Abstract: Halogen-containing derivatives of rubber, guttapercha, balata and synthetic rubber such as methyl butadiene (excluding polyhaloprenes such as polymerized chloroprene) are milled, with or without solvents, with basic materials which retard their decomposition under heat and mechanical treatment.  Amorphous rubber hydrochloride, made by treating rubber with liquefied hydrogen chloride at low temperature, or crystalline rubber hydrochloride made by passing gaseous hydrogen chloride through a rubber solution at ordinary temperature, or mixtures of the two, or rubber chloride, or a product obtained by chlorinating a partially chlorine-saturated rubber hydrochloride may be used. The rubber hydrochloride may be bleached with hydrogen peroxide or chlorine water, or the rubber itself may be so bleached.  Rubber from centrifuged latex or vulcanized rubber may be used.  The basic materials may be oxides of calcium, strontium, barium, magnesium, aluminium, nickel, zinc, cobalt, titanium, tin, antimony or lead, or barium hydroxide, or carbonates of barium, calcium, strontium, magnesium, sodium or guanidine, or dibenzylamine, amylamine, hexa-methylene-tetramine, diphenylethylene diamine, benzylamine, diphenylamine, benzylamine, benzylamino phenol, benzalamino phenol, tetramethyl diamino diphenyl methane, diphenyl guanidine phthalate, guantol or dibenzyl aniline.  These basic materials are usually milled in with hexamethylene-tetramine.  To the composition may be added during milling (1) rubber age retarders such as amylamine, hexamethylene tetramine, phenyl-b -naphthylamine, (2) plasticizers such as dibutyl phthalate, amyl benzene, butyl stearate or oleate, a mixture of o- and p-toluene ethyl sulphonamides, stand oil, phenyl acetate, "Reogen" (sulphonated mineral oil), petrolatum, transformer oil and other mineral oils, amyl lactate, methyl hexyl ketone, paraffin, (3) fillers &c., such as silica, asbestos, clay, whiting, barytes, blanc fixe, metal powder, ground cellulose, wood fibres, (4) pigments or dyes, (5) rubber (natural or synthetic), (6) hardeners such as rosin, glycerol abietate, hexachlorethane, abietic acid.

Title: Improvements in automatic glass feeding devices
IPC: C03B7/086
Filed: 1929-03-06
Abstract: 334,560. Rankin, C. H., and Rankin Automatic Glass Feeder Co., Ltd. March 6, 1929. Delizering molten metal. - Relates to apparatus for feeding molten glass of the kind in which a hollow plunger is reciprocated vertically above an outlot in the floor of a forehearth, means being provided for applying suction and compression to the space within the plunger, which is carried by a holder to which a rotary or oscillatory movement is imparted independently of its axial movement. According to the invention the rotary plunger holder is mounted on a bracket secured to a piston rod which is movable in a cylinder to effect the axial movement of the plunger. A plunger 1 having a cavity 52 is clamped in a holder 2 by means of a plate 3 rotatable relatively to the stationary air connection 4. The holder 2 is removably clamped to a gear 5 provided with a bearing 6 in a race formed in a bracket 7 and is rotatable by means of an air driven prime mover 10 through bevel gearing 9 and a pinion 8. The bracket 7 is rigidly fixed to a rod 11 of a piston reciprocable in a fluid pressure cylinder 12, as described in Specification 290,083, whereby the hollow plunger 1 can be reciprocated simultaneously with its rotation or oscillation. The down stroke of the plunger is limited by adjustment of a rack 17 and collar 18 operated by a handwheel 13, whilst the length of its up-stroke is controlled by a handwheel 21 and screw 22 as described in the above mentioned Specification. Refractory shield blocks 23 and 24 and an annular cavity 26 through which air is circulated are provided to keep the mechanism cool as described in Specification 314,910. The operation of the feeding apparatus is synchronized by timing mechanism of the kind described in Specification 213,351 in which a cam-operated piston valve 44, Fig. 2, controls the plunger cylinder 12 by connecting ports 45, 46 of the cylinder alternately to preserve a vacuum. The pressure is supplied to the piston valve by a pipe 47 and is passed from valve port 48 to the cylinder port 45 or from valve port 49 to the cylinder port 46. Timing valves 53, 54 to control the application of suction or pressure to the glass in the cavity 52 of the plunger 1, are connected thereto by a pipe 56, and a pipe 57 is connected to a chamber, not shown, kept exhausted by a motor driven vacuum pump. In operation, when the plunger 1 is at the bottom of its stroke, as shown in Fig. 1, pressure air is being applied to the cavity 52 causing the charge 58 to be impelled through the aperture 30. The piston valve 44 is in the position to start the plunger on its up-stroke, whilst the pressure valve 54 is about to close and the vacuum valve about to open. As the plunger starts to move upwards, pressure is cut off and suction applied to the glass, which is retracted into the forehearth. The charge continues to move downwards due to its weight and the narrow neck formed is severed by shears 51 operated by a a piston valve, not shown.

Title: Improvements in or relating to devices for sensing the magnitude of deviation of operating conditions of an engine
IPC: G01P3/44
Filed: 1954-03-15
Abstract: 785,687. Electric control systems. BENDIX AVIATION CORPORATION. March 15, 1954 [April 10, 1953], No. 7479/54. Class 40 (1). A device for sensing the magnitude of deviation of an operating condition of an internal combustion engine from a reference valve comprising electrical means for producing an alternating current of frequency proportional to the value of said condition, electron tube counter means for translating the alternating current into a direct voltage, and means for comparing this with a direct reference voltage to produce an error signal. The alternating output of tacho-generator 16 driven by the turbine is fed to a pair of limiter valves 34, 42 giving an output of unidirectional constant amplitude square pulses at the frequency of the input A.C., which are fed via differentiator circuit 48, 50 to a thyratron 52 normally biased beyond cut-off. Each positive pulse triggers the thyratron to discharge capacitor 58 connected across it. The capacitor 58 recharges to voltage B+ between pulses via resistor 62, the average voltage across which is therefore proportional to the pulse frequency. The voltage across 62 is smooth by the circuit 66, 64, 68, to give a steady voltage across capacitor 70, which is applied to a differentiating network consisting of resistor 72 and a parallel capacitor 76 in series with resistor 74. The voltage across 74, which therefore has components proportional to speed and to first derivative of speed, is compared with a voltage tapped off resistor 80 set in accordance with throttle position, in the modulator 84. The modulator output is fed to a controller which includes a fuel metering valve to adjust the turbine speed either in response to a change of throttle position or to compensate for variations in turbine speed occurring independently of the throttle.

Abstract: 702,524. Counting-apparatus; zeroizing-mechanism. UNITED GAS INDUSTRIES, Ltd., and CHARLES, J. A. March 22, 1951 [March 24, 1950], No. 7488/50. Class 106 (1) In direct reading consumption counters for gas and similar meters the numeral drums are rotated forwardly by transfer pinions to indicate consumption and, for zeroizing, each numeral drum is provided with a ratchet wheel or series of ratchet teeth having a tooth for each numeral on the drum, for co-operation with a driving pawl or like element that is reciprocated by a zeroizing spindle and is rendered inoperative when the drum presents "O" at the exposure aperture of the counter by the removal of a ratchet tooth in a position related to those of said aperture and the pawl or like element, the transfer pinions being rendered ineffective during the zeroizing operation. An input spindle 9, Fig. 2, drives a spindle 11 carrying a ratchet wheel 12, Fig. 3, which through pawls 13 drives a wheel 14 which meshes with a wheel 15 on a spindle 1 on which the numeral drums 2, Fig. 1, are mounted. Fixed to the wheel 15, Fig. 3, is the driving member 16 of a Geneva mechanism the driven member 17 of which transmits step-bystep movement to the first drum 2. The succeeding drums are. driven by transfer pinions 4 mounted on spindles 3, Fig. 2, and meshing with wheels 19, Fig. 1, integral with the drums 2. A ratchet wheel 18 is integral with the wheel 15 and a ratchet wheel 20 is integral with each numeral drum 2. Each ratchet wheel 20, Figs. 1 and 2, and the ratchet wheel 18 may be stepped forward by an adjacent pawl 24 on a shaft 23 carried by arms 22 fixed to a zero setting spindle 21 manually oscillatable by means of a handle: Each spindle 3, Fig. 2, is carried by a pair of lever arms 33 rotatably mounted on a shaft 34 and urged clockwise against a rod 35 to cause the transfer pinions 4 to engage the wheels 19, Fig. 1. This resilient mounting of the pinions 4, 17 allows zeroizing to be effected. A pointer 7 is driven from the shaft 9, Fig 2, through the gears 38, 39, 41, 42. The pinions 4, 17 may be mounted on a common spindle. Specification 658,275 is referred to.

IPC: H02H3/42
Filed: 1927-03-21
Abstract: 268,758. British Thomson-Houston Co., Ltd., (Assignees of Traver, 0. C.). April 5, 1926, [Convention date]. Cut-out arrangements; induction relays.-In the protection of polyphase, feeders with the neutral point grounded through an impedance and capable of receiving reverse energy from other feeders in parallel in the event of fault, increased sensitivity of action on the occurrence of ground faults is obtained by the use of polyphase directional relays having additional windings which carry a current proportional to the vector sum of the currents in the conductors of the circuit. As shown applied to one of the feeders 3, 4, 5 which receives current from the supply bus-bars 6, 7, 8 (having a neutral earthed through the relatively high impedance 14) and supplies substation bus-bars 9, 10, 11, protection is effected by the polyphase relay 17, shown diagrammatically in Fig. 1 and as an induction type relay in Fig. 2. Each of the induction discs has an upper and lower magnet system 36, 37, the upper systems being energized by the coils 18, 19, 20 carrying a current proportional to the respective, line currents and the lower systems energized each by two windings, (1) the windings 21, 22, 23 in series, connected as shown in Fig. 1, so as to carry a current proportional to the vector sum or residual current of the lines which, in the absence of an earth fault in zero, and (2) the windings 24, 25, 26 which carry currents proportional respectively to the voltage to earth of each of the several lines, obtained from the potential transformer 30 connected across the bus-bars 9, 10, 11. The current windings 18 and 21, 19 and 22, 20 and 23 are so arranged and so connected in relation to the conductors 3, 4, 5 as to assist when a fault to ground occurs on the respective conductors and the direction of power is reversed. Normally the polyphase torque on the relay hords its contact 38 against the stop 39, but in the event of an interphase fault (unaccompanied by a ground fault) the reversal of power which may occur from the other feeders in parallel causes the operation of the relay with the result that the circuit-breaker 15 is tripped. On the movement of a fault to ground, the fault current is limited by the impedance 14 and the windings 21, 22, 23 are energized by the residual current which in conjunction with the current in the potential windings 24, 25, 26 provides the residual torque which is opposed to and greater than the polyphase torque, with the result that the relay is operated and the circuit-breaker tripped.
