Title: Improvements in or relating to brake operating structures
Inventor: MASSER LLOYD DONALD
IPC: B60T13/38
Filed: 1964-04-02
Abstract: 1,063,078. Fluid-pressure brakes. NEWAY EQUIPMENT CO. April 2, 1964, No. 13625/64. Heading F2F.  In a compressed-air braking system for a vehicle, a fail-safe combined service and parking brake actuator comprises a doubleacting cylinder 30 containing a diaphragm 40 attached to flange 54 of a cup-like piston 52 and to a sleeve 46, open to atmosphere, through which passes a rod 60 carrying the piston, so that the area exposed to air in chamber 48 is greater than that exposed to air in chamber 50, a spring assembly 82, 84, 86 disposed in the chamber 48 to urge the piston-diaphragm assembly in the brake-applying direction, and ports 68, 70 each of which can be selectively connected with either a common reservoir or atmosphere, whereby the actuator is adapted to be operated for a service application by applying pressure equally to both chambers 48, 50, the force resulting from the difference in effective areas on opposite sides of the diaphragm being augmented by the spring assembly. The preferred pneumatic circuit (Figs. 5-8, not shown) consists of a compressedair reservoir (76), a valve (78) operated by the brake pedal (P) and connecting the port 68 selectively with either the reservoir or atmosphere, and a valve (80) operated by the handbrake lever (L) and connecting port 70 selectively with either the reservoir or atmosphere. In the brakes-off condition (Fig. 5), valve (78) connects chamber (48) to atmosphere and valve (80) connects chamber (50) to the reservoir, the spring assembly (S) then being compressed. When the brake pedal is depressed (Fig. 6) both chambers (48) and (50) are connected to the reservoir so that the resultant force mentioned above plus the spring force move rod 60 to the right to apply the brake via a lever (26) and cam-shaft (22) journalled in an axle bracket (24) (Figs. land 2, not shown). If, instead, the handbrake lever is operated (Fig. 7, not shown), chambers (48) and (50) are both connected to atmosphere and the brake is applied by the spring-assembly alone. This is also the case if loss of pressure in the reservoir (76) becomes excessive (Fig. 8, not shown) in the unoperated positions of the pedal and handbrake lever. It is said that by this arrangement normal use of the brakes results in a minimal amount of air being lost from the system.

Abstract: 1,099,624. Control of motors. STANLEY ELEVATOR CO. Inc. March 29, 1966, No. 13747/66. Heading H2J. [Also in Division G1] In a lift control system, ferromagnetic vanes are located in the shaftway at different levels corresponding to stations at which the car stops, two sets of vanes being provided for upward and downward travel respectively. A detector assembly attached to the car comprises transformer primary coil 57 and secondary coils 58, 59, each effective for travel in different directions. When a vane is interposed between coils 57, 58, transistor 70 is rendered non- conductive so that capacitor 96 charges sufficiently to make transistor 76 conductive. This energizes relay 86 which controls the motor driving the lift. The other secondary coil 59 controls a circuit similar to that controlled by the coil 58. The detector coils 58, 59 are located near to the amplifying transistors, so reducing the risk of picking up transient currents in the leads between them.

Abstract: 373,765. Weavers' tools; loom shuttles. LECOCQ, M. C. H. 0.,25, Rue de Chateaudun, Cambrai, Nord, France. May 9, 1931, No. 13795. Convention date, May 22, 1930. [Classes 142 (ii) and 142 (iii).] A device for facilitating the filling and threading of shuttles provided with a cover, such as are used for weaving jute, comprises a device for exerting pressure on the cover so that its catch may be released or fastened, and for inserting and withdrawing a threading hook into and from the shuttle eve. As shown, the empty shuttle A is placed in a channel-shaped rest 3. A lever 6, normally held in the position shown in full lines by a spring, is then moved by a pedal towards the cover B of the shuttle and a projection 7 exerts sufficient pressure to allow the catch D to be unlocked. At the same time, a threading hook 24 is passed through the eye C of the shuttle by mechanism operated by a lever 13 mounted on the shaft of the lever 6. The lever 6 is again raised, and a fresh spool is inserted in the shuttle. Upon operating the pedal to rotate the lever 6 again, the projection 7 again presses on the cover B and allows it to be locked by its catch, while the hook 24 is withdrawn to bring the weft end through the eye C. Mechanism is provided for moving the hook 24 into the eye and for withdrawing it on alternate movements of the lever 13. In order to tension the weft, the shuttle is provided with transverse rods E, F while the cover has stirrup-like members K, H, so that, when the cover is closed, the weft assumes a zig-zag position. A wire or inclined plate M terminating in a hook m is also arranged on the underside of the cover so that, when the weft end J is drawn, it slides down the edge P into the hook m and becomes correctly positioned for engagement by the threading hook 24.

Title: Arrangements for transmitting and receiving short electric pulses
IPC: G01S7/282
Filed: 1944-07-20
Abstract: 593,467. Radiolocation ; valve circuits. STANDARD TELEPHONES & CABLES, Ltd. July 20, 1944, No. 13949. Convention date, Jan. 23, 1943. [Class 40 (v)] In a combined pulse transmitting and receiving arrangement such as a radiolocation system, the transmitter and receiver are energized with raw alternating voltage of a period long compared with the periods during which pulses may be received, and the phase of the voltage energizing the receiver is variable with respect to that energizing the transmitter. A radiolocation system, Fig. 1, comprises an R.F. oscillator 8, modulating pulse generator 9 and aerial 10 ; a receiver 11 feeding a cathode-ray indicator 12, the sweep generator 14 for which is controlled by the pulse generator 9. A device 13 is provided to block the transmitter during the emission of pulses and a reference pulse delay device 15 provides a movable reference pulse 16 which may be adjusted to coincidence with an echo 17 on the oscillograph screen, for range determination. An A.C. source 18 provides energization directly to the transmitter elements 8 and 9 and through a phase-shifter 19 to the receiver 11, oscillograph 12 and sweep generator 14..Pulse generator 9 may be of the spark type or be a blocking oscillator, Fig. 3 (not shown), producing a pulse 20 at a definite point in the cycle of A..C. anode supply as shown in Fig. 2. The maximum operating period t<1>, during which an echo may be received corresponding with the duration of the sweep voltage 21 synchronized by the pulse 20, should occur at the peak portion of the A.C. wave as indicated at A<1>-B<1> where the variation in voltage is small. If the transmitted pulse occurs at a position such as 20a, the interval A<2>-B<2> corresponding to the sweep 21a has a large variation in voltage so that by means of phase changer 19 the A.C. wave fed to the receiving equipment is retarded by an amount # in order that the peak period A<3>-B<3> may be employed. A portion of the range A-B may be displayed on an expanded scale by the insertion of a device 22 which delays the commencement of the time base sweep which is increased in speed, the phase changer 19 being adjusted to bring the operating interval to the positive peak of the A.C. wave. The transmitted pulse may be generated at any desired point on the A.C. wave by an arrangement, Fig. 4 (not shown), which limits and differentiates the wave to produce sharp pulses, the positive pulses being selected and fed through an adjustable time delay device to control the pulse generator 9. Fig. 5 and 6 (not shown). illustrate resistance-capacity and direct coupled amplifiers which operate with A.C. anode supply, the time constants of the R-C coupling circuits being designed to filter out low frequencies such as that of the energizing source. Fig. 7 (not shown) illustrates an A.C. supply to a cathode-ray oscillograph. The sections of the voltage divider feeding the various electrodes are arranged with no byepass condensers, or with condensers associated with each section to produce similar time constants.

Title: New polymeric compositions
Inventor: MURDOCK JAMES DAVID
IPC: C08L25/14
Filed: 1960-04-22
Abstract: A thermoplastic moulding composition comprises a hard resinous polymer derived essentially from styrene and/or methyl methacrylate and a rubbery copolymer of butadiene and a monoethylenically unsaturated compound, the resin and the rubber each containing either free carboxyl groups or basic nitrogen atoms or amido nitrogen atoms so that one polymer has acidic groups and one basic group, there being from 50 to 90% of the resinous copolymer present based on the combined resinous and rubbery polymers.  The carboxyl containing polymer may contain from 2,5 to 7,5% of carboxyl groups, the basic nitrogen containing polymer 0,2 to 2% nitrogen atoms.  The butadiene copolymer may have as comonomer styrene, acrylonitrile, methacrylonitrile, methyl acrylate or ethyl acrylate or preferably 15 to 60% of methyl methacrylate and may be crosslinked to the extent of 0,1 to 5% of divinyl benzene or glycol dimethacrylate. The carboxyl polymer may be obtained by polymerizing the monomer together with an ethylenically unsaturated carboxylic acid, e.g. acrylic, methacrylic, maleic and fumaric acids.  Alternatively the carboxyl containing polymer may be polymethyl methacrylate in which some of the ester groups have been hydrolysed to carboxyl groups.  The nitrogen-containing polymer may be obtained by polymerizing the monomer and an ethylenically unsaturated basic compound containing basic nitrogen or amido nitrogen atoms, e.g. 2- or 4-vinyl pyridine, N-dimethylamino-ethyl methacrylate, acrylamide, methacrylamide, crotonamide, vinyl phthalimide, N-tert.-butyl acrylamide, di-N-ethylacrylamide and vinyl pyrrolidone.  The moulding compositions may be obtained by coagulating the polymers together or separately while in stable aqueous dispersion and thereafter masticating in a mixer.

Title: Improvements in and relating to the separation of hydrocarbons from alcohols by azeotropic distillation
IPC: C07C7/06
Filed: 1949-05-30
Abstract: Mixtures containing alcohols, other than methanol, and at least 5 per cent by weight of olefines and/or paraffins, e.g. the products of an "Oxo synthesis," are wholly or partly freed from the olefines and/or paraffins by submitting the mixture to distillation in a fractionating apparatus in the presence of methanol, whereby substantial amounts of the olefines and/or paraffins are removed as azeotropes with methanol.  In an example, methanol (1 part by weight) was added to a mixture (4 parts) containing iso-octane (13 per cent), butanols (35 per cent) and nonanol (43 per cent), obtained by hydrogenation of the product resulting from the carbonylation of a mixture of propene and di-isobutene; and the mixture thus charged with methanol was fractionated at a reflux ratio of 10 : 1 in a still having an efficiency of 10 theoretical plates.  The methanol-hydrocarbon azeotrope and excess methanol came over while the temperature at the head of the column was 56-70 DEG C, then followed the butanols at 100-120 DEG C, and finally nonanol at 185-200 DEG C.  The hydrocarbons were separated as an upper layer from the 56-70 DEG C fraction by adding water to it.  In another example, the separation of di-isobutene and iso-octane from n-propanol and nonanol, is described.
