Patent GB-748173-A (GB)
Abstract: 748,173. Ticket printing and issuing machines. T.I.M. (TICKET-ISSUE MACHINES), Ltd. Oct. 12, 1953 [July 14, 1952], No. 17737/52. Class 106 (3). [Also in Group XVI] A ticket or like printing and issuing machine of the kind having external means for setting type members and which machine causes a ticket or label to be printed on a web of paper and ejected, has concentrically mounted finger discs 3, 4 each operatively connected to the variable type members, each disc being held in set position until the ticket is issued. The discs 3, 4 rotate over marked plates 5 and are coaxially mounted to drive pinions 9, 13 which displace racks 11, 15, connected via yokes 28 to discs 26. These discs 26 have attached thereto rods 27 which extend into the type members. Coacting with each rack is a pawl 21 which retains racks in set position to prevent movement of the type members during printing, effected by a manual or power rotation of a shaft 2. The pawls 21 also engage another mechanism 38 which ensures that printing is prevented if either disc is held manually halfway between two operative positions: a knob 43 releases the pawls and racks. In a modification, the teeth on racks 11, 15 may be replaced by ratchet wheels associated with the pinions 9, 13.

Title: Method and device for identifying objects
IPC: G06V10/40
Filed: 1978-10-03
Abstract: In a method and a device for identifying an object with one of a plurality of reference objects, an image B of the object is scanned in an optoelectric converter V and the scanning data is stored in a store BSp. The store BSp is scanned under the control of a scan control circuit DSt and the output is fed into a parameter generator K which produces parameters capable of distinguishing between different objects. The parameters may be, for example, the total image area, the radius of the largest circle centred on the of the image centroid passing through the image, the number of intersections of the image perimeter with the scanning lines and the ratio of the part lengths of the scanning lines lying within the image to the total part length. The parameters are compared with corresponding parameters of reference objects stored in stores RSp1... RSpn by means of a comparator C1 until identity between the parameters is found. <IMAGE>

Patent GB-2036802-A (GB)
Title: Heat treatment method
IPC: C21D3/04
Filed: 1978-11-30
Abstract: In order to decarburise ferrous metal without recourse to an exothermic generator, an inert gas (typically nitrogen), water and a liquid or vaporous compound of carbon, hydrogen and oxygen (typically methanol) are admitted to a working chamber of the heat treatment furnace in which the metal is situated. The decarburisation is preferably performed at 700 to 800 DEG C. The methanol and water react to form a non-oxidising, decarburising atmosphere at the decarburising temperature. The metal may be oxidised at a temperature below 600 DEG C in another chamber of the furnace, the atmosphere from the decarburising chamber being passed into the oxidising chamber.

Patent GB-2015282-A (GB)
Title: FM receiver
IPC: H04B1/26
Filed: 1979-01-19
Abstract: An FM receiver includes a signal conversion circuit (2, 3, 4) operating to produce a first IF signal on a first intermediate frequency. This first IF signal is fed to a resonance circuit (5) turned to the Nth harmonic of this first intermediate frequency. A frequency conversion stage (10) receives the output of the resonance circuit and provides a second IF signal which is demodulated by an FM detector (9). The selection of the Nth harmonic by the resonance circuit (5) has the effect of increasing the frequency deviation of the input to the frequency converter stage so that an improved signal-to-noise ratio can be obtained. <IMAGE>

Title: Underwater paddle-type propulsion unit
IPC: B63H1/10
Filed: 1979-02-26
Abstract: A high-power, low-speed, steerable underwater propulsion unit comprises paddles (4) mounted at the rim of a driven wheel (1) supported on a chassis (10). The paddles (4) are orthogonal to a reference plane defined by the surface of the driven wheel (1), and rotate freely about axes (5) orthogonal to said reference plane. The orientation of each paddle is varied by successive small rotational movements caused by a toothed wheel which cooperates with a cogged wheel (7), the cog axes being parallel to the axes of the paddles (4). The driven wheel is driven by driving wheels (2) which engage its periphery, thereby avoiding the need to transmit high torque at low speed via a shaft. Indeed the driven wheel is centreless. <IMAGE>
Patent GB-2022373-A (GB)
Title: Interconnecting terminal devices in a digital data network
IPC: H04L12/00
Filed: 1979-04-24
Abstract: The terminal devices normally operate at different data rates or they are to be interconnected over data links in the network which normally operate at different data rates. The method involves firstly determining, by processor means at a switching point (SP) in the network, the normal data bit rate of two terminals (A, B) to be interconnected as well as the normal data bit rate of the or each data link over which the connection is to be made. In the case where there is a difference in the normal data bit rates the processor initiates a procedure to send a digital bit stream to one or both of the terminals and having the bit rate required to cause the terminals to operate, in the course of the connection, at a common data rate equal to the lowest of the normal data bit rates of said terminals and said data link. <IMAGE>

Title: Low Noise Centrifugal Blower
IPC: F04D29/42
Filed: 1979-11-06
Abstract: In a centrifugal blower having a spiral housing 11 in which the fan wheel 12 is mounted approximately concentrically of the spiral housing, the involute wall portion 19 of the blower housing 11 terminates proximate the blower outlet 15 without a curved cut-off.
