Title: Improvements relating to concrete floors and similar slab constructions
IPC: E04B5/21
Filed: 1934-08-15
Abstract: 442,166. Floors. HOLLAND & HANNEN & CUBITTS, Ltd., 1, Queen Anne's Gate, London, and ARNOLDI, F. SCHNEIDER-, 1a, Rheinstrasse, Rodenkirchen, near Cologne, and MECKEL, J., 64, Olpenerstrasse, H÷henberg, Cologne, Germany. Aug. 15, 1934, No. 23550. [Class 20 (iv)] A floor comprises a number of hollow spaces situated between an upper layer of concrete and a lower ceiling layer comprising concrete which, during the pouring of the upper layer, has passed through perforations or reticulations in a member or members defining the upper limit of the hollow spaces. In one construction employing steel or other pre-formed beams, a layer of perforated material, such as perforated sheet metal, wire mesh, or woven wire work, is supported across the tops of the beams, and some of the concrete, which is cast on to this perforatedmaterial to form the upper concrete layer, is adapted to pass through the perforations in the material on to a layer of perforated material supported beneath the beams so as to form the ceiling layer. In another construction, hollow bodies d of perforated material are arranged in spaced relation on a layer c of perforated sheet metal, wire mesh or expanded metal carried by a shuttering b, as shown in Fig. 2. The bodies are tied by wires to the layer c and may be interconnected by hooks or wires. Reinforcing bars e are laid in the spaces between the hollow bodies and concrete f is cast between and above the hollow bodies. The concrete which passes through the perforations in the hollow bodies forms a layer of “" to ¢" in thickness. The hollow bodies may be of woven wire, or they. may be built up of a number of perforated sheets tied together by wire h, as shown in Fig. 4. A further form of hollow body is of cylindrical shape constituted by a perforated wall g and a flanged and perforated top j, as shown in Fig. 7. If desired, one or more hollow bodies may be supported between adjacent I-beams on a layer of perforated material. The floor may be formed of pumice concrete.

Title: Improvements in and relating to coin freed amusement apparatus
IPC: G07F17/34
Filed: 1931-08-22
Abstract: 386,026. Coin-freed amusement apparatus. DIXON, R. H. and DIXON, C. L., 7, Forest Lane, Stratford, London. Aug. 22, 1931, No. 23640. [Class 27.] Relates to a coin-freed amusement machine in which a prize is delivered if a spinning disc stops in a particular position. Insertion of a coin enables the coin-holder h to be rotated by the operating handle, thereby raising a spring-controlled arm k. A notch k<1> on this arm engages a pin l on a spring-controlled arm l<1>, Fig. 4, raising the latter until the arm k is forced out of engagement therewith by a pin q. The arm l<1> then falls, and an impulse is imparted to the wheel d by the engagement therewith of a pawl l<1> carried by the arm l<1>, this pawl being drawn clear by a stop l<5> at the end of the stroke. On the upward stroke of the arm l<1>, a pin l<3> thereon raises an arm m, which in turn raises an arm n, both these arms subsequently falling under the action of springs against the action of a dash-pot p. A projection n<2> on the arm n brings the wheel d to rest, and a projection ml on the arm m either comes to rest on a flange d<1> carried by the wheel d or else enters a slot d<2> therein if the disc has stopped in a favourable position, this being indicated to the operator by the coincidence of a list of commodities on a disc rotating with the wheel d with a fixed list visible through a window. Prize-delivery mechanism.-If the projection m<1> engages a slot, a pin m<2> on the arm m slips over a shoulder u<2> on a pivoted arm u, which moves over and causes a frame s to deliver an article from a pile r. Resetting is effected at the next actuation of the handle, whch moves an arm w so that a notch w<1> therein engages a pin u<1> on the arm u. In a modification, articles are delivered alternately from two adjacent piles by a handle operated by the user, the delivery mechanism being freed by a member connected with the arm m, and means being provided so that only one article can be released at a time. Coin - action, mechanical connection. - The sector-shaped coin holder h can be rotated only when a coin therein serves to disengage a detent h<4> from a stop h<3> thereon.

Title: Improvements relating to machines for making tubing from sheet material
IPC: B29C53/50
Filed: 1953-08-28
Abstract: 741,906. Machines for making paper &c. tubes. KELLER, T. W. Aug. 28, 1953 [June 4, 1953], No. 23762/53. Class 99(2). In a machine wherein a sheet 12 of material, e.g., paper or polyethylene, is wrapped around a former shoe 14, comprising superimposed, verticallyspaced rectangular plates 44, to form a tube 16, mechanical anti-friction means is provided to reduce drag between the shoe and the material, that means including an endless belt 54 of spring wire one flight 56 of which extends parallel to the direction of movement of the material, and that flight over which the material is folded moving with the material. As shown, journalled peripherally-grooved pulleys 46 arranged at the corners of and between the plates 44 carry belts 54 the outer flights 56 of which are parallel to and project beyond the lateral edges 48 of the plates, the sheet material 12 being folded about the flights 56 without being pulled tightly against the edges 48. Additional pulleys may be mounted between the plates 44 to prevent sagging or inward pushing of the flights 56 by lateral contraction of the material 12. A bracket 18 supports the shoe 14 and arms 32 depending from the bracket hold up the side edges 28 of the material to initiate a folding operation, adjustable downwardly and forwardly inclined fingers 36 having crossed lower ends 38 urging the edges into overlapping condition on top of the shoe to form a longitudinal seam 30 which is glued or heat-sealed. A pair of wheels 42 inclined to the direction of movement of the material and adjustably supported on a bracket 40 maintain the edges 28 in overlapped relation until secured together. In a modification, pulleys 82, Fig. 8, and belts 84 are arranged on laterally adjustable bars 74, the inner flights 86 of the belts pressing the material inwardly between the plates 68 of the shoe to form gussets 62 in the tube 60. The pulleys at the entering end of the shoe are smaller in diameter than the remaining pulleys so that the material is progressively urged between the plates 68, or the leading pulleys have axes of rotation spaced further laterally outward of the side edges of the plates 68.

Title: Improvements in or relating to oil-soluble soaps of polyvalent metals
IPC: C09F9/00
Filed: 1959-07-14
Abstract: In the preparation of oil-soluble soaps of polyvalent metals and organic aliphatic or cycloaliphatic carboxylic acids containing more than 6 carbon atoms, by reacting a finely powdered oxide or hydroxide of the metal with the acid, the process is catalysed by the presence of a salt derived from the metal and an aliphatic carboxylic acid containing less than 4 carbon atoms in the molecule and which may be formed in situ.  Soaps derived from linseed oil fatty acids, oleic, stearic, naphthenic, pelargonic, 3,5,5-trimethyl-hexanoic, 2-ethyl hexanoic acids, and acids obtained by the Fischer-Tropsch synthesis and branched-chain acids from oxo-alcohols, and metals such as marium, calcium, cobalt, copper, iron, lead, magnesium, manganese, mercury and zinc are referred to, and the acids containing less than 4 carbon atoms are selected from acetic, propionic, lactic or formic acids.  In examples, the aliphatic carboxylic acid, e.g. acetic or propionic, and the metal oxide or hydronide, e.g. litharge, in solution in an organic solvent or water form the intermediate soap to which the acid containing more than 6 carbon atoms, e.g. naphthenic, and ethylhexanoic acids in white spirit or xylene is added and the product separated; or alternatively the higher acid, e.g. naphthenic or saturated iso-carboxylic acids, is mixed with the metal compound, e.g. litharge, cobalt hydroxide, and calcium or mercuric oxides, in a solvent such as white spirit, and acetic or formic acid added with or before the metal compound, the lower acids and water are then distilled off.  Specification 451,735 is referred to.
