Title: Improved gear mechanism suitable for use as a pump, compressor or motor
IPC: F04C2/107
Filed: 1946-09-10
Abstract: 679,163. Rotary engines and pumps. SOC D' EXPLOITATION DES BREVETS MOINEAU. Sept. 10, 1946 [Sept. 13, 1945], No. 27181/46. Class 110(ii) A rotary mechanism comprises two groups of gears with parallel axes, each formed of an element 2 rolling within another, 1 or 3, the two elements 2 being rigidly connected together by a shaft 5. One stator 1 is fixed and the other 3 given a gyratory movement around the line passing through the axis of the gear 1. The latter motion is secured by a crank 8 on a shaft 7. Flexible diaphragms 10, 11 allow the movement and provide seals. The pitches of the helicoidal elements are of opposite hand. In the case of a pump fluid enters an inlet 12, passes through the annulus between the shaft 5 and a tube 9, is pumped by the element 4 and forced through the shaft 5 to the pump 2 which delivers to a port 13. In cross-section each rotor has two lobes and each stator three lobes. The crank 8 is balanced. Two or more pumps or engines may be combined. Fig. 6 shows another arrangement where four pumps, two being in a plane perpendicular to the figure are driven by screw mechanisms E. Outer elements 3, of the four gears E, are driven in a circular movement by a crankshaft 7. A header 14 supplies all four pumps and the pumps discharge into a header 15.

Title: Electrical control system for oven programmer
IPC: G05B19/10

Abstract: 976, 797. Automatic temperature control systems. KING-SEELEY THERMOS CO. July 10, 1963 [July 25, 1962], No. 27286/63. Heading G3R. A temperature control system for an electric or gas oven is provided with a number of resistor circuits 138... 143 which may be selectively connected to the oven temperature sensitive resistor 132 through switches 144... 149 operable by moving a selector knob 10 from an OFF position 16 to the corresponding one of a number of positions 18... 34, this movement causing a corresponding set of printed information to appear in a window 35 which information, in certain knob positions, includes instructions relating to additional action required from the operator to complete a particular programme cycle. Movement of the knob 10 to the various positions produces the following operating conditions:- Position 18. The oven temperature is manually set by adjustment of resistor 160 through the knob 12. Positions 20, 22. The temperature is set at a high or low value respectively by fixed resistors 139,140. Position 24. Resistor 141 sets an upper temperature limit and the oven temperature is varied by a conventional meat probe unit whose jack is inserted in the circuit position 130 in series with the oven heat control 125. Position 26. The temperature is fixed by resistor 142 and switch 202 is closed to drive a "Roto Grill" motor. Position 28. The temperature is set by adjustment of resistor 160 and the cooking time is controlled by the setting of a conventional automatic clock 170. Positions 30, 32. As for position 28 but the oven temperature is maintained at one or other of two temperatures after the clock terminates the cooking period until knob 10 is turned off, these temperatures being determined by resistors 186, 188. Position 34. As for position 32 but, prior to the cooking period determined by the clock 170, the oven is warmed to a temperature determined by the resistor 140. The energization of the heat control device 125 is controlled by a bimetallic switch 100 having a switching leg 104 and a leg 102 compensating for ambient temperature and line voltage variations. The legs 102,104 have balancing, control and feedback windings 106,108,128 connected as shown, and the switch 100 may be arranged to pulse with an on/off ratio controlled by the combined resistance of the resistor 132 and associated series resistance, or it may operate on a thermostatic basis by reducing the effectiveness of the winding 128 so that contacts 114, 116 are operated by a change of resistance in resistor 132.

An arm 24 fixed to a rotatable spindle 13 carries a reference mark 25 and a pillar 27 adjustably supporting a slidable housing 28. A block 30 slidably mounted within 28 for movement in a direction tangential to a circle coaxial with the spindle 13, may be adjusted and held in position by screws 31, 32, and supports a probe 33 having a pivoted or cranked tip 34. The probe is connected to an electrically actuated recorder 35 geared to the spindle 13 and provided with graph paper 37, and adjustable base projections either side of the zero mark on the scale 26 coact with a switch (not shown) on the underside of the arm and cause the stylus to record start and finish lines on the paper 37. The probe 33 and the recorder stylus may first be adjusted or zeroed by locating a setting bar 40, Fig. 2 in the position intended for the gear to be tested and arranging for the probe tip 34 to contact the bar 40 at various datum positions corresponding to the dimensions of the gear to be tested. The bar is then replaced by the test gear and the arm 24 and spindle 13 rotated to move the probe in a small circular arc over the tooth flank to produce a graph on the recorder 35. In a modification the probe may be rotated through 180 degrees and displaced laterally through a distance equal to twice the radius of curvature of the tooth flank in order that both flanks of a tooth can be tested without inverting the gear. In a further modification the gear is mounted on the arm 24 and the probe 33 on the table 10.

Abstract: 659,718. Fishing tackle. MAYER, J. Nov. 2, 1949, No. 28106. [Class 48] A fishing line is cast by compressible resilient means arranged to act on the float or sinker, releasable means being provided to hold the resilient means in compressed condition. A float 11 slidably fitted in an extension 2<1> of the barrel 2 of an apparatus resembling a rifle abuts a tube 6 urged outwardly by a helical compression spring 25 acting between a ring 27 fixed to the barrel 2 and a ring 26 fixed to the tube 6. The spring is held compressed by a pivoted pawl 15 urged by a spring 17 to engage the serrated edge of a tongue 13 formed on a collar 12 on the tube 6 and the spring is released to project the float out of the extension 2' by a trigger 24 connected by a link 22 to a pivoted cranked lever 18 having a slot 29 engaged with a pin 20 on the pawl 15. To compress the spring a lever arm 35 pivoted to a short arm 37 pivoted on a pin 38 is swung downwardly through a slot in the casing 41 and thereafter oscillated so that the serrated tongue 13 is pushed backwardly by a tooth 35<1> on the arm 35; a spring acts on the free end of the short arm 37 to force the tooth 35<1> into engagement with the serrated tongue 13. The fishing line 4 extends from a reel 3 mounted between the barrel 2 and the stock 1 through the tube 6 and is attached to a link 7 secured by a light spring 9 in a bore 10 in the float 11. A hook 8 is disposed in the float bore 10 and is connected to the link by a length of coiled line 4' which unwinds when the float lands on the water. The reel 3, Fig. 4, is mounted on the coneshaped ends of two bearing shafts 5 on one of, which a pinion 32 is slidably mounted. A spring 34 urges the pinion into engagement, either frictional or toothed, with the reel and at casting disengagement is effected by a lever 33. The pinion meshes with a gear wheel 31 on a manually rotated shaft 30. A safety catch 28 for the firing mechanism engages a depression in the collar 12. A removable cover on the casing 41 enables the parts to be examined.

Title: Improvements in or relating to apparatus for taking photographs of cavities of the human body
IPC: G03B17/48
Filed: 1947-10-21
Abstract: Relates to a device for attaching a surgical instrument including a telescope and an electric lamp for illuminating the field of view of the telescope to a photographic camera having a shutter actuator. The device comprises a housing adapted to be carried by the camera, and provided with means for removably connecting the camera to the eyepiece of the telescope so that the objective lens of the camera is positioned to receive light emanating from the telescope, and means carried by the housing and operable by the camera shutter actuator for increasing the voltage across the electric lamp.  The lamp voltage may be increased by short-circuiting a resistance in the lamp circuit, as by a pivoted contact member movable by the shutter actuator.  A mirror may be placed in front of the camera lens to reflect light into an auxiliary eyepiece, and mounted to be swung aside by the shutter actuator just before exposure.  Such movement of the mirror may also short-circuit the resistance.
