Title: Improvements in or relating to skip winding installations in which the skips are loaded by conveyor belts
IPC: B65G65/00
Filed: 1952-05-16
Abstract: 726,924. Belt conveyers feeding skip hoists. SIEMENS & HALSKE AKT.-GES., and SKIP CIE. GES., May 16, 1952 [May 19, 1951], No. 12499/52. Classes 78 (1) and 78 (4). The skip of a skip-hoist is loaded with a measured quantity of material by a conveyer belt B which is loaded with material S to a constant height when its driving motor runs under the control of switches,. Sa, Se, controlled by flaps, which contact the material. As illustrated the belt is fed from a hopper T, the level of the material in which is preferably arranged to be constant, and the driving motor of the belt is switched off by the switch Sa when the level of material delivered from the hopper T is below a predetermined level. When sufficient material has been carried along the belt to operate the switch Se the driving motor is again switched off until a further switch (not shown) is closed by the arrival of a skip. The belt then delivers the whole of its contents to the skip, suitable flaps or slides in the base of the hopper T being closed. A photo-cell L or other means detecting the height of the material in the skip may stop the belt if the skip is overloaded. The photo-cell may also control a signal indicating that winding can be started. Flaps K1, K2, K3 resting on the material operate corresponding rotary switches which control corresponding columns of lamps so that the assembly of the lamps provides an indication of the profile of the material on the belt.

Abstract: 1387172 Co-ordinate measuring instrument AGA AB 17 March 1972 [23 March 1971 18 Feb 1972] 12588/72 Heading G1M A measuring instrument comprises a beam 2, a light source 1 directing a laser beam along the beam 2, and at least one light deflector 7 for directing the laser beam on to a measuring post A. As shown in Fig. 1, a single deflector may be provided on beam 2, and moved so that the deflected beam impinges successively on posts A and B, the distance between the posts being indicated by the travel of the deflector 7 on the beam 2 as indicated by scale 4. An indicator 5 may be set at the position at which the beam impinges on post A. In alternative embodiments, Figs. 3 and 4 (not shown) a pair of deflectors may be provided for deflecting the laser beam on to the two posts simultaneously, and the distance between the two deflectors may be indicated by an integral tape measure. Mechanical or electrical counting arrangements may be provided for determining the position of the deflectors along the beam 2. A further beam 3 may be provided at right angles to beam 2, and carry at least one deflector 8. Light may be deflected on to the deflector 8 by means of deflector 7 when placed at the end of beam 2, or by a further deflector so positioned. The deflectors may comprise prisms such as pentaprisms Fig. 4 (not shown) or mirrors which are mounted in a housing 21 Fig. 6, mounted on a slide 20. A pair of spirit levels at right angles, or a single circular spirit level allow the housing 21 to be adjusted so as to be horizontal. In Fig. 6, the laser beam is deflected by the triangular prism 135, and a beam L13 falls on a scale 19 to indicate the rotational alignment of the prism 135 about a vertical axes in relation to the incident laser beam L. The levels and scale 19 may be replaced by electronic devices which actuate alarms or control devices for adjusting the level of housing 21 and the rotational alignment of prism 135. The posts A, B may carry scales for indicating the Z coordinate.

Abstract: 717,621. Eggs, cleaning. COPE, WHELON & CO., Ltd. May 19, 1953 [May 19, 1952], No. 12661/52. Class 28(2) Eggs are cleaned by a pair of yieldingly spaced rotated brushes 4 as they are moved along a pair of spaced rubber covered support rollers 2 by a rotated wire helix 3. The upper part of the helix 3 pushes the eggs along, the sides of the upper part bearing on and enveloping the rollers 2 while the lower part has fixed end guides 20, 21. The helix is rotated by its attached end ring 17, the holes 18 of which are engaged by a pin 19 on one of the rollers 2, the rotation being the equivalent of gear wheels. The rollers 2 and brushes 4 are rotated planet-wise by a handle 6 through end gear wheels including an internal toothed ring 8. The rollers 2 are rotated through ball and pin type universal joints. The eggs are hand placed on the rollers 2 through an opening 26 partially covered by a hood 27. A spray pipe 29 supplies cleaning liquid to the eggs. Further liquid is supplied in the semi-cylindrical trough 1 in which the helix rotates. A window 25 is provided in the hinged lid 24 of the trough 1. The brushes 4 may have longer tufts at some places. One end of the brushes is mounted in an adjustable plate 14 so that the brushes can be spaced further from the rollers 2 to suit larger eggs. The brushes are also free to rise and fall since their end spindles are mounted in slots in one end plate. Specification 683,307 is referred to.

Filed: 1946-04-30
Abstract: 611,454. Fluid-pressure servomotor-control systems. LARSSON, C. I. April 30, 1946, No. 13093. [Class 135] [Also in Groups XXII and XXIII] A machine tool for reproducing a pattern has a spring-loaded feeler 14 in the form of a longitudinally displaceable but non-rotatable rod which is in contact with the pattern 10 and carries on a threaded portion a nut 17 connected to the control valve 23 of a hydraulic servomotor 24. Axial movement of the nut and feeler rotates the motor which actuates the transverse feed mechanism of the machine and screws the nut along the feeler to close the control valve. The pattern, mounted in a holder 9 in threaded engagement with a shaft 11 connected by bevel gears 12 to the longitudinal feed mechanism of the tool, is rotated from the work-piece 2 by bevel gears 7 and a shaft 8. The nut 17 is secured to a gear 18 meshing with a pinion 28 mounted on the servomotor shaft which is connected through a self-locking transmission means 29-32 to the transverse feed mechanism of the tool. When the pattern produces axial displacement of the feeler in one direction or the other, a swinging arm 21 pivoted at 20 actuates a setting means 22,for the control valve 23 which then permits pressure fluid to flow through conduits 25, 26 to rotate the motor in one direction or the other to actuate the transverse feed mechanism of the tool while the pinion 28 screws the nut 17 back to its original position with respect to the control valve, thereby closing the latter and arresting the transverse movement of the tool. By altering the gear ratios between shafts 5 and 11 and 6 and 27, the scale of reproduction may be varied. The invention may be incorporated in machines performing milling, grinding or cutting operations and which work on metal, wood, textile fabrics or leather. The work-piece and pattern may be stationary.

A photosensitive member for use in electrophotography comprises a polyester film which has been surface treated with a sulphonating agent and a layer comprising an organic photoconductor, a treated surface of the film lying between the photoconductive layer and the interior of the film. In one embodiment the photoconductive layer may be directly on the treated surface whereas in another embodiment an intermediate electrically conducting layer is disposed between the photoconductive layer and the treated surface. The polyester film is sulphonated be immersing it in concentrated or fuming sulphuric acid, a mixture of sulphuric and phosphoric acids, sulphuryl chloride or chlorosulphonic acid, removing the film and washing the film with water. The surface of the polyester is thereby changed from a hydrophobic to a hydrophilic state. The electrically conducting layer may be provided by a coating of poly-(N,N-dimethyl-3,5-methylene) piperidinium chloride, polyvinylbenzyltrimethyl ammonium chloride, a water soluble cellulose derivative, a protein, an inorganic salt, a polyhydric alcohol or a surface-active agent.
