Title: Improvements in and relating to cinematograph apparatus
Inventor: TOLE DONALD KENNETH
IPC: G03B19/18
Filed: 1959-09-22
Abstract: 959,197. Cinematographic apparatus. SPECTO Ltd. Aug. 22, 1960 [Sept. 22, 1959], No. 32227/59. Heading G2E. A cinematographic camera or projector having two film frame speeds and claw feed mechanism has a registering pin for engaging the film perforations when the feed claw is retracted from the film. The embodiment of Fig. 1 is a camera having an objective 11 and an additional housing 12 for a cathode-ray tube the image on which is photographed simultaneously with the main object with the aid of a beam combining element 14. The electric motor 20 drives,via pinions 21, 22, an overload slipping clutch 23 and further pinions 24, 25, a one-revolution clutch 26. The latter may be coupled, against disengaging spring-loading 31,to the shaft 30 by an electric pulse which, as explained below, is applied at predetermined intervals to a solenoid 32. The armature 33 of the latter is linked via members 34, 35, 36 to the one revolution clutch, thus rotating drive shaft 30 with a speed reduction factor of 15. The pulses to the solenoid are controlled by a pair of series-linked switching drums 43, 50 which are of insulating material and carry a conducting strip for bridging respectively the pairs of conducting strips 45, 52 once each revolution, and which are driven from the gear train at speeds of one revolution per second and one revolution per 15 seconds, respectively, so that the make-and-break is carried out rapidly once every fifteen seconds. Fig. 2 shows the claw mechanism mounted on a housing 61 which is slidable by means of an eccentric 72 towards and away from the film gate. Claw arms 62 having claws 68 for engaging the film perforations are pivotable on an axis shaft 63 reciprocable in slots 64 by crank 65 the shaft 66 of which rotates twice as fast as a shaft 76 (both these shafts being driven via suitable gearing from drive shaft 30). Shaft 76 drives a double cam 75 to rock a spring-loaded lever 77. A pin 78 on the latter slidably bears on claw arm 62 and pivots it, without interfering with the downward movement of the pivoting axis 63, thereby disengaging the claws from the film and at the same time pushing a registering pin 81 into engagement with a perforation in the film. Specification 959,198 is referred to.

Title: Fluid pressure control apparatus for regulating the speed of variable speed internal combustion engines
IPC: F02D1/00
Filed: 1957-10-16
Abstract: 850,547. Fluid-pressure servomotor-control systems. WESTINGHOUSE AIR BRAKE CO. Oct. 16, 1957 [Oct. 16, 1956], No. 32326/57. Class 135. Fluid-pressure apparatus regulating the fuel supply and speed of an I.C. engine comprises a double-acting actuator 7 responsive to differential pressure to vary the fuel supply or maintain a given supply when the pressures are equal, operator-controlled valve means 3 for selecting a pressure for a desired speed, engine-speed responsive valve means 4 controlling the opposing pressure in accordance with actual speed, and means 5, 6 responsive to reduction of one of the opposing pressures below a certain low valve to cause the actuator to shut off fuel supply. Initially compressed air at 2 passes open valve 61 to shift valve 67 to the left and, together with spring 13, moves diaphragm 7 and fuel supply control rod 12 downward to fuel off position. The air also passes open speed controlled valve 24 to load diaphragm 54 downwards with a pressure of 10 p.s.i. to close valve 61 and open vent valve 64 so that valve 67 moves to the right. At a pressure of 15 p.s.i. speed and manual-controlled valves 24 and release valves 28 are closed by their diaphragms 15 so that air at this pressure is trapped in both pairs of chambers 20, 22, pipes 23, 36 and the chambers 9, 10 on either side of diaphragm 7. To start the engine, handle 31 is moved to the left so that cam 32 loads spring 30 and opens valve 24 so that air passes to the chamber 9 and lifts diaphragm 7 and rod 12 to maximum fuel supply position. The handle 31 is then moved to set a pressure in chamber 9 corresponding to a required speed and the engine-driven centrifugal governor 38 produces a corresponding pressure in chamber 10 via its spring 30 and valve 24 to balance the pressure in chamber 9 and hold the rod 12 in a position to maintain the required speed. If the load increases, the speed decreases and governor 38 opens its release valve 28 to reduce pressure in chamber 10 to increase the fuel supply and maintain the speed set by handle 31. With decrease in load and increase in speed, the governor opens its valve 24 to increase pressure in chamber 10 to reduce fuel supply to keep the speed constant. Should governor valve 4 fail, e.g. by rupturing diaphragm 19, pressure falls in pipe 36 and diaphragm 54 rises to close valve 64 and open valve 61 so that pressure at 2 shifts valve 67 to the left and rod 12 to fuel off position. In an alternative embodiment, air from the manuallycontrolled valve loads a diaphragm which closes the speed-controlled air supply valve on a spring- loaded vent valve and the governor acts directly on the valves through a rod.

Title: Process for the manufacture of condensation products from substitution products of 2.3-hydroxy-naphthoic acid
Filed: 1935-11-26
Abstract: Derivatives of nuclear substitution products of 2 : 3-hydroxynaphthoic acid are manufactured by reacting a nuclear substitution product of 2 : 3-hydroxynaphthoic acid with anthranilic acid amide or a substitution product thereof in the presence of a dehydrating agent in an indifferent medium, or by first reacting the chloride of the acid with the anthranilic acid amide to produce a 2 : 3-hydroxynaphthoylanthranilic acid amide and effecting ring closure by heating the amide alone or in an indifferent agent, with or without a condensing agent, or by treating it with a caustic alkali lye.  In examples: (1) 6-methoxy-2 : 3-hydroxynaphthoic acid is converted, by the action of thionyl chloride in toluene, into its chloride, which is heated with anthranilic acid amide to produce 6-methoxy-2 : 3-hydroxynaphthoylanthranilic acid amide, ring closure of which is effected by heating with aqueous caustic soda; there may similarly be obtained condensation products of anthranilic amide with 7-methoxy-, 6-methyl-, 6-bromo- and 7-chloro2 : 3-hydroxynaphthoic acid, of 2-amino-4-methoxybenzamide with 6-methoxy-2 : 3-hydroxynaphthoic acid and of 4-methyl-2-aminobenzamide with 7-methoxy-2 : 3-hydroxynaphthoic acid; (2) 8-nitro-2 : 3-hydroxynaphthoic acid is heated with anthranilic acid amide in toluene in the presence of phosphorus trichloride.  Specification 445,857 is referred to.  2 - Amino - 4 - methoxybenzamide is obtainable by transforming 1-amino-2-nitro-4-methoxybenzene by the Sandmeyer reaction into the 1-cyano-compound, reducing the nitrogroup with iron and acetic acid and saponifying the cyano group with hydrogen peroxide and caustic soda in dilute aqueous alcohol.

Title: Improvements in counters
IPC: H03K23/76
Filed: 1954-11-12
Abstract: 756,908. Circuits employing multi-stable ferroelectric elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 12, 1954 [Nov. 17, 1953], No. 32809/54. Class 40 (4). [Also in Group XIX] A counter comprises a ferroelectric capacitor capable of assuming a multiplicity of stable states of polarization between two limits, means for polarizing the capacitor to one of the limiting states, means for applying information representing quantified pulses to the capacitor to cause it to exist at an intermediate state between the limits, and means for producing an indication of the information stored. Positive input pulses on a lead 14, Fig. 2, are standardized in amplitude and duration by a device 15 so that a pre-arranged number n-1 of such pulses are required to cause complete reversal of polarization of a ferroelectric storage element 10 from state b, Fig. 1, to state a. During the first n-1 pulses insufficient voltage is developed at the point 11 to affect a one-shot multivibrator 17, but the element 10 presents only a low capacitance to the nth pulse, and sufficient voltage is then developed to trigger the multivibrator 17 and produce a single output pulse on lead 18. This pulse is also applied to a cathode follower 19 which supplies a pulse to the opposite plate of the capacitor 10 sufficient to return the element to its initial state b of polarization. In an alternative arrangement, instead of returning the ferroelectric element 20, Fig. 3, to its initial state, the nth pulse reverses a bi-stable flip-flop 23 which, through lines 32, 33, reverses the bias on diodes 28, 30 to cause subsequent input pulses from a quantifying circuit 36 to be applied to the opposite side of the ferroelectric element 20 and, so step the polarization in the opposite direction. The 2nth pulse returns the input pulses to the initial channel, and so on. Subtraction and addition can be performed by selectively applying input pulses to the upper -and lower plates respectively of the ferroelectric element. Various methods of reading out the stored amount are described including " rolling out " by applying a series of n pulses, or applying a large pulse and observing the voltage developed across resistor 13, Fig. 2. Fig. 4 shows a pulse quantifying circuit. A bias 54 normally holds a ferroelectric capacitor 50 in a polarization state d, Fig. 1. A positive count pulse, applied to terminal 51, drives the capacitor 50 to state c. At this time, a predetermined quantified pulse is developed due to the flow of electrons from a condenser 55 towards the point 52. This positive pulse passes a diode 56 and is applied to a counter of the type described above. At the termination of the input pulse, current flows through a resistor 53 to recharge the capacitor 50 in its opposite limiting sense.
