Title: Process of Producing Alcohols.
IPC: C07C29/124
Filed: 1917-06-09
Abstract: 119,249. Marks, E. C. R., (Du Pont de Nemours & Co., L. I.). June 9, 1917. Alcohols are prepared by reacting with a halogenhydrocarbon on a salt of a higher fatty acid, e.g. sodium stearate, and saponifying the resulting ester. For example, using the apparatus shown in Fig. 1, the reaction vessel 1 is half-filled with stearic acid, the equivalent of solid caustic soda is added, the mixture is heated by the oil-jacket 2 to 200-240‹ C. and a mixture of pentyl and hexyl chlorides is run in from vessel 8 by tube 5 Unchanged chlorides, and olefines produced as by-products, distil over to condenser 15 and receptacle 17. The vessel 1 is then cooled to 150‹ C., caustic soda is added, and the vessel again heated to saponify the esters. The resulting alcohols are distilled off in steam, and the process repeated until the stearate in the vessel 1 has become highly charged with salt, when the mixture is removed, acidified, warmed, and the stearic acid decanted off, and washed for re-use. In a modified construction of apparatus, a reflux condenser is provided to return unchanged chlorides to the vessel 1, while the olefines only pass off to condenser 15.

Title: Improvements in and relating to chlorination of sulfurized esters
IPC: C10M135/06
Filed: 1962-03-05
Abstract: The invention comprises chlorinated sulphurized diesters of alkenylsuccinic acids containing 1 to 15% by weight of chemically bound sulphur and 5 to 30% by weight of chemically bound chlorine and wherein the alkenyl group contains at least 3 carbon atoms and is an aliphatic or alicyclic radical containing at least one olefinic double bond.  They may be prepared by bubbling chlorine through a solution of a sulphurized diester of an alkenylsuccinic acid containing 5 to 30% by weight of chemically bound sulphur in a solvent which is inert to chlorine under the reaction conditions employed until a reaction product having the desired proportions of chemically bound chlorine and sulphur is obtained.  The total amount of chlorine passed should be 1 to 6 parts by weight per part of the sulphurized ester and the chlorinated sulphurized esters so produced may be stabilized by addition of 1 to 15% by weight of an organic oxirane compound.  The sulphurized diester may be obtained by heating an aliphatic or alicyclic olefin containing at least 3 carbon atoms with maleic anhydride to give an alkenylsuccinic anhydride, esterifying the alkenylsuccinic anhydride, and heating the alkenylsuccinate so formed with elemental sulphur at a sulphur to diester ratio of 4: 1 to 15: 1 and preferably at 205 DEG  to 260 DEG C.  The sulphurized diester may be isolated from the reaction mixture by dilution with hexane, filtration, dilution of the filtrate with benzene, treatment with activated carbon, and a final filtration. Specified ester groups are those derived from monohydric alcohols and phenols, alkoxyalcohols, heterocyclic alcohols and dihydric alcohols. The chlorinated sulphurized alkenylsuccinates of the invention are used as lubricating oil additives (see Division C5). Specification 914,661 is referred to.ALSO:Lubricating oil compositions comprise a petroleum distillate boiling above 325 DEG  C. and having a viscosity greater than 50 seconds Saybolt Universal at 38 DEG  C. and at least 0.1% by weight of a chlorinated sulphurized diester of an alkenylsuccinic acid containing 1 to 15% by weight of chemically based sulphur and 5 to 30% by weight of chemically based chlorine and wherein the alkenyl group contains at least 3 carbon atoms and is an aliphatic or alicyclic radical containing at least one olefinic double bond. In the Examples 7 and 8 various sulphurized and chlorinated sulphurized diesters of alkenylsuccinic acids were dissolved in a naphthenic base petroleum distillate lubricating oil having a viscosity of 1120 seconds Saybolt Universal at 38 DEG  C. and the corrosiveness to copper and wear prevention properties of the solutions compared. 1 to 15% by weight of an organic oxirane compound may be initially added to the diester as a stabilizer.

Title: Improvements in or relating to electric immersion heaters
IPC: H05B1/02
Filed: 1944-05-05
Abstract: 593,741. Electric heating. COLLINS, G. H., and COLLINS, H. F. May 5, 1944, No. 8501. [Class 39 (iii)] An electrical heating element comprises an insulated resistance winding 23, in series with a thermostatically-operated switch, both being enclosed in a tube 35 of relatively small depth. The thermostatically operated switch comprises a plate 10 of channel cross-section having an aperture 15 through which a bi-metal switch 30, attached by rivets 33 to the bottom of the plate, can operate, and lugs 13 for clamping the contact carrying assemblies thereto. Flexible strips 16, 27 carry contacts 20, 28 respectively, and are attached to an insulating member 29 (which is also the former for the resistance winding 23) by means of metal strips 21, used in the manner of a lace, passing through apertures 24, and including in the case of flexible strip 16, a metal plate 17 having a bent over lug 19 through which the plate passes a screw 18 for adjusting the position of the said strip. Each metal strip 21 is bent at one end into a tubular form to receive the ends of the resistance element 23. The movement of the bimetal strip in response to an increasing temperature of the tube 35 with which it is in direct thermal contact, causes it to deflect member 27, through the intermediary of an insulating member 3, at a temperature determined by the adjustment of screw 18 to break the circuit by separating the two contacts 20, 28. Screw 18 is made accessible for adjustment after assembly through a hollow boss 37, which fits into an aperture 36 in the tube 35 and which is closed by means of the screw 39 and the cap 42 which can be soldered to the boss.

Title: Improvements in or relating to cameras, particularly television cameras having a lensturret, and control means therefor
Inventor: BABBS CYRUS HERBERT
IPC: H04N5/225
Filed: 1952-04-09
Abstract: 723,872. Lens turrets. PYE, Ltd. April 9, 1952 [April 12, 1951], No. 8625/61. Class 97 (1). [Also in Group XXXVII] A camera lens turret, particularly for a television camera, is rotated, to bring the lenses selectively into operative position, by an electric motor controlled by a manually-operated switch at or remote from the camera, the switch being adjustable to one of a number of positions to complete the motor circuit selectively through one of a number of contact switches operated by the turret so that then the motor has turned the turret to position the selected lens, the turret operates the selected contact switch to stop the motor. The system may be so arranged that the direction of rotation of the turret varies according to the lens selected. As shown the turret K carries lenses 1, 2, 3 and 4 and a cam J engaging one of four contacts E1, E2, E3, E4 appropriate to each lens and connected to an electric supply N1, N2 and a motor M for rotating the turret, through switches controlled by relays R1, R2, R3, which are respectively responsive to different voltages. The relays are controlled by a switch D at the camera or by a switch D1 remote from the camera and connected thereto by suitable cable B, Operation is as follows. If it is desired to substitute lens 2 for lens 1 in the operative position C the arm of the switch D is moved to contact D2. This causes a certain voltage to be applied to the relays through resistances F and G, the voltage being sufficient to operate relay R1 but insufficient to operate the relays R2, R3. Relay R1 closes the motor circuit through switch E2, the turret turning until the lens 2 reaches the position C whereat the cam J operates switch E2 to open the motor circuit. The circuit operates similarly for other positions of the switch D except the position D1 in which none of the relays is operated, the circuit being then completed through the switch E1. Remote operation from the switch D1 is similar, a series of relays R1<SP>1</SP>, R2<SP>1</SP>, R3<SP>1</SP> being additionally provided at the remote station to operate one of the lamps L1-L4 indicating the operative lens. In a modification each switch E1-E4 is arranged to be reversing, i.e. to have three positions, and a suitable cam is provided on the turret so that if selection of the lens immediately preceding the lens in use in the usual direction of rotation of the turret is effected, the motor M is reversed to position that lens. In this modification the selector switch D at the camera is replaced by a series of push-buttons.

Title: Improvements in or relating to the manufacture of hollow metallic barrels and like containers
IPC: B21D17/02
Filed: 1938-03-21
Abstract: 516,280. Making drums and like containers. DEFAUW, M. F. M. March 21, 1938, No. 8569. Convention date, March 30, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 20, 1938]. [Classes 83 (ii) and 83 (iv)] Corrugating; flanging.-In a machine for forming circumferential corugations 13 in a barrel 12 by means of a set of expanding tools 6 operated by a shaft 10, the barrel rests on a base plate 14 which can be raised or lowered to bring the various parts of the wall to be corrugated successively opposite the tools. The reciprocating shaft 10 carries a cone 9 for operating the tools,.and the upward stroke effects lifting of the base plate by pawl and ratchet mechanism 17, 16, additional pawls 20 preventing return of the base plate on the downward stroke. The ring 8 forms a guide for the barrel. Modifications are described in which the base plate is moved by screw and nut mechanism or by fluid operated plungers. The Specification as open to inspection under Sect. 91 describes various machines for corrugating and flanging. In Fig. 1 (Cancelled) sets of dies 1 are actuated by a series of cones 5 picked up in succession by a cam 4 on a travelling mandrel 3. The drum may be supported internally by a set of dies 9 closed by a rotating cam ring. The loose cones may be connected by screws 6 and springs 7 arranged as shown in Fig. 5 (Cancelled). A set of dies 6 may flange the end of the drum, the outer dies may be dispensed with or reduced to a single support arranged opposite the longitudinal seam, and the outer dies may be cut down to co-operate with the inner flanging dies only and one segment may carry the single support. Instead of merely acting as supports the outer dies may form inward corrugations. The desired sequential action may be obtained by spacing the cones relatively to the dies they are to operate and to prevent a die set being operated more than once during a stroke of the mandrel the cones 31, 32, Fig. 8 (Cancelled) may differ in diameter, the corresponding die sections being varied in thickness. A single cone may actuate all the dies and this may comprise a series of removable cam plates carried by a nut. Each set of dies may form more than one corrugation for example three, the outer sections 34, Fig. 15 (Cancelled), being arranged to move axially towards the centre sections 33 as the metal is gathered. This may be effected by the work itself against the action of springs, or fixed cams 38 may effect this movement positively. Spring pins 42 may lock the sections in the converged position during withdrawal, being released at the end of the return stroke by opposed pins 44, Fig. 9 (Cancelled) indicates one order in which a set of corrugations may be formed. This subject-matter does not appear in the Specification as accepted.

Filed: 1946-03-21
Abstract: 609,772. Feeding sheets. H. T. B., Ltd., and TEBBS, G. W. March 21, 1946, No. 8823. [Class 100(ii)] Stopping &c. arrangements.-In a sheetfeeding apparatus in which the sheets are registered on a lay board 1 by means of rising and falling front stops 2, sheet detectors 12 are arranged close to the stops and act to stop the feeding-machine and/ or operate a signal if the detectors 12 are not moved by the advancing edge of the sheet at the correct time. Each detector 12, which is acted upon by a spring 13, normally holds down in the position shown by full lines a lever 15 pivoted at 16 so as to hold the right hand end of the lever in the path of an oscillating sensing arm 19 connected with a tripping or signalling means of known kind. A correctly fed sheet acts upon the detector 12 and the lever 15 is free to be pressed by a spring 24 so as to be moved clear of the arm 19 and thus prevent actuation of the tripping mechanism. If, however, a sheet is not fed, the arm 19 is held, and the tripping mechanism is actuated. The lever 15 is normally reset at the end of each sheet feed by means of a lever 21 which is rocked by the arm 19 on its return motion. This lever 21 acts upon the lever 15 on its return clockwise movement so as to release the pressure of the lever 15 upon the detector 12 so as to enable it to be moved readily by the sheet. The whole apparatus is mounted on a bracket 4 longitudinally adjustable on a rod 5. Specification 356,727 is referred to.
