Title: Improvements in washing machines
IPC: D06F13/04
Filed: 1930-07-11
Abstract: 359,015. Centrifugal extractors. KIRBY, J. B., R.F.D. No. 16, Everett, Ohio, U.S.A. July 11, 1930, No. 21088. [Class 23.] In a combined washing and drying machine wherein the washing is effected by the axial reciprocation of a pounder 110, Fig. 1, within a perforated clothes container 91, the shaft 46 of the pounder being coaxial with the container, and wherein the drying is effected by the rotation of the container at high speed after the reciprocation of the pounder has been stopped and the container raised within the stationary casing 73 to the position shown in Fig. 3, a pedal 22 controls the drive to the pounder and the vertical and rotary movements of the container. The shaft 46, Fig. 1, moves freely in a sleeve 40 secured in the bottom 2 of the stationary casing and the lower end of the shaft is carried in a stirrup 49, Fig. 8, having upstanding ears which are pivoted at 50 to links 51, Fig. 1, the lower ends of which are pivoted to a lever 32. A disc 53, Fig. 8, having axially projecting teeth 54 is pinned to the shaft 46. The lever 32, Fig. 1, is rotatable about a pin 30 which extends between the limbs 21 of the bifurcated pedal 22 which is pivoted about another pin 20. The arms 35 of a bifurcated lever 36 are carried upon a pin 34 carried by the hub of the lever 32 and arranged transversely to the pin 30, and the upper end of the lever 36 is ball-and-socket jointed to a crank arm 13 carried by a hub 11 rotatable about a stud 10. A motor 125 drives a friction disc 65 through a belt 68 and the disc drives a wheel 42 of which the hub 41 is slidably mounted upon the sleeve 40. In the lowest position of the hub 41 as shown a pinion 44 thereon engages a gear wheel 12 on the hub 11, whereby the shaft 46 is axially reciprocated. When the pedal 22 is depressed the stirrup 49 is raised to a point higher than its normal maximum height during axial reciprocation and at which the clutch teeth 54 of the disc 53 engage axially projecting teeth 45, Fig. 8, of an enlargement of the hub 41, thereby raising the hub to disconnect the drive between the gears 44, 12 and so stopping the reciprocation of the pounder. The raising of the hub 41 also moves the friction wheel 42 nearer to the periphery of the disc 65 whereby the hub 41 is rotated at a greater speed. The rotation of the hub is then transmitted to the shaft 46 through the teeth 45, 54. The operator depresses the plunger before depressing the pedal whereby the upward movement of the clothes container is started by the normal motor-actuated motion of the lever 32, the final upward movement and the disconnection of the gears 44, 12, being effected by the depression of the pedal 22. Buoyant pivoted splash guards 1411, Fig. 3, become operative during the extracting operation.

IPC: B62D55/116
Filed: 1937-08-04
Abstract: 577,274. Armoured vehicles. TAPP, E. T. J. Aug. 4, 1937, No. 21502. [Class 92 (i)] [Also in Group XXXI] A power-driven armoured vehicle 1 is provided with a shallow armoured compartment 14 which accommodates one or more persons and which can be elevated bodily with respect to the vehicle frame to increase the field of vision of the occupants when directing gun fire or when the vehicle is passing through water. In the form shown, the armoured compartment 14 is normally housed between the side frame members 7 of an endless-track vehicle and is capable of being elevated about trunnions 16. The occupant is accommodated in a prone position and is provided with hand and foot controls for the propelling engine 2 and with means for elevating the compartment and manipulating a swivelling machine gun turret 34 at the forward end of the compartment. The propelling internal-combustion engine 2 is enclosed in a casing 12 and drives the differential axle 4 for the endless-track sprockets 5. The elevation of the compartment 14 is effected by a vacuumoperated spring-pressed piston 20 in a cylinder 19, the piston being anchored by a chain 23 to a spring buffer 26. The space above the piston 20 is connected to the inlet manifold of the engine 2' by a pipe 74 having a control valve 76 which is operated by the occupant to apply a vacuum to effect the elevation which is assisted by a spring 21 on the other side of the piston. Air pressure or hydraulic means may be used in place of the vacuum means. The gun turret 34 swivels on the end of the compartment being counterbalanced by a weight 35. The gun 40 with hemispherical shield 39 is mounted in a traversing support 37. The occupant controls the vehicle drive by pedals 54, Fig. 4, on a shaft 51 which, to control the steering, is rocked bodily in a lateral direction about either of the pivots 52 to operate Bowden cables 55 leading to the levers 56 of the brake drums of the driving sprockets 5 of the endlesstracks. The pedals are also movable round the axis of the shaft 51 to operate Bowden cables 57, one of which actuates the engine throttle and the other the engine clutch. A third pedal 58 on a shaft 59 is provided for braking by operating the cables 55 simultaneously. Gear change is effected by a handle and cables. The air intake for the engine carburetter 63 is through the hollow trunnions by pipes 15, 65 leading to the top end of the compartment 14. The engine exhaust is through extractors 67 which normally promote the flow of cooling air over the engine casing, but, when the vehicle is passing through water, a pressure of gas is built up to exclude water. To guard against the entrance of poison gas, a blower 68 supplies filtered air under pressure to the compartment. In a modification, provision is made for traversing the compartment on a vertical pivot on the vehicle chassis.

Title: Improvements in thread chasing mechanism for automatic lathes
IPC: B23B11/00
Filed: 1936-08-05
Abstract: 479,493. Automatic thread-cutting. FAIRWEATHER, H. G. C. (National Acme Co.) Aug. 5, 1936, No. 21.589. [Class 83 (iii)] Thread-cutting mechanism for an automatic lathe comprises a vertically and horizontally movable slide arrangement carrying a cutter, a pattern carrying clutch-controlled shaft, means for rotating it, means operated by the slide arrangement for controlling the clutch, an axially movable oscillating shaft, means operated thereby for horizontally shifting the slide arrangement, means carried by the oscillating shaft and co-operating with the pattern of the pattern-carrying shaft for axially moving said oscillating shaft, and means for oscillating said shaft at a predetermined time. The cutter 4, Fig. 1 (elevation) is carried on a vertical slide 2 arranged on a horizontal slide 1 which is mounted on a main vertical slide S moved bv the usual machine cam shaft. An inclined edge 23 on the slide S engages a horizontal rod 24 and serves through the lever 25 to close a friction clutch 6 and thus start the thread cutting motions. The driving shaft 20 rotates at the same speed as the work spindle of the machine, but the gearing 21 is adapted to rotate the shaft 6 at only half this speed so that the pattern or lead screw 7 is provided with a thread pitch twice the value of that to be cut. This lead screw may be replaced by others of a different pitch and the wheels 8, 9, 10 may be changed to vary the driving ratio of a cam 11, adjustably fastened to the wheel 10, when it is desired to cut threads of more than one start. The cam 11 is adapted to engage, in the retracted position of the thread cutting tool, a lever 13 the movement of which is transmitted to the nut-part 15a, Fig. 4, through a cushioning spring 33. A lever 14 is at the same time rotated to bring its spring pressed end 14a into contact with a ledge 14b thus retaining the nut-part in engagement with the leadscrew as the former is moved along. The horizontal movement thus obtained is transmitted through a tie-bar 16 to a rod 18 coupled to the horizontal slide 1. This movement continues until the nut-part falls out of engagement with the screw by the part 14b reaching the end of the ledge 14a or positively by an abutment 15d and roller 15c Fig. 2, the parts being then returned to the initial position by a compression spring 37 surrounding the rod 18. Relief of the cutter prior to the return of the horizontal slide for the start of another cut is obtained through a cam 35, Fig. 1, which engages with the face 34 of the vertically movable tool carrying slide and releases the latter, pressed upwardly by springs 36, a sufficient distance to clear the cut threads when the reduced. part of the cam comes into operation. This slide is positively moved downwards by a lever 42 engaging a cam surface 41 for the start of another threadcutting operation. An' adjustable screw stop 43 limits the downward movement of the main slide S.

Title: Improvement in Electric Welding.
Inventor: MURRAY THOMAS EDWARD
IPC: B23K11/31
Filed: 1918-12-24
Abstract: 121,956. Murray, T. E. Oct. 4, 1917, [Convention date]. Heating by electricity.-Metal sheets &c. are united by electric welding by a process in which the sheets are heated by passing currents through each sheet in a direction parallel to the faces to be joined and, when the metal is plastic, pressure is applied over one or more definite areas as in spot welding. As shown in Fig. 2, sheets 7, 8 to be joined are normally separated slightly from each other, or they may rest in contact, and the sheet 8 is supported on electrodes 3, 4 which receive current from one transformer, and upon the sheet 7 are placed electrodes 5, 6 which receive current from a second transformer. The electrodes 3, 4, rest on an insulating base 1, with a central boss 2 upon which the heated metal between the electrodes is pressed by a vertically movable tool 10. In modifications, one electric circuit may supply the upper and lower electrodes, Fig. 4, and two pressing tools 10, 20 may be used. The pressing tool 10 may be of a size nearly equal to the space between the electrodes 5, 6 and 3, 4. or it may be considerably smaller, and three pairs of electrodes 14, 15; 16, 17; 18, 19 may be used as shown in Figs. 9 and 11, and two sets of pressing arrangements used. The current flows from the middle set outwards and the middle electrodes 14, 15 may be large as shown in Fig. 9, or small as shown in Fig. 11.

Title: System for energizing electrical precipitators and the like
Inventor: WILLISON RALPH EUGENE
IPC: B03C3/68
Filed: 1952-08-28
Abstract: 723,058. Automatic control systems for electrostatic precipitators. RESEARCH CORPORATION. Aug. 28, 1952, No. 21648/52. Class 38 (4). In order to control the voltage applied to the electrodes of an electrostatic precipitator at such a value that some 50 to 100 inter-electrode sparks occur per minute, a ratchet-wheel is rotated one tooth on the occurrence of each spark, and the rate of rotation of this wheel is compared with that of a motor running at a reference speed, any error operating a relay controlling a reversible motor actuating a voltage regulator. The precipitator 10 is supplied from an adjustably tapped autotransformer 16, high voltage transformer 20 and rectifier 23. Sparking is detected by a capacitatively coupled probe 27 which causes a thyratron 28 to fire on the occurrence of a spark. This discharges a condenser 39, which recharges from a condenser 40 and source 43, thereby energizing solenoid 45 to rotate ratchetwheel 47. The speed of this wheel is compared with that of a motor 55 in any one of three ways. As shown, a mechanical differential 53 is driven by the two inputs, and the output controls a cam 63 actuating contacts 78 or 82 to control the reversible motor 69 which adjusts the tapping on transformer 16. A manual switch 83 is used to make initial adjustments. Additional cams, Fig. 2 (not shown), interrupt the two inputs to the differential if the cam 63 rotates too far due to a fault. In a second embodiment, Fig. 3 (not shown), an electrical differential comprises a Selsyn having a single-phase winding rotated by the reference motor, and a two-phase winding rotated by the ratchet, the output voltage of the latter controlling a thyratron controlling the motor relay. In the third embodiment, Fig. 4 (not shown), the differential consists of a circular potentiometer, the track of which is rotated by the reference motor, whilst the slider is rotated by the ratchet wheel. The voltage tapped off the potentiometer controls the motor relay.

Title: Production of phenylene diacetic acids
Inventor: MCLEAN ANDREW
IPC: C07C49/76
Filed: 1955-07-28
Abstract: Phenylene diacetic acids are made by alkylating benzene with normal butenes to form disecondarybutylbenzene, oxidizing the latterwith molecular oxygen, reacting the di-acetylbenzene so formed at elevated temperature with aqueous ammonium polysulphide or with sulphur and a dry amine or ammonia to form phenylene diacetic acid diamide or di-thioamide, followed by hydrolysis to phenylene di-acetic acid. The alkylation may be conducted with a mixture of butene-1 and butene-2 containing up to 5 per cent of isobutene, and which may contain recycled mono-sec.-butyl-benzene, in the presence of sulphuric acid, aluminium chloride or hydrofluoric acid at temperatures of up to 30 DEG  C. to give a mixture of o-, m- and p-di-sec.-butylbenzenes.  The oxidation may be effected at 100-150 DEG  C. in the presence of salts of cobalt or manganese such as cobalt isononanoate.  Acetaldehyde and ethanol may be recovered from the effluent gas from the oxidation reactor.  Individual diacetylbenzene isomers may be recovered from the oxidate so obtained (i) by distillation to remove unchanged di-sec.-butylbenzene, butyl acetophenone and butyl butenylbenzene which may be recycled or further oxidized separately and leaving a residue from which p-diacetylbenzene crystallizes, the mother liquors giving the o- and m-isomers on distillation; or (ii) by diluting the oxidate with ether to precipitate the p-isomer and distilling the filtrate to recover the other isomers and by-products.  The individual or mixed diacetylbenzenes may be heated with the ammonium polysulphide to temperatures up to 200 DEG  C. in a closed system and optionally in the presence of ethanol, dioxane or pyridine as solvents to give the diamide, or with sulphur and anhydrous ammonia or methylamine, dimethylamine, morpholine or piperidine at 140-160 DEG  C. under pressure and in the presence of a solvent such as ethanol to give the corresponding thio-amide.  The amide or thioamide are hydrolysed with aqueous or ethanolic alkali or a mineral acid.  An example is given.
