Title: Improvements in and relating to doors for vehicles
IPC: B60J5/06
Filed: 1957-10-15
Abstract: 872,783. Doors for passenger vehicles. TATTER, J. W. Oct. 15, 1957 [Oct. 16, 1956], No. 32236/57. Class 103(2). [Also in Group XXV] A hinge connecting a vehicle door with a vehicle body comprises a member hinged to the door and the body on separate hinge axes, means being provided for releasably locking the member to the door or the body. The member 14, Fig. 3, is hinged to the body 11 at A and to the door 13 at C and normal hinging occurs about the axis A only, the member being locked to the door by a keeper 14d, Fig. 10, which enters a slot 30 in the edge plate 20 of the door and is held therein by a spring-loaded latch bolt 34. The door is carried by two similar hinge members 14, 15, and the bolts 34 are simultaneously released by a cable 37 attached between them which passes over pulleys 38 and is pulled by a rod 40 which extends across the width of the door and is adjustably connected to a link 46, Fig. 12, pivoted to a bracket 45 forming part of a guide 43 secured to the other edge 44 of the door. The link 46 is actuated by pressing a button 42 slidable in the guide. A similar push button actuator is provided on the inner panel 13a of the door and engages an intermediate part of the rod 40. Alternatively, Fig. 14 (not shown) the hinge members may be locked by a pair of latch bolts connected to the rod 40 through bellcranks. An electrical release mechanism is also described in which the cable 37 or the bellcranks are operated by a solenoid. A stay bar 61, Fig. 9, pivoted at one end to the vehicle body, enters a slot 63 in the edge plate 20 of the door and passes between a spring loaded locking pin 70 and a lug 71 which engage in top and bottom grooves 68, 67, in the other end of the bar to hold the door open during normal hinging about the axis A. A cable 64 wound on a spring loaded reel within the door is attached to the grooved end of the bar. When the hinge member 15 is unlocked and begins to move. away from the plate 20 one arm of a bellcrank 75 which normally abuts the hinge member through a slot 77 in the plate is forced by a spring 76, which is stronger than the spring loading the pin 70, to extend through the slot while the other arm 78 of the bellcrank lifts a link 79 to disengage the pin 70 from the groove 68. The stay bar 61 can then pass out through the slot 63. On closing the door the stay bar is guided back into the slot by the cable 64. In a modification the hinge members are locked to the vehicle body and normal hinging occurs about the pivot between the door and the members. A small body panel is mounted on each hinge member to cover the opening through which the hinge member projects in the unlocked position.

Title: Improvements in liquid oxygen explosives
IPC: C06B43/00
Filed: 1955-11-14
Abstract: The combustible material, for a liquid oxygen explosive (see Group XXI), contains a major proportion of dry powdered starch size, which may be prepared by cooking starch with water until at least partly hydrolysed, drying, and grinding.  Fine grain starch size may be obtained by spraying starch size solution into a hot dry atmosphere. The starch size should be at least 55 per cent of the combustible material, and any balance may be raw starch.  The starch size should be fat free, either by removing fat contents, or by using starches from roots, e.g., manioc or potato, and should be at least 30 mesh size, and 0,3-0,75 apparent specific gravity.  The powdered starch size may be compressed, under at least 14 kgm./sq. cm. into pellets with, or without, channels, such as an axial bore.

A teaching device comprises a box containing a stack of sheets each being withdrawable from the box and bearing questions, two or more possible answers to each question and an answer indicating or marking area associated with each question the box including marking means for indicating in the answer area a chosen answer and a window which allows at least one question at a time, and the possible answers to the question to be viewed, and also allows the marking area corresponding to an already attempted question to be viewed, the device also includes non-return means for preventing re-insertion of a sheet into the box. As illustrated two questions 53 and three possible answers 54 to each question and the answer area 55 to the upper question are viewable through a window 39. A student's selection is indicated by depressing a button A, B, C impregnated with ink or co-acting with an ink ribbon. Alternatively the marking means may be a piece of carbon paper or other pressure sensitive marking material or the inside of the box. The correct answer to each question is indicated by a circle 56, thus the student has answered the uppermost question in the window incorrectly. Each answer area may be arranged below the corresponding question area 52. The non-return device comprises resilient tongues (31), (Fig. 2, not shown) which co-act with perforations 59 in the sheets. Each tongue may have a second tongue punched therefrom (Fig. 4, not shown). The non-return device may extend the whole length of the box, and it may be comprised by two strips of elastically compressible material or by unidirectional rollers.

Title: Improvements in or relating to a method for coagulating an unsaturated organic compound sulfur dioxide resin
IPC: C08G75/22
Filed: 1952-12-24
Abstract: A method for coagulating an unsaturated organic compound-sulphur dioxide resin latex comprises intimately admixing it with a finely divided, solid, unsaturated organic compound-sulphur dioxide resin in the wet or dry state at a temperature not in excess of 65 DEG  C., following which the coagulated resin composition may be diluted with water and heated to 75 DEG  C. to increase the particle size.  The latices may be prepared from unsaturated organic compounds such as butenes, pentenes, octenes, 4-cyclohexylbutene-1, cyclohexene, acetylenes, allyl alcohol, vinyl acetate, allyl ethyl ether, o-allylanisole, o - allylphenol, p - bromoallylbenzene, methyl undecylenate, undecylenyl alcohol, undecylenic acid and acrylonitrile.  The coagulating resin may be substantially identical with the resin of the latex and may amount to 5 to 20 per cent of the latex, the higher proportions being used at lower temperatures. Known coagulating agents such as acetic acid, potassium acetate and magnesium sulphate may be used in conjunction with the dry, finely divided resin and the process may be carried out continuously, a portion of the resin produced being recycled to the coagulation zone to effect coagulation.  In example IV the resin latex is produced by heteropolymerization of sulphur dioxide and a 1-butene/acrylonitrile blend using ammonium nitrate as catalyst and sodium lauryl sulphate as dispersing agent.  Moulding the dried products results in clear specimens.  Specifications 686,446 and 695,117 are referred to.

[Class 86] [Also in Groups V and X] Concrete &c. is moulded by subjecting the material to the vibrations of a plate 7 through the perforations of which the material and reinforcements 8 pass while the plate rises progressively. Horizontal reinforcements also may be embedded in the concrete in the mould or frame 5. The top of the moulded block may be profiled by vibrating a solid plate beneath the perforated plate 7. The Specification as open to inspection under Sect. 91, describes also the use of a solid plate which is vibrated on the material in a mould, reinforcements being fixed in the bottom of the mould, and the production of continuous pieces between the side walls of a moulding-box by traversing a solid or perforated vibrating plate over the surface of the concrete as the work progresses, the leading edge of the plate being inclined upwardly. This subject-matter does not appear in the Specification as accepted.
