Patent GB-912771-A (GB)
IPC: F16L27/08
Abstract: 912,771. Pipe connections. ARMETO ARMATUREN G.m.b.H. April 7, 1961 [April 11, 1960; Oct. 24, 1960], No. 12674/61. Class 99(1). In a rotatable hose connection a bored union nut 6, Fig. 1, receives a rotatable screw nipple 2 having a headed cylindrical shank 3 and a following threaded portion 4 to which the end of the hose 1 flexible pipe is secured, a groove 13 being provided for a packing 12 and a recess being provided in an end face of the union nut proximate a part 6a to which the nut is connected for the insertion of a further packing 9. In a further embodiment, Fig. 2, packing washers 23a, 23b, 23c are inserted in a groove formed between the end face 20 of a bush 18 and the part 21 of a bore 17 in the nut 6. The washers 23a, 23b are of a hard elastic material whereas washer 23c is of a soft elastic material and is acted upon by the internal pressure. The washer 23a has a larger internal diameter to prevent it being forced into the annular gap between the nut 6 and nipple 2. The hose is secured to the nipple by means of an externally tapered sleeve 27 which bears against the internal flange 25 of the nipple. In a modification of this embodiment the hose is secured on an externally threaded nipple by an internally tapered sleeve which bears against an external flange on the nipple.

Title: Distinguishing and decoding signals encoded in different convolutional codes
Inventor: DENT PAUL W
IPC: H04L1/00
Filed: 1992-01-20
Abstract: A decoding system discriminates between different types of communications traffic signals. Each type of traffic signal is encoded using a different error correction code. Plural, parallel decoders (40, 42) each decode a received traffic signal using a different decoding technique. Each decoding technique operates in accordance with one of the error correction codes. A quantitative measurement of the reliability of a decoded result is generated by each decoder. A comparison processor (34) accumulates the quantitative measurements made by each decoder and compares the accumulated values. That decoder having the most reliable, accumulated value is selected to decode the current traffic signals. The remaining decoders are deactivated to conserve processing time. Fields of application include cellular telephone systems. <IMAGE>

Patent GB-2261175-A (GB)
Title: Clay-based catalyst
Inventor: TAKAHAMA KOICHI
IPC: B01D53/86
Filed: 1992-11-05
Abstract: A porous clay catalyst, able to assist the oxidation of carbon monoxide, has fine metal particles deposited substantially only on surfaces of inorganic particles which are intercalated between layers of an expandable clay. The clay is expanded with a solvent, then the inorganic particles are intercalated between its layers. The inorganic particles have photo semiconducting properties, and may be, for example titania or tin oxide. A solution including ions of a metal such as Pt or Pd is mixed with the intercalated clay to form a mixed solution thereof which is irradiated by ultraviolet light. This causes the inorganic particles to produce electrons which reduce the metal ions and to deposit the metal particles substantially only on the inorganic particles. The porous clay composite is dried by supercritical drying or carbon dioxide extraction, so as not to disrupt its porous structure. An excellent oxidation/reduction catalyst is produced if the right metal is chosen.

Title: Communication system
Inventor: KIMBER PAUL KEVIN
IPC: G01S13/75
Filed: 1992-12-10
Abstract: A communication system for interrogating a pseudo-passive transponder (P.P.T.) employs an interrogator transmitting signals (22, 23) at two different frequencies simultaneously, the relative frequencies of the two signals being controlled so that the difference frequency always has one of two values ( DELTA f0,  DELTA f1), each value corresponding to a digital one or a digital zero, and is varied to carry digital data. The two signals are mixed in a diode within the P.P.T. to produce the difference signal and the frequency of the difference signal is then used to obtain the digital data. <IMAGE>

Abstract: A feedback loop in a power supply operating in a switched mode has a dual response controller which provides slow response to superimposed ripple on the power supply output by two impedance Z1, Z3 in series, and when there is transient deviation on the output, switching brings in a further impedance Z2 in parallel with one of the two impedances to reduce the overall impedance and provide a faster response for the control of the switching mode. Switching is performed by diodes D1, D2 in response to an operational amplifier A1. <IMAGE>

Title: Collision avoidance radar for land vehicles
Inventor: ANGEL RODERICK
IPC: G01S13/931
Filed: 1995-06-29
Abstract: An M-band pulse radar is integrated with appropriate signal processing logic and an audible alarm to give timely warning of obstacles ahead when driving in conditions of poor visibility. A fixed narrow beam, with 45{ slant linear polarisation, is used for simplicity and to minimise interference. A manual assessment of braking action - good or poor - has to be set into the system, but vehicle speed is monitored automatically through a parallel tapping on the speedometer drive. The radar range scale is set automatically as a function of both braking action and speed. A built-in integrity monitor presents the driver with either visible failure annunciations or deselectable confidence pips, as appropriate. The tone of the alarm depends on the selected braking action. A conformal phased array re used as the antenna.
