Patent GB-2109660-A (GB)
Title: Radiographic examination apparatus
Inventor: BEETHAM STANLEY
IPC: G01N23/04
Filed: 1982-10-06
Abstract: Tube examination apparatus has a head 48, actuated by fluid pressure, for centralising a radioactive source 40. Preferably, the source 40 is shielded during transport from its storage unit to the head 48. A body 12, attached to a drive-wire 20, has hollow shield-parts 28, 30, which define a radiation window therebetween, and closure shield- parts 32, 34, which have source 40 located therebetween and which are a sliding fit in the parts 28, 30. A spring 44 biases parts 32, 34 towards a first position, relative to body 12, in which the source 40 is enclosed. When the body 12 moves along a guide 10 in the head 48, the part 32 engages an abutment surface 52 which arrests the parts 32, 34. Further movement of the body 12, to engage an abutment surface 50, causes relative movement between the parts 28, 30 and 32, 34 to a second position relative to body 12 in which the source 40 is exposed at the window. Retraction of the body 12 along the guide 10 allows the spring 44 to restore the parts 28, 30, 32, 34 to the first position. <IMAGE>

An apparatus for carrying out this recording and for reading the recorded data is disclosed. The method and apparatus are applicable to receiving image data from satellites. <IMAGE>
Patent GB-2115226-A (GB)
Title: Cam switch mechanism and control device, such as a pullkey, incorporating the same
Inventor: KNIGHT PETER DAVID
IPC: H01H3/02
Filed: 1983-02-18
Abstract: A cam switch mechanism which is particularly appropriate for use in a pullkey where one must be able to initiate two separate switching operations, i.e. lockout and signal, enables a pull on the wire (36) at either end of the unit to trigger a first response, e.g. lockout, but still permit further pulls on the wire to trigger repeated second responses, e.g. signal. First and second microswitches (one shown at 55a) are actuated via independent cam followers (one shown at 53) whose movement is controlled by linear sliding cams (27A, 27B) connected respectively to the pullwires (36) at opposite ends of the unit. Each cam (27A, 27B) comprises two parallel cam plates with the four plates interleaved so that recessed zones (as at 15) in the plates control movement of the followers. A manually controllable actuator, such as a lockout knob (60, figs. 5 to 7), may be provided to actuate the first microswitch (55a) independently of the movement of the linear cams without inhibiting subsequent sliding movement of the linear cams. The lockout knob may have pins (82) projecting into holes (17a, 17b) in the linear cams so that relative movement of the cams (27A, 27B) automatically causes mechanical latching of the lockout knob in a position in which it can only be reset manually. Electrical lockout can occur before mechanical latching.The pins (82) may be omitted. <IMAGE>

Title: Monitoring apparatus using phase locked loop
Inventor: SHERWOOD CHRISTOPHER JOHN
IPC: G01P3/48
Filed: 1984-06-15
Abstract: Monitor apparatus, for example for monitoring the speed of a conveyor belt, has a transducer for providing a train of pulses, say one each revolution of a rotary member in contact with the belt, a phase-lock loop (PLL) arrangement 10 for receiving the train and for producing an output the frequency of which is a multiple of the frequency of said train and processing means for processing said output to determine the speed. The PLL arrangement 10 has a phase comparator, a voltage-controlled oscillator (VCO) 20 and a frequency divider 22 in a feed-back loop between the output of the VCO and an input of the phase comparator. An arbitrary number of pulses from the VCO is selected to be equal to a given distance of belt travel. Consequently, the frequency divider can be adjusted according to the diameter of the rotary member. <IMAGE>

Title: Resilient laminates
Inventor: URAI MUNEHARU
IPC: A47C7/18
Filed: 1984-07-06
Abstract: A method of making a cushion body of synthetic resin material comprises laying at least a surface layer (1) and a pre-shaped filler pad (2) on each other, pressing the laminated structure at selected areas, and subjecting the selected areas of the laminated structure to ultrasonic heating and welding, thereby forming the laminated structure with a desired shape. The use of ultrasonic heating and welding permits the formation of a body of laminated synthetic resin material into a desired ornamental shape, without causing any detrimental shearing effect therein, as can occur with the known dielectric heating techniques. <IMAGE>

Patent GB-2219140-A (GB)
Title: Adaptive antenna array
Inventor: BARTON PAUL
IPC: H01Q3/26
Filed: 1984-09-29
Abstract: The circuitry for an adaptive antenna array uses a decorrelation network in cascaded stages which follows the principles of our Appln. No. 8316658, GB 2141588, with each node of the network summating two signals. One of these signals is from an antenna array for nodes of the first stage, or from a node of the previous stage depending on which stage of the network is involved, while the other signal is common to that stage (e.g. from PD1). The first such common input (PD1) comes from one antenna array and at each node one input is inverted with respect to the other to effect decorrelation. At each node one input is weighted (W11, W12, W13, etc) and the weights used are continuously updated using a processor which operates in time shared manner, and which samples the output of each node of each stage (Y1 Y2 Y3 Y4 Z1 Z2 Z3). <IMAGE>

Title: Pneumatically operated door opening mechanism
Inventor: PENNINGTON-RICHARDS CYRIL MONT
IPC: E05F15/04
Filed: 1985-08-28
Abstract: A pneumatically operated door opening mechanism comprises a single acting cylinder 15 which is mounted so that it pushes the door open when it is extended by the supply of compressed air from a servo member 8 which is inflated against a spring bias 11 to hold a volume of air at a predetermined pressure sufficient to open the door. The servo member 8 may be inflated manually when it is desired to open the door, but in an automatic mechanism it is inflated through a throttle 6 by a permanent supply 3 of compressed air and is arranged to discharge to the cylinder 15 through a normally closed valve 18 which is opened by a control lever 19 in response to operation of an actuator 33 by a person approaching a door. When the door reaches a fully opened position air escapes at a controlled rate from the cylinder 15 through a port 32 to operate a pneumatic timing mechanism 29 to cause the control lever 19 to close the valve 18 and open a cylinder vent valve 24 and allow the door to close under the action of a return spring 39. The mechanism also includes a latch 40 which engages automatically when the door is closed and is opened pneumatically when air is supplied to the cylinder 15 to open the door. <IMAGE>
