Title: Apparatus for the Projection of Transparencies in Synchronism with the Playback of a Record
IPC: G03B31/06
Filed: 1966-09-08
Abstract: 1,155,045. Disc records including transparencies; playback and projection apparatus. STAAR DEVELOPMENT CO. S.A. 8 Sept., 1966 [10 Sept., 1965], No. 40104/66. Heading G5R. The invention provides a gramophone record comprising a series of transparencies arranged around its periphery, and a groove having a first flank modulated for sound and a second flank provided with deformations adapted to control projection or erasure of an image of one of the transparencies. The invention also provides apparatus for the projection of the transparencies in synchronism with the playing of the record, including a pick-up arm bearing a stereophonic-type pick-up head and a projection system for projecting an image on a screen; the deformations in the second flank produce signals which actuate means to control projection or erasure of the image; some of the signals picked up from this second flank correspond exactly to the angular dispositions of the transparencies. As shown, one side of a stereophonic-type groove on a disc record 3 has sound modulations which are reproduced by an amplifier 35; the other side has, at precise locations, deformations of two kinds which control optical apparatus 21 to 34. When one deformation of the first kind passes under pick-up head 9, a pulse is fed via leads 19, 20, an electronic separator 31 and a relay 30 to an electromagnet 27, whereby a flap 25 is withdrawn for a very short interval radially outwards to permit light from a projector 23 to pass through an aperture 26 in the flap and through a transparency located in the edge of the record 3 and disposed, at that instant, under aperture 26; the image of the transparency is reflected by mirror 22 on to a screen having residual luminosity. Further deformations of the first kind are provided in a number (e.g four) of subsequent grooves so that the transparency will be projected four more times. In the same groove as the last of these particular deformations of the first kind, a deformation of the second kind is provided, the signal from which is passed by the electronic separator 31 to a relay 33 controlling a lamp 34, the radiation from which falls on screen 31 to erase the transparency image. The same or a subsequent groove of the record bears another deformation of the first kind located so as to operate the projector when a different transparency is in position under aperture 26, and the above cycle is thereafter repeated for this transparency. A plurality of images may be projected successively to form a single or moving image. The flap, electromagnet 27 and projector lamp may be replaced by an electronic flash triggered by the pulse.

Title: Electrostatic spray gun incorporating a safety device
IPC: B05B5/10
Filed: 1973-09-05
Abstract: 1438528 Electrostatic spray guns ATLAS COPCO AB 5 Sept 1973 [14 Sept 1972] 41682/ 73 Heading B2F [Also in Divisions H1 and H2] An electrostatic spray gun 10 has an earthed handle 11 of electrically conducting material, a plastics barrel 41, and a changing electrode 40 for paint in the form of a powder or a liquid connected to a high voltage source 30 through a shielded cable 19 having a central insulated lead 20 connected to the electrode 40, the shield 21 being earthed and connected to said handle, and also has a safety device comprising a control lead 27 connected to the handle at a point separate from the connection of the shield 21 to the handle and a control means is connected to the control lead and shuts off the high voltage supply to the electrode when the control lead is disconnected from its earth connection via said handle. Means is provided to sense the electric potential in said control lead. The components provided to control the high voltage supply to the electrode 40 comprise a transistor 35 connected between a voltage source and earth as a switch for the high voltage supply, the base 36 of the transistor beinig connected to the handle 11 via the control lead 27, said control lead being also connected to a low voltage source, located in the control unit 31, via a high resistance 39 e.g. 5-15 kiloohm. The transistor 35 controls a relay 33 which is part of the high voltage source feed circuit. Around the shield 21 of cable 19 is an insulating and protecting cover (26), Fig. 2 (not shown), helically encircled by the control lead 27 which is surrounded by outer cover 28. A small current flows through the circuit comprising the low voltage source, the resistor 39 the control lead 27, the end plate (16), Fig. 2 (not shown) of the handle 11 and the earthed shield 21 of cable 19. If the connection to earth of the control lead 27 through handle 11 and shield 21 is broken, the base 36 of the transistor 35 will be at positive potential with respect to the earthed emitter 37, so the transistor will be conductive and relay 33 will switch off the feed circuit of the voltage source 30 to the electrode 40. Compressed air is supplied to the gun through a hose 13 to a control valve having an actuator 12 which when opened supplies air to a control hose 14 leading to a powder supplying unit. This unit provides the gun with a suspension of powder and air via a supply hose 15.

Title: Drive mechanism
IPC: F15B15/20
Filed: 1971-09-08
Abstract: 1357968 Fluid operated drive mechanisms D WEISS 8 Sept 1971 [29 April 1971] 41807/71 Heading F1D A fluid operated drive mechanism comprises an output member in the form of a sleeve 13 operated by pistons 5, 9 such that a first part of the stroke provides a low force output over a relatively large distance and a second part of the stroke provides a high force output over a relatively short distance, this second part being effected by increasing the mechanical advantage between the piston 5 and sleeve 13. Piston 9 is a collar on a rod 10 which has a shoulder 12 engaging a collar 14 on sleeve 13, and piston 5 is annular and slidable relative to rod 10 on which it is sealingly mounted. Attached to piston 5 is a conical sleeve 7 which is for engagement with rollers 23 of transmission members 17 mounted on sleeve 13. Each member 17 comprises a bent lever 18 mounted pivotably about pin 20 in a slit 16 in sleeve 13. The lever 18 is forked and receives roller 23 which is mounted in the fork on pin 24. Lever 18 has a bearing surface 22 for engagement with the bore 2 of cylinder 1. Bore 2 opens into a widened cavity 28, a conical surface 27 joining the coaxial cylindrical surfaces of bore 2 and cavity 28. Thus, if fluid-pressure is admitted through inlet 29 then the pistons 5 and 9 clearly move together and take sleeve 13 with them. However, when the bearing surfaces 22 reach conical face 27 the wedge-shape conical sleeve 7 can act on rollers 23 to urge surfaces 22 down the surface 27, the piston 5 consequently leaving piston 9 and the mechanism coming eventually to the end of its stroke as shown in the right hand side of Fig. 1. Clearly, the action of piston 5 and wedge 7 on transmission members 22 increases the mechanical advantage between the piston 5 and sleeve 13 over the second part of the stroke. The sleeve 7 has intermediate cylindrical surfaces 31, 33 alternating with conical surfaces 30, 32 so that if fluid-pressure ceases to be transmitted the mechanism will be held with the rollers 23 engaging the cylindrical surfaces 31 or 33 since in this position there is no tendency for the sleeve to react against the rollers and be returned to its initial position. This "locking" affect can be improved by replacing the cylindrical surfaces by appositely directed conical surfaces Fig. 2, (not shown).

Title: Treatment of molten metal
Inventor: WILLIAMS FREDERICK GEORGE
IPC: C21C7/00
Filed: 1962-11-09
Abstract: In a process for treating molten metal involving blowing a stream of gas downwardly on to the surface of the molten metal or of a slag layer floating on the molten metal from a nozzle above the surface, the flow of gas to the nozzle is caused to pulsate regularly, preferably by operating a valve located in the gas supply line to the nozzle using a cam to interrupt the gas flow at regular intervals, e.g. 12-600 pulsations per minute, whereby the gas stream striking the surface varies regularly in velocity. Alternatively, the gas may be supplied by a low-speed reciprocating pump.  The process may be applied to dephosphorizing molten iron using a slag, powdered lime being supplied dispersed in a stream of oxygen, or refining iron and steel by blowing an inert gas containing powdered desulphurizing or carburizing agent in suspension. Powder suspended in the gas stream may be introduced before the pulsations are introduced, but preferably a steady gas flow containing powder in suspension is maintained through one tube of a multi-tubular lance, pulsations being introduced into the flow of powder-free gas through another tube. Nonferrous metals may also be treated.
