Title: Improvements in connection with centrifugal pumps and the like
IPC: F04D29/04
Filed: 1926-01-08
Abstract: 268,459. Allen, H. G., Maude, A., and Allen, Sons & Co., Ltd., W. H. Jan. 8, 1926. Leakage-preventing devices; controlling; balancing end thrust. - A centrifugal pump has an impeller-or it may be the last of a series of impellers-of the single entry type so arranged that a pressure, for example, that of discharge, is maintained in the clearance remote from the suction entry, to prevent air from entering through the adjacent gland. In the arrangement shown in Fig. 1, the condensate from surface condensers is first dealt with by a pump with a double entry impeller A. The pressure is raised slightly; air and uncondensed vapours are bye-passed back to the condenser by the pipe 1<a>. A second impeller B of the single entry type receives the condensate from the impeller A and is adapted to undertake the bulk of the work necessary to deliver against the required external head. The clearance space 5 at the back of the impeller B is in communication with the discharge side of the impeller and is isolated from the suction side, no holes being provided in the impeller plate. The adjacent packing gland 4 is thus subjected to a pressure to prevent air leakage. Adjacent the packing gland 6 at the other end of the shaft is a chamber 7 bounded on one side by a rotary piston 8 arranged as a diaphragm. A ring 9 is mounted in the casing and a fine working clearance is provided between the ring 9 and the piston disc 8. A conduit 10 connects the discharge side of the impeller B to the chamber 7 which is thus under a pressure to counter-act the end thrust of the impeller B and to prevent air from leaking through the gland. The space on the side of the disc 8 opposite to the chamber 7 is connected to the suction side of the impeller A through the clearance 11. The shaft outside the packing gland may be provided with a small thrust bearing.

Title: Improvements in and relating to bearings
IPC: B64C11/30
Filed: 1944-01-13
Abstract: 574,195. Bearings. BLACKBURN AIRCRAFT, Ltd., and MITCHELL, E. Jan. 13, 1944, No. 683. [Class 12 (i)] A bearing assembly for the hollow shaft of a hydraulically operated variable-pitch propeller comprises a plurality of flanges on the shaft which engage corresponding annular recesses on a bearing housing, which housing may be formed as an extension to the engine crankcase, with the hydraulic pressure fluid supplied to one or more of the annular recesses so that part of this fluid passes between the faces of the flanges and the recesses to lubricate the thrust and journal bearing surfaces formed thereby while the other part of such fluid passes by radial bores in the particular flanges to the hollow -shaft interior and thence to the variable pitch mechanism. Thus the hollow propeller shaft I has flanges 2-5 engaging annular recesses 31, 41 and end faces of the bearing housing 16. Pressure fluid for operating the variable pitch mechanism is supplied through passageways 18, 19 to the annular recesses 31, 41 and passes thence through radial 'bores 13, 14 in the shaft collars 3, 4 to concentric pipes 8, 9 in the hollow propeller shaft 1 ; the pressure fluid also serves for the lubrication of the combined radial and thrust bearing by passing both above and below U- section rings 17 which fit into the space between the shaft flanges and around the separating walls of the annular'recesses and act' as the bearing liners, the fluid which has acted as lubricant draining to the space 20. The propeller shaft 1 is shown coupled to the engine crank-shaft 7.

Title: Improvements in the production of photographic images
Filed: 1941-01-17
Abstract: 572,633. Intensifying photographic images. KODAK, Ltd., and BERG, W: F. Jan. 17, 1941, No. 688. [Class 98 (ii)] [Also in Group XL] A latent image, e.g. in a gelatino-silverhalide emulsion layer, is intensified by subjecting it to an overall fogging exposure with luminescent light, which may be from a selfexciting source (e.g. radioactive), or from a source excited prior to use (e.g. zinc sulphide by white light) or excited during use (e.g. by X-rays). The radiation from the source may include rays of the same wavelength as those used in forming the latent image. The sensitive layer may be shielded from any exciting radiation by a screen or filter. If phosphorescent light is used, it may in certain cases be quenched, when it has served its purpose, by means of infra-red radiation, e.g. zinc sulphide with copper as activator. Other phosphorescent substances can be made to give increased phosphorescence by raising the temperature or by irradiating them with infra-red radiation, e.g. zinc sulphide with manganese as activator, or calcium sulphide with bismuth as activator. The fogging exposure is preferably a relatively long one of low intensity, but may be made shorter and of higher intensity if the temperature is raised. A film bearing a latent image may be wound helically upon a drum which may.be rotated continuously past a luminescent source or may be placed coaxially in a cylinder coated internally with luminescent material or the film may be placed on an apron coated or impregnated with luminescent material, and if the apron is a developing apron, the coating may be protected from the processing liquids by a lacquer coating. For cut films, packs, or plates, phosphorescent material may be coated on the inside of a dark slide cover, so that it is excited by external light when the cover is withdrawn to make the latent image exposure, and effects the fogging exposure when the cover is replaced. The fogging exposure may also be made by immersing the sensitive layer in a chemi-luminescent solution, which may be a separate solution, or may be combined with a developing bath; for example, a separate chemi-luminescent solution may be prepared from a stock solution containing 3-aminophthalic-cyclic hydrazide, ammonia, methylated spirit, ammonium chloride and borax by adding hydrogen peroxide and copper sulphate to a diluted solution thereof, and a chemiluminescent developer may comprise paramethylaminophenol sulphate, potassium metabisulphite, pyrogallol, potassium bromide and sodium carbonate, the luminescence occurring on the surface where oxidation takes place.

Title: Improvements in plate lifting mechanism for rolling mills
IPC: B21B39/04
Filed: 1927-01-12
Abstract: 273,972. McCabe, T. Jan. 12, 1927. Rolling.-Plates passed through rolls x pass over strippers 48 and rockable supports J and are received and collected by a carrier A which is then moved up into proximity with the top roll and tilted when the pack can be hauled over the rolls for further passes. The carrier A is then lowered and moved out by hand-controlled mechanism to. the level of the roll pass and then moves in again to receive another pack. The carrier is raised by a hand-operated dog clutch which rotates the driving shaft E half a. revolution, thus rocking the interconnected links B and C to raise the carrier support D. The carrier is tilted by its extension engaging an adjustable stop 27 on the rocking arm F which reciprocates the carrier relative to its support D. When the levers B, C swing downwardly to lower the carrier, toggle links 1, 2 remain rigid until the end of the carrier moves out far enough to clear the supports J after which the toggle links are " broken " when the spring G moves the carrier forward to the roll pass. The supports J are raised by a cam mechanism 44 in synchronism with the downward carrier movement to assist in clearing the end of the carrier. For rolling one piece at a time the toggle links are disconnected by withdrawing the coupling pin 34. To prevent damage in case the carrier should foul the supports J when moving down, the carrier is secured to its support by a hinged plate 41 bearing an adjustable stop 42 so that it may freely tilt up. The rocking arm F reciprocates the carrier relative to its support D.

Title: Non-linear pulse code modulation with threshold selected sampling
IPC: H03M1/66
Filed: 1969-01-07
Abstract: 1,207,651. A/D converters. POST OFFICE. 7 Jan., 1969 [8 Jan., 1968], No. 963/69. Heading G4H. In an analogue to digital converter the input analogue signal is amplified by amplifiers A1-A5, (Fig. 1), the outputs from which are connected to threshold detectors 22, 24, 26, 28 which via logic circuit 30 allow the amplified signal having the highest amplitude not exceeding a predetermined maximum to be fed to a PCM encoder 52. In the embodiment described the logic circuitry 30 enables one of five field effect transistor gates 12, 14, 16, 18, 20 so that the highest amplified signal below Vmax = 10 volts is fed via subtractor 50 (which subtracts 5 volts) to a sample and hold circuit 40 connected to the PCM encoder 52. The coded output is fed to eight stages of a register 56, three further stages being connected to the outputs of logic circuitry 46 which gives a binary coded representation of the amplification factor. The states of the register 56 are serially transmitted to a register 68 (Fig. 4) at the decoder from which three bits are fed to logic circuitry 70 to enable one of the five amplifier gates 76, the remaining eight bits being decoded and the resulting signal fed by a sample and hold circuit 74, adder 78 (which adds back the subtracted five volts) and the enabled gate to one of five amplifiers A6-A10 connected'to the analogue output terminal 80. The system improves the resolution of high amplitude signals.

Title: Method and apparatus for immediate destination-call distribution on the basis of handling charges and variable bonus-, malus-factors at elevator groups
Inventor: SCHROEDER JORIS
IPC: B66B1/18
Filed: 1991-02-19
Abstract: In this method, destination calls (R(+)(-)) are immediately definitively allocated to the individual elevators (N) on the basis of higher- and lower-priority function requests to the call service and these allocations are immediately indicated at the input storeys (E1...E16). For this purpose, a weighted sum is formed from partial service costs (K1...Kn) which correspond to higher-priority function requests, this sum is modified by means of variable bonus/penalty factors (BF1...; MF1...) in the sense of lower-priority function requests with respect to service costs (KNR) and a destination call (R(+)(-)) is allocated to the elevator (N) with the lowest service costs (KNR). A destination call allocation algorithm (ZZA) according to steps 1 to 6 (SR1...SR6) with subordinate algorithms for the bonus/penalty tracking (NFA) and the cost calculation (KBA) is used for implementing this method. The tracking algorithm (NFA) is used for continuously correcting the bonus/penalty factors (BF1...; MF1...) group-by-group or elevator-by-elevator in accordance with the traffic load or cabin load. In the cost calculation algorithm (KBA), the operating costs (KNR) are calculated in accordance with a special cost formula, the corrected bonus/penalty factors (BF1...; MF1...) acting multiplicatively on a six-part partial cost sum. This allocation method improves, above all, the user-friendliness and the quantitative aspects of "waiting times" and "times to destination". It utilises capacity reserves during low traffic for additional function requests to the call service.
