Title: Improvements in or relating to driving mechanisms for use with toys
IPC: F16H37/00
Filed: 1959-12-30
Abstract: 905,392. Mechanical toys. BOEHME, G., [trading as MARKE & CO. KOMM.-GES.]. Dec. 30, 1959 [Feb. 20, 1959], No. 44220/59. Class 132 (3). [Also in Group XXIV] A mechanism for driving a toy comprises a pair of driven shafts each connected to its load through an irreversible worm-and-pinion gearing, a toothed wheel mounted on each driven shaft and driving means adapted for selective engagement in the teeth of the two toothed wheels according to the direction of rotation of a driving shaft. As shown, a reversible electric motor 1 drives through a gear 3 to two gears 6a, 6b freely rotatable upon shafts 4a, 4b separately rotated to perform different operations in the toy, each gear 6a &c. carrying a pawl 7a which in one direction of rotation engages with a ratchet-wheel 5a secured to the associated shaft, the pawls and ratchet-wheels being oppositely directed so that when the motor drives in one direction, one pawl and ratchetwheel overruns while the other transmits drive to its shaft, while when the motor rotates in the opposite direction, the first pawl and ratchet overruns while the second now transmits drive. The two shafts each drive through an irreversible worm-and-pinion gearing (not shown) to their respective loads. As a modification, the pawls and ratchets 5a, 7a are dispensed with and the motor 1 is mounted to one side, the gear 3 meshing an idler gear rotating at the end of a lever turning about the axis of the motor shaft 2. Depending upon the direction in which the motor 1 drives, the idler gear meshes either with the gear 6a or with the gear 6b. A second motor with a further two driven shafts geared thereto according to the invention may be incorporated into the toy.

Title: Method and means using infrared radiation for assessing the amount of a component in a substance
IPC: G01J3/42
Filed: 1976-10-27
Abstract: 1527684 Determining the amount of a component in a substance INSINOORITOIMISTO INNOTEC OY 27 Oct 1976 [30 Oct 1975] 44692/76 Heading G1A In a device for determining the amount of a component (oil) in a substance (water), the mixture is directed from a conduit 14 into two conduits 11 and 16. One conduit 16 is preceded by a filter 15. Thus a sample fluid-flow and a reference fluidflow is alternately directed by a pump 12 via checkvalves 18 into a sample cuvette 13. Infrared radiation from a source 21 passes as shown via a limiting stop 22, the cuvette 13 and a filter 25 to a detector 24. The detector's output is integrated in synchronism with the pump by an integrator 31. This determines the difference in absorbtion between the sample and the reference which indicates the amount of component (oil) present in the substance (water).

IPC: F04B53/16
Filed: 1969-09-12
Abstract: 1,272,467. Reciprocating pumps. MODINE Ltd. Sept.14, 1970 [Sept.12, 1969], No.45103/69. Heading F1A. A pump for dispensing measured quantities of beer comprises coaxial cylinders 10, 11 with pistons 15, 16 connected by a rod 17, pumping chambers being defined between the inner faces of the pistons and a partition 12, and actuating chambers between the outer faces and end covers 14. The pumping chamber stroke volume, e.g. half a pint, is set by adjustable stops 19 which are locked by wiring and sealing to tie rods 13, Fig. 4 (not shown). Compressed air is admitted alternately to the actuating chambers by a valve 44a controlled by a two-position manual valve 52 which connects the air supply line 49 to either side of valve 44a for movement of pistons 15, 16 to the left or right, line 49 being connected to valve 44a at 45. On movement of the pistons, the pressure from the exhausting actuating chambers acts via valve 44a on a diaphragm 47 which opens a shutoff valve 55 to connect air supply line 49 to a differential piston valve 50a in the supply line to manual valve 52, thereby moving valve 50a to cut-off the supply to valve 52, preventing interference by the operator with the dispensing stroke, once initiated. At the end of the dispensing stroke, a bleed orifice in the diaphragm housing slowly vents the exhaust pressure to close valve 55 in a time slightly longer than that taken for the dispensing stroke, valve 50a then restoring the air supply to valve 52 ready for the next cycle. A slide valve 28, Fig.2 (not shown), controlled by valve 52 changes over the pumping chamber connections 20, 21 between beer supply line 25 and discharge line 38. A sensitive non-return valve 60 adjacent dispensing nozzle 39 prevents beer in the system from going flat. Each piston 15, 16 has a cruciform sealing ring 22 and a cup-leather 23.

Abstract: 1,247,880. Charge storage circuits; pulse modulation. INTERNATIONAL BUSINESS MACHINES CORP. 27 Sept., 1968 [30 Oct., 1967], No. 45999/68. Headings H3T and H4L. A charge storage circuit including a charge applying switch subject to leakage current when off has a voltage dependent upon the charge fed back to the switch to reduce the leakage. In Fig. 2 capacitor 44 is charged by the input signal at 22 when transistors 40-2 and 38-2 are rendered conducting by a signal at 46 and a voltage representing the charge is thus available at the output terminal 34 of a negative-feedback amplifier 48-2. This voltage is fed back both to the source electrodes 76-2 and 77-2 and to the gate electrodes 73-2 to maintain a low voltage across the transistors and thus reduce the leakage. Insulated gate switch transistors are used in the simpler circuits of Figs. 1 and 2 (not shown) while in Fig. 4 one transistor of each type is used, the feedback voltage being derived from a feedback output amplifier and diodes being connected in gate and substrate paths to further reduce leakage. The voltage may be fed back to the substrate and voltage level shifting diodes or a potentiometer may be included in the feedback path (Figs. 1 and 2, not shown).

Filed: 1965-11-02
Abstract: 1,118,134. Packaging-machine. GENERAL FOODS CORP. 2 Nov., 1965, No. 46406/65. Heading B8C. An apparatus for feeding semi-solid bodies, e.g. potato cakes 12 in layers into containers, comprises a conveyer 10 which feeds the bodies on to supports 21 and co-operating fingers 33 which push the bodies off the supports into the containers which are fed to positions 20a, 20b, 20c, 20d adjacent the supports 21 by a pair of conveyers 15, 16. Guides (28), (29), Fig. 5 (not shown), may be provided at the sides of the supports 21 to hold the bodies in position. The bodies 12 are then removed from the supports 21 and pushed into the containers by the fingers 33 which are mounted on a bar 34 which is rigidly connected to a web 46 fixed on bearing blocks 39, 41. The reciprocating movement of the fingers is effected by a pneumatic servo 35 which causes the fingers 33 to move the bodies horizontally off the supports so that they fall into the containers. When the bodies are in the -containers, pneumatic servo 48 is activated and the bar 34, to which the fingers are fixed, is raised. The servo 35 then causes the assembly to move back to its initial position. When the servo 48 releases the bar 34, it is biased downwards by a spring (61), Fig. 4 (not shown). The fingers 33 are then pushed behind the succeeding row of bodies 12. The inner two containers in the positions 20a, 20c are ejected down shoots 72 by pusher plates rigidly connected to a pneumatic servo (83) by a piston rod (82) and a U-shaped frame (80). The filled containers are moved away from .the shoots 72 along conveyer belts 75. The containers in the outer positions 20b, 20d .are then released permitting them to be moved to the positions previously occupied by the inner containers 20a, 20c, where the remain until ejected by the pushers. In this inner position another body 12 is fed on to the body previously fed into each container in its outer position. Sheets of waxed paper are fed between the bodies in each container either by hand or automatically.

Abstract: 1,196,047. Optical playback of magnetic records. AMPEX CORP. 11 Oct., 1967 [12 Oct., 1966], No. 46438/67. Heading G5R. To reduce noise in optical playback of magnetic records, light reflected from, or transmitted through, the record is filtered to pass only that part of the light subtending a preselected solid angle. As shown, a playback system employing the Kerr-effect comprises a light source 14 (e.g. a laser), a polarizer 16 and lens 20 to focus the light on a magnetic recording medium 12. The reflected light consists of a narrow information band 19 and noise signals 21 which are more widespread due to surface imperfections of the medium and which may, therefore, be removed by a filter 24. The filter 24 may be placed before or after the objective lens 22 and may either consist of an adjustable iris or an aperture formed in a plate of opaque material. The method may be applied to systems employing the Faraday-effect. Equations are given by which the location and size of the filter may be determined according to the size of recorded information bits, the wavelength of the light and the focal length of the objective lens 22.

Abstract: 988,916. Variable resistors. BECKMAN INSTRUMENTS Inc. Dec. 12, 1962 [Jan. 15, 1962], No. 46918/62. Heading H1S. In a variable resistor in which a contact bearing carriage 13, Fig. 1, is mounted for rectilinear movement along a resistive element 11, a rack 36 is provided adjacent the carriage 13 on the inner surface of the housing 10 and the carriage is provided with a worm element 35 which is rotatably engaged with the carriage, the worm being slidably but not rotatably engaged with the operating shaft 15 so that rotation of the shaft rotates the worm 35 and due to the worm's engagement with the rack 36, axially moves the worm, and hence the contact carriage, along the resistance element 11. The rack 36 may be terminated inwardly of the ends of the housing, leaving blank areas 47 and 48, so that when the carriage is at one or other end of its travel the worm is partially disengaged from the rack and since the worm is made of a deformable material, e.g. p.t.f.e., nylon, or monochlorotrifluoroethylene polymer, further rotation of shaft 15 will make the worm disengage the rack without damage to the component parts. The resistance carrier 20 is provided with a resistance layer or winding 11 and a conductive strip alongside the resistance layer, and the contact element 12 is provided with a plurality of fingers (Fig. 8, not shown) some of which bear on the resistance layer and some on the conductive strip, contact to the ends of the resistance layer and to the conductive strip being provided by terminal members 24. The housing cover, Fig. 3 (not shown), locates the shaft 15 by a projection on the cover which engages groove 45 in the shaft. Fig. 14 shows an assembly of two potentiometers in which one, 56, is of the type described above while the second has a contact carriage 64 to which the end of the shaft 57 is rotatably attached, thus rotation of the shaft 57 adjusts the position of contact carriage 60 of potentiometer 56 without affecting the adjustment of potentiometer 55 whilst axial movement of shaft 57 adjusts potentiometer 55 without affecting the adjustment of potentiometer 56.
