Title: Arming system for a fuze
Inventor: TYERS ANTHONY
IPC: F42C15/295
Filed: 1980-10-09
Abstract: In an arming system for a fuze, e.g. a bomb fuze, a turbine 1 is drivingly engaged to a spring 5 via a primary differential 10 and a secondary differential 17 to wind it up, for a time set by a timing mechanism 6 which also appropriately locks the differentials via locks 18, 18' and 19 to produce the driving engagement. Once the set time is over, the timing mechanism releases lock 19, so that either a fast or slow arming can take place to move a detonator carrier 11 to complete an explosive train, with a selectable delay. In the slow arming mode lock 18 is released but lock 18' is engaged so that turbine 1 is disengaged from the spring 5 which unwinds, and the detonator carrier is moved, at a rate determined by an escapement 9. In the fast arming mode lock 18 is engaged and lock 18' released by a solenoid 27 so the turbine drives the differential 10 in addition to the spring 5, thus increasing the rate of arming. The solenoid is controlled by a counter 15 which causes it to select the fast arming mode until a selectable number of pulses produced by a pulse generator 16 have been counted. In a modification of the system, (Fig. 6 not shown) the turbine directly winds a spring and all the energy required for both slow and fast arming is derived only from the spring. <IMAGE>

Title: Frequency synthesiser
IPC: H03L7/197
Filed: 1981-06-16
Abstract: The operation of a multi-stage frequency synthesiser is simulated one stage at a time by simulating each stage sequentially for a limited period. An offset frequency for each stage and related to an interim frequency produced in the preceding stage, or to a reference frequency is stored via a delay line (35) for a suitable period. A modulo-N divider (36) is stepped to each digit in turn of a required frequency (or each of an appropriate sequence of ratios) starting with the least significant digit. When the complete frequency has been achieved by the first loop (29-39) a second voltage controlled oscillator (V.C.O.2) is switched in to store the complete frequency, after which the frequency is resynthesised using the first voltage controlled oscillator V.C.O.1). The delayed offset frequency is obtained by means of the fixed ratio divider (34) and the delay line (35). A further indirect synthesis arrangement is described with respect to Figures 7 and 8, and a direct synthesis arrangement is described with respect to Figures 9 and 10. <IMAGE>

Abstract: A circuit for monitoring the rate of rotation of a high speed centrifuge 1 comprises an optical speed- scanning arrangement 5, 6 and a tachogenerator 14, the output of the optical arrangement being compared with a reference maximum speed setting, and the output of the tachogenerator being used to check that the optical arrangement is functioning correctly. The output of the optical arrangement 5, 6 is compared at 10 with a reference voltage 20 representative of a maximum desired speed n3. When this speed has been reached, comparator 10 supplies an output to logic circuit 17 which causes the power supply to the centrifuge motor 3 to be disconnected. The outputs of the optical arrangement 5, 6 is also supplied, together with the output of tachogenerator 14 to a second logic circuit 16. The circuit 16 causes circuit 17 to disconnect motor 3 if the tachogenerator output indicates that a speed n2 has been reached without optical arrangement 5, 6 indicating that a speed n1 has been reached, where n1<n2<n3. <IMAGE>

Title: Apparatus for imaging and thermally treating tissue using ultrasound
Inventor: VILKOMERSON DAVID H R
IPC: A61B17/28
Filed: 1983-01-06
Abstract: A selected portion of tissue to be treated is imaged using a pulse-echo ultrasound imaging system. This system comprises an ultrasound transducer which is driven during imaging at physioligically tolerable power levels. Once the imaging system is positioned to image the tissue portion to be treated, the power at which the transducer is driven is increased to a physioligically intolerable level which is sufficient to thermally treat that tissue portion. Following scarring, the tissue portion is again imaged to determine the effectiveness of the treatment. The preferred embodiment apparatus comprises a transducer-lens system for focusing ultrasound onto a preselected focal area, an imaging means for displaying images constructed from the echoes of said ultrasound, and a pulser means selectively operable at physioligically tolerable or intolerable power levels to selectively image or to cause thermal treatment of tissue in the focal area. <IMAGE>

Title: Mechanised welding with weaving motion
Inventor: BAXTER CHRISTOPHER FRANCIS GEO
IPC: B23K9/12
Filed: 1983-11-23
Abstract: In a method and apparatus for mechanised welding of a joint in a work piece a welding electrode (7) is melted at a rate V, the joint is prepared at an angle  theta  from the horizontal, the work piece is moved past the welding electrode (7) at a speed T and the welding electrode (7) is weaved across the joint at a frequency F and width W. With V and  theta  constant the variables F and T are synchronously changed with W such that: T = (W + w)/v and F = xT + y where w, v, x and y are predetermined constants. If  theta  is allowed to vary while V is constant then w, v, x and y are all found to be directly proportional to  theta . Similarly if  theta  is held constant while V is allowed to vary the welding equations can be modified by replacing w, v, x and y which are all found to be proportional to V.

Title: Optical communications
Inventor: HUNTER IAN
IPC: H04B10/2587
Filed: 1984-10-18
Abstract: For military and civil secure communications each remote station 12-21 does not itself generate a light beam but instead merely reflects, suitably modified, a light beam transmitted to it by the home station 1-8.

Title: Price ticket displays
Inventor: KENNEY GEORGE HERBERT WOODWARD
IPC: G09F3/20
Filed: 1985-02-20
Abstract: A price ticket display comprises a holder 1 of convex or concave shape with two opposed channels 2,3 and a rigid but flexible panel which may be slid or sprung into the channels so as to lie closely adjacent a back support surface 1. The display panel comprises a sleeve formed of a back sheet 4 of preferably an opaque, e.g. black, plastics material which is rigid or semi-rigid and to which a transparent front sheet 5 is connected by means of an ultrasonic weld along the top edge 6. This sleeve is adapted to receive a panel 7 as shown in Fig. 3 comprising a sheet of rigid, semi- rigid or flacid material which has printed thereon or is capable of carrying components which may indicate the type of produce and price. The panel 7 is inserted between the back and front sheets 4,5 of the sleeve which is then flexed to engage the channels of the ticket holder 1. The effect of this flexion is to grip the insert panel firmly in the sleeve so that it can be made undersized, an example being to locate it centrally allowing the colour of the backing sheet to create the effect of a peripheral frame. <IMAGE>
