Abstract: 1,085,508. Control of A.G. motors. STARKSTROM - ANLAGENBAU ERFURT VEB. Feb. 25, 1966, No. 8407/66. Heading H2J. [Also in Division G3] A three-phase motor 1 drives cage 6 at a loaddependent speed which is detected by a measurement section defined by shaft limit-switches 7, a pulse counter 8 determining the time during which the cage travels through the section. The counter 8 is associated with a reference device 9 for adjusting the value of rotor resistance 4 which is not in circuit when the measurement is effected, a transmitter 10 providing feedback representing the actual value of the resistance. The motor is retarded by supplying its stator with direct-current from transmitter 11, the rotor being short-circuited. The braking current is controlled by comparing an actual deceleration signal from detector 12 with a reference signal from integrator 13. At the end of the retardation period, the motor is driven at creep speed by re-connecting its stator to the A.C. source, and its rotor to the resistor 4 which has been adjusted in accordance with the load, as described, to ensure accurate stopping ofthe cage.

Title: Article conveying, stacking and delivering apparatus
IPC: B65H43/06
Filed: 1951-04-13
Abstract: 690,522. Sheet-delivery apparatus. FAIRFIELD PAPER & CONTAINER CO. April 13, 1951 [April 14, 1950], No. 8655/51. Class 100(i) [Also in Groups XXX and XL (b)] In apparatus for conveying, stacking and delivering articles, e.g. paperboard sheets, the articles are fed by a continuously driven feed conveyer having a gate at its delivery end for temporarily blocking the flow of articles, the gate being rockable from blocking position by actuating means to deliver the articles in stack formation on a normally stationary receiving conveyer, and control means adapted to initiate movement of the receiving conveyer when a stack of predetermined height has built up on it and to stop the receiving conveyer after it has moved the stack to a selected position therealong. Preferably the control means is also adapted to control the gate actuating means to block the flow of articles during movement of the stack. As shown, paperboard sheets are conveyed between endless feeding conveyer belts 5, 6 past a normally-open rockable gate 15, Fig. 6, and between a pair of rollers 24, 25 the lower of which is driven from the feeding conveyer, and fall on to a normally stationary live rollerway consisting of rollers 32, so as to form a stack against the plate 38. When a stack of given height is formed a switch 36 is closed which controls an electric circuit such that an electromagnet valve 55, Fig. 6, is first opened, admitting fluid to a cylinder 23 whose piston moves to rock the gate 15 to vertical depending position, in which it prevents egress of sheets from between the belts 5, 6, through a rack and pinion 20, 19, and, after a short delay, motor 35 is energized and drives, through a connection 34, the rollerway. When the stack has been moved by the rollerway clear of the end of the feeding conveyer a light beam from a projection lamp 52, which is normally broken by any sheet in stacking position, is unbroken and passes up between two of the rollers 32 to a photocell 51 connected in the electric circuit. This causes motor 35 to be deenergized and valve 55 to be closed to cause the gate 15 to open to allow sheets to pass to the rollerway. While the gate is closed sheets pile up between the belts 5, 6 this being allowed for by the spindle of the forward end roller 8 of the upper belt being vertically movable in a slot 29, the spindle of the roller 24 similarly being movable in a slot 27. In its open position the gate 15 deflects the sheets from the feeding conveyer belts 5, 6 between the rollers 24, 25. A vertical adjustment of the switch 36 on the plate 38 is provided to vary the height of the stack, and to accommodate different lengths of sheets the plate 38 is supported on slides 42 along which it is adjusted by a pinion in each of two housings 41 mounted on the plates 38 engaging a rack 46 on each slide 42, the pinions being geared to further pinions mounted above the level of the rollerway on a cross shaft carried by plate 38 on which shaft an operating wheel is mounted.

Title: Improvements in or relating to spring suspension systems for motor vehicles
IPC: B60G11/16
Filed: 1940-05-15
Abstract: 539,597. Vehicle suspensions. DAIMLER CO., Ltd., and SIMPSON, C. M. May 15, 1940, No. 8679. Class 108 (ii)] A spring suspension system for motor vehicles having each wheel independently sprung provides a rate of lineal compression of the spring which increases with equal additions to the load. A helical spring 7 is held between a fixed head 8 on the chassis 5 and a base 6 pivoted to the upper arm 3 of a linkage 3, 4 connecting the hub carrier 2 to the chassis 5. An extension 10 to the base 6 is pivoted to a link 9 hinged at 11 to the chassis. As the wheel 1 rises relatively to the chassis the effective leverage distance A between spring axis and chassis pivot of arm 3 becomes less, thus effecting greater lineal compression of the spring, which is assumed to be of the type giving approximately equal compressions for equal loads. A wire 14 connected to both arm 4 and the chassis at 15 limits drop of the wheel to the position where compression of the spring 7 becomes nil, and a bump rubber 16 &c. limits its rise. In a modification the head 8 swivels, and telescoping members connect it to the base 6, the extension 10 and link 9 being omitted.

Title: Improvements in or relating to coating processes
IPC: B05D7/02
Filed: 1958-03-18
Abstract: A synthetic plastics material having cationic exchange groups on its surface and having an MBR value, as defined, within the range of 0,08 to 0,25 is coated with a proteinaceous material by applying an aqueous solution thereof having a protein content of 1 to 5%, to the surface of the plastic, and drying the coated surface.  A tanning agent, e.g. formaldehyde or basic chrome alum solution, may be incorporated in the coating solution, or applied to the coated surface.  As proteins, gelatine, casein, fish glue and or albumin are mentioned in examples, and as plastics, polyethylene, polyvinyl chloride and a polyamide.  The surface of the plastic is treated with an oxidizing agent, e.g. a solution of pyrosulphuric acid in concentrated sulphuric acid, gaseous chlorine, or a solution of chromsulphuric acid or of chromium trioxide, with or without a wetting agent, to provide cation exchange groups.  The "MBR value" is determined by treating the surface under investigation with a solution of methylene blue, washing exhaustively with water, drying, extracting with an alcoholic hydrochloric acid solution and determining the optical density of the extract, all under specified conditions.  It indicates the degree of oxidation and amount of cationic exchange groups on the surface of the plastic.  The invention may be applied to sheets and tubes and containers such as bottles and bags, to reduce their permeability to gases.

[Class 40 (iii)] Consecutive framing impulses, which are in different phase relation to the linesynchronizing impulses for intercalated scanning, are so relatively mistimed that the framing at the receiver occurs correctly. Both sets of synchronizing impulses are of the same amplitude and the framing impulses are separated by a low-pass filter comprising a resistance and a condenser with a time constant of long duration. The residual charge BC on the condenser varies with the time after a line impulse, and thus the initial voltage EF of the framing impulse FG passed by the filter and the time taken to reach the tripping voltage of the framing oscillator also vary. To overcome this, the initiation of the transmission of a framing impulse, which normally would occur at a time #T before a line impulse is delayed by a time #t, where T is the periodicity of the line impulses and t the duration of a line impulse.
