Title: Article sorting control apparatus
IPC: B07C3/14
Filed: 1958-04-09
Abstract: 887,648. Letter sorting apparatus. STANDARD TELEPHONES & CABLES Ltd. April 9, 1958 [April 9, 1957], No. 11174/58. Class 40(3). Sorting apparatus, particularly for sorting letters in accordance with the position of a stamp thereon, comprises an arrangement for conveying letters past photo-electric detecting means and means for routing letters to different containers in response to control signals derived from the detector means. Letters to be sorted arrive at A, Fig. 1, aligned along a longitudinal edge and are fed in turn past a sizing and spacing detector B which includes a number of light barriers b1-b6 each comprising a light source and a photo transistor. The output of the transistors is applied to an evaluating arrangement C (Fig. 3, not shown) which actuates a routing device W0 to prevent letters exceeding a predetermined size or too closely spaced being fed to the following stamp position detectors. The stamp is assumed to be in one of four areas, i.e. at the top right or bottom left on either side of the envelope and one stamp position detector is allocated to each area These detectors (two only, L,E and D,K, shown) are disposed between switches W0 and W1 and each, e.g. the detector allocated to search the top right hand area of one side, Fig. 2a, comprises a number of photoelectric scanning devices F1-F4 and a number of light barriers (photo transistors P1-P6 only shown). The outputs of the scanning devices F1-F4 in unit E are controlled by gate circuits H1 which are in turn controlled by the operation of the light barriers. Light barriers P1, P6 and P5 determine the height of the letter and, by gating the outputs of the scanning devices, determine which pair of scanning devices, i.e., F4, F3, F2,F3 or F2, F1, will provide an output to evaluating means. The area is scanned in two parts, when P1 is observed the gate associated with the first of the scanning devices is opened and the device scans part of the area during transit of the leading edge of the letter from P1 to P2. When P2 is observed the gate associated with the first scanning device is closed and that associated with the second device opened. The second device scans the other part of the area during transit of the leading edge of the letter from P2 to P3. When P3 is observed the second gate is closed. As stated, the output of the gate circuits is applied to evaluating means A which is of the type described in Specification 887,649. If a stamp signal is detected in the scanned area ' the validity of the signal is determined by the evaluating means and if' correct a control signal is applied via a storage circuit R to an arrangement K controlling switch W1 and via a second storage circuit S to an arrangement Y controlling switch W2 whereby the letter is Touted to one of containers M, Z, N in accordance with the stamp position.

Filed: 1942-08-14
Abstract: 568,348. Master control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 14, 1942, No. 11383. Convention date, Aug. 22, 1941. [Class 38 (iii)] A trolley-bus control has an accelerating pedal which sets up a braking circuit for coasting when returned to its " off " position ; a braking pedal for giving graduated dynamic braking; and a reverser with emergency braking positions. Acceleration. Depression of pedal closes switches A30, A47 ... A51 to give six stages of acceleration. With full depression contactors. LB and R1 first close, followed successively by R2 ... R7, whereupon R2 ... R6 open, then R8 closes followed by reclosure of R4, R5, R6 and R1 and then by field weakening contactors F1, F2. The sequence is controlled by contacts 42 of a limit relay ABR, and each contactor is maintained after actuation independently of contacts 42 by its own " make-before-break " contacts, e.g. contact arm 40 of contactor R1, which arm is spring biassed so that its left end engages a lower contact until its right end engages an upper contact. Forced. acceleration is given by depression of button 134, which energises coil 135 to close contacts 42 of relay ABR but prevents field weakening. Coasting. On first step of acceleration, coil 87 of relay BR is energised and is maintained over contacts 91 of contactor B. When the accelerating pedal is released contacts A98 close and braking contactor B lifts to give a braking loop for the motor. A field flashing relay FF lifts ; relay AR is energised over contacts 112 of contactor B and the relay ABR, now operated by its coil 25, closes contactors Fl, R1, R2 and R3 to maintain a low coasting current in the braking loop. Braking. Depression of braking pedal closes contacts B132 to energise relay BR if braking does not follow coasting; opens contacts B111 to alter the sensitivity of coil 25 of relay ABR and opens contacts B113 to de-energise relay AR. Contactor Fl drops to give full field and contactors R1 to R8 operate in a similar sequence as for accelerating. Further depression of the pedal stresses a biassing spring 129 on the relay ABR. Overload protection. Relay OLR lifts on overload and de-energises either contactor LB or B and maintains itself until pedal is released. Emergency braking. The reversing controller, Fig. 6, has a position beyond the " forward " and " reverse " positions in which a low resistance braking loop is formed via resistor 14a, wire 144 and field 11, Fig. 1a, the field being appropriately reversed.

Title: Improvements in and relating to mountings for dynamo electric machines
IPC: F16H7/14
Filed: 1937-04-21
Abstract: 492,826. Motor mountings. BRITISH THOMSON-HOUSTON CO., Ltd. April 21, 1937, No. 11402. Convention date, April 21, 1936. Addition to 442,904. [Class 35] [Also in Group XXIV] The parent Specification describes a mounting for a dynamo-electric machine by which the tension in the belt which drives the machine is automatically adjusted to vary with the load transmitted, the machine being mounted in a cradle having upturned arms pivoted to corresponding upturned arms of a base member about an axis displaced from but parallel to the axis of the rotor of the machine. According to the invention, a simplified form of mounting is provided by torsion-resisting resilient bushings seated in the upturned arms of the base member. The base member 30 has upturned arms 28, 29 in which are rotatably mounted sleeves 22, 23 having tightly fitting bushings 20, 21 to which are bonded pins 18, 19 rigidly secured to bosses 16, 17 on the hubs 12, 13 of the stationary part 10 of the motor. The sleeves are welded to rings 24, 25 provided with arms 26, 27 adapted to be adjustably secured to the arms 28, 29 by spring-pressed pins 31, 32 engaging one of a number of holes in each arm. The rotor axle 11 carries a pulley 15 driven by a belt 14. In order to provide sufficient friction to start the motor, the pivot pins 18, 19 are inserted in the bosses 16, 17 in such a manner that the arms 26, 27 are angularly displaced in the direction of the belt loop from the position in which they are to be held by the pins 31, 32. In a modification, each arm 26, 27 is secured to its upright by a screw passing through both, and adjustment of the biassing force is obtained by varying the relative position of the pins 18, 19 in their respective bosses.
