Patent GB-452662-A (GB)
Title: Improvements in or relating to the manufacture of chlorinated paraffin waxes
IPC: C10G73/38
Filed: 1935-02-26
Abstract: Chlorinated paraffin-wax is separated into fractions of differing molecular weight and chlorine content by short path distillation in very high vacuum, e.g. 10<-2> to 10<-4> mm. of mercury, in apparatus having condensing and evaporating surfaces which are substantially co-extensive and separated by a distance of not more than a few inches.  The mono- and di-chlor compounds can in this way be separated from one another and from the higher chlorinated compounds. If the monochlor compound is desired it is preferable to use a wax of low chlorine content, e.g. 12--15 per cent; if a dichlor compound, a wax of, e.g. 20--26 per cent chlorine content.  A chlorinated paraffin-wax containing 19,6 per cent chlorine on distillation at 10<-4> mm., the cooled glass condensing surface being about 1 inch from the wax, gave a fraction distilling at 85--135 DEG  C. which was largely the monochlor derivative.  The next fraction up to 150 DEG C. was essentially dichlor-paraffin wax.  The residue gave no distillate up to 200 DEG  C. and contained 31,9 per cent chlorine. Specifications 303,078, [Class 32], and 417,659 are referred to.ALSO:Chlorinated paraffin-wax is separated into fractions of differing molecular weight and chlorine content by short path distillation in very high vacuum, e.g. 10<-2> to 10<-4> mm. of mercury, in apparatus having condensing and evaporating surfaces which are substantially co-extensive and separated by a distance of not more than a few inches.

Title: An improved occasional table
IPC: A47B31/04
Filed: 1937-03-02
Abstract: 493,280. Tables. SHARP, W. R. March 2, 1937, Nos. 6223 and 23320. [Class 52 (iii)] A table comprises a top 2 pivoted at one end to an inclined support 1 which at its lower end is pivoted to a base 3 about an axis 5 and stops or abutments 6 interposed between the parts so that the table top may be moved in one direction until the assembly automatically takes up a substantially Z-form, while in the other direction it is freely movable without the necessity of releasing stops or other holding means. As shown in Fig. 1, the top 2 and base 3 are pivoted at 4 and 5 to supports 1 connected by a box 7 so that they may be swung in one direction to fold between the supports, but in the other direction abut against stops 6 on the inner faces of the supports to maintain the parts in the retracted position shown, with the table top horizontal. By pulling forward the top, the parts are moved to the extended position shown in Fig. 2 in which the top rests upon the knees of a seated person. The box 7 provides a container for papers &c. both in the extended and retracted positions of use and when the table is folded and leaned against a wall. Fig. 4 shows a modification in which the stops are replaced by pawls 11, 12 pivoted to the underside of the top and the supports 8 respectively and adapted to engage recesses 10a in the supports and the base. Stops 15 are provided for limiting the angular movement of the pawls so that when the table is unfolded the pawls will drop into the recesses. The hinged ends of the lower frame 10 are tapered so that when the table is folded and placed against a wall the lower frame is pressed against the supports 8. Short legs may be pivoted on the underside of the free edge of the top to rest upon a bed. The top may be shaped to form an ironing table. Fig. 10 shows a dinner wagon, the lower frame comprising a tray 22 on castors and the diagonal supports 24 having a cross-bar 25 forming a handle. A middle tray 26 may be pivoted to the supports 24 and connected by links 27, 29 to the top tray 28 and lower tray 22 so that the trays remain parallel. In this form, one pair of pawls may be dispensed with. The top may be reversible by having grooves along its edges engaging pivot pins projecting from the'support. The supports and the top and bottom frames may be of tubular metal cranked to form the stops or abutments. A pawl pivoted to the free end of the top may engage one of a number of recesses in the support to vary the inclination of the top when it is in the extended position. An abutment on the inclined support may engage the base in both the retracted and extended positions, and to prevent upsetting in the extended position the base may have hinged to it a supplementary frame contacting with the floor.

Title: A method of producing precast concrete products, a machine for performing the same and a concrete block produced by the method
IPC: B28B13/06
Filed: 1966-02-18
Abstract: 1,133,231. Moulding concrete blocks. H. LAIER. 18 Feb., 1966 [20 Feb., 1965], No. 7331/66. Heading B5A. A method of casting concrete blocks comprises depositing a concrete mix from a hopper into moulds, compacting it, depositing the still moist blocks on to a platform and depositing in this way successive layers of blocks one on top of the other; the layers being separated by covering the previously deposited layer with a parting material. A machine for carrying out the method comprises uprights 16, 17 having wheels 29, 30 running on rails 22, 23 (or a flat surface), each column having successive levels 14, 15 at which spring pins 12, 13 are inserted to support a moulding bed 4 which is formed into moulds by a plunger 5. This plunger is attached to a cross-beam 7 raised by a ram 6; beam 7 and bed 4 being vibrated to compact the cement mix, poured on to the latter from a hopper (not shown), by high-frequency vibrators 8-11. As the machine reaches the end of the rails the mould bottom is uncovered and concrete blocks 3 are deposited on a platform 35. The parting layer which may be sawdust, shale oil or a non-wettable plastics wide-mesh grid, is then applied to the top surface of the blocks while the machine returns to the beginning of the rails and the bed 4 is raised. When a pile of say six layers of blocks is built up, a fork-lift truck removes the platform 35, which acts as a pallet.
