Title: Drive system for multiple spindle machine tool
IPC: H02P5/50
Filed: 1981-01-29
Abstract: The drive system includes a separate servo motor (42) for powering the drum shaft (36) which serves as the basic control element for the timing and movement of tools which are operable upon the workpieces carried in the spindles. The servo motor (42) is controlled in response to the instantaneous rotational position of the drum shaft as determined by switches (38) and its speed is regulated by a tachometer (44) in a feedback loop to any chosen value. The drum shaft rotates at either high speed during tool traverse or low or feed speed during machining operations as selected by switches (38). A second tachometer (36) driven by the spindle drive system generates a signal proportional to the spindle speed and that signal co-ordinates the low feed speed of the drum shaft with the spindle speed. Conventional clutches for high-speed and reverse operation of the drum shaft are replaced by switches and potentiometers. <IMAGE>

Title: Cost display device
IPC: G01D4/00
Filed: 1981-02-20
Abstract: Apparatus for providing a consumer with a continuous readout of a cumulative total of the cost of electricity, gas or other metered commodity consumed. Includes a sensor device (2) consisting of a light emitting diode and photo-detector combination or a magnetic sensor which can be fitted into position on the transparent case of the meter to monitor the movement of a dial or wheel on the meter. The sensor device is coupled to a reader unit (1) that contains a micro computer. This times the interval between successive outputs of the sensor device and from this computes the total amount of a commodity used and using tariff parameters computes the cost. This is then displayed on a numeric display. Other facilities include entering a target consumption figure, monitoring compliance with the target, and assessing the consumption of a single appliance. A bar code reader may be used to update the tariff rates. <IMAGE>

Title: Remote position-monitoring
Inventor: WALLACE DAVID ALEXANDER RIPPON
IPC: G01D5/34
Filed: 1981-06-19
Abstract: The movements of a pointer (2) of a meter (1) past a specific point around a scale (3) of the meter are monitored by means of a pulsed beam of incident light from an LED source (4) and sensed, after reflection from the scale (3), by a phototransistor (7). As the pointer moves through the light beam, the average amplitude of pulses received by the transducer falls then rises and a trigger pulse is initiated by a level detector (11) when the average amplitude reaches a first threshold (A) during the fall. The trigger pulse is terminated when the average amplitude reaches a second threshold (B) during the subsequent rise. <IMAGE>

Title: Electronic surveillance measuring receiver
Inventor: DEWEY RICHARD JAMES
IPC: H03J5/00
Filed: 1981-08-17
Abstract: The receiver operating in the centimetric and millimetric ranges comprises first (68) and second (70) channels, each channel comprising a mixer (73 or 74), a pair of IF amplifiers (75, 77 or 76, 78), and log video detectors (83, 85, 87 or 84, 86, 88) for detecting a presence in the output of the mixer and/or amplifier(s) of the first or second channel. Pairs of local oscillators (LO1, LO3 or LO2, LO4) are connected alternately to the mixers (73, 74) of the first and second channels (68, 70), the frequencies of the pairs of local oscillators are selected such that the upper sideband of the lower local oscillator frequency overlaps the lower sideband of the upper local oscillator. Thus by monitoring the outputs of the video detectors it is possible to resolve presence in either the upper or lower sideband so that the frequency can be measured unambiguously on an IFM receiver (82) having a much narrower band than that covered by the receiver. <IMAGE>

Title: Moulding composite articles
Inventor: LOFTS P D C
IPC: B29C44/00
Filed: 1983-07-22
Abstract: The invention relates to the production of composite articles comprising an elongate solid member (17, 18) to which is bonded a shaped foamed layer. Apparatus for making such comprises a plurality of moulds (10) provided on a conveyor (20), a mould release agent is sprayed from nozzle (12) into each open mould and a foamable material is dispensed from nozzle (30) to fill the mould.

Patent GB-2123505-A (GB)
Title: Coupling
Inventor: SPRINGALL PETER DAVID
IPC: F16L33/02
Filed: 1983-06-30
Abstract: A coupling for coupling together items, such as two hoses, has a flexible band 2 and a rectangular shackle 3 folded over upon itself to define an opening (7, FIG. 3) at the fold in which a tightening means in on the form of a split pin 4 is received. Disposed intermediate the ends of the folded shackle is an abutment surface over which the flexible band passes to apply a transverse loading on tightening of the coupling. The transverse loading causes the abutment surface to be pulled upwardly of the coupling so as to pinch the flexible band wound upon the split pin thereby resisting loosening. The abutment surface may either be one end of the folded shackle or may be a bar disposed intermediate the ends of the shackle. <IMAGE>
Patent GB-2143568-A (GB)
Title: Mine-roof supports
Inventor: HARRIS ROBERT GRAHAM
IPC: E21D23/14
Filed: 1983-07-21
Abstract: In an assembly of mine-roof supports (1 to 8), when a support has completed its advancing operation it sends, to a remote processing unit, an "advance-completed" signal. That signal also identifies the specific support which has advanced. At least two supports of every predetermined number of adjacent supports each has a manual control which, when operated, sends a "manual" signal to the processing unit. The manual signal also identifies the specific support whose manual control has been operated. After a specific support has been advanced and a specific manual control has been operated, the processing unit compares the two identification signals. As a result of that comparison the processing unit will or will not send a signal to initiate advance of the next-to-advance support. <IMAGE>
Patent GB-2147166-A (GB)
Title: Apparatus and method for providing an undistorted output signal from a non-linear device
Inventor: POTTER GRAHAM
IPC: H04R3/02
Filed: 1983-09-26
Abstract: In some feedback systems, such as are used in sound cancellation systems, instability sometimes arises due to an amplifier being driven into non- linear operation. For example in the arrangement shown, stability depends on feedback via a network 14 and a subtractor 15 but instability occurs when an amplifier 13 becomes non-linear. This problem can be largely overcome by connecting a linear amplifier 18 to receive, after attenuation, the same signal as the amplifier 13. The outputs of the amplifiers after level adjustment are passed to a differential amplifier 20 which generates an error signal dependent on any non-linearity. The output of the amplifier 13 passes by way of a loudspeaker 10 and a microphone 11 before reaching an addition circuit, and tho error signal passes by way of means 22 simulating the loudspeaker, the microphone and the intervening path, before reaching the addition circuit, where non-linearity in the input signal to the subtractor 15 is corrected by addition of the error signal. <IMAGE>
