[Also in Division A4] A hair curler includes a plastic body formed by an injection moulding process and comprising annular end members 16, 18 integrally joined by a helical coil 14 and by longitudinally extending members 20, forming the body wall and preferably of serpentine formation to facilitate lateral bending and alterations in cross-sectional area of the body. An elastic retaining member may be mounted in a slit ring 27 in an arm 26 in one of the end rings and in a modification hair-engaging bristles are moulded integral with the coil. A multicavity mould 50 for production of the body by an injection moulding process is shown in Figs. 5 and 6 and has a stationary part 55, attached to the nozzle of a source of heated plastic, and a movable part 56. The part 55 has a runner 64 and sprue 65 for admission of heated plastic to cavities 58 which are surrounded by mould plates 60, 62 formed with longitudinal grooves 68 and end grooves 70, 71, 72, 73. A core 76 slidably received in each cavity has a spiral groove 78 in its surface. After cooling of the plastic the cores are withdrawn by sliding movement of the mould part 56 on shafts 80, 82 bolted on a foundation plate 84, the cores being rotated during withdrawal, on roller bearings 100, by a sprocket chain 102 engaging sprocket wheels 90 and driven by a sprocket wheel 104 on the output shaft 105 of a gear reducer 106 bolted to the movable part 56 which is reciprocated by an hydraulic or electrically operated toggle mechanism 115. The mould plates 60, 62 separate slightly as the cores are withdrawn and knock-out pins (not shown) move outwardly from the mould plate surface to push the body from the mould. In modifications, a sprocket wheel is formed integrally with each core or raok-and-pinion worm and worm-wheel replace the sprocket wheel and chain arrangement.

Title: Improvements in carriage positioning mechanism for typewriters or like machines
IPC: B41J21/06
Filed: 1957-12-23
Abstract: 849,844. Typewriters. ROYAL McBEE CORPORATION. Dec. 23, 1957 [Jan. 17, 1957], No. 39952/57. Class 100(4) Letter-spacing mechanism. A typewriter or like machine including a carriage 4 mounted for letter-spacing and return travel, has a letter-spacing mechanism comprising a primary carriage positioning means for effecting relatively small letter-spaces for differential spacing, tabulating stop means, secondary carriage positioning means, and means operable in response to arresting of the carriage by the tabulating stop means to render the secondary positioning means effective to effect carriage position. This ensures accurate positioning of the carriage after a long run since the secondary positioning means includes a large toothed ratchet wheel attached to the relatively small toothed primary positioning means, and thereby the effects of rebounding are obviated. The primary positioning means for incrimental letter-spacing, comprises a ratchet wheel 45, a radially and arcuately movable spacing pawl 51, a lock pawl 48 and a latch pawl 47. The pawl 51 is moved outwardly when a type key is depressed and it swings quickly clockwise until the pawl nose 51c has traversed a number of teeth on the ratchet dependent upon the length of the letterspace required, and which is arranged automatically by stops 69, 70, 71, 71a operable by the type-keys. Tabulating and Carriage-return mechanism. During a tabulation run or a carriage-return movement the pawl 51 is maintained out of engagement with the small toothed ratchet wheel 45 and an auxiliary pawl 73, forming part of the secondary positioning means, is brought into engagement with the large toothed ratchet wheel 46. Depression of a tabulation key causes a shaft 41, Fig. 2, and arm 42 to rock, and move latch 34 and lever 77. This effects positioning of the tabulating stop means for engagement by a displaced stop 26, Fig. 1, shifts the pawl 51 clear of ratchet 45 and the latch 34 maintains the disengagement. At the end of the run a link 32 releases the latch, and the auxiliary pawl 73 moves into engagement with the ratchet wheel 46. Depression of a carriage-return key rocks a shaft 82 and arm 83, Fig. 6, and rocks lever 77: this pulls on a link 79 and pivots a lever 64 which disengages the pawl 51 and locks it in disengaged position. A latch 75 is also pivoted at the same time to free the auxiliary pawl 75 so that when the left margin stop 9 engages a cushioning lever 11, the lever 64 is returned to normal, and a spring 74 is permitted to rock the pawl 73 into engagement with the ratchet 46. Back-spacing. A separate pawl 84b (Fig. 10, not shown) is moved by a horizontally reciprocable slide to engage the small toothed ratchet wheel 45 and step it in reverse direction.

In Fig. 2 the transducer comprises a forked magnetostrictive element 22, and liquid is supplied to the outer surface of the cylindrical member through a tube 28 connected to a pump 27 and a valve K. In Fig. 4 the transducer comprises piezoelectric elements 8A and 8B and liquid is supplied to the outer surface of the cylindrical member through an annular member mounted on top of the cylindrical member and having circumferentially - spaced axially extending grooves E11 at positions corresponding to nodes in the vibrations on the outer surface of the cylindrical member. In a modification, Figs. 8 to 10 (not shown), the grooves (E21) supply liquid to the inner surface of the cylindrical member; in this case an air stream is preferably passed through the centre of the annula and cylindrical members to accelerate the discharge of the atomised liquid particles. In Figs. 11 and 12 (not shown) liquid is supplied to the outer (Fig. 11) or inner (Fig. 12) surface of the cylindrical member through tubes (E31, E41) leading from the annular member (D3, D4) and in Fig. 13a (not shown) liquid is supplied to the outer surface of the cylindrical member 1 through an elongated member (E511) made of a porous material such as felt, one edge of which abuts against the outer surface of the cylindrical member. Liquid Fuel Combustion Apparatus. Fig. 14 depicts apparatus comprising a fuel guide cylinder 63 in which is mounted the cylindrical member 1 of an atomiser of the invention, a blower cylinder 61 surrounding the fuel guide cylinder, and an ignition heater 66 disposed downstream of the exit opening of the fuel guide cylinder. In operation, liquid fuel is atomized on the cylindrical member 1 and an air stream produced by a blower 62 passes through the fuel guide cylinder, carrying with it the atomized particles which are ignited by the heater 66, supplementary air being supplied through the annular passage 64 between the cylinders. Humidifiers. Fig. 15 depicts a humidifier in which water from a tank 79 is supplied to the cylindrical member 1 of an atomizer of the invention and the atomized particles are conveyed out of the humidifier by means of a stream of air passing through and around the cylindrical member. Atomised particles having a relatively large size fall back into the tank. The apparatus of the invention can alternatively be used for atomizing paint or for atomizing a muddy slurry in a granulator.

Title: Improvements relating to voltage control apparatus for arc welding
Inventor: MORRIS JOHN DENNIS
IPC: G05F1/33
Filed: 1958-12-24
Abstract: 910,680. Automatic arc control. HIRST ELECTRONIC Ltd. Dec. 15, 1959 [Dec. 24, 1958], No. 41686/58. Class 38 (4). In a voltage-control system for a directcurrent arc-welding arrangement a rectifier is connected to an alternating-current supply through a saturable reactor which is designed to drop, before its inductance falls off due to saturation by the welding current, a maximum voltage substantially less than that across the supply terminals. As shown, terminals 14 connected to an arc-welding arrangement are supplied from a secondary of a transformer 10 through a rectifier 12 and a saturable reactor 11. The saturable reactor is arranged to be autoexcited by connecting each load winding 20 in series with a half-wave element 21 of the rectifier as shown. The direct voltage between terminals 14 is maintained substantially constant by energizing a control winding 25 of the reactor by the difference between a datum voltage across a resistor 29 and the terminal voltage. The datum voltage is derived from a secondary of the transformer 10 through a constant-voltage transformer 26, a variable-ratio transformer 27 and a full-wave rectifier 28. When contact is made between the electrodes of the welding arrangement the reactor saturates and drops half to two-thirds of the supply voltage, the remaining voltage being available to build up the welding current so avoiding the electrodes welding together.
