Patent GB-1184160-A (GB)
Title: Data Processing Systems
IPC: G06F13/00
Filed: 1968-12-13
Abstract: 1,184,160. Data processing systems. INTERNATIONAL BUSINESS MACHINES CORP. 13 Dec., 1968 [15 Jan., 1968], No. 59281/68. Heading G4A. In a data processing system, an error in a channel servicing one or more I/O devices causes a system interrupt and the storing of the position reached by an I/O device (in the execution of a current channel instruction) into storage locations accessible to an error recovery operation taking place in response to the interrupt. In each of a plurality of channel units linking central processors to I/O device control units, control and status signals passing between the channel unit and the current control unit are decoded (in a manner depending on the nature of the channel viz. selector or multiplex) to update three latches storing a coded indication of how far the I/O operation has progressed. On detection of a channel error, this updating is stopped, the coded indication being placed, together with other status bits, in the current channel status word which is stored as is the current programme status word which receives the addresses of the channel and I/O device. The CPU is interrupted to branch to an error recovery programme which uses the stored information to retry the I/O operation if possible, by repeating the necessary portions (sometimes including tape backup for example), as determined by the coded indication referred to, the nature of the operation, and the nature of the I/O device. Retries may be repeated up to a predetermined number.

Abstract: 1304962 Measuring radiation scattering photo-electrically EXOTECH Inc 21 Dec 1970 [31 Dec 1969] 60600/70 Heading G1A The radiation scattering coefficient of a fluid sample 24 is measured by comparing the outputs of two photo-cells 18, 22, which define together with two radiation sources 10, 12 two intersecting straight-line paths 16, 20 through the fluid. In one embodiment, the two sources, e.g. tungsten lamps, light-emitting diodes, gas discharge tubes or lasers, are pulsed alternately. With source 10 ON, the outputs from 18 and 22 respectively represent the absorption and scattering powers of the sample, and these two signals are stored, Fig. 2 (not shown). With source 12 ON, the outputs from 22 (absorption) and 18 (scattering) are again stored. The product of the two scattering signals, and the product of the two absorption signals, are then computed. The ratio of these products, which is proportional to the square of the scattering coefficient, is finally derived. The signals may be changed to logarithmic form before the computations are performed. In addition, the final circuit indication may be a time average of the scattering coefficient. The gain of each photo-cell amplifier is controlled in accordance with the source switching (30, 32) so that when an amplifier is receiving a "scattering" signal, its gain is turned up. In another embodiment, the sources are operated continuously but are modulated at different frequencies. In this case separation of the two signals from each source is achieved by filter circuitry. From such scattering measurements it is possible to determine such properties of the scattering particles as concentration and size distribution e.g. by performing measurements at a number of scattering angles. Dust and particle concentrations in gases, e.g. from smokestacks, and also turbidity in liquids, can be monitored.  The sample may be enclosed in a container. This container may house also the sources and detectors.

Patent GB-709961-A (GB)
Abstract: 709,961. Cash registers. NATIONAL REGISTRIER KASSEN AUGSBERG GES. Aug. 8, 1952 [Nov. 29, 1951], No. 27989/51. Class 106 (1) Item counting mechanism for a cash register or accounting machine comprises several item counters each having an actuator, and selecting mechanism adapted to cause a selected actuator or selected actuators to be operated, during a machine operation, by an operating mechanism, the actuators normally being unaffected by the operating mechanism. The counters 8, of which several, e.g. " 1 ", are clerks' counters and several, e.g., " V ", are transaction counters and one " TOT " counts the total number of operations, are mounted in a removable frame 1. Each counter is mounted in an individual frame 2, 3 and is operated by the usual differentially tined pawl 15 pivoted on a rod 14 carried by a yoke 11 rockable on the counter shaft 5. Reverse rotation of the counter wheels is prevented by pawls 20 and zeroizing is effected by rotation of the shaft 5 which is notched to pick up pawls 24 associated with the wheels. When a counter is to be advanced, a corresponding actuating pawl 41 is allowed to engage a recess 48 in an operating shaft 45 which is rocked counter-clockwise and then restored by positively operating cam means in each operation. The pawl 41 is thus rocked clockwise, engages a stud 47 in the yoke 11 positively to actuate the counter, and then returns, engaging the rod 14 positively to restore the yoke It. Coupled by a spring 43 to each actuating pawl 41 is a selecting pawl 38 pivoted on the same shaft 4, both pawls being urged clockwise by a spring 39. Normally, when the shaft 45 is rocked the pawls 38, 41 are only rocked slightly by the spring 39, a tail of the pawl 38 then engaging the full surface of a tube 30 (in the case of the transaction counters). The actuating pawl will not then be rocked further to operate the counter. However, the tube 30 has helically spaced apertures 31 and is pinned to a shaft 27 carrying a gear 28 by which it is positioned according to the setting of the transaction, differential mechanism. Thus, if a transaction key corresponding with the counter being considered has been depressed, the pawl 38 will be able to enter an aperture 31 and the actuating pawl 41 will be fully operated by the shaft 45 and will in turn operate the counter. The pawls 38 associated with the clerks' counters co-operate with a similar tube 34 fast with a gear 35 positioned by the clerks' keys differential mechanism. The pawl 38 of the total counter is always free to operate.

Title: Semi-conductor lasers
IPC: H01S5/14
Filed: 1978-06-22
Abstract: A double heterostructure semi-conductor laser has the configuration of its optical cavity arranged to impose a constraint on the lasing filament as the spatial distribution of the lasing filament changes from that occuring at the threshold level so that the optical flux emitted by the laser has self-saturating properties. This protects the laser from catastrophic facet erosion and enables a simpler control circuit to be used to drive this laser when it is used as a light source for an optical communications system.

Title: Profile control device
IPC: E21D9/00
Filed: 1979-03-23
Abstract: This invention relates to a device used to control the movement of the pivotable rotary cutting head- carrying boom of a tunnelling machine. The device includes at least one boom mountable resiliently deformable member, e.g. a fluid filled tube 18 fitted around the boom 7. When the boom 7 is moved so that tents) is presses against a tunnel profile- determining guide 17 associated with the machine, the pressure on the member increases to produce from the member an output indicative of the pressure to a control system for controlling the pivotal movement of the boom to appropriately cause movement of the boom to restrict the path of the cutting head to form a tunnel of the desired profile. According to the preferred embodiment the increase in pressure causes a piston 37 to move in a cylinder 38 until a dog 41 on the piston rod 40 actuates a switch 42 which cuts out the drive to the boom 7. The boom 7 is therefore stopped before it impacts against the tunnel or shield 17. <IMAGE>
Patent GB-2025703-A (GB)
Title: Vibration motor
IPC: H01L41/09
Filed: 1979-05-14
Abstract: A vibration motor comprises a concentrator of torsional vibrations 13 whose end face is in close contact with a rotor 1. The concentrator is driven by a piezoelectric cell 14 energised by an oscillator 22. A feedback piezoelectric cell 15 is disposed beneath the cell 14. A magnetic field source (as shown a magnet 6), holds the rotor (1) firmly against the end face of the concentrator 13, and forms a magnetic circuit with a disc 2 on the rotor and a stationary part 10. These have complementary teeth 3, 11, so that on rotation the attractive force varies periodically dependent on rotary speed. This rotary speed pick up modulates the output of the feedback cell 15 with a low frequency signal dependent on speed. The high and low frequency components of this output are separated at 24. The i.f. signal is fed to a unit 25 which provides a d.c. signal indicative of speed, this being used to regulate the output of oscillator 22. Modifications are disclosed whereby the magnet has a different position or is replaced by a coil. <IMAGE>

Patent GB-2057773-A (GB)
Title: Aerial systems
IPC: H01Q1/48
Filed: 1979-09-06
Abstract: In order to modify or improve the performance of a radio transmitting aerial it is often desirable that the ground around the aerial act as a reflector of the emitted radiation. At present a constant high reflectivity of the ground around an aerial is commonly attained by laying in the ground a grid-like network of wires at a spacing considerably less than the wavelength the aerial is working at, but this is an expensive operation, and a cheap alternative is required. The invention provides a method for improving the reflector effect of the area of ground (bounded by line 12) upon which the aerial (10/11) stands, in which method the ground is permeated with an aqueous, preferably saturated, solution of calcium sulphate (as 13) so as to increase its conductivity and thereby improve its reflectivity. <IMAGE>
