Title: Improvements in electrically operated indicators for theatres, picture palaces and the like
IPC: G09F11/02
Filed: 1922-07-01
Abstract: 204,148. Lawson, C. July 1, 1922. Rotary cylinder, prism, and like apparatus; rotary apparatus, internally illuminated; reel and endless-web apparatus.-In electrically-operated indicators for theatres and other places in which a prism or endless band bearing information is driven by a motor controlled by switch and commutator mechanism, the prism is adapted to rotate through the angle subtended by only one panel for each manual operation of a switch. The prism A is provided with connected contacts H' at its corners which when touching a contact J<1> on a leaf spring J complete the motor circuit through the bearing B<1> or through a second commutator spring. The contact J' is not long enough to bridge the distance between two contacts H<1>, consequently the prism stops as the contacts J<1>, H<1> separate, the pressure of the spring J assisting in registering the displayed panel. To advance the prism another step, a selfopening shunt switch L is manually operated till the next contact H<1> reaches the contact J<1>. Removable cards may be held by clips A' on the prism A, or the prism may have transparent walls, or be of skeleton formation and fitted with changeable transparencies, and be internally illuminated. The prism A may form one roller for an endless band which may be transparent and be illuminated by transmitted light.

The carrier is reciprocated by a roller 17, Fig. 1, carried by chains 15 forming part of the gearing of the machine, the roller engaging top and bottom slots in a bracket 18 secured to the carrier. The material is clamped by a bar 68 carried by sleeves 71 which can be clamped in any position on uprights 67. A modified clamping bar is shown in Fig. 9, this having pins 81 carried by a bar 79 supported by rollers 78 which can be depressed by eccentrics 77 to cause the pins 81 to project considerably and firmly hold small pieces of material. For slice feeding, a feed-screw is turned by a lever 34, Fig. 3, carrying a pawl engaging a ratchet-wheel on the screw, the lever being engaged by a fixed cam 35 as the carrier reciprocates. For regulating the thickness, the return of the lever is limited by an adjustable stop 37. For cutting thicker slices, an adjustable member 46 is brought into the path of a second lever similarly driving a spur-wheel gearing with a pinion on the feed-screw. The nut on the feed-screw is made in two parts normally pressed towards the screw by springs but withdrawn by cams when it is desired to move the carrier along the screw. A knife-sharpener comprises two stones e, f, Fig. 8, pressed towards each other by springs and pivoted on a spindle p. A flat spring r has its end aslant to tend to push the stones about the spindle p out of contact with the knife and also to press the stone e towards the knife when the whole device is pulled into contact with the knife by a rod t, Fig. 1. The rod t may be automatically pulled and released by a pawl z, Fig. 11, on a lever y engaged by the bracket 18 as this reciprocates, the pawl z engaging a ratchet-wheel secured to a cam dd having a pin ff engaging a hooked member cc which moves the rod t to bring the sharpener into position. The ratchet-wheel is turned until the pin ff pulls the sharpener into position. Shortly afterwards, the cam dd lifts the member cc and allows the rod t to return and the sharpener to move out of contact with the knife. A metal sheet acting as a slice guide has a portion c, Fig. 1, adapted to scrape the knife. A pad 90 of rubber or felt may clean the knife edge.

Abstract: 1371887 Flash apparatus POLAROID CORP 18 April 1973 [24 April 1972 5 Feb 1973] 18745/73 Heading G2X An adapter for a camera having a flash circuit calibrated for firing flash lamps of a given impedance includes switching means responsive to a lamp firing signal to provide an actuating signal for an electronic flash unit, the adapter presenting during such operation an impedance equivalent to that of a flash lamp. Fig. 2 (not shown) sets out the details of a flash lamp firing circuit for firing in sequence a series of three flash lamps (60a, 60b, 60c,). When a lamp fires successfully, a predetermined impedance is sensed by a monitoring unit, which presents a signal activating a fixed delay and inhibiting a lightsensitive circuit which controls the exposure under ambient light conditions. Fig. 4 shows an adaptor arrangement for actuating an electronic flash 178, and which connects with the flash lamp firing circuit 40 at terminals 182, 184. The corresponding leads 186, 188 are inter-connected by a reed-type relay 190 which represents an inductive load. A fixed resistor 196 is also coupled across leads 186, 188 in parallel with relay 190, this resistor having an impedance characteristic closely similar to those of the flash lamps. Thus as the firing circuit is energized, relay 190 is energized to close a switch 192 which closes the circuit to the electronic flash 178. This is. detected by the monitoring unit as a successful flash ingition, which presents a signal as before.

Abstract: 703,224. Ratchet gearing. HARD, C. G. July 25, 1952 [May 16, 1952], No. 18881/52. Class 80 (3) In a ratchet gear device in which two or more driving units operate on the same driven element means are provided for adjusting the working phase of one or more of the units in dependence on the working phase of one or more of the other units. As shown, four separate driving units 6, 7, 8, 9 operated by fluid-pressure impulses work in pairs 6, 8 and 7, 9 for driving a ratchet wheel 14 through spring-loaded pawls anti-clockwise or clockwise respectively. The two units of each pair may operate simultaneously to give a greater driving force or alternately to give a lesser driving force but a greater rate of rotation of the driven wheel 14 under control of devices 19 and 20 showm in more detail in Fig. 2. These devices each comprise a spring-loaded piston valve 26 subjected at one end to the pressure in the associated driving unit from pipes 21 or 22 and having lands 31, 32, 33 controlling the pressure fluid from an inlet port 34 to an outlet port 35 leading to the ether driving unit through either of passages 37 or 38 as controlled by a changeover valve 36. With the valve in the position shown port 34 is put into communication with port 35 only when pressure is supplied to the end of piston 26 from pipe 21 or 22 so that both driving units will work in phase. In the other position of valve 36 pressure is only supplied -to port 35 when the fluid-pressure on piston 26 is released so that the two driving units operate alternatively. A port 39 is provided for the exhaust of the fluid-pressure from the port 35 on completion of a stroke of the associated driving unit. The pair of driving units for one direction may be adjusted to operate with greater force at low speed whilst the pair for the opposite direction may operate with a smaller force at greater speed. Also the valve 36 may be set to cut out the second driving unit completely if desired. Pawls 45, 46 coupled to the pairs of driving units through linkage 42, 43, 44 may be provided to prevent backward running of the wheel 14 according to whichever direction the wheel is being driven. A manual operating lever 50 for setting either of the pawls 45, 46 in a blocking position or both in a neutral position as desired. The driving units 6, 7, 8, 9 may be electrical or mechanical mechanisms instead of hydraulic or pneumatic and may be other than the reciprocating type. Any number of driving units may be utilised.

Abstract: 1,056,006. Recording-apparatus. F. SCHWARZER. May 5, 1965 [May 6, 1964], No. 18907/65. Heading G1J. [Also in Division H1] Recording-apparatus comprises an electrosensitive recording medium a and a layer d of photo-sensitive resistance material with one side in electrical contact with the medium a and the other side kept at a different potential from the medium a by a source k so that upon illumination of a spot of the layer d by a beam of light from a tube i, the resistance of the spot drops and current passes to the medium a to record a trace. The layer d may be carried by a sheet of glass f with a thin layer e of transparent conductive material between, connected to the source k and with a thin layer c of high resistance material to protect the layer d mechanically from abrasion by the medium a and electrically from overloading, while keeping the record sharp. The spot of light may be deflected in two co-ordinate directions to record lissajou figures on a stationary medium a or the spot may be deflected transversely to the direction of movement of the medium a. For the latter purpose, the layer d may be reduced to an elongated strip along which a light spot is deflected by a galvanometer mirror, Figs. 2, 3 (not shown). In a modification, Fig.4 (not shown) an assembly of lamellae s in contact with the strip d have points arranged to form a recording edge, the lamellae having high conductivity in a longitudinal direction, and high resistance transversely. The thickness of the lamellae together with the insulating layers therebetween is made small enough for a suitably focussed spot of light to illuminate at least two lamellae at a time.
