Title: Improvements in or relating to draughting-machines
IPC: B43L13/08
Filed: 1939-09-27
Abstract: 533,594. Draughting machines. DARGUE, A. W., and DARGUE, E. L. Sept. 27, 1939, No. 26701. [Class 97 (iii)] The head of a draughting machine of the parallel link type comprises a stop plate a pivoted at a<SP>1</SP> to the junction plate b. A screw a<SP>3</SP> extending through a central hole in the stop plate a has mounted loosely upon it the scale carrier f and the protractor plate h. The plate h is secured to the carrier f by screws s which pass through ah arcuate slot i<SP>1</SP> in the stop plate, distance pieces being arranged in the screws s to hold the protractor plate h and scale carrier f clear of the stop plate a and permit rotation. The stop plate a has a portion of its periphery provided with spaced notches or teeth a' with which a tapered nose j<SP>2</SP> on a pivoted pawl j may engage under the influence of a spring-pressed slide h. The pawl j may be withdrawn and held clear of the teeth a<SP>7</SP> by a finger tail and a plunger. Markings on the protractor plate and a carrier n<SP>1</SP> permit finer adjustments, a clamp n<SP>2</SP> being provided to secure the protractor plate to the stop plate a. The scale carrier f has arms provided on their underside with undercut longitudinal grooves adapted to engage longitudinal tongues g<SP>1</SP> on the scales g. The base of the grooves f<SP>2</SP> are slit at f<SP>3</SP> and right and left hand screws f<SP>4</SP>, f<SP>5</SP> are provided to enable the grooves f<SP>2</SP> to be widened to permit the tongues g<SP>1</SP> of the scales to move easily therein reversal of the screws allowing the sides of the grooves to grip the tongues and so secure the scales g. The stop plate a may be adjusted to the junction plate b by means of a screw c passing through an aperture in the stop plate a and through a concave conical ring d carried by the stop plate a. A conical nut e is rotatable on the screw and engages one side of the conical cavity in the ring d, the conical cavity being of greater diameter than the nut. A spring d<SP>2</SP> aids the nut to bear against the side of the conical cavity. Screwing in or out the nut adjusts any error of alignment of the scales g.

Title: Improvements in and relating to fault detecting and cutting out systems for electricsupply circuits
IPC: H02H3/17

Abstract: 444,399. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and BUTLER, F. E., 74, Eastlands Road, and JEWITT, D. E., 17, Hillmorton Road, both in Rugby. Sept. 19, 1934, No. 26934. [Class 38 (v)] Apparatus for detecting and cutting out faults in supply systems consisting of a number of circuits, particularly on ships, where insulation failures are frequent, comprises a relay Y connected to the supply mains and adapted to be operated by the occurrence of a fault to complete the circuit of a motor M, which drives a generator G to apply a testing current to the circuits in turn and automatically cuts out the faulty one. Two power circuits are shown connected by solenoid-operated contactors K, with overload relays L, to bus-bars N, across which is a resistance having its mid point earthed through the coil of the relay Y. An insulation fault on a conductor or conductors causes the relay Y to start the motor M which drives the generator G and also a multi-contact switch, which has a set of three contacts A .. C for each circuit and, by its rotation, causes each circuit to be opened in turn at A and a testing current to be supplied from G to each opened conductor in turn over contacts B, C. If there is a fault on the conductor under test, the detector P trips contacts R and permanently disconnects the circuit containing that conductor. Should there be a further fault on the system, the motor M will go on testing the circuits in turn until the fault has been found and disconnected, whereupon Y stops the motor.

Title: Manufacture of organic nitrates applicable in the explosives industry
IPC: C07C201/02
Filed: 1929-09-11
Abstract: Diethylene glycol is nitrated with an acid mixture comprising by weight, 3-12 per cent of water, 30-60 per cent of nitric acid and 35-60 per cent of sulphuric acid, whilst well agitating the mixture and keeping it cool.  A number of examples are given in which the proportion of nitric acid varies between 44,57 and 51,06 per cent, of sulphuric acid between 49,52 and 41,6 per cent, and of water, between 5,91 and 7,34 per cent. During the nitration, the diethylene glycol is allowed to run in a fine stream or streams into the acid mixture cooled down to 10 DEG  C., an allowance of from 5 to 10 per cent excess nitric acid over that theoretically required being made.  The diethylene glycol dinitrate is readily applied in the explosives industry, either alone, or in admixture with trinitroglycerine or ethylene glycol dinitrate.  In admixture with either of the above explosives, a solvent is obtained which dissolves nitrocellulose of 11 to 12 per cent nitrogen content in the cold.

Abstract: 631,659. Cylinders. JAMESON, J. L. Oct. 24. 1945, Nos. 28078/45 and 15522/46. [Classes 7 (ii) and 7 (vi)] In a multi-cylinder engine, combustible mixture is fed through a chamber 9 having outlet ports arranged in its outer wall in the sequence of the cylinder fixing order, and ducts 6 curved in one direction only to the inlet valves 3, the sparking plugs 5 being on the outside of these curves. Turbulence is thus avoided and the mixture richness in the cylinder increases progressively away from the piston crown. Each duct 6 may be connected to a fuel-collecting chamber which may include an extra fuel nozzle, the cylinder charge being thus enriched during the piston stroke. In a radial-cylinder engine a rotary valve may maskoff the ducts 6 in turn. Specification 591,158 is referred to in both Provisional Specifications.

With the arms 36 in the second position, Fig. 3, the roller 45 abuts a surface 46 of each member 17, 18, whereas the rollers 28, 29 enter recesses 38 of the members 15, 16 so that actuation occurs only through the second element 41, both pedals 11, 12 being coupled. This actuation operates the transmitter in the form of a piston and cylinder for pressure increase to the trailer brakes, and also operates an equal-armed lever 42, pivoted to an output rod 50 from the transmitter, to operate the mechanical linkage to the traction vehicle brakes. The piston of the transmitter has a valve therein to allow fluid leakage when the transmitter is not actuated.
