Title: Improvements in or relating to conveyors for conveying goods
Inventor: ORWIN OLAF JOHN BARCLAY
IPC: B61B10/02
Filed: 1965-10-01
Abstract: 1,132,221. Conveyers. FISHOLOW PRODUCTS Ltd. 2 Jan., 1967 [1 Oct., 1965], No. 41670/65. Heading B7L. In a conveyer (preventing release of an arrested trolley before engagement of a driving dog therewith) comprising goods trolleys 11 supported on an endless track 10 and advanced by vertically slidable (or fixed) dogs 17 carried on a chain 13 supported on a track 14, a movable cam 21 is engageable at 17b to lift the dog 17 out of engagement with the trolley 11 at a position P (Fig. 1), and a stop 28 is movable to prevent trolley advance, the cam 21 and stop 28 being carried on a spindle 23 whose rotation is controlled by a pivoted trolley release lever 31 actuated by a first trolley 11a to permit spring-effected withdrawal of the cam 21 and stop 28 and by an over-riding gravitybiased stop retainer 36 pivotable to release the stop 28 by the advance of a dog 17 for engagement with an arrested second trolley, and a pivoted control lever 30 connected by a rod 34 to the release lever 31, connected by a rod 52 to a spring loaded detent 51, 42 pivoted at 48 and engageable with the retainer 36 to displace it to release the stop 28, and inhibiting displacement of the retainer 36 except when the release lever 31 is actuated by the trolley 11a. Starting from Fig. 1, the trolley 11a has just displaced the lever 30 to 30b and hence via the rod 34, the lever 31 to 31c, and urged via the rod 52 the detent 51, 42 out of engagement with the retainer 36, and urged via the rod 25 the cam 21 and stop 28 to operative position. As the trolley 11a swings the lever 31 to 31b, the lever 30 pivots to 30c and allows the detent 51, 42 to engage the retainer so that a dog 17 engaging a follower 45 on the detent can then pivot the retainer 36 to release an abutment 40 on the shaft 23, and at the same time the rod 25 is moved to release the shaft 23. In an alternative embodiment, the detent 51, 42 is longitudinally spring urged into sliding engagement with the retainer 36, and is rotated to release the retainer by a trolley. Each dog 17 is fixed on the chain 13, and retarding and driving shoes are pivotally mounted on the trolleys as described in Specification 982,437 and are disengaged by the cam 21.

Abstract: 1,239,782. Injection moulding solid tyres. H. BUGDEN. 18 July, 1969 [2 Aug., 1968; 3 Sept., 1968], Nos. 37058/68 and 41782/68. Heading B5A. [Also in Division B7] In a method of injection moulding a solid tyre a circumferential series of inserts 33 is assembled between two mould components 10, 11 each defining the shape of at least part of one side of the tyre, and each insert has one or more projections 34 extending across it in the circumferential direction. The inserts are embedded in the tyre when it is removed from the mould and are subsequently extracted from the tyre. The tyre may be bonded, during moulding, to the rim 27 of a wheel 28, the web 29 of the wheel being held between a number of spring loaded plungers 30, 50. Pins 32, 53 projecting from the mould components in staggered array produce cavities (62) extending into the tyre from both sides to improve the resilience of the tyre. The projections 34 shown in Fig. 4 produce a zig-zag circumferential tread pattern (60), Fig. 6 (not shown) with laterally inwardly extending slots (61) produced by projections 40, 41 on the inserts 33. Metal studs 57 having enlarged beads 38 at one end are incorporated in the finished tyre by being positioned on pins 42 on the inserts. The elastomeric moulding material is placed in an annular cavity 54 and heated. An hydraulic ram 13 is actuated to close the mould and then lift it so that an annular plunger 56 forces the material in the cavity through channels 55 into the mould. The inserts 33 are made of aluminium or aluminium alloy so as to expand, when heated, more than the mould components 10, 11 (which are of high tensile steel) and leave no gaps between adjacent inserts. The inserts 33 have air bleed orifices 43.

Abstract: 1387256 Monitoring I C engine parameters ROBERT BOSCH GmbH 7 Sept 1973 [8 Sept 1972] 42202/73 Headings G1N and G1U To measure the speed of an I. C. engine a first transducer 17, Fig. 1 produces a pulse each time a selected cylinder piston is at top dead centre (TDC), to consecutively open and close a gate 11 feeding clock pulses from a generator 10 to a counter 16, via a divider 15. To measure the angle of advance a second transducer 17 senses the ignition pulses to the spark plug of the same cylinder and opens a second gate 13 to feed the clock pulses to a second counter 14. Gate 13 is closed by the next TDC pulse from the first transducer 17 and the ratio of the readings on counters 12, 14, shown at 16, is indicative of the angle of advance. To measure the angle over which the circuitbreaker contacts are closed, a third transducer 17 opens and closes gate 13 when the circuit-breaker contacts are opened and closed respectively. The ratio of the readings on counters 12, 14 is indicative of the closing angle. The counters 12, 14 may be controlled to operate as above for several engine cycles before being switched to the divider 15 whereby indicator 16 shows an average value of the measured parameter. Alternatively the outputs from divider 15 are added in a store 23, Fig. 3 for a number of engine cycles determined by a second clock pulse generator 19 and the total averaged at 22 for indication at 16.

Title: Improvements in the production of records in seismic prospecting
Inventor: DOTY WILLIAM EARL NEAL
IPC: G06G7/19
Filed: 1959-12-16
Abstract: 898,144. Geophysical prospecting. CONTINENTAL OIL CO Dec. 16, 1959 [Jan. 29, 1959], No. 42838/59. Class 40(7).  To produce a seismic record a series of seismic signals are transmitted sequentially into the earth at a plurality of transmitting stations, the signals are received at a remote receiver and recorded on a medium as a set of parallel tracks with each track corresponding to a received signal of the series, the set of tracks are scanned with a single reproducing means to produce a composite signal having an instantaneous amplitude equal to the algebraic addition of the instantaneous amplitudes of all the received signals, and the composite signal is correlated with one of those transmitted. In the embodiment a varying frequency vibrator of the kind described in Specification 768,845 is used successively at various locations 6 and fixed geophones 22, 24..30 are connected to a magnetic recorder as described in Specification 898,145. Each geophone may be replaced by a group of geophones with their outputs combined. To ensure that the transmitted signal is identical at each location a synchronizing signal is recorded, and is played back simultaneously with the recording of geophone outputs. The ensuing geophone records are played back from reproducing heads, each of which is wide enough to give algebraic addition of the signals from one geophone (or group) for all the transmissions made; thus substrata-reflected signals are emphasised relative to noise and interference. In addition the synchronizing signal is reproduced simultaneously and fed, together with the composite signals, to a multiplying and integrating circuit to provide correlation curves as described in Specification 768,845. Specification 837,917 also is referred to.

IPC: G21C7/26
Filed: 1965-10-08
Abstract: 1,108,349. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 29 June, 1966 [8 Oct., 1965; 29 Oct., 1965; 5 Nov., 1965; 17 Nov., 1965; 4 Jan., 1966; 28 Jan., 1966], Nos. 42875/65, 45907/65, 47077/65, 48932/65, 358/66 and 4014/66. Heading G6C. A reactor is controlled by causing a change between the liquid and vapour phases in a vaporizable moderator liquid present in discrete zones which are in or around the reactor core and are bounded by absorber material having neutron capturing characteristics predominantly in the thermal energy region. Thus, the ability of the absorber material to capture neutrons is affected by the variable moderating effect of the discrete zones so that, for example, a change of the moderator liquid into the vapour phase reduces neutron capture in the absorber material and causes an increase in the reactivity of the reactor core. Means for controlling selectively whether the vaporizable moderator liquid in the discrete zones is in the vapour or liquid phase may comprise either: (a) high and low pressure supplies of the moderator liquid which are selectively connected with the zones, the pressure being respectively high enough to ensure the liquid phase and low enough to ensure the vapour phase, or (b) the circulation of the moderator liquid through the zones at a selectively variable rate; the heating of the zones in the core vaporizing slow flow rates, fast flow rates remaining unvaporized. An undermoderated pressurized water reactor of the " integral " type using plutonium fuel and employing method (a) above is described with reference to drawings, the vaporizable moderator liquid in the discrete zones also being water. As shown in Fig. 4, which is a plan view of one compartment of the core, the core is formed into a plurality of compartments by means of parallel walls 40, 41 and hollow cross-walls 42, 43. Each compartment receives two fuel assemblies as disclosed in Specification 1,108,350, each assembly comprising vertical fuel plates 11, burnable poison plates 19, 20 and end plates 23, 24 of neutron absorber material, e.g. cadmium, the plates being clamped together to form a removable unit retained in the core by a spring-load fastening 59 (Figs. 7-9, not shown). The spaces in the hollow cross-walls 42, 43 form the discrete zones filled with the vaporizable moderator liquid.

Abstract: 1279655 Calculating machine RICOH KK 9 Aug 1969 [3 Sept 1968] 43092/69 Heading G4B [Also in Division B6] In a device for introducing valves into a tenkey calculating machine, items are entered into an intermediate registering device formed from a plurality of registering members 12 (Fig. 1), the registering device being shifted stepwise to bring the members 12 successively into a registering position. Each registering member 12 carries a plurality of movable member 13 each associated with a key 1, and key depression displaces the associated movable member 13 on the appropriately positioned registering member 12 from a rest to an operating position during the stepwise shifting. Each key 1 has three slots in its lower surface, one receiving a lug 3 of a corresponding control member 4; the zero-bearing key is attached to two control members 4. One end of each control member 4 is formed as a ring segment 7 (Fig. 2), those corresponding to the (1-9) keys each carrying one of a plurality of helically arranged teeth 8. A number of riders 9 engaged one by each tooth 8, are pivoted about respective fixed shafts 10 that pass through apertures 11 in the ring segments 7 and in a similar end plate 29 (Fig. 1). The end plate 29 carries a hooked retaining member 28 that coacts with an escapement 25 engaging the teeth 24 of a rack 18. A forked member 19 and grooved disc 20 rigidly connect rack 18 to a hollow shaft 15. The registering members 12, each carrying nine movable members 13, are rigidly supported on the shaft 15. Operation.-Depression of a key 1 moves the corresponding spring-urged control rod 4 and ring segment 7 (Fig. 2) to pivot the corresponding rider 9 and move it adjacent the appropriate member 13. The end face 34 of ring segment 7 bears against a rod 30 attached to end plate 29 (Fig. 1), so sliding the plate 29 until the hooked member 28 forces the escapement 25 out of engagement with the rack 18, which then moves half a step to the left (in Fig. 1) under the action of a spring 23, until engaged by the hook 28. Simultaneously, the intermediate registering device is moved to the left, sliding along a fixed shaft 16, and during the movement the appropriate movable member 13 is displaced to its operating position by the rider 9 placed in its path. On release of the key 1, the ring segment 7 and end plate 29 slide back to their original positions, the hooked member 28 releases the rack 18 which, together with the intermediate registering device, moves a further half a step to the left until re-engaged by escapement 25. In an alternative embodiment, the ring segments corresponding to the zero-bearing key also carry a tooth 8 and rider 9, and the registering members 12 carry ten movable members 13.
