Abstract: 551,826. Acylhalides. DU PONT DE NEMOURS & CO., E. T., and CALCOTT, W. S. Sept. 8, 1941, No. 11442. [Class 2 (iii)] In the production of acylhalides by the treatment of non-gaseous hydrocarbons containing at least one unsubstituted methylene group with a mixture of sulphurdioxide and chlorine or bromine, a mixture of carbonmonoxide and chlorine or bromine, carbonylchloride, carbonylbromide, sulphurylchloride, sulphurylbromide, oxalylchloride or oxalylbromide, the reaction zone is irradiated with a low temperature vapour lamp which operates at a temperature below 150‹C. Preferably the lamp is of the fluorescent type in which the ultraviolet radiation is converted into visible radiation by means of fluorescent material such as calcium tungstate, magnesium tungstate, zinc silicate, zinc beryllium silicate, cadmium silicate and cadmium borate. Manganese may also be present as an activator of the phosphorescent material. In examples : (1) a neon vapour lamp is used in the treatment of a paraffin base mineral oil with sulphur dioxide and chlorine and cyclohexane with phosgene : (2) a paraffin base mineral oil exposed to the radiation from a mercury vapour Cooper Hewitt fluorescent lamp is converted into a mixture of sulphonylchlorides by treatment with sulphurdioxide and chlorine, and then hydrolysed with caustic soda : (3) cyclohexane, n-heptane, cetane and a mineral oil are treated with sulphurylchloride while subjected to radiation from a Cooper Hewitt fluorescent lamp, small quantities of mercaptothiazoline, pyridine or quinoline being added : (4) cyclohexane, cetane, dodecylbenzene and paraffin wax are treated with oxalylchloride while subjected to a similar radiation : (5) a non-fluorescent Cooper Hewitt mercury lamp is used in the treatment of a paraffin base mineral oil with sulphur dioxide and chlorine and the treatment of pinene with oxalylchloride. The sulphonylchlorides may be separated from the unreacted oil by treatment with a solvent such as liquid sulphurdioxide. The chlorine and/or sulphurdioxide may be used in the liquid state. The following starting materials are mentioned : n- and iso-pentane, hexanes, octanes, octadecanes, match wax, scale wax, wax distillates, cyclopentane, cyclohexane, ethylcyclohexane, dodecylcyclohexane, menthane, camphane, pinane, naphthenes, propylbenzene, decylbenzene, octylnaphthalene, dodecylnaphthalene, triamylbenzene, dioctylbenzene, didodecylnaphthalene and other alkylated aromatic hydrocarbons derived from chlorinated petroleums and benzene, xylene and methylnaphthalene. The Provisional Specification mentions the treatment of methane, ethane and propane and the use of low temperature lamps containing rare gases. Specifications 545,521 and 547,101 are referred to.

IPC: D06F15/00
Filed: 1922-04-26
Abstract: 180,651. Adams, F. A. May 21, 1921, [Convention date]. Addition to 178,855. Washing-machines with plungers and dollies having both rotary and axially-reciprocating motion.-Relates to the clothes-washing machine described in thu parent Specification wherein an hydraulic motor operates an agitating medium, and consists principally in insulating the motor from the hot water in the receptacle and providing a yielding drive for the agitating apparatusto prevent the clothes being damaged. In the receptacle 1 for the clothes and hot water are mounted the agitating cups 2 fixed to a rod 3 which carries at its lower end a piston 4 working in a hydraulic cylinder 5 which is provided with ports 7, 8, governed by a valve 18 so as to give vertical reciprocating motion to the cups. Around the cylinder is an air-jacket 9 with holes 12 and 12<a> giving a circulation of air around the cylinder and preventing heat from passing to it. Rotary motion is imparted to the cups by a loose sleeve 13, Fig. 3 on the, rod 3 having a slot 14 engaging with a fixed pin 15 and a corrugated base 16 with leather washer 17. The top of the piston is also corrugated and during the up-stroke friction between the sleeve and the piston is sufficient to enable the sleeve to carry the piston, and hence the cups, round; during the down-stroke the sleeve alone rotates back to its original position. If the clothes become entangled, their resistance overcomes the friction of the friction of the washer 17 and rotation of the cups ceases. Rubber or other resilient buffers for the valve rod 18 are fitted in sockets 34 formed in the sheet-metal heads at the end of the arm housing. The legs supporting the receptacle are adjustable in sleeves fixed to the base.

Title: Record card feeding means
IPC: G06K13/103
Filed: 1955-04-26
Abstract: 770,244. Feeding cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 26, 1955 [May 21, 1954], No. 11992/55. Class 117 [Also in Group XIX] A card feeding mechanism for feeding cards one at a time from the bottom of a stack in a hopper 12 comprises a card feed head 36 having on its upper surface a card feed knife 41 for engagement with the rear edge of each card in turn, an oscillating rocker arm 45 mounted for pivotal movement about an axis disposed below the hopper and means for securing the feed head to the arm. The hopper consists of a front wall 16, a bottom wall 17, side walls 19 and a rear guide 21. The front and bottom walls are gapped to receive forwarding rollers 26, 27 moving at approximately the same speed as the maximum speed of the feed head. A central throat knife 23 on the front wall co-operates with a supporting roller 24 so that as the lowermost card is advanced it is lifted by the roller 24 into the dotted line position shown and passes under the knife 23. All cards above the lowermost are kept back by the knife. In the form described two feed heads are provided each moving arcuately in gaps 35 in the edges of the bottom wall 17. To the end block 44 of each arm 45 a head block 37 is attached by means of a screw stud 43. The knife 41 is formed on an element 52 attached to the block 37. The centre of the axle 47 is displaced slightly inwardly of a vertical line from the rear edge of the stack. The head is shown in its rearward position, the rear ends of the cards in the stack being supported, when the head is in this position, on the surface 39 of the head. The arms 45 are cam actuated so that the head accelerates from its rearward position of rest and rapidly achieves its maximum velocity. The bottom card is therefore engaged by the knife 41 without impact and moved quickly to the bite between rollers 26, 27. During the feed and return movements of the head, the remainder of the stack is supported on the upper surface 53 of the knife element. The gaps 35 in the bottom wall 17 are kept substantially closed by the block 44 and the feeding head to avoid the possibility of the operator's fingers entering these gaps when replenishing the card stack. The feed head 37 is rotatable on the stud 43 so that the angle of the knife is automatically adjusted to the surface of the lowermost card. This compensates for warped or curled cards.

Title: Improvements in writing instruments
Inventor: BURTON WILLIAM CHARLES CLIFFOR
IPC: B43K29/00
Filed: 1960-04-05
Abstract: 930,464. Writing instruments. ROLL TIP (ENGLAND) Ltd. April 5, 1961 [April 5, 1960], No. 12046/60. Class 146 (3). A retractible writing instrument, e.g. a ballpoint pen, comprises in its projecting mechanism a rotatable member 21 which is rotated step-bystep in response to successive depressions of an operating plunger 17 and has marked thereon around the periphery a series of numbers or characters which upon rotation of the member 21 are brought successively into view through a window 27 in the barrel of the instrument. As shown, the numbers and characters are 1, 2, X and may be used for making random selections in a football pool forecast. The member 21 is rotatably mounted on the rear end of a writing unit 15 and is biased rearwards in the barrel by a spring 24 which grips the writing unit near its rear end. The member 21 has four radially projecting teeth 22 and is of reduced diameter to the rear of the teeth so as to fit rotatably in a bore in the front end of the plunger 17. The plunger 17 is restrained against rotation in the barrel by splines 18 thereon which engage longitudinal grooves in a guide portion 20 mounted in the barrel. Longitudinal ribs in the portion 20 prevent rotation of the member 21 when the writing unit is in retracted position as shown. In order to project the writing unit the operator presses on the plunger 17 and teeth formed at the front end of the plunger, engaging the teeth 22 of the member 21, carry the latter forward until the teeth 22 clear the front ends of the ribs in the portion 20. At this point, owing to co-operating cam surfaces on the teeth the member 21 rotates through # revolution and when pressure on the plunger is subsequently relaxed the spring 24 urges the teeth 22 into engagement with abutments at the forward ends of the ribs whereby the writing unit is latched in projected position. A second depression of the plunger results in a further # revolution of the member 21 which then returns to the position shown wherein the writing unit is retracted. A number or character is visible in the window 27 whether the parts are in their projected or retracted positions. Reference has been directed by the Comptroller to Specification 748,897.

Title: An arrangement for starting induction motors with short-circuited rotors
IPC: H02K7/118
Filed: 1936-04-30
Abstract: 479,115. Motor driving-arrangements. OBERMOSER, K. April 30, 1936, Nos. 12300 and 12301. Convention dates, April 30, 1935 and Feb. 24, 1936. [Class 35] [Also in Groups XXIV and XXXVII] For starting an induction motor with a short-circuited rotor, a clutch is used which does not engage until the occurrence of the jerk imparted to the rotor when the control gear is operated to increase the voltage applied to the motor windings, this controlling operation being delayed by an electromagnet until the current has a predetermined value, the winding of the electromagnet also serving as a choke for initially reducing the motor voltage. In the form shown in Fig. 3, the part 11 of the clutch is carried bv the motor shaft and its central radially extending part has slots to receive pins 12. The pins 12 are carried by bearings in members 3 which move outwards as the speed rises, the pins rolling along the slot edges 14 and finally reaching the position shown, the friction insets 5 on the members 3 then being in engagement with the other clutch part 1. The outward movement of the members 3 is resisted by a common multiturn band spring 10 an end of which is secured to each weight 3 at 9. The pins 12 snap into their positions between the projections 15 when the motor rotor receives a jerk due to the winding connections being changed. The winding connections may be changed by a controller as shown in Fig. 7, one contact 19 of which is brought from the dotted position into engagement with supply contact 26 to initiate the starting process. The windings may then be in star with a choke coil 17 bctween each phase winding and the neutral point, the choke also serving as the winding of electromagnet 18. Another motor winding is connected to terminal 20 which is held in the position shown and connected to choke 17 by a terminal 22 carried by the pivoted core until the current in the choke drops to release the armature 28. Release of the armature permits the left-hand end of core 18 to move downwards, thus disconnecting the choke 17 and enabling the contact 20 to move into contact with terminal 26 and energize the windings at full voltage. A bimetallic strip may be arranged to place an obstruction in the way of the starting lever provided for moving the contact 19 if too frequent starting is attempted. A pilot lamp may be mounted on the tiltable core 18 to indicate its position, there being an appropriate aperture in the starter casing. Specification 307,730, [Class 38 (iii)], is referred to.
