wheel 10 on the crosshead 14. The crosshead 14 is then manually moved by a coarse adjusting handwheel 40 via a worm shaft 34 to move the crown wheel 10 into the true theoretical meshing position which may be readily determined by a scale 48, 50, 52, on the hand wheel 40. The final, i.e. noise level testing adjustment is effected by the fine adjustment handle 42 which has a split spring loaded hand grip 64, 66 which when gripped by the operator's left hand secures, via a friction clutch bond 78, the handle 42 to the worm shaft 34 and at the same time closes the switch 76 of the motor circuit. Closing the final switch 90 (or 90<SP>1</SP> for reverse drive) by the operator's right hand starts the machine motors 26 to run the gears 18, 10 which via the fine adjustment handle 42 may be adjusted to determine the minimum noise level, the adjusted reading being recorded and used when installing the gear set in a motor vehicle differential assembly.

Title: Improvements in and relating to coating apparatus
Inventor: JONES SAMUEL HAYDN
IPC: B05C19/02
Filed: 1964-09-24
Abstract: Apparatus for coating articles with a thermosetting or thermoplastic coating fluid comprises means for conveying said articles in succession to each of plurality of work stations, together with means at each station for immersing the article in said fluid for a predetermined period and for thereafter heating the article.  The article may also be heated prior to entering the first work station and may pass through a heated enclosure subsequent to leaving the last work station.  In Fig. 2 work holders 30 are carried by supports 24 on conveyor chain 23 which passes around sprockets 21, 22, the latter being driven intermittently by pneumatic cylinder 25.  The work holders each supporting an article to be coated pass first through heating station 40, 41 to station 42 at which there is a receptacle 43 for powdered resin which is maintained in a highly fluid state.  When an article is in position at station 42 receptacle 43 is raised by a pneumatic actuator (47) so as to immerse the article in the fluidised coating material.  After a predetermined interval the receptacle 43 is lowered and induction heating coils 48 are moved inwards by pneumatic actuators (49) adjacent the coated article. At successive stations 50, 51, 52 and 53 which are generally the same as station 42 the article is successively coated and reheated.  Finally the article passes through elongated curing oven 54 back to the loading position 33.  The work holder 30 is secured to support 24 by a reflex spring member which allows oscillatory movement of the work holder and electromagnetic means are provided to oscillate the work holder to shake off excess coating.  The holder 30 (Figs. 7 to 10, not shown) consists of a back plate (120) with a spring loaded U-shaped clamping member (31) pivoted thereto and additional masking clamping jaws (32, 32a).  Operation of the work holder is effected by appropriate cam means.  The coating material receptacle (Figs. 11, 12, not shown) may be a single semi-circular receptacle (140) covering all the work stations and having dispensers (144) feeding thereinto with overflow weirs (145) or alternatively there can be separate receptacles at each station.  Suitable means for controlling and interlocking motions of the conveyor, the receptacles and the heating means may be provided.

Abstract: 391,320. Moulding concrete blocks &c. SCHAEFER, W., L.14.11, Mannheim, Germany. May 17, 1932, No. 13965. [Class 87 (ii).] In concrete block or slab-making machines, of the kind in which solid or hollow blocks are made with or without tensioned reinforcement in successive superposed layers with paper or like separating sheets by means of a travelling bogie carrying the feeding hopper and the tamping-mechanism, the sides of the mould and the cores for forming hollow blocks, or both, are carried on the bogie and are moved forward intermittently with intervals of rest at a rapid pace in comparison with the uniform slower forward movement of the bogie. The concrete hopper 2 and tamping-machine 1 are mounted on a trolley 5 which can move laterally in the bogie frame 3 to position them over any one of a number of rows of moulds 46. As the bogie passes from left to right in Fig. 2 over the long mould bed the following operations are performed. (1) A layer of concrete is delivered from the hopper 2 on to the mould base, the quantity being regulated by the adjustable door 8. (2) Tamping arms 9 driven from the motor 10 level and compress the layer. (3) A layer of fine cement 16 is applied for surfacing and is smoothed by the member 17. (4) A set of reinforcing wires 53 is drawn from the reels 33 by the moving bogie to be embedded in the blocks of the next higher layer. Suitable guides, weight-tensioning means and clamps are provided to maintain the wires in tension during the idle return run of the bogie. (5) Two sets of round or oval core-pieces 28 are moved forward alternately at intervals with a jerky motion relatively to the bogie by cam mechanisms in order to form the holes in hollow blocks. The grooves made by the suspending bars 21, 22 of the plungers are tamped out by the rearward tamping-arm 9. After each layer of blocks is made, a layer of paper is laid between it and the next superposed layer. In some cases, the side walls of the moulds may move with the bogie and have a similar jerky movement to that imparted to the core-pieces.

Abstract: 1,191,328. Anti-skid systems. MULLARD Ltd. 21 June, 1968 [4 Sept., 1967], No. 40348/67. Heading F2F. [Also in Division G1] In an anti-lock brake system, wheel movement is sensed by a pick-up whose output is converted to a D.C. signal of substantially constant amplitude for all speeds at and above a preset minimum. A brake release system is actuated in response to a change in the D.C. signal caused by a reduction in the wheel speed below the preset minimum means being provided for limiting the time during which a release current is allowed to flow. As shown, the electromagnetic pick-up produces a substantially square-wave signal which is fed to the bases of transistors T1, T2 of an amplifier and amplitude limiter. The outputs at the collectors are fed via capacitors C1, C2 to transistors T3, T4 which rectify and limit the signal which is smoothed by capacitor C3. If the wheel speed falls below the preset minimum so that the pick-up output is nearly zero, T3 and T4 become non-conducting and the voltage at their collectors swings positive at a rate determined by R9, R13 and C3. This voltage swing draws a current through capacitor C4 which switches on transistors T5-T7 controlling a solenoid of the anti-lock brake system causing the brakes to be released. The duration of this current depends on the magnitude of the voltage swing determined by diode D1 and potential divider R11, R12, and the time constant of C4. A delay, produced by a capacitor C5, may be provided in de-energizing the solenoid, the value of C5 being dependent upon the inertia of the wheel and the speed of response of the mechanical servo which modulates the brake pressure. For a four wheel vehicle, a separate system, as above, may be provided for each wheel or alternatively one each for the front wheels and a common one for the back wheels. The antilock device may be as described in Specification 1,101,078 or Specification 1,183,706.
