Abstract: 473,311. Memorandum appliances. STANDARD REGISTER CO. April 9, 1936, No. 10588. Convention date, April 12, 1935. [Class 16] [Also in Group XVI] In a stationery-feeding device for use in typewriters, and other recording-machines, such as autographic registers, of the kind comprising a roller or other carrier provided with pins for engaging perforations in the stationery, the pins after entering the perforations move to a position in which, by virtue of their shape, dislodgment of the stationery is prevented, and, before withdrawal, the pins move to a position permitting free disengagement of the stationery. The platen 10 shown in Fig. 2 is provided at each end with a wall 22 supporting spring-retracted pivoted pins 28 each formed, as shown in Fig. 7, with a shank 28, a T-head 30, a pivot 26, and a finger 32 for co-operation with a normally stationary cam 34. The cams are arranged in the manner described in Specification 408,125, [Group XVI]. The stationery may be provided with T-perforations. During rotation of the platen, the pin approaching the printing line is projected, the head 30 passes through the cross-part 44 of one of the T-perforations, and the shank 28 enters the vertical part of the perforation. On reaching the top of the platen, the pin is retracted by its spring and is disengaged from the perforation. When the stationery is provided with round or oblong perforations, the heads 30 may be omitted from the pins. The pins may be mounted on an endless chain passing over sprockets, a stationary cam or bar co-operating with the fingers 32 to control projection and withdrawal of the pins. The platen 10 shown in Fig. 13 is provided at each end with a wall 22 supporting pivoted spring-urged carriers 80 in which are slidably mounted spring-urged T-headed pins 86. The carriers are provided with fingers 94 co-operating with a stationary cam 96, and the pins co-operate with a stationary cam 92. During rotation of the platen, each carrier is swung outwards with its pin by means of the cam 96, and the pin is projected and then permitted to drop by means of the cam 92. Before the pin is swung inwards, it is again projected by the cam 92. In another construction, the pins are formed with a hook for engaging the perforations, a stem cooperating with a stationary cam, and a pivot, the hook being concentric with the pivot. In another construction, the radially and arcuately movable pins described in Specification 472,497 are provided with hooked ends. Specifications 372,980 and 409,162 are referred to.

Title: Organometallic compounds
IPC: B60L15/34
Filed: 1961-03-28
Abstract: Unsaturated aluminium-containing polymers containing on average 8 to 20 aluminium atoms per molecule and having the formula <FORM:0926699/IV(a)/1> where R represents alkyl or alkenyl groups, X represents an alkylene group, Y represents an alkyl or alkenyl group or an p  alkylene group attached to a monovalent aluminium hydrocarbon radical and n is at least 4, may be prepared by reacting an aluminium trialkyl with isoprene in an inert atmosphere until at least two-thirds but not all of the alkyl groups are displaced by isoprene and heating the reaction product in an inert atmosphere until at least 80% but not all of the isoprene is saturated.  The preferred aluminium trialkyl is aluminium triisobutyl.  The products may be employed with metal halides in the formation of olefin polymerization catalysts, e.g. for the polymerization of ethylene, propylene and butene-1.  Specified metal halides are titanium tetrachloride, titanium trichloride, titanium tetrabromide, zirconium tetrachloride, zirconium tetrabromide, vanadium tetrachloride, vanadium trichloride and vanadium oxytrichloride.  The catalysts are preferably heated, e.g. to 100 DEG  to 300 DEG C., prior to or during use.  Polymerization is preferably effected in the presence of an inert hydrocarbon solvent such as heptane, cyclohexane, benzene and toluene.  Examples describe the preparation of an aluminium polymer by heating aluminium triisobutyl and isoprene in decahydronaphthalene in the presence of nickel acetyl acetonate and the use thereof with (I) titanium tetrachloride in the polymerization of ethylene and (II) titanium trichloride, prepared by the reduction of titanium tetrachloride with aluminium triisobutyl, in the polymerization of propylene.

Title: Improvements in or relating to Penning Pump Power Supplies
Inventor: ENGLISH JAMES
IPC: H02M7/10
Filed: 1967-03-10
Abstract: 1,168,324. Supply systems for consuming devices; rectifying; protective arrangements. EDWARDS HIGH VACUUM INTERNATIONAL Ltd. 8 March, 1968 [10 March, 1967], No. 11412/67. Heading H2F, H2H and H2K. Power supply for a Penning pump includes a transformer, to the secondary 8 of which is connected a bridge rectifier voltage doubler circuit. The transformer has a choke 6<SP>1</SP> in series with its primary 6, and the output from the rectifier bridge 9, 10, 11, 12 appears at terminals A, B which are connected to corresponding terminals C, D of an output unit. Further terminals E, F are connected to the pump electrodes. Across the terminals C, D are connected a neon tube NT and a thermistor Rt which limits occasional surge currents in the pump. If frequent arcing occurs, the thermistor heats up and does not provide protection, so a control circuit, Fig. 3 (not shown), is connected to terminals 1-5. This circuit includes an ammeter and a transistor switching arrangement which can, through a relay, open a switch RLA in the transformer primary circuit. Two forms of current protection are provided. Firstly, frequent high current surges cause a sufficient current to flow through terminal 5 to switch on two transistors successively and so activate the relay. An RC circuit affords a time delay of, say, ten seconds before switching occurs, and two resistors provide positive feedback to the first transistor. If the mean current during arcing is insufficient to cause switching in this way, an alternative form of protection is provided in that successive pulses charge a capacitor which eventually triggers the transistors as before. The capacitor discharges through resistors if the pulses are spaced further apart.

Title: Improvements in means for automatically stopping stranding, cabling and rope making machines
IPC: D07B7/08
Filed: 1936-04-22
Abstract: 474,041. Stranding cabling and ropemaking machines. LARMUTH, J. H. April 22, 1936, No. 11467. [Class 109] Relates to electrically operated stop-motions for stranding cabling and rope-making machines, operative when the supply of wire &c. breaks or otherwise fails. Each bobbin cradle 2 is provided with a roller 37 mounted on a swing bracket 34 and resting on a wire &c. 5. If the wire breaks or runs slack the bracket 34 drops, carrying with it a weighted lever 41. A lug 43 on the bracket thus strikes a lever 46 mounted in a box 16. The lever 41 strikes a pin on the bracket 34 with its surface 45. This impact completes the displacement of the lever 46. An angle lever 17 is pivoted within the box 16 and one end projects outside where it can be struck by a feeler 15 on the bobbin, when the wire &c. on the bobbin has been reduced to a minimum number of coils. The lever 17 acts, through a compression spring 18, on a contact 19 provided on a rod 20 projecting outside the box and mounted in the casing. A spring 21 maintains the contact in withdrawn position. The lever 17 normally holds a locking lever 24 out of action, as shown, a roller 23 carried by an extension 22 of the lever 17 resting against a surface 26 of the lever 24. When the lever 17 is displaced, either by the lever 46 or the feeler 15, the contact 19 is projected on to a ring 29, thereby closing a circuit which includes the knock-off motion. The lever 24 when released is moved by its spring 25 to a position where it locks the lever 17 in its inactive position. According to the way the lever 17 was tripped in the first instance, the roller 23 runs up surfaces 27 or 28 and in either case assists the movement of the lever, out of the path of the feeler 15. The lever 17 acts on the contact rod either directly, as shown, or through connections 30 . . 32. A part 33 of the lever 30 projects through the box 16 and can be used as an aid to resetting the parts.

Title: Improvements in or relating to the treatment of regenerated cellulose textile materials
Inventor: SLOAN FREDERICK RICHARD WILFRE
IPC: D06M15/423
Filed: 1962-03-26
Abstract: Textile materials comprising at least some fibres of regenerated cellulose are crease-proofed, stiffened and rendered dimensionally stable by treating them with a cross-linking agent, e.g. formaldehyde, dimethylol ethylene urea, dimethylol propylene urea, glyosol, an acetate of a dialdehyde with a monohydric alcohol or of a monoaldehyde with a polyol or hemiacetol, and mercerising them, e.g. with caustic soda.  The treatment with the cross-linking agent may be effected in the presence of an acid catalyst, e.g. a polyester having free acid groups and prepared from sabacic, maleic, succinic or phthalic acid or an anhydride thereof with a glycol or glycerol.  The textile materials may also be treated with a film forming polyol or an alkali-soluble cellulose ether and bleached with sodium chlorite prior to mercerisation.  The mercerisation may be applied to a fabric whose constituent yarns are of identical and uniform composition and may be accompanied or followed by stretching or it may be applied to a fabric whose constituent yarns are of differing and or non-uniform composition, shrinkage being permitted to occur during mercerisation to produce a bulked fabric.  In the production of bulked fabrics the yarns may be of uniform but differing composition, some of the yarns being composed of regenerated cellulose fibres which have been treated with the cross-linking agent or some of the yarns being uniformly composed of regenerated cellulose fibres, the other yarns being of different origin.  In this case the cross-linking agent may be applied to the regenerated cellulose fibres, to the yarn composed of regenerated cellulose fibres or to the fabric after weaving. Alternatively the fabric may be composed of yarns which have been cross-linked to a differing extent.  In the production of bulked yarn the mercerisation may be applied to yarns composed of regenerated cellulose fibres which have been treated with a cross-linking agent together with fibres of non-cellulosic origin or of fibres of regenerated cellulose which have been cross-linked to differing extents.
