Title: A power-driven machine for use as a kitchen accessory in carrying out mixing, mincing, grating and other operations
IPC: A47J43/06
Filed: 1944-06-09
Abstract: 589,491. Variable-speed gearing. DREVER, R. T. June 9, 1944, No. 11066. [Class 80 (ii)] [Also in Group XXXV] In a motor-gear unit for driving interchangeable devices for domestic and like purposes which are coupled to the output shaft of the unit by pin and socket or equivalent connections the speed of the shaft is adjustable by change-speed gearing, the ratio selected being determined by the means for attaching the driven device. As shown in Fig. 1 the casing 13 contains a motor driving the shaft 15 through the gear train shown in Fig. 2 the shaft 41 of the driven device being coupled to shaft 15 by a pin and slot connection and the fixed part 54 secured to the motor unit by a bayonet type coupling 53, 56. The gear train comprises a pinion 20 rigid with a motor shaft 19 and in constant engagement with gears 21, 22 on arms 23, 24 of a rocker 18 which in the position shown allows the drive of worm wheel 16 on shaft 15 through a worm on the spindle of gear 21, but the rocker can bring gear 22 to mesh with gear 28 which drives shaft 15 through bevels 29, 17. The rocker 18 is moved by a lever 30 which can be operated only when the motor is switched off, and this lever 30 can be connected to a bell crank 58 the lower end 57 of which is engaged by a projection 62 on the fixed part 54 of the driven implement. The bayonet slots 56 on such fixed parts of implements to be driven at high speed extend in the opposite direction to the slots on low speed implements whereby the bell crank lever is moved in the appropriate manner to ensure the correct gear ratio.

Title: Improvements in or relating to electric inspection lamps
IPC: F21L14/00
Filed: 1948-04-22
Abstract: 639,101. Inspection lamps. DULISCOUET, L. April 22, 1948, No. 11086. Convention date, Nov. 18, 1947. [Class 75 (iii) and 75 (iv)] The handle 1a of an electric inspection lamp is approximately at right angles to the axis of the lamp socket 5 and has a flat surface opposite the socket for resting the lamp on a horizontal support. Another flat surface 18 on which the lamp is rested to provide a beam at a small angle above the horizontal is formed on the part 1b of the lamp containing the lamp socket. The lamp can also be suspended by a pivoted wire hook 16 which when not in use is positioned with its transverse part lying in notches 17 in the sides of the handle 1a. The handle is made hollow to provide a chamber for the electric leads and possibly a switch ; access to this chamber may be through the flat surface of the handle. A frusto-conical hood 15 made of elastic material is fitted around the bulb 3 by springing its grooved edge over a flange 13 on the lamp body. The hood may contain a reflector. The lamp socket 5 is mounted on an insulating plate 6 to which is centrally secured a spring-urged contact 7. The body of the lamp is preferably made of a moulded material such as rubber.

Title: Optical information detection system
IPC: G11B7/13
Filed: 1974-03-14
Abstract: 1417374 Data storage INTERNATIONAL BUSINESS MACHINES CORP 14 March 1974 [9 April 1973] 11370/74 Heading G4C [Also in Division H1] Information is stored in a film medium 4, Fig. 1, as a pattern of low and high reflectivity areas 5, 6, 7, and is read out optically by sequential area scanning with a beam from a laser 1, the high reflectivity areas being detected by a change in the operational characteristics of the laser caused by the high intensity of the reflected beam incident on its adjacent resonator mirror R2. The storage medium 4 is an amorphous semi-conductor and may consist of a Te 0.93 - G 0.02 As 0.5  film. In the arrangement shown the laser 1 is a GaAs, GaAlAs or InAs homojunction or heterojunction having its output beam focused on a storage area by lenses 2, 3. The change of operational characteristics is obtained by adjusting the laser pumping power to a value such that it operates below the lasing threshold when directed to a low reflectivity area, but is switched to a lasing state when increased radiation is reflected back to mirror R 2  from a high reflectivity area. A detector, e.g. a PIN diode formed integrally with the laser, identifies the information stored by determining the laser operating state. In an alternative arrangement, Fig. 4, a He-Ne or Hg laser is operationally switched between low and high gain operation, producing infra-red and visible outputs respectively, depending on the reflectivity of the storage area interrogated. To establish this condition the laser must inherently have two competing transitions sharing a common energy level and of distinctly different energy and gain. In the absence of a high reflectivity area 56 in the output beam path, the laser operates in the low gain, infra-red state due to a dichroic resonator mirror 52 which is of low reflectivity at the visible wavelength and of moderate reflectivity in the infra-red, the other mirror 51 being highly reflective. The presence of a high reflectivity area causes the laser to switch to the different wavelength higher gain visible state, the operating state being identified by a frequency detector 59.

Abstract: 201,982. Arnall, T. W., and Short, A. J. April 24, 1922. Lantern panes and panels.-In an illuminated sign or signal for use in street lamps, &c., ribs, corrugations, and like projections are formed on part of the surface so as to throw the light in a particular direction, and other parts of the surface are darkened or obscured. As applied to a hollow red triangle motor signal, the corrugations b, Fig. 1, are on the side toward the light source, and are arranged in six groups, one group at each corner of the triangle at right-angles to the corresponding median of the triangle, and one group at each side parallel to the side. The corrugations b are on the inside, and are preferably of saw tooth section with the steep side towards the light source. The centre part c of the triangle is made opaque, or nearly so, and may be provided with a system of flat or curved mirrors, which may be put in motion, to throw the light falling on such part on the sign. The corrugations b may be circular and concentric with the triangle, and may be separated by spaces of flat glass, or replaced by isolated projections g, h, i, Fig. 7, of conical, pyramidal, or like shape, which may be arranged to form letters or figures. Marginal ribs are formed on the sign, and may be strengthened by wires embedded therein. The Provisional Specification also states that the sides of the triangle may be formed of parallel glass rods, and that the device may be in the form of letters &c. instead of triangular. Reference has been directed by the Comptroller to Specification 3673/85.

Abstract: 800,860. Making bars; welding by pressure; rolling. HUTTENWERKE ILSEDE-PEINE A.G. April 21, 1955 [May 10, 1954; March 2, 1955], No. 11570/55. Classes 83 (2) and 83 (4). In apparatus for joining rolled bars end-to-end, one or more welding devices move in a path about an axis and move over at least part of the path with the ends to be welded and bending devices move with the or each welding device to bend the bars to correspond to at least part of the path. Bars 1, Fig. 1, are fed from the left into a furnace 2, devices 3 push the bars through the furnace, and the bars are ejected by a device 4 to be fed by rollers 5 and grasped by one of the two pressure-welding devices 6, 9 rotating about an axis 7. Bending device 8 rotating with the devices 6, 9 bend the bars and heat-resistant channel 10 extending the length of the arrow 11 prevents heat loss during welding. Welding burrs are removed by milling or grinding apparatus 12 before a device 13 bends the welded bars into wavy form to be advanced through an annealing furnace 15, e.g. gas-heated. Rollers 17 straighten the welded bars before they enter the roll housing 18, a cutter 19 being provided. In one modification the annealing furnace is provided by induction coils. In another modification, in which the welding devices move with the ends of the bars through substantially a complete circle, the welded bars are fed out from the welding devices in the direction of their original feed-in. In a further embodiment two sets of three welding-devices 41, Fig. 4, are provided, rotating on a common axis 49, one above the other, to deal simultaneously with two sets of bars. A path other than a circle may be obtained for the welding devices by' adjusting their radial distance from the axis of rotation. The welding devices may have variable speed drives which are controlled by or control the drive for the bar supply.
