Title: Automatic rice cookers
IPC: H01H37/36
Filed: 1962-02-22
Abstract: 984,438. Thermal switches; electrically tripped switches. TOKYO SHIBAURA DENKI KABUSHIKI KAISHA. Feb. 22, 1962 [Feb. 22, 1961], No. 6942/62. Heading H2B. [Also in Division H5] A temperature controller for a rice cooker with an electric heater 2 provides a continuous heating period until the temperature reaches a first value (130‹ C.) and thereafter thermostatically maintains the temperature near to a second lower value (100‹ C.) for a set period before finally interrupting the heater current. Heating is initiated by raising a two-part lever 18, 19 pivoted freely on a shaft 13 until it is latched by a roller 22, on a spring 29 biased arm 21, engaging a notch 20; a roller 23 then allows a first blade contact 7 to engage a second 6 to energize heater 2. The rice (with water) is heated until it boils dry when the temperature rises sharply to a preset value when the thermal element 31, which consists of a piston moved by a thermally expansible liquid, acts through a lever 11 to separate contact 6 from a further blade contact 5 to interrupt the heater current; the consequently reduced spring bias on contact 5 permits a cam 10 to rotate under a torsion spring 49 so that blade 5 drops back on to surface M lowering the temperature necessary to subsequently open the contacts. During the " off " periods of the heater 2 a high resistance heater 35 connected between contacts 5, 6 gradually expands a liquid in a cylinder 24 driving a rod 36 into engagement with a trip lever 37 to release the roller latch 22. The lever 18 then moves downwards under biasing spring 50, the roller 23 opening the contacts 6, 7 and an abutment 26 on the lever 18 resetting the cam 10.

Title: Improvements in method of forming a hollow fan blade and the apparatus to practice said method
Inventor: LURCOTT WINFRED NORTON

Filed: 1950-08-29
Abstract: 706,076. Making fan blades. WING MANUFACTURING CO., L. J. Aug. 29, 1950, No. 6981/52. Divided out of 706,018. Classes 83 (1) and 83 (2) Making foundry cores; patterns.-A method of making a hollow fan blade comprises forming a pattern of the blade by means of a fixture composed of elements which correspond to the cross-section of the blade and which can be fixed in the required position, making a core and dies from the pattern and then using these to bend and shape a sheet of metal. Assuming that the blade to be formed is of uniform crosssection from the hub to the tip, a pattern 50 of the blade is formed from a number of similar sheet metal sections 14, Fig. 2, each having the shape of the required cross-section and the sections being mounted on a rod 16. The sections are correctly spread by two devices. One of these comprises a fan-like rack 40 formed of uniformly spread ribs 44 pivoted about a pin 46, Fig. 7, and the other comprises two triangular elements 54, 56 mounted in a support 52 so that they are separated by the hub to tip distance of the blade and have angles equal to the angular pitch of the blade at tip and hub. The elements are placed on the rack and the ribs 44 spread so as to contact the undersides of the elements. The surface thus formed by the tops of the ribs is used to give the required spread to the sections 14 by holding the pattern 50 on the surface by hook members 72, 74 engaging the end rib 44 and the ends of the rod 16 as shown in Fig. 1. The sections are then clamped together on the rod 16 and encased in heated wax which is spread to give an even uniform surface. The wax-encased pattern is placed in a moulding box and a material such as plaster of Paris poured in to form mould surfaces from which a core 34 and two dies such as 36 are cast If the blade is to be wider at the base than at the tip, a pattern may be built up as shown in Fig. 5 from sections 15, 17 and 19, spacers 31, a supporting rod 25 and a supporting V-shaped strip 29, the sections being relatively positioned as by using the rack 40. Specification 706,018 is referred to.

Abstract: 852,617. Equalising -load on wheels. ABJORN ANDERSON A.B. March 2, 1959, No. 7207/59. Class 108(2). A tractor body 1, Fig. 1, is supported on wheels 6, 7 which are attached to a bogie 5, by trunnions 4. A pair of hydraulic jacks 8, also support the tractor body. Each jack consists of a double acting cylinder, the upper and lower chambers of which are connected with the corresponding chambers of the jack on the opposite side of the tractor. This interconnection serves to equalize the weight distribution on the four wheels. If the left hand front wheel moves upwardly, the right hand front wheel will move a corresponding distance downwardly, thus the body of the tractor is displaced by a smaller amount than the wheels. In order to eliminate entirely vertical movements of the body, or to enable the height of the body to be adjusted, a reservoir of hydraulic liquid, a pump, valves and conduits are provided so that liquid may be supplied to or withdrawn from the hydraulic jacks to raise or lower the level of the tractor above the ground. A single hydraulic jack 33, 34, Fig. 5, may be used at the rear of the tractor. One end of the jack is pivoted' at 35 to the tractor body, whilst the opposite end is attached to bogie-beams 40 through links 36, 38. A single hydraulic jack 60, 61, Fig. 7, located half-way along the tractor body and connected to bogiebeams 52 through linkages 58 and 54 may be provided. The linkages 58 are attached to the tractor body by a member 57. The tractor body may be raised or lowered with respect to the ground in the two latter embodiments as in the embodiment first described.

Abstract: 331,813. Bingham, G. C., and Bingham, R. March 6, 1929, No Patent granted (Sealing fee not paid). Dressing poultry.-A machine for plucking poultry comprises an endless s rotatable flexible member in one or more parts, which is deflected to cause gripping surfaces thereon to open and close at predetermined intervals during each rotation. As shown in Fig. 3, a belt D is trained over pulleys B, B<1> having peripheries shaped to distort the belt and bring together members d thereon to grip the feathers, and to separate the members to release them. The pulleys are contained in a casing from which the feathers are, expelled by a rotary fan. In Fig. 6, the arrangement is made more compact by forming the pulleys B, B<1> from a number of discs which are interdigitated. In a modification, two belts, preferably of laminated steel, are trained over pulleys, and studs projecting inwardly from the belts engage cam grooves in the pulleys which cause the belts to move towards or away from one another, the feathers being gripped between the belts. Figs. 9 and 10 show a construction in which the grippers D are connected together but are mounted on separate belts. The belts may, however, be unconnected and retained on the pulleys by side flanges. In a further modification, inclined rollers are engaged first with the upper runs of two belts and then with the lower runs to cause them to advance and recede.

Abstract: 137,801. Bijur Motor Appliance Co., (Assignees of Bijur, J.). Jan. 16, 1919, [Convention date]. Turning-gear. - An electric starting-motor 1 drives a starting-pinion 28 through reduction gearing 10, 7, a drum 14 keyed at 13 to the gear 7, and a shaft 16 on which is mounted a disk 18 keyed to the drum 14 at the end more remote from the driving-connexion 10, 7 with the starting-motor. A flanged nut 36 engages a screwthread 26 on the shaft 16 and has lugs engaging slots 38 in a barrel 33 integral with the pinion 28, a heavy spring 43 being interposed between the nut and a shoulder in the barrel. The parts are retained in place by annular screw caps 23, 40, a screw ring 14<1>, and a nut 17, and the pinion 28 slides within the neck 44 of the drum 14 and over the end 27 of the shaft 16. The screw-andnut connexion 26, 36 effects the automatic axial ruovement of the pinion 28 into gear with an engine member 29, this movement being limited by shoulders 49, 39. The slots 38 allow relative movement of the nut 36 and the barrel 33 if the gear teeth meet end to end, and also when the engine goes over compression points. A light spring 47 prevents the pinion 28 from creeping into engagement with the gear 29 when the engine is running. The end members 2, 3 of the motor are provided with lugs 4, 5 for mounting on the engine crank-case, and the gases 7, 10 are enclosed by a plate 11.
