Title: Improvements in or relating to the manufacture of films and foils or the like
IPC: B29C41/24
Filed: 1929-02-18
Abstract: 332,254. Frenkel, G. Feb. 18, 1929. Coating non-metallic surfaces with metals.-A carrier surface for use in a machine for making films is made by flowing a plastic material on to a drum or band preferably of metal and then depositing metal on the plastic material so as to form a smooth metallic surface for the reception of the film forming solution. If desired, the carrier-surface with its support of plastic material may be removed from the drum or band on which it has been formed, and used as a substitute for the usual copper band employed in machines of this type, or be placed over another drum. The plastic material may be a cellulose derivative such as cellulose acetate, or a synthetic resin, indiarubber, or gelatine, and the metal may be sprayed thereon in powder form in a solvent for the base, the evaporation of the solvent leaving the mteal as a surface coating sticking to the plastic mass. Alternatively, the metal may be applied whilst the plastic mass is still tacky but not liquid, or the metallic surface may be produced by condensation methods from the vapour of the metal. Before use, the meal surface produced is preferably given a high polish. The base layer may have substances such as castor oil incorporated with it to give flexibility; it may be of composite nature and be formed by superposing a plurality of foils of which the first foil forms the carrier surface for the subsequent foils.' The metal surface is readily repairable, for a damaged portion could be cut out and a new section formed in accordance with the invention so as to restore the smoothness of the surface. Specification 332,255. [Class 2 (ii), Cellulose &c.], is referred to.

Title: Improvements in the remote control of cranes
IPC: B66C13/40
Filed: 1954-02-26
Abstract: 763,173. Electric control systems. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. Feb. 26, 1954 [March 14, 1953], No. 5694/54. Class 40 (1). A crane is controlled directly from the usual craneman's cabin, or is remotely controlled by different audio-frequency electric signals, one for each control, transmitted over sliding contact conductors. Transmitter, Fig. 3. Three thermionic oscillators 5, 6, 7 capable of generating five different frequencies are shown for controlling the speed and direction of the crane hoist motor, the arrangements disclosed being duplicated as necessary for other crane controls. Oscillator 6 generates at one frequency, but each of oscillators 5, 7 generates at either of two fixed frequencies dependent on whether or not an additional capacitor 44 is connected in the oscillator circuit. A controller 15 is selectively operated to close one or more of five contacts 39 ... 43 whereby the appropriate oscillators are energized to develop the corresponding audio frequencies which are each passed over a coupling resistor 10, an amplifying and matching regulating stage 12-for removing unwanted parasitic frequencies-and over the lines 13-14, one of which may be a crane power line, to the receiver. Contact 41 may, for example, select oscillator 5 at frequency fa to start the hoist motor upwards, contacts 41-43 operated together may select oscillator 5 at frequency #b to start the motor downwards, the motor speed being increased in steps by contacts 40, 42, 39 operating oscillators 7, 6, 7 selectively at frequencies #c, fd, fe to effect sequential increases in the hoist motor speed. Further control frequencies may be used for additional speed control steps. Fluorescent lamps 8 light up to indicate when their associated oscillators are active. Separate oscillators may be used for each control frequency or a single oscillator may be used to function at different set frequencies to start the hoist motor up or down, speed control in the latter case being effected by automatic sequence switching under time control. Two or more cranes travelling e.g. on the same rails may be similarly controlled, the set frequency values used for the two cranes being interlaced. One control frequency may be used for operating an emergency stop switch. The crane may be controlled also from the craneman's cabin in the usual manner, there being a switch for changing from one to the other control. Receiver, Fig. 4. The audio control signals over lines 13-14 are amplified at 25 and passed selectively by filters 30a, 30b ... 30e, through rectifiers 31a ... 31e to actuate relays 32a ... 32e corresponding to the transmitted frequencies. These relays preferably through auxiliary relays 33a ... 33e effect the control of the hoist motor in known manner over lines 34a ... 34e. The control and auxiliary relays may be dispensed with. The amplifier 25 may be cut out automatically during idle periods.

Abstract: 1283685 Bowling ball return mechanism AMF Inc 19 April 1971 [6 March 1970] 5780/ 70 Heading A6D A ball return mechanism in a bowling alley, situated in a cavity between the side walls of the pit ends of adjacent bowling lanes, each pit end having two such side walls one of which has an opening in it for the ball to pass through, consists of a return track, disposed at or below the level of the lane bed on which a pin P is shown in the Fig. and an accelerator which engages the ball and accelerates it along the track. In the embodiment shown there are openings 15 and 16 from adjacent lanes into the cavity, the ball being passed through an opening 15, 16 from a conveyor 12, being helped through by a rotating wheel or kicker 88, 89, the ball landing on guides 92 with a central block 93. The ball is now raised by an elevator belt 35 contacting the top of it, this raising it over a block 98 from which it runs down guides 100, 101 to be contacted by the belt 105 which is moving so as to accelarate the ball along the return track. Movement against springs of the kickers and the elevator belt allow the accommodation of different sizes of balls. A paddle 17 on an arm 72 moves laterally between a position in which it closes one of the openings 15 and 16 to a position in which it closes the other, this paddle preventing pins from entering the cavity or rejecting any which have entered. The elevator belt 35 is driven by two motors 19, 20, one associated with each lane, only one being used if only the one lane is in use. The cavity in which the assembly is accommodated is in a hollow between the two kickbacks K between the lanes, the side plates 10 abutting the rears of these kickbacks. An alternative embodiment has two accelerator belts to accelerate the balls in two stages to lessen the chance of the ball being damaged by frictional engagement with the belt. The ball elevator and accelerator can also be in the form of wheels.
