Title: Improvements in or relating to boring machines
IPC: B23B29/034
Filed: 1941-12-19
Abstract: 554,160. Boring heads or bars. AYERS, R. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 19, 1941, No. 16394. [Class 83 (iii)] Radially movable cutters of a boring head or bar are advanced to cutting position by a spring- loaded slidable member which is operated by contact with a stop member to cause retraction of the cutters and is locked in retracted position by a latch. Cutters 2, Fig. 1, are secured on holders 3 by set screws, the holders being grooved to engage a wedge section 11 of a member guided at 15, 16 and 17 in the cutter bar 1. A spring 18 urges the wedge to expand the cutters as limited by adjustable means such as screw rings 6 that engage shoulders 5 on the holders. The end 13 of the wedge contacts a stop on the machine, or work, or merely the blind end of the bore and compresses the spring 18 till the member is locked by a notch 24 and spring latch 22. The cutter holders are collapsed by spring rings 7. A knob enables the latch to be tripped manually for the resetting of the cutters. In a modification the wedge acts firstly to expand the cutters and then to retract them, thus enabling chamfering to be done. If the chamfer is to be formed at the end of the blind bore the cutters are cranked forwardly. The wedge may be of cam formation to enable a profiled bore to be produced. Instead of a wedge action the sliding member may be connected to the cutter holders by cranked levers. The latching and the cutter-adjusting means may be varied.

Abstract: <PICT:0855550/III/1> <PICT:0855550/III/2> A multi-stage flash evaporator comprises a series of heaters and a series of flash chambers located in a common vessel, each heater being provided with tubes arranged for the passage therethrough of liquid to be evaporated and for the liquid to be heated therein by liquid flashed off in the flash chambers, a single nest of tubes extending through at least two adjacent heaters, the tubes passing from one heater to the next through a partition wall common to them both.  A rectangular vessel 30 is divided by horizontal and vertical partitions 34 and 32 into two layers of evaporators in pairs.  Each evaporator comprises a flash zone 14 and a heat-transfer zone 10 (wherein the vapour from zone 14 is condensed by contact with the cold liquid in pipes 36) connected through water vapour separators 46 which remove water entrained in the flashed vapour.  The liquid to be evaporated is heated by passage through the heaters within the nest of tubes 36. To aid venting between stages the holes in the partitions through which the tubes pass may be of larger diameter than the tubes or additional venting holes may be provided.  The heater associated with the highest temperature flash chamber may be vented separately since the bulk of the non-condensible gases, e.g. CO2, will be released therein.  The apparatus may be used to purify sea water.

Abstract: 180,919. West, J., and West's Gas Improvement Co., Ltd. June 24, 1921. Fixed-chamber apparatus for granular material. -Telpher skips are charged with material such as coke from a measuring-chamber arranged beneath a bunker or like container and adapted to be filled from the bunker and emptied into the ships by the movement of the skip itself. In the. Figure the full lines show the arrangement of the parts while the measuring vessel c is discharging into the skip d, a pivoted door b covering the outlet from the bunker a. When the measuring-chamber has emptied, the skip is raised along the guides m and allows a counterweighted lever k which rests against a projection on the skip to turn and actuate a rod j and lever i so as to close the pivoted door e of the measuring chamber and lift the shoot f into the position shown bv the broken lines. The lever i is connected by a rod h to an arm g fixed to the door b of the bunker so that when the door of the measuring chamber has been closed the door of the bunker will be opened and the measuring- chamber refilled. When an empty skip descends the guides m, it rocks the lever k back into the position shown by full lines, thus closing the door b, opening the door e and lowering the shoot f, allowing the measuring-chamber to discharge.

Title: Pulse circuit with zero level compensation
Inventor: CANNADINE EDWARD MICHAEL GEORG
IPC: H03K17/795
Filed: 1962-05-08
Abstract: 1,049,777. Transistor pulse circuits. ASSOCIATED AUTOMATION Ltd. May 8, 1963 [May 8, 1962], No. 17596/62. Heading H3T. [Also in Division G4] Zero level wander in a pulse system is corrected by feeding to the output transistor of the system a zero level correcting signal derived from the input signal by way of an emitter following circuit. The circuit shown is of a photo-electric punched tape reader in which TR 3  is one of the photoelectric detectors. Signals from the detector are amplified at TR 4  and applied to a switching transistor TR 7 . The zero level of these signals should be OV but due to varying translucence of the tape and varying leakage current of the transistor they depart from this and as the signals have sloping sides the width pulse produced by the output transistor TR 7  would vary. To avoid this the zero level is detected in a negative peak detector TR 5 , C 2 , R 18  and applied to TR 7  in such a magnitude as to offset these variations. The tape reader includes a number of photo-electric detectors such as TR 3  and each is stabilized against temperature variations by respective ones of potentiometers such as R 8 -R 10 . These are fed at one end with a fixed voltage from TR 2  and at the other end by a temperature varying voltage derived via TR 1  from a thermistor TH 1  so that the slider can be set to provide the desired amount of compensation.
