Abstract: 1,227,823. Safety heel binding for skis. LUSSER G.m.b.H. & CO. SKI-SICHERHEITSBINDUNGEN K.G. 3 July, 1968 [3 July, 1967], No. 31785/68. Heading A6D. A safety heel binding for skis comprises the following components:-a guide plate 3 secured to the ski 1 by means of spaced screws 2 (Figs. 2 to 4). Displaceable in the longitudinal direction of the ski 1 in the guide plate 3 is a base plate 4. Soldered on the upper side of the base plate 4 is a reinforcing plate 5. Through the base plate and the reinforcing plate extends a perpendicular threaded bore housing a locking screw 6 (Figs. 3 and 4) the point of which engages into one of a number of conical recesses (Fig. 3) in the guide plate 3 in order to lock the base plate 4 in a position corresponding to the size of the ski-boot 8 which is to be gripped by the safety binding. Fixed at the rear end of the base plate 4 is an upwardly projecting bracket 12 at the upper end of which a control lever 14 is mounted to pivot about the pin 13 in the vertical longitudinal plane of the ski 1. The lever 14 consists of two spaced identical stamped metal plate members engaging at the rear one on each side of a flat-toned upper end of the bracket 12. A selector lever 16 which at its lower end extends between the two parts of the lever 14 is pivotally mounted in the lever 14 by the pin 15. The upper end of the lever 16 is provided with a claw 17 in which fits the stirrup member 18 (Figs. 3 and 4). Screwed on to each of the two limbs of the member 18 is a threaded member 19 carrying a coil tension spring 20 (Figs. 2 and 4). The lower end of each of the springs 20 is provided with a ring portion 21 which engages a hook 22 on the plate 5 (Figs. 2 and 3). The lever 16 can be pivoted together with the member 18 and the springs 20 out of its extreme forward position, shown in Fig. 1, into the extreme rear position, shown in Figs. 3 and 4. A compression member 24 is pivotally mounted at the front end of the lever 14 by means of the pin 23 and has at its lower end a hook 25 (Fig. 4) which engages into a heel bracket 30 screwed to the heel of the ski boot 8 (Figs. 1 and 3). One end of an auxiliary spring 26 is attached to the member 24 at a point between the pivot pin 23 and the hook 25. The other end of the spring engages a ring 27 (Figs. 1 and 3) pivotally secured in the control lever 14 in the vicinity of the pivot pin 15. The front end of the base plate 4 is bent upwards and constructed as a two-pronged fork 29 which is open at the top. In the downhill position (Fig. I), the member 24 projects upwards at the rear and downwards at the front into the space between the two prongs 29, its hook engaging the bracket 30. A projection 31 at the upper end of the member 24 serves as an abutment for the lever 16 in the downhill position (Fig. 1). In the event of a combined frontal and twisting fall, the ski-boot 8 slips forward (Fig. 3), and the lever 16 is urged rearwardly through its dead centre position shown in broken lines to its extreme rear position shown in continuous lines.

Abstract: 1,228,768. Hydrostatic transmissions. DOWTY HYDRAULIC UNITS Ltd. 14 Oct., 1968 [20 Oct., 1967], No. 47913/67. Heading F2D. In a hydrostatic transmission with variabledisplacement pump and motor units control is effected by two spring-loaded variable volume devices so arranged that variation of fluid pressure within a first range adjusts only the pump displacement while variation of pressure within a second range adjusts only the motor displacement. Transmission details.-As shown, the displacements of the pump and motor units 1, 2 are adjusted by levers 5, 6 connected to servo units 115, 23 controlled by a manual selector valve 27. The latter is provided with a hand lever 163 with a cross-member 161 for actuating sleeve valve elements 164, 166 on the ends of hollow plungers 156, 157 formed with axial passages 172, 173 opening into valve chambers 153, 154. These communicate by pipes 126, 125, which incorporate restrictions 56, 57 with the pump and motor servo units 115, 23. The pressures in lines 125, 126 are fed through ports 123, 124 to opposite sides of a fixed differential piston 118 of pump servo 115 to operate a movable cylinder unit 119 with centring springs 135 and connected at 116 to a servo valve unit 136, 142 connected to the pump displacement control member 5. The motor control unit 23, also connected to pipes 125, 126, is a pistoncylinder actuator with a piston loading spring 26. Pressure liquid is supplied by a pump 54 and a reducing valve 83 ensures a fixed pressure drop between pipes 50, 81. Operation.-For forward drive hand lever 161 is rotated clockwise to move valve sleeve 171 along plunger 157, the sleeve 169 remaining stationary on plunger 156. The resulting reduced pressure in chamber 154 is fed to the working space 121 of the pump servo cylinder 119 to operate valve 136 and the pump control 5, the pressure fall and hence the movement of member 5 being proportional to the movement of hand lever 163. The spring 26 prevents operation of the motor servo 23 until the pump control 5 reaches its maximum delivery setting, further reduced control pressure, supplied through a non-return valve 67, then causing the motor displacement control 6 to operate for increased motor speed. Modifications.-As described, the system operates with reducing control pressure, but may be modified to operate with increasing pressure, Fig. 2 (not shown). In addition, the loading of spring 26 may be modified so that motor control member 6 commences to operate before or after pump control member 5 reaches its maximum displacement setting.

Abstract: 1,230,451. Dispensing tape. UNIVERSUMVERPACKUNGS - G.m.b.H. & CO. K.G. 3 May, 1968 [17 Feb., 1968], No. 21044/68. Heading B8F. A device 10 for dispensing and cutting off adhesive tape 11 reinforced with at least one tear filament 16 comprises a frame adapted to receive a reel 12 of adhesive tape and a reel 17 of tear filament, a fixed tape severing blade 28, and a further fixed blade 30 having two cutting edges 31 projecting beyond the edge of the blade 28 in such a manner that the adhesive tape 11a is first incised in the longitudinal direction on each side of the tear filament by the cutting edges of the blade 30, and is then cut off in a transverse direction by the cutting edge of the blade 28. Adhesive tape 11, coated on one side with a pressure-sensitive cold adhesive, is drawn over a guide roller 15 from the reel 12 and picks up the tear filament 16 from the reel 17, the tear filament being affixed to the adhesivecoated side of the tape 11 as the tape and filament are simultaneously fed over the same guide roller 15, before passing between feed rollers 20, 21. After the required length of tape 11a has been dispensed, the device 10 is tilted forward about the pressure roller 20 acting as a pivotal point and the adhesive tape 11a still hanging from the feed rollers 20, 21 is thus tensioned between rollers 20 and 24. During this movement the cutting edges 31 of the fixed blade 30 first make incisions (33), Fig. 5 (not shown), extending along each side of the tear filament and then the tape is severed by the serrated cutting edge of the blade 28, thus leaving a tab (34) in the severed end of the tape 11a still attached to the device, whereby the tear filament of the adhesive tape 1 la can be gripped when the next length of tape has been dispensed, affixed and cut off. As shown the device 10 is in the form of a hand tool but the invention may be applied to automatic or semi-automatic devices.

Abstract: 1,231,008. Automatic control of rolled thickness. BRITISH IRON & STEEL RESEARCH ASSOCIATION. March 21, 1969 [March 25, 1968], No.14325/68. Heading G3R. To correct error in the profile (across the width) of rolled material the error is determined in terms of the constants of a plurality of different curves which in combination define the profile, and signals are derived from the constants to control a plurality of different rolling parameters. It is shown that the profile error may be sufficiently defined by the two term expression Shx (or E) = Px<SP>2</SP> + Qx<SP>4</SP>, where Shx (or E) is the error in thickness reduction at a distance x from the centre line of the material. This is determined by odometer wheels 10 spaced at distances x; these measure the linear extension which occurs as a result of (and is therefore related to) the reduction in thickness. Alternatively, measurements may be made of magnetic characteristics related to stress (and hence reduction in thickness) in the strip. If the profile may be assumed to be symmetrical two of the measurements may be dispensed with. A digital or analogue computer uses known techniques for deriving P and Q from these measurements, and also solves equations given in the Specification for determining the adjustment required to at least two of the following parameters to make P and Q (and hence the error) equal to zero:- input tension, output tension, screwdown position, bending force on the rolls. If the profile is not symmetrical it may be made so by differential adjustment of the screwdown devices. The bending force on the rolls is adjusted by hydraulic jacks between the chocks of the work rolls and back up rolls.

Abstract: 1,231,868. Xerographic developing apparatus. RANK XEROX Ltd. Aug. 6, 1968 [Aug. 9, 1967], No.37506/68. Heading G2H. A xerographic development apparatus has a support 20 for maintaining developer, comprising carrier particles and charged toner particles, adjacent a surface bearing a latent electrostatic image and means to vibrate the support to suspend the developer in a fluidized state in contact with the image, and an apertured development electrode in proximity to the image and biased to the same polarity as the image. An assembly 14, oscillated by a motor 24 through a link 26, has a support plate 20 as described in Specification 1,193,443. Oscillation of the assembly 14 causes developer to become fluidized in development zone 22. Developer can flow freely through a development electrode 28 in the form of a mesh screen. A screen electrode 30 supports a quantity of developer adjacent the image surface. The mesh of the screen is such that toner particles may flow freely, but not carrier particles. A sump 32 beneath the electrode 30 contains developer having an excess quantity of toner particles. During operation, vibrations of the assembly cause charged toner particles to rise through electrode 30. A variable potential 38 maintains electrode 28 at potential slightly above the potential of the non-image areas, e.g. 100 volts positive, while a second variable potential 40 maintains the electrode 30 at a higher potential than the electrode 28, e. g. 4, 000 volts positive. Negatively charged toner particles are repelled by the electrode 28 to prevent particles not associated with carrier particles from entering zone 22. Carrier particles not carrying toner attract toner particles. Thus, toner particles are continuously conveyed from the sump by carrier particles to the image surface. The potentials 38, 40 can be varied to control image density. In a modification, the electrode 30 is replaced by an undulating screen(42) Fig. 2 (not shown) with insulating caps (44) which prevent the upward passage of uncharged toner particles. In another modification, a potential (40) Fig. (not shown) is applied between electrode wires (52) and plate (20), while a potential (38) is applied between the wires (52) and the substrate of the image surface. An insulating screen (54) is apertured to allow the passage of toner but not carrier particles.
