Title: Improvements relating to vegetable cutters
IPC: B26D1/29
Filed: 1929-06-27
Abstract: 329,212. Wilson, W. F. June 27, 1929. Cutting vegetables.-A macline of the type in which vegetables pass down a hopper to a rotary cutter at the base has the hopper 4 subdivided by a diametral fin 7 extending from top to bottom of the hopper, a plunger 10 to press the vegetables down on the cutter being made in halves arranged one on each side of the fin. The halves of the plunger are carried by vertical rods 11 guided in a vertical bracket 12 and actuated through links 14 connected to pivoted levers 15 by a handle 17. The plungers may be retracted from the hopper and swung clear thereof to permit the hopper to be charged. The hopper itself is pivotally mounted on the frame so that it can be moved sideways to permit the knife to be altered on the cutter. Switches automatically cut off the current to the cutter driving motor 3 when either the hopper is being charged or the knife changed.

Patent GB-295683-A (GB)
Title: Improvements in temperature-indicating devices
IPC: G01K5/32
Filed: 1928-07-09
Abstract: 295,683. A. C. Spark Plug Co., (Assignees of Smith, F. D.). Aug. 17, 1927, [Convention date.]. Thermometers.-In a cooling-water system for an internal-combustion engine in which the flow of water is thermostatically controlled, the thermostatic element is connected to a pressure gauge on the dashboard of the vehicle so as to indicate the temperature of the water. The thermostatic element comprises a resilient chamber 26 containing a liquid such as ether and situated in a container 22 between the water conduit 20 and the radiator 12. A stem 36 connects one end of the chamber 26 to a valve 38 which closes the end of the container 22 and prevents the circulation of water until the temperature has risen sufficiently for the valve to be lifted from its seat as a result of the expansion of the chamber 26. A fiange 24 forms a stop to limit the expansion of the chamber. At its other end the element 26 is connected by a tube 52 to a pressure-operated indicator 54 which is mounted on the dashboard and is marked to show the temperature of the water. This indicator is operated by the increase in pressure which results from a rise of temperature after the further expansion of the chamber 26 has been prevented by the flange 24. The indicator is also marked to show whether the valve 38 is open or closed. The chamber is filled at less than atmospheric pressure so that should it become broken the consequent use of pressure within the chamber will move the valve off its seat and will also move the indicator to give warning of defective conditions.

The formation of the tabs provides apertures 55 in end shield 16 for the passage of cooling air drawn through the motor by fan blades 60 on the rotor. Plate 32 has a toothed periphery co-operating with the permanent magnet core 62 of a coil 61 which produces a signal proportional to the speed of the plate and which is used to control the energization of the clutch. Bearing 18 is lubricated by felt wicks 27, 28 contained in cups 28, 30 pressed on to end shield 15.

Abstract: 772,056. Switches, partly electromagnetic thermal switches. GENERAL ELECTRIC CO., Ltd: July 11, 1955 [July 9, 1954], No. 20203/54. Class 38(5) A switch intended for overload protection comprises a load-current-carrying bimetal strip 2 and a temperature-compensation bimetal strip 1 supporting, respectively, contacts 4, 3 which are normally in engagement to energize the load, the strip 1 being insulated from the strip 2.

Title: Improvements in hydraulic turbines
IPC: F03B11/02
Filed: 1919-08-18
Abstract: 140,004. Taylor, H. B. Aug. 18, 1919. Combined-flow type; casings; working-fluid supply.-An inward-flow hydraulic turbine comprises a rotor 31, Fig. 1, surrounded by a volute inlet chamber 39 formed in the concrete structure 37. The rotor is mounted in bearings formed in a cover-plate 35 situated at the lower end of the metal-lined pit 36. The rotor is surrounded bv cast-iron directing-vanes 40, mounted in rings 41, 42. The water on leaving the rotor blades drops on to a cone 46 and passes through diffusion vanes 49 to a volute exhaust chamber 48. The vanes 49 are mounted in rings 50, 51. The vanes 40, 49 and rings 41, 42, 50, 51 act as supports for the concrete structure 37 and the rotor 31. Adjustable guide-vanes 44 are pivotally mounted in the head-cover 35. The rings 50, 51, 41, 42 may be made integrally or built-up in sections. In a modification, the diffusion vanes 52, Fig. 4, are cast integrally with a cone 54 which caps the part 46 of the concrete structure, and are secured at their outer ends to a ring 53. In a further modification, instead of the water being discharged in a single spiral or volute chamber it is gathered in two opposite spiral chambers 55. Fig. 7. In a further modification, the turbine 31 and diffusion vanes 52, Fig. 8, are situated at opposite ends of a flaring draft-tube 56, whilst the discharge chamber 57 is semi-circular instead of volute-shaped. The draft-tube 56 may be metallined. In a further modification, Fig. 17, there are two sets of diffusion vanes 67, 69 leading to two annular chambers 63, 64. The central stayring 71 co-operates with an annular partition 72 carried by the rotor to separate the water into two distinct streams. In a further modification, the chambers 63, 64 are replaced by a single chamber. Specification 123,132 is referred to.

Title: Illumination apparatus
IPC: H05B41/40
Filed: 1974-05-08
Abstract: 1454962 Supply circuits for discharge lamps BERKEY PHOTO Inc 8 May 1974 [10 Sept 1973] 20335/74 Heading H2H Illumination apparatus comprises one or more discharge lamps L1-L4, power input means connectible to an alternating power source P1, a voltage varying transformer T1 the output voltage of which may be set within a range which causes the or each discharge lamp to exhibit a positive impedance characteristic and circuit means for connecting the output voltage directly across the lamp or lamps, the input means, the voltage varying transformer and the circuit means being arranged to exhibit an impedance in series with the lamp or lamps substantially less than the positive impedance of the lamp or lamps. The lamps may be xenon filled quartz tubes and the primary winding W1, the secondary winding W2 and the starter winding W3 of the transformer are connected in series as an auto transformer. The output voltage of the transformer is set to a suitable value at a tap T0 by depressing a selected push button PB of a switch S2 to close one of the contacts CN, the movement of the push button initially opening contacts CC to de-energize a relay K1. Contacts K1.1, K1.2 of the relay open to prevent arcing across the contacts CN and then the pushbutton allows the contacts CC to reclose. A timer TM enables a relay K2 to be energized after a period of five seconds whereupon contacts K2.1 close. Bidirectional switches Q1, Q2 break down when the voltage in each half cycle reaches a predetermined value to supply high frequency pulses to the primary windings of transformers TS1, TS2. The secondary windings supply the pulses to the lamps to start the discharge and the voltage at the tap T0 drives the lamps into an arc discharge exhibiting a positive impedance. Air blowers B cool the lamps and a volt meter M measures the voltage at the tap T0. If this voltage is outside the desired range it is adjusted by depressing the push buttons of the switch S2.
