Title: Improvement in paving or flooring blocks and in the method of paving or flooring
IPC: E01C5/22
Filed: 1924-10-20
Abstract: 244,223. dark, E., and Gilmartin, D. T. Oct. 20, 1924. Flooring and paving slabs; compound slabs.- Paving and flooring slabs 1 of rubber or like material are provided on the undersurfaoe with a plurality of projections 3, 4, having heads or depressions 5, 6, or both heads and depressions, at their extremities for anchoring the slabs to a cementitious or like bed or base-block. Slabs may have projections varying in height, such projections being located in lines parallel with the edges of the slabs and alternating in height. The segmental projections at the edges of the slab may vary similarly in height. The projections are of circular or elongated cross section, and their junctions with the undersurfaces of the slabs may be rounded or bevelled. The number of projections spaced from the edges is greater than the number of segmental projections at the edges. The edges of the slab are bevelled as at 10 and the surfaces are provided with grooves 9. The rubber slabs may be applied to an extended concrete base, or each rubber slab may have a separate concrete baseblock, the arrangement in the latter case being either to mould the cementitious base on to the pre-moulded rubber slab, or to mould and vulcanize the rubber on to the pre-moulded base. The depressions 5, 6 are stated also to facilitate the withdrawal of the rubber slabs from their moulds. Specifications 194,618, 208,679, 214,433, and 218,919 are referred to.

Title: Improvements in or relating to vehicle parking systems
Inventor: ALIMANESTIANO MIHAI
IPC: E04H6/18
Filed: 1962-06-28
Abstract: 965,140. Mechanical garages. SPEED-PARK Inc. June 28, 1962, No. 24944/62. Heading B8E. In a mechanical garage of the kind in which vehicle-supporting tines are projected from a mobile transporter to deposit a vehicle on complementary tines in a parking bay beside the path of movement of the transporter, the bays are arranged so that each row 19 of bays immediately adjacent the passageway 13 has a neighbouring row 20 of bays on its side remote from the passageway 13. The transporter is a mobile lift tower movable on rails 15 in the passageway and the tines in the lift car 16 are in two sets 27, 27B (Fig. 4) respectively serving the two sides of the shaft. These sets are so mounted that the tines of one will pass freely over or under the cross piece 26 or 26A carrying the tines of the other. To extend either set of tines a corresponding motor 59, Fig. 11, is rotated and this rotates a crank 61 which carries upstanding pegs 64, 65 engageable in channels 55, 56 supported below the tine carriers. These do not act directly on the tines but drive them through a pulley-and-slide movement multiplying system 36, 39, 42 (Fig. 4) of known kind. The pegs 64, 65 are at opposite ends of a pivoted lever 62 which is operated so that when full extension of the tines to a bay 20 is required peg 64 is engaged in its channel and for less extension-to a bay 19-peg 65 is used. At the selected limit of extensions, the tines are lowered slightly to deposit the vehicle on the complementary tines in the appropriate bay. This lowering is effected by pairs of pivoted levers 33 and 34, Fig. 7, operated by a push rod 32 which is attached by a cable 70 to a motor driven actuator 69, Fig. 8 (not shown).

Title: Method of and apparatus for cooling liquid products particularly liquid food products
IPC: F25D3/10
Filed: 1972-05-30
Abstract: 1430385 Agitating by fluid jets; freeze crystallisation BOC INTERNATIONAL LTD 25 May 1973 [30 May 1972] 25163/72 Addition to 1371027 Headings B1C and BIG [Also in Division F4] A method of cooling or freeze concentrating a liquid food product includes the steps of introducing into a first batch 2 of the product a stream of liquified inert gas from a header 44, and using the cold effluent gas stream passing through conduit 56 to precool a second batch 4 of the product. The effluent stream from batch 4 is then returned to a liquifier 40. After the batch 2 has fallen to a predetermined low temperature and has been removed via an outlet 26, the liquid inert gas stream enters the header 46 and the effluent gas stream from batch 4 passes into the header 48. Liquid food products can thus be cooled continually. Pressure valves 78, 80, 82 are located just upstream of the liquifier 40 in order to increase the pressure above the batches 2, 4, 6 to aid the removal of the liquid product through the respective outlets. The liquified inert gas is introduced into each batch via jet or jets in a header located underneath each tank; the jets entering the tank at a low level and at an angle to the vertical so as to cause turbulence in the tank. However in another embodiment the liquified gas is introduced through one or more spray headers. An agitator operated by a motor may be disposed in each tank.

Title: Indexable sprayer with plural nozzle orifices
Inventor: PIGGOTT RICHARD GEORGE
IPC: B05B1/16
Filed: 1969-05-16
Abstract: 1,211,068. Spray producers. SPRAYING SYSTEMS CO. 16 May, 1969 [4 June, 1968], No. 25206/69. Heading B2F. A nozzle assembly comprising nozzles 29, Fig. 1, and associated passages 31 in a plate 23, is prevented from being re-indexed to the inlet conduit 20 during the flow of fluid by the interaction of a bevelled projection 41 in a sealing and latching element 34 with a matching, bevelled, recessed annular surface 42 formed in the plate 23 around each of the passages 31, the projection being held firmly in position by the pressure of fluid against the rear surface of the element. The projection is otherwise lightly held against the surface 42 by a spring 38. When the nozzle assembly is rotated about the screw 25, the rear face of plate 23 moves the projection and element rearwardly until another passage 31 is in the indexing position. This rearward movement breaks the seal 40 between the element and plate, and enables pressure fluid to escape into an annular passage 44 from which it is taken off through bleed passages 43 directed in the same direction as the nozzle orifices. The nozzle tips 29 may be mounted between the plates 23 and 24, as shown. Alternatively, different styles and patterns of orifices may be formed in a single nozzle plate (51, Figs. 4 and 5, not shown). In the construction depicted in Fig. 6, the bevelled projection 71 cooperates with a correspondingly shaped recess 72 in the rear portion of each nozzle tip.
