Title: Improvements relating to collapsible push carts
IPC: B62B7/06
Filed: 1946-12-04
Abstract: 619,348. Road vehicles. LINTON, .E. G. Dec. 4, 1946, No. 35851. Convention date, Dec. 24, 1945. [Class 108 (i)] A push-cart collapsable to a case arrangement has retractible wheels operated by the propelling handle, The U-shaped handle 32 has side limbs 31 which telescope into tubes 28 pivoted at 30 to the inner plates 18 of the side walls 12. Pin 56, secured to the lower end of each tube 28, projects through the slot 58 in the inner plate 18 and is connected by a link 65 to the three-armed lever 67 pivotally mounted on supports 68. Thus, pivotal movement of the handle 32 about the pivots 30 causes partial rotation of the three-armed lever 67 which retracts wheel 59 via link 72, bell-crank 74 and link 77 and wheel 60 via link 70. Spring-controlled flaps 15 close automatically when the wheels are fully retracted. The chair back 36 is normally held in alignment with the handle 32 by means of a spring catch which may be released to allow the back 36 to assume a position suitable for a recumbent attitude of the occupant. The seat 22 is supported by pins 24 engaging slots 25 in the fixed plates 26 and may be moved to an upper position wherein it is supported by engagement of the pins 24 with the slot extensions 27. Other wheel-operating mechanisms are also described.

Abstract: 638,359. Junction-boxes. LOVELL, A. J. Dec. 4, 1946, Nos. 35853/46 and 19089/47. [Class 38 (i)] A junction-box particularly for positioning inside a lighting pole comprises a sealing chamber 10 for incoming cables A, B, C, into which fits a terminal block 11 of moulded insulating material. The upper portion of the block is formed with two steps 21, 22 or more, according to the number of cores in the incoming cables, each step having a row of bores 24, 25 respectively corresponding to the number of incoming cables. One or both sides of the block is or are extended laterally at 26 and provided with bores 27, 28. The cores of the cables A, B, C and of outgoing cables D, E are inserted in the bores 24, 25 and 27, 28 respectively. For non-selective interconnection of the cables the upper ends of the cores are fitted with terminals 32 which are connected together by bus-bars 34, 34 (a) and for selective interconnection, the non-selected cores are fitted with insulating thimbles. In a modification, Figs. 4, 5 (not shown), connection between the bus-bars and the terminals on the cores of the outgoing cables is effected through cartridge fuses. Instead of the cable cores being passed through the bores in the block 11, metal terminal rods may be moulded therein, the cables being connected to the lower ends thereof. In order to prevent access of moisture to the connections the upper part of the block is enclosed in a cowl 12 of resilient material as described in Specification 638,409.

A process for the production of a high solids aqueous polymer emulsion comprises preparing an aqueous pre-emulsion of at least one polymerizable monomer containing at least one ethylenically unsaturated group which is capable of forming, in the presence of a suthcient amount of at least one surfactant, a stable preemulsion and subsequently a stable latex polymer, said pre-emulsion containing water in an amount ranging from 6 to 25 weight per cent based on the total monomer present in said preemulsion, adding said pre-emulsion incrementally or continuously to a reaction medium comprising a portion of water, not required for forming said pre-emulsion but necessary to obtain the solids content desired in the finished product, maintaining said reaction medium at a temperature to initiate and continue the polymerization reaction and controlling the rate of said addition of said pre-emulsion to provide substantially complete conversion of said monomer or monomers to latex polymer, said polymerization being conducted in the presence of a sufficient amount of a free radical polymerization catalyst to provide substantially complete monomer conversion to produce a latex having total solids in the range from 50 to 75 weight per cent. Any anionic and/or non- ionic surfactant can be used in preparing the monomer pre-emulsion, which may also include a protective colloid. Polymerization is preferably effected with an initiator such as hydrogenperoxide, alkali metal and ammonium persulphates, perphosphates, perchlorates and perborates, azobisisobutyronitrile, t - butyl hydroperoxide and redox systems. In examples the following are polymerized (a) ethyl acrylate and methyl methacrylate, (b) vinyl acetate, ethyl acrylate and dioctyl maleate, (c) vinyl acetate, and (d) vinyl acetate and dioctyl maleate. The high solids polymer emulsions prepared in the above manner are useful in paint compositions, in the continuous production of films, in the production of elastomers, cross-linkable sealants and adhesives, in making foams, and in emulsion spinning processes.

Abstract: 793,178. Photographic cameras. DECKEL, H., and DECKEL, F. W. Dec. 28, 1955 [Jan. 5, 1955], No. 37118/55. Class 98(1) In a photographic camera, one depth-of focus pointer is driven through a link pivotally connected to a ring driven by the diaphragm control mechanism and having a control pin guided in a stationary curved guideway and the other pointer is driven from the first by gearing which' moves it equally in the opposite direction. Preferably, link 40 is carried on pivot pin 36 on diaphragm follower ring 30 and control pin 46 rides in slot 48 of stationary ring 50. Link 40 is connected to ring 16 by pin 42 engaging radial slot 44. Meshing pinions 22 and 24, mounted on fixed ring 20, mesh with rings 16 and 18 respectively so that pointer 12 can be moved equally and oppositely to pointer 10. In a lens mount (Fig. 2), having the front optical element movable axially, on rotating ring 90, for focusing, a range scale is carried on the periphery 92 of ring 90 and co-operates. with the pointers 10, 12 and a reference mark (not shown), on the external part of fixed ring 20. Space 64 is provided to accommodate the shutter mechanism and the shutter speeds are set by ring 72 carrying a shutter speed scale co-operating with this reference mark. A diaphragm operating ring 66 engages lug 32 driving ring 30 and is connected to a diaphragm setting ring 74. This ring is movable axially against spring pressure of ring 66 to free it from toothed engagement with ring 72 so that the diaphragm aperture can be adjusted without simultaneously adjusting the shutter speed. When rings 72 and 74 are rotated together the shutter speed and diaphragm aperture undergo compensating variations so that the light quarter remains constant. A light value scale on ring 74 and a reference mark on ring 72 may be provided instead of, or in addition to, a diaphragm aperture scale 34 on ring 74 which co-operates with the reference mark on fixed ring 20. A corrugated annular spring 98 holds the arrangement shown in Fig. 1 in place in the lens mount. Specification 744,962 is referred to.

[Class 106 (iv).] A device for registering the time of closing of a receptacle comprises a locking means adapted to lock the receptacle and a pair of stop watches one of which is stopped and the other started on operation of the locking means. As shown in Figs. 1, 2, and 3, a receptacle 4 is attached to a frame 5 on which is pivoted a recessed frame 6 carrying a bifurcated locking bolt 10, 11, with slots 12, 13 engaging the stop elements 14, 15 of a pair of reversely disposed watches 8, 9. The frame 6 is closed by a hinged cover 7 carrying a spring catch 25 for co-operation with the bolt and a lock 27 for locking the cover in closed position. The limbs of the bolt 10, 11 are connected by a bridge-piece 20 having a pin 21 projecting through a slot in the cover 7 and a spring 28 tends to hold the bolt in retracted position. When the bolt is retracted and the receptacle opened the watch 8 is set going to indicate the time and the watch 9 is stopped and then set to the time it is desired to close the receptacle. In the retracted position of the bolt the spring catch 25 rests on top of the limb 10. To close the receptacle the pin 21 is moved to the end of the slot 22 in the cover 7 whereupon pins 23, 24 on the bolt enter recesses in the frame 5 and the catch 25 enters a notch 29 in the limb 10 to hold it in locking position. At the same time the watch 8 is stopped and the watch 9 started. Access to the receptacle is obtained by an authorized person unlocking and lifting the cover 7 and withdrawing the bolt.
