Patent GB-2084253-A (GB)
Title: Improvements in or relating to apparatus for generating reciprocatory motion
IPC: F15B15/08
Filed: 1981-08-27
Abstract: Apparatus for generating linear motion comprises a body (1) on one end of which is mounted a cylinder (3A). A piston in the cylinder is joined to an actuating beam (2) extending into the body. The actuating beam has moving surfaces that cooperate with fixed surfaces in the body to define a linear bearing. Fluid under pressure is introduced through a duct (14A) in the body to a port (12A) in the fixed surface of the linear bearing. It enters the space in the cylinder above the piston via a port in a moving surface of the actuating beam which leads to a duct in the actuating beam that opens through the crown of the piston. A resilient sealing member (15A) between the fixed and moving surface of the linear bearing maintains fluid- tight communication between the fixed and movable part over their range of relative movement. The actuating beam may carry a rack that drives a pinion through ninety degrees as the piston travels, and two opposed cylinders may be provided to give a reciprocatory movement, or a spring return may be provided. <IMAGE>

Title: Method of elevator group control
IPC: B66B1/20
Filed: 1981-09-11
Abstract: In a method of elevator group control, which selects a service elevator from among a plurality of elevators with respect to a new call made at one of a plurality of floors on the basis of a weighting equation, with respect to each elevator, estimated waiting periods at floors at which new calls are made, at floors at which calls have already been made and at floors to which the elevator is destined by calls made thereinside are calculated. The estimated waiting periods thus calculated for each elevator are converted into corresponding weighted values. The conversion to the weighted values is effected according to a function having a minimum value corresponding to a reference estimated waiting period. From the weighted values the average weighted value is calculated for each elevator. The elevator for which the average weighted value is least among the average weighted values calculated for the individual elevators is selected as a responding elevator. <IMAGE>

Patent GB-2098029-A (GB)
Title: Channel protection switching arrangement
IPC: H04B1/74
Filed: 1982-04-27
Abstract: An errorless channel protection switching arrangement utilizes a variable delay (29) in the spare channel (21-24, 26-29, 31-33) adjusted to provide data signal alignment with an impaired regular channel before substituting the spare channel for the regular channel. This switching arrangement is able to provide bit error free channel substitution between the spare and any regular channel in a digital radio system by virtue of the data signal alignment capability. Data signal alignment is provided by first aligning clocking signals in fine incremental steps with each clocking signal derived from one of the two channels undergoing the substitution. Data signal alignment is then provided by shifting the spare channel in full bit positions until data alignment is indicated by a detector (119). Data signal alignment is also utilized to restore service to a regular channel so the spare channel may be removed from service. <IMAGE>

IPC: G01J5/52
Filed: 1982-12-03
Abstract: Apparatus for measuring the temperatures of an IR radiation emissive object (12) comprises a housing (8) having an aperture at which is located a body (4) of IR- transmissive material. The body (4) is thermally controlled by a Peltier-effect device (6) and has a first portion (4A) which acts as a window for transmitting radiation from the object (12) to a detector (1) via an optical arrangement (2, 3). A second portion (4B) of body (4) has a covering (5) which prevents transmission of radiation from the object (12). Optical arrangement (2, 3) is arranged to switch the detector (1) alternately to receive radiation from portions (4A) and (4B) of body (4) and the detector output drives a closed loop temperature controller (10) coupled to device (6) in order to provide a zero differential detector output signal, whereupon the temperature of the body (4) is an accurate measure of the temperature of the object (12). The temperature of body (4) is measured by any suitable sensor. <IMAGE>

Title: Applying powder to a web before and between printing units
Inventor: FISCHER HERMANN
IPC: B41F23/06
Filed: 1983-08-02
Abstract: In order to overcome occurrences of double-printing in the second and subsequent printing units in web-fed rotary presses of the serially constructed type, particularly at high speeds, devices (21,22) are used for applying powder (23) across the web (4) on its side(s) to be printed, in front of the first printing unit or a subsequent unit other than the last in the series. Powdering the web (4) causes it to be released very quickly from the blankets (17,18) after leaving the impression line between the blanket cylinders (7,8). The disturbance in the web occurring in known arrangements owing to "sticking" of the web to the blanket because of the viscosity of the ink film (19,20), which leads to double printing due to premature striking of the cylinder of the subsequent printing unit, is thereby effectively eliminated. The amount of powder adhering to the web may be influenced by ionisation devices. <IMAGE>

Title: Recoilless weapons
Inventor: JOHANSSON BORJE
IPC: F41A1/10
Filed: 1983-10-19
Abstract: A reaction mass (7) for recoilless weapons comprises a front particle reaction mass (12) and a rear liquid reaction mass (11). The particle (e.g. steel grit) reaction mass (12) retards the extinction of the powder gasses by the liquid (e.g. alkaline solution) (11) in such a way as to achieve more effective extinction from the internal ballistic point of view, and avoiding forward projection of the liquid into the loading chamber which can occur when the powder gases are extinguished too early, thereby imparing the function of the weapon. Pressure distributing layers (16, 17) of cellular plastic are disposed between a curved steel wall (15) sealing an outer capsule (14) and a reaction mass container (13), and between the two reaction mass containers (10, 13), which containers are housed within the capsule (14) and contain the particle and liquid reaction masses (11, 12) respectively. <IMAGE>

Title: Under-reaming of small diameter boreholes
Inventor: DURKAN MICHAEL THOMAS
IPC: E21B10/32
Filed: 1985-03-22
Abstract: An under-reaming machine for forming one or more enlargements below the surface of a borehole preformed in the ground comprises one or more pairs 3, 4, 5 of cutting blades 1, 2. The cutting blades 1, 2 are hinged together at one end, and respectively to an inner shaft 7 and an outer shaft 8 at their other ends. Relative axial movement of the shafts 7, 8 thus causes controlled opening and closing of the cutting blades 1, 2. In use the cutting blades are lowered into a borehole and further screw threaded sections 7A, 7B etc; 8A, 8B etc are added to the shafts so that they remain extending above the surface. The shafts are locked together by a dog clutch so that each shaft is driven to rotate directly from a driving head 6 in which they are mounted. The cutting blades are progressively opened by relative axial movement of the shafts, effected by a hydraulic ram at the surface. As the blades open and rotate, one or more enlargements are formed below the surface in the borehole, and spoil is carried away continuously by a flushing medium supplied through a passage in the inner shaft 7. The extent to which the cutting blades have opened and hence the size of the enlargements is indicated at the surface by the movement of the shaft 7 relative to the driving head 6, and this is measured by means of a scale. <IMAGE>
