Title: Improvements in or relating to the manufacture of a rim for motor-vehicle wheels
IPC: B60B25/02
Filed: 1966-04-04
Abstract: 1,129,830. Vehicle wheels. GIULIO GIANETTI SARONNO S.p.A. 4 April, 1966 [16 Dec., 1965], No. 14801/66. Heading B7C. [Also in Division B3] A wheel rim for a motor vehicle comprising a detachable side ring 3 held in place by a circlip 4 has a base portion 1 one side of which is divided into segments 11 by a plurality of axial slots 10 extending part way across the rim. The segments are permanently deformed inwards by an amount A so that when the rim is removed from the wheel they spring away from the tyre. The rim is held on the wheel by blocks acting on a portion 9 of an annular ridge 6 to clamp sloping surfaces 7, 8 against corresponding seats on the wheel spokes. The clamping action forces the segments 11 outwards into contact with the tyre.

Title: Improvements in or relating to traffic control systems
IPC: G08G1/08
Filed: 1935-05-21
Abstract: 457,121. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, RENSHAW, A. P. B., Brookwood, Dickerage Road, Kingston Hill, Surrey, and PREIST, T. P., Thotae, Bowring Park Terminus, Broadgreen Road, Roby, near Liverpool. May 21, 1935, No. 14870. [Class 118 (ii)] In a vehicle-actuated road-traffic control system, the maximum period is varied with the density of traffic flow. As shown in the Figures, right of way remains with a route until a call is received from a crossing route. Under these conditions, the cam shaft is in either position 3 or 6. If in position 3, pad DB is operated by a waiting vehicle and relay E operates and locks. Timing condensers QA, QB and QC, which time continuity, maximum period and density respectively, are connected up. Condensers QA and QC are both discharged each time a vehicle crosses the pad in the route having right of way but should a gap in the flow occur condenser QC enables relay C to energize before condenser QA is charged. Relay C de-energizes relay F which speeds up the maximum period by charging QB over MRA. If therefore traffic is continuous but spread out, relay C is repeatedly energized and each time relay F falls away to allow QB to charge at the faster rate. As a result the maximum period is considerably reduced. If right of way is removed as the result of the operation of relay B, the road relay D or E for the road losing right of way is locked up to ensure return of the right of way and to increase the amber period by cutting resistance YF or YG into the circuit. Should a vehicle cross the pad during the amber period, a slightly longer amber period is given as the resistance YG or YF remains in the timing circuit for the balance of the amber period. Specification 403,732 is referred to in the Provisional Specification.

Title: Improvements in or connected with mechanical means and instruments for measuring vertical heights of aerial targets or horizontal distances, say, for surveying purposes
IPC: G01C1/00
Filed: 1916-10-20
Abstract: 139,224. Barr & Stroud, Barr, A., and Stroud, W. Oct. 20, 1916. Range - finders. - Range-finders in which the indications are in accordance with a reciprocal scale are provided with means for measuring vertical heights or horizontal distances forming three sides of a triangle ABC, Fig. 5, one side AC is adjustable according to the reciprocal of the range and another side CB is always at right-angles to it and is geared to the range-finder so as to be at the angle of sight to the third side AB, the height being indicated upon a reciprocal scale on AB. Horizontal distances may be measured upon a part AH at rightangles to AB. In one form, Fig. 2, the working head of the range-finder drives a screw 10 through bevel-gearing, the distance CA thus representing the reciprocal of the range. An arm 12 is moved along the screw by a nut and is held at rightangles to the screw, the height being measured upon a reciprocal scale upon a member 13 which is maintained in vertical position. In a modified construction, Fig. 3, an horizontal-base rangefinder 1 is mounted in forks 2, 3 and is capable of ready detachment. The working head operates through rod and pinion, a rod 25 which carries a curved sector engaging the part 12 upon which the line CB is engraved; the part 12 thus does not partake of the angular movement of the head in its forks. This angular movement is transmitted by bevel-gears 35, 36 to the arm 13 upon which the reciprocal scale of heights is carried. The range-finder is detached from its forks by moving it axially to bring the bevel-gears out of mesh and then lifting it out; index points are marked on the gears to facilitate correct replacement. The range-finder may be of the type described in Specification 9520/88.

Abstract: 1,132,525. Edge filters for liquids. F. A. BEUTLER. 5 April, 1966 [9 April, 1965], No. 15017/66. Heading B1D. A filter with lamella stacks mounted on at least one filtrate collector, wherein the lamellae between each other and the lamella contacting the filtrate collector are orientated by interlocking elements at several places spaced in the longitudinal direction, is characterized in that at least the interlocking elements acting between the filtrate collector and lamellae adjacent to it are relatively movable in longitudinal direction in all places except one. As shown, a filtrate collector 1 of rectangular cross section has apertures 15, conical depressions 13, and V-section grooves 14. To each side is pressed (see below) an impervious but perforated plate, forming part of a stack 16. The plate has three conical projections which engage with the collector 1, and the reverse side of the plate has three conical depressions to engage in turn with a second plate, and so on. The stacks are secured by two bolts 19. Liquid flow is edgewise between the plates. Thus, where the plates are made of different material from the filtrate collector, differences in dimensions due to relative expansion or contraction are taken care of by engagement of plate projections with collector grooves. It is to ensure relatively-immovable conditions at the centre of the element that only conical depressions in collector 1 are provided there. In Fig. 3 (not shown), the provision of at least one depression and two or more grooves is repeated in the plates throughout the stack to permit greater freedom. Elements may be added, and the assembly joined to a common filtrate conduit 8.

Abstract: 1426153 Automobile air-heating and cooling system; cooling vehicle engines GENERAL MOTORS CORP 4 April 1974 [13 April 1973] 15080/74 Headings F4H F4S F4U and F4V An air-heating and air-cooling system in an automobile 10 comprises an evaporator 38 and a condenser 44 within a housing 20 which is divided by a horizontal wall 30 into an upper compartment and a lower compartment. Air is cooled by passing it over the evaporator 38 by means of a fan 36. The fan 36 draws air through an opening 34 in the automobile hood 16, and blows it over the evaporator 38 and out through an opening 42 into the passenger compartment. A compressor (not shown) passes a refrigerant between the condenser 44 and evaporator 38 through a capillary or orifice tube expander 86. The condenser 44 is cooled by air flow created by a fan 50. The fan 50 draws air through an opening 46 and over the hot condenser 44. The heated air escapes to the atmosphere through an opening 52. In the horizontal wall 30, beneath the evaporator 38, there is a trough 92. The trough collects water which has condensed on the cool evaporator. An elongated opening (94), Fig. 3 (not shown), in the bottom of the trough discharges collected water onto the condenser 44 which supplements the cooling thereof. To pass heated air into the automobile, an air damper 60 pivoted at 62 is moved so as to cover opening 52 and uncover outlet 58 to the passenger compartment. The air flow over the evaporator 38 may be regulated by a damper (not shown) which can be arranged to completely block off the flow. The condenser 44 is of the fin and tube type and has refrigerant tube passes therethrough which are connected to the evaporator. The condenser also has tube passes 66 through which hot engine coolant is passed when the system is being used as an air heater but not when used as an air cooler. During use of the system as an air-heater, the refrigerant may or may not be circulated. In one air distribution arrangement both heated and cooled air are passed to the passenger compartment in a manually or automatically controlled mixture.
