Title: Improvements in sheet separating and forwarding machines
Inventor: FAWDRY CHARLES FREDERICK
IPC: B65H9/12
Filed: 1963-04-26
Abstract: 1,058,134. Feeding sheets. H. T. BACK. HOUSE. April 27, 1964 [April 26, 1963], No. 16593/63. Heading B6B. Sheet forwarding apparatus for feeding individual sheets from the top of a pile substantially in the plane of the sheet comprises two or more spaced suction grippers 135 carried by swinging arms 121, the length of at least one arm 121 being adjustable so that the length of travel of one gripper may be varied relative to that of the other gripper. The suction grippers 135 are spaced apart on a cross-bar 35. The latter is supported at each end by a ball joint 200 at the lower end of an arm 121. One arm comprises telescopic members 202, 203 spring- urged apart. Member 203 is prevented from rotational movement in the sleeve 202 by lugs 206 thereon riding in slots 207 in the sleeve. Rotation of a handle 220 over a graduated scale 221 is transmitted via a rod 219, gears 218, and members 212-216, to a member 210 screwed into the member 203, thereby varying the length of the arm. The other arm is fixed in length. Said arm and the sleeve 202 are secured to opposite ends of a shaft 122, Fig. 3. Shaft 122 is oscillated by means of a reciprocating rod 126 through a pivoted bell-crank 232 and an arm 230 fixed to the shaft. The bell-crank 232 may be rocked by an adjustable nut 233 to vary the radial distance from the centre of the shaft to the rod and hence the distance moved by the cross-bar 35. The suction grippers are supported from the cross-bar or arms 136. Said arms are free to pivot upwardly a limited amount from the position shown in Fig. 2.

Title: Improvements in or relating to the application of liquids to yarns or threads
IPC: D01H13/30
Filed: 1929-05-30
Abstract: 337,433. British Cel,anese, Ltd., and Taylor, W. I. May 30, 1929. Spindle apparatus; moistening, sizing, and treating yarns or threads.-Liquid is applied to travelling yarn or thread while it is passing over the circular edge of a guide member round and in contact with which it is revolving so that the liquid is swept from the edge by the passage of the yarn. The invention is particularly suitable for sizing, dyeing, or dressing yarns or threads of cellulose acetate or other organic derivatives of cellulose, and may be applied while twisting and winding in the production of such yarns by the dry or wet method or in any subsequent stage of manufacture. As shown, the invention is applied to cap spinning apparatus, Fig. 2, and to box spinning apparatus, Fig. 4, in each case the liquid being fed from a reservoir 8 to the side of the edge of the guide member, cap 5 or guide funnel 15, from which the thread leaves. The supply may be controlled so as to give a uniform or an. intermittent application, the latter method enabling multi-coloured or shading effects to be produced by using different dyes in compartments of the reservoir. The reservoir may be mounted' on the top of the cap or inside as shown by dotted lines 20. The bottom of the box may be recessed and apertured to facilitate the escape of surplus liquid, or may be provided with a recess 31 in a false bottom 30 for the same purpose. According to the Provisional Specification the liquid may be fed through a passage in the cap spindle.

Title: Process for the manufacture of polyethylene or polypropylene resin powder
IPC: C08J3/12
Filed: 1961-05-08
Abstract: A process for the manufacture of a polyethylene or polypropylene powder comprises dissolving the resin in a liquid chlorinated hydrocarbon at an elevated temperature, cooling the solution until it is solid, grinding with a substantially equal weight of water in the presence of a non-ionic surface-active agent (e.g. polyethyleneglycol - nonyl - phenol ether) and a neutral detergent in the form of a cationic surface active agent (e.g. an alkyltrimethyl ammonium chloride) in an amount of 2 to 10% of the whole mixture, to produce a suspension of the solidified resin solution from which crystalline resin particles are gradually precipitated, the crystal particles being collectively separated from the emulsion of the solvent and the particles then being subjected to washing with water, squeeze drying and final drying (e.g. in a filter press and a centrifugal separator) to give a powder in the range 100 to 400 Tyler mesh. In an example, trichloroethylene or tetrachloroethylene may be used as the chlorinated hydrocarbon.

Title: A process for the preparation of chloral from choral alcoholate
IPC: C07C45/51
Filed: 1947-06-24
Abstract: Chloral is obtained by reacting chloral with a carboxylic acid the ethyl ester of which preferably has a lower boiling point than chloral.  Mixtures containing chloral alcoholate, e.g. the crude product obtained by chlorination of ethanol, may be used as starting material.  Specified carboxylic acids are formic, acetic, propionic, butyric, isobutyric, lactic, oxalic and benzoic acids. The ester produced along with the chloral may be separated by distillation. The reaction is preferably carried out at 50-100 DEG  C. and in the presence of a minor proportion by weight of a volatile mineral acid, e.g. hydrochloric acid.  The process may be carried out batchwise or continuously and atmospheric or other pressure may be used.  In an example a crude chlorination product obtained by chlorinating ethanol and containing chloral alcoholate, chloral and hydrochloric acid, is mixed with acetic acid and immediately distilled, yielding first an ethyl acetate containing fraction and then a fraction consisting of pure chloral.  Specification 605,318 is referred to.

An unloading valve for hydraulic systems consists of a by-pass valve plunger 5 controlling communication between an inlet 6 and a bypass port 9, a passage 10 with a choke 11 interconnecting the two ends of the plunger whereby the latter is held by a spring 7 in its closed position when in hydraulic balance, but is opened by inlet pressure when an outlet 37 from a chamber 3 is vented by a pilot valve plunger 25, and further outlets 36, 38 controlled by movement of the by-pass plunger to ensure decisive operation of the latter. Opening of the outlets 36, 38 is effected by an annular recess 13 in the by-pass plunger connected with the passage 10. The pilot valve plunger is urged upwardly against a spring 26 by pressure in the hydraulic system admitted through a port 24 and connects the outlets 36, 37, 38, through passages 29, 30, 27, 28, with an outlet 35. A spring-loaded, flanged sleeve 17 on the lower end of the by-pass plunger ensures that a substantial pressure is maintained upstream of the plunger to enable it to complete its opening movement. Alternatively, a relief valve may be fitted to the by-pass port 9 for this purpose.

Abstract: 1369536 FET data storage cells INTERNATIONAL BUSINESS MACHINES CORP 17 April 1972 [17 June 1971] 17532/72 Heading H3T  A capacitor Cs used as a data storage cell is switched between high and low capacitance values to represent the two binary stored values. A write line 12 is taken positive to turn on a F.E.T. Q 1 , and a bit line 10 is taken positive to charge Cs if a 1 is to be stored, or held at Ov if a 0 is to be stored. To read, Q 1  is held off by Ov on line 12 while a read line 14 goes positive. Only if a 1 is stored will Q 2  conduct and transmit the potential on line 14 to the bit line 10 where it operates a sense amplifier. Bootstrap action overcomes Q 2  threshold. In an alternative readout arrangement, Fig. 3 (not shown), Q 2  conducts when a 1 is stored (as before) but in this case it earths the bit line 10 through a third F.E.T. Q 3  turned on by the read line 14. The fabrication of the Fig. 1 circuit (Figs. 4, 5 not shown) uses silicon gate techniques. Source and drain regions (30, 32) of Q 2  are N diffusions in a P substrate (34) carrying a metal backplate (50). Q 2  gate (27) is connected by metallization (46) to both Q 1  source (40) and an electrode (28). When electrode (28) is made sufficiently positive, a negative charge forms under it in the substrate, neutralizes the rectifying junction of the source (30) and forms therewith the second plate of capacitor Cs, of which electrode (28) constitutes the first plate.
