Title: Improvements in devices for ensuring the safe custody of clothing luggage, valuables, or the like
IPC: G07F17/12
Filed: 1919-11-06
Abstract: 158,961. Werner, W. Nov. 6, 1919. No Patent granted (Sealing fee not paid). Luggage and parcel holders. - Lockers for the safe keeping of property are provided with means for preventing the withdrawal of the key until a coin has been inserted comprising a bell-crank lever i the end n of which serves to block the keybit while the other end carries a coin-pocket k. When moved by the weight of a coin the part n releases the key-bit and is moved into contact with a spring-pressed bar p having a notch s. By pressure on a push q, the key having been withdrawn, the bar is moved so that the notch s comes opposite the lever, which moves still further, allowing the coin to drop, and then returns to its locking position. Fig. 4 shows an arrangement of such lockers a in a railway carriage.

Title: Preparation and use of hydrocarbon conversion catalysts
IPC: C07C5/27
Filed: 1965-07-01
Abstract: Isomerization, alkylation and other hydrocarbon conversion processes are effected in the presence of RSbF6 on a particulate solid carrier (where R = hydrogen, alkyl or cycloalkyl). Preferably the feed contains C2-12 hydrocarbons e.g. n-pentane, n-hexane, methylpentanes, n-heptane, and methylhexanes, and is free from unsaturated compounds, benzene, water and sulphur.  Examples described the preparation of C6H11SbF6 and its use to isomerize n-pentane to iso-pentane. Isobutene which remains unchange at the end of the reaction, may be used as an isomerization medium.ALSO:Compounds of formula RSbF6 are made by bringing HSbF6 into contact with a suitable hydrocarbon at room temperature.  [R=alkyl or cycloalkyl].  Particularly suitable hydrocarbons are saturated cyclic hydrocarbons (naphthenes), e.g. cyclopentane, cyclohexane, and/or methylcyclohexane.  Examples describe the preparation of methyl cyclopentenyl hexafluorantimonate.ALSO:HsbF6 on RSbF6 (where R = alkyl or cycloalkyl) is supported on a solid inert carrier e.g. metals, alloys, refractory oxides, salts on polymers.  Specified carriers are Pt, Al, Pt-Au, Ni-Mo, Ni-W, Al-Mg, polyethylene, polytrifluorochloroethylene, P.T.F.E., copolymeric P.T.F.E. and hexafluoropropylene, SbF3 and AlF3 if desired coated on Al2O3, SiO2, SiO2-Al2O3, SiO2-MgO and combinations thereof with Cr2O3, BrO3 and ZrO2.  Naturally occurring materials specified are bauxite, Kaolin and diatomaceous earth.  The catalyst may have a surface area of 200 sq.m/gm.

Title: Improvements in or relating to machines for grading articles by weight
IPC: B07C5/22
Filed: 1932-10-07
Abstract: 412,971. Grading eggs &c. by weighing. HISCOCK, E. J., Union Works, Union Street, Trowbridge, Wiltshire. Oct. 7, 1932, No. 28009. [Class 143.] An apparatus for grading eggs, tennis balls, packeted goods, &c., by weight comprises a series of weighing devices each responsive to a different weight, and gripping devices for transferring articles from one weighing device to another and releasing the articles automatically for the weighing operation. The eggs are placed in recesses 2 in a rotary platform 1 actuated intermittently from a motor-driven shaft 30, and are thereby presented successively, in line with a row of scale pans 4-7, alternating with fixed guide platforms. The shaft 30, acting through links 28, 25 and a rocking lever 23, reciprocates a carriage 13 and bar 16. The carriage 13 carries a number of gripping devices 11. During the rocking movements of the lever 23 the gripping devices pick up the eggs and transfer them step by step along the row from the rotary platform to the scale pans. Eggs of sufficient weight tilt the scale pans and roll into collecting trays. Eggs remaining on the right-hand scale pan are displaced by the eggs carried forward by the right hand gripping device. The gripping devices are opened and closed at the appropriate times by the small vertical movements of the bar 16 operating on the grippers in the manner shown in Fig. 5. When sorting tennis balls, instead of employing a rotary platform 1, the balls are fed down a shoot by detents actuated by the carriage 13. A permanent magnet may be arranged beneath the scale pan to assist its tipping. A rubber stamp 57 carried by a linkage 60 is moved by the reciprocating carriage 13, from an inking pad 62 so as to stamp each egg as it is carried round on the rotary platform.

Abstract: 483,318. Feeding stoppers. MEADOWCROFT & SON, Ltd., W., and MEADOWCROFT, W. Oct. 16, 1936, No. 28101. [Class 78 (i)] [Also in Group XVII] A device for feeding screw stoppers to a single or multiple head machine for screwing them into bottles &c., comprises a stationary hopper A having a depending tube D in which an agitating member E is reciprocated to disturb the stoppers F in the hopper so that they descend. through a passage in the member E with their screwed portions directed upwards or downwards. As shown, the tubular member E is reciprocated from a rod E<3> through an arm G, rock-shaft H, arms J, links K and bellcrank levers L attached to links M on pins N on the member, and two jaws T pivoted on lugs e on the member E project through.slots therein and in the tube D and are formed with tails t to which springs U are fastened. The other ends of the springs are fastened to pegs e<2> on the member E and the springs normally force the jaws into position to grip the lowermost stopper in the member E but when the member moves to its bottom position the tails t engage posts S and turn the jaws so that the stopper is released to fall through a collar Q on to a channel R along which the stoppers are fed to the screwing head by a slide P actuated from the arms J ; the stoppers delivered with their screwed portions directed upwards may be subsequently turned over in the manner described in Specification 483,472. A tube V inside the hopper prevents an accumulation of stoppers above the member E.

The extrusion may entirely comprise material from the extruder 26, but in the Fig. 2, embodiment this is applied as a pencil covering to a pencil lead composition delivered by a screw 20 through an extrustion passage 22, extending axially through the member 21 and with respect to which the die 23 is radially adjustable, by 120 degrees spaced apart screws 39. The die 23 is attached to a member 35, which is screw threadedly engaged with the die head 24 and 36 and provided with bland bores 37 for engagement by rotating means to effect axial displacement of the die 23 towards the member 21 to vary the depth of the frusto-conical passage 31. The depth of the frusto-conical passage may alternatively be adjusted by displacement of the die head with respect to the die. The die 23 is slideable within the die head 24 at a seal 38. The inlet 29 is surrounded with heating elements 28. The material may also be extruded around a colour pencil or eraser pencil core. The thermoplastics material by comprise polyolefins, A.B.S. polymers, cellulose thermoplastics, polymethanes, polyamide, polycarbonate, polyvinyl chloride, chlorinated polyvinylchloride, ethylene vinyl acetates, polyacetal, and P.V.C. modified ethylene vinyl acetates, and the materials may be coloured by pigment or may be foamable by colouring agents such as diphenyl-3, 3-disulphahydrazide, hydrocarbons, fluorinated hydrocarbons, argon, nitrogen, and carbon dioxide. The quantity of material supplied to the extrusion passage may be periodically changed to produce a correspondingly thickened or constricted section. The material may also be extruded around one or more cores of circular, slit, or trapezoidal shape, or around a preformed wire, rope, tube, band, fabric web, or a foil, or around members delivered through a plurality of mandrel bores, and more than one layer of material may be sequentially applied during passage through the die.
