Abstract: 358,786. Weighing-apparatus fitted to conveyers. BROWN, S. C., 40, Gloucester Road, North Harrow, Middlesex. Nov. 29, 1930, No. 35943. [Class 143.] In an automatic weight-indicating and totalizing mechanism applied to a belt conveyer, the tare of the conveyer is automatically counterbalanced by passing the return stand of the conveyer over an opposing weighing section of shorter effective length than the load-weighing section but connected to the automatic weighing system by suitable multiplying levers, the means for suspending the return weighing section from the weighing system comprising narrow idlers or the like making contact only with the comparatively clean marginal edges of the conveyer clear of any adhering material likely to fall therefrom. The upper load-weighing strand 2 of the conveyer is supported by idlers 3 mounted on the weigh table 4 carried by levers 7, 8 connected to an automatic resistant lever 10. A quadrant 12 controls the weight-totalizing recorder in well-known manner. The return portion of the conveyer passes over idlers 14, 15, 16 the centre idlers 15 being supported from the lever 7 and being influenced by a portion of the conveyer of shorter length than the load-weighing section. As shown in Fig. 2, the idlers 15 engage only the edges of the conveyer and thereby avoid the dirtiest parts.

Title: Improvements relating to nuclear reactors
Inventor: BOOTH DAVID LAWRY
IPC: G21C7/26
Filed: 1960-10-27
Abstract: 914,680. Nuclear reactors. ENGLISH ELECTRIC CO. Ltd. Oct. 23, 1961 [Oct. 27, 1960], No. 36862/60. Class 39 (4). A nuclear reactor has a liquid moderator contained within a vessel provided with inlet means for at least one stream of gas which passes through at least part of the moderator, and an outlet means for exhausting the gas from the vessel. The vessel 10 is divided into a moderating region 10a, a low-pressure region 22 and a high-pressure region 10b. The blower 18 circulates gas e.g. helium from the region 22 through the conduit 16 to the dump tank 14 and region 10b or to the conduit 19. The valves 25 and 30 allow the gas to enter the perforated pipes 23 and the rising bubbles have the effect of reducing the density of the moderator in the vicinity of each gas stream and hence affects the local neutron flux. If it is desired to control the flux over only a part of the reactor then the bubbles 28 may be intercepted by a curved vane 26 which guides gas to the escape pipe 27. The flow of bubbles may be adjusted by the valves 25 and 30, and the flux is also varied from one part of the moderator to the next by varying the spacing of the holes 24. In an emergency shut-down of the reactor the pipes 23 may be used to pass some of the gas from the region 10b to the space 22 and so hasten the emptying of the moderator chamber 10a, the valve 20 being open. The moderator may be heavy or ordinary water or an organic liquid and may or may not act as a coolant.

Title: Print rate control arrangement
IPC: B41J29/20
Filed: 1975-09-09
Abstract: 1519470 Printers GENERAL ELECTRIC CO 9 Sept 1975 [17 Sept 1974] 37017/75 Heading G4H In a print rate control arrangement, a plurality of recording characters are adapted for effective serial movement across each line in succession on a record medium containing column locations and a plurality of such characters are available for substantially simultaneous recording along each line in succession in accordance with a pattern of data, there being means responsive to the number of characters to be recorded in a certain period to provide a control signal when the number reaches a certain limit which is less than the maximum number which could be printed in such period, and means responsive to the control signal to limit recording of characters. This makes it unnecessary to choose a print rate in the design to accommodate (infrequentlyoccurring) worst-case conditions, given the power and mechanical limitations. In Fig. 2, the characters for a line of print circulating in a memory 21 are compared 33 with the sum of a column count from 24 and a print belt position count (finger count) from 30, the comparator output going, via a gate 35, to hammer drivers 37 (also fed by the column counter 24), and to erase the characters giving equality in the comparison from memory 21, and to counters 38, 36. Counter 38 is unidirectional and is reset after each alignment period (of recording characters with hammers: in each such period, the drive circuits 37 control the hammers once simultaneously). If the count at 38 reaches a certain value less than the maximum number of characters which could be printed simultaneously, gate 35 is inhibited. Counter 36 is bidirectional, being counted up by the output of gate 35 and down by a desired-print-rate clock pulse train from 43 or 44. If the count becomes sufficiently high, call for the next line of characters (which normally occurs when memory 21 is empty) is inhibited at 40 (so long as the excessive count persists). A switch 70 permits the alternative of using the output of counter 36 to inhibit gate 35. Another embodiment has a unidirectional counter in place of 36, inhibiting gate 35 and being reset by clock pulses periodically.

Title: Fluid-operated braking systems
Inventor: THOMAS GORDON FREDERICK FRANK
IPC: F16D65/00
Filed: 1965-09-03
Abstract: 1,097,399. Fluid-pressure servomotor systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 28, 1966 [Sept. 3, 1965], No. 37673/65. Heading G3P. [Also in Division F2] A valve 20 for vehicle brake systems comprises a double-headed piston 37 defining chambers 32, 34, 38 and 39 connected respectively to atmosphere (via port 33), control pressure line 21, atmosphere (via port 56), and an output line 22 (via ports 68 and 69). Communication between chambers 38 and 39 through a port 46 in the piston is controlled by a valve member 44, which is integrally connected to another valve member 43 controlling a connection between chamber 39 and a supply line 14. Pressure is normally maintained in chamber 34 via its connection 21 to a control source or valve (not shown). This pressure is sufficient to maintain the piston in a raised position against spring 31 whereby valves 44 and 43 are unseated and seated respectively and output line 22 is vented to atmosphere via ports 69, 68 and 46, chambers 38 and 55, and port 56. On reduction of control line pressure, piston moves downwardly, firstly seating in valve 44 to close off the output line 22 from atmosphere vent 56 and then to open valve 43 so that pressure fluid is fed from line 14 to the output line via ports 68 and 69 until the combined pressures in chambers 34 and 39 are sufficient to cause the piston to move back and valve 43 to seat. Further decreases in the control pressure results in a corresponding increase in the output pressure. The valve is shown combined with a second valve 53 which incorporates piston 54. The piston is provided with a port 64 which permits output line 22 to be connected directly to port 56 when associated valve member 63 is unseated. Pressure supplied by a line 52 normally maintains the piston depressed and valve member 63 seated. Another valve member 64 is accordingly open and normally maintains communication between ports 68 and 69. However, on reduction of the pressure in line 52, piston 54 rises to respectively seat and unseat valves 64 and 63. In a modification, Fig. 3 (not shown), the valves 20 and 53 are replaced by a single simplified valve wherein the pressure line 52 acts to bias the doubleheaded piston 37 downwardly instead of the spring 31. Specification 1,097,400 is referred to.
