Title: Camshaft
IPC: F01L1/047
Filed: 1978-09-21
Abstract: A camshaft 1, e.g. of grey cast iron, has its cam surfaces hardened e.g. by melting along tracks 3 as by T.I.G. or electron beam heating. The edge zones are left unhardened, only the intermediate zone, e.g. two thirds the cam width, being hardened.The relative softness of the edge zones shortens the running in period in that stress peaks at the edges are obviated, whilst yet not detracting from wear resistance of the cam surface as a whole. <IMAGE>

Title: Bomb circuit disrupting device and method
IPC: F41B9/00
Filed: 1978-09-28
Abstract: A device and method for disrupting bomb circuitry. The device is a light weight tubular member having a barrel loaded with a liquid missile which is expelled by the expansion of gas from a fired cartridge. The liquid upon rupturing and entering the bomb housing, disrupts the bomb circuitry and coats the interior of the bomb housing to prevent a fire outbreak. The gas expanding with considerable force upon entering the bomb housing further disrupts the circuitry and other structures therein. The liquid attains a velocity on the order of 500 ft./sec. requiring 500 microseconds to rupture and to enter the bomb housing. The element of time to accomplish this is less than the time required by a bomb circuit to be energized to detonate a bomb. The device and method have particular application in disrupting the bomb circuitry of home-made bombs.

Patent GB-2064666-A (GB)
Title: Rotary Fluid-flow Machines
IPC: F04D29/28
Filed: 1979-05-29
Abstract: It is established practice in rotary fluid-flow machines, such as centrifugal pumps, for the rotor of the machine to have the radially innermost root portion of the blades formed as a mixed-flow section with the remaining peripheral blade portion formed as a plain radial-flow section. This provides the machine with improved efficiency but the mixed- flow portion of the blade has necessitated the root part of the blade to be of multi-curved form and this is more costly to manufacture. The present invention avoids this disadvantage by providing the machine with a radial-flow section comprising a rotor with plain blades 9, 12 and a separate rotary section having axial-flow blades 6, with a passageway fluidly connecting the separate sections. The plain radial- flow blades 9, 12 are characterised by transverse surface generator lines on the blades all lying parallel to the rotary axis of the machine: although the blades can be curved looking in end view. It is preferably arranged that the fluid issuing from the axial-flow blades 6 approximates to a free vortex to enable efficient operation of the radial section. <IMAGE>

Title: Pager Decoding System with Intelligent Synchronisation Circuit
IPC: H04L7/10
Filed: 1980-10-13
Abstract: A portable addressable radio paging unit, capable of detecting and storing up to four different alerting signals per user, is responsive to a transmission signal including a preamble (100) to enable bit- synchronisation, a recurring synchronisation code word (101), and one or more address code words (102) within a batch (103) of code words transmitted between each synchronisation code wood and the next. After achieving bit synchronisation, the receiver attempts word synchronisation using the next synchronisation code word (101). If this fails, at least one further attempt at word synchronisation is made, using subsequent word(s) (101). If failure persists, bit-synchronisation is returned to. Only one predetermined pair (i.e. one frame) of address code words in a batch can relate to the particular receiver, so after word synchronisation, battery is saved by switching off for the rest of the batch except that frame. <IMAGE>
