Abstract: 365,627. Vehicle windows having signalling openings. BIGGS, F., 57, Tavistock Crescent, Notting Hill, London, and LOWE, BEVAN, & CO., Ltd., Clarence Works, Scotland Street, Parade, Birming- ham. Oct. 20, 1930, No. 31386. [Class 20 (iii).] A vertically - slidable vehicle window of the kind having a pivoted signalling flap a is provided with a stop k to prevent opening of the sliding sash while the pivoted flap is open. The stop is spring- pressed to engage the plate o normally and has a projection q adapted to be engaged by the pivoted flap when closed and to be withdrawn thereby so as to pass through a slot provided in the plate. In a modification where two telescopic spring arms are provided, the ends of the arms may be extended to form stops which, when the fla,p is closed, are withdrawn out of the path of the plate o to allow the window to open. Specification 301,590, [Class 20 (iii), Doors &'c.], is referred to.

Title: Improvements in fire control apparatus for determining the allowances for the effect of wind
IPC: F41G3/08
Filed: 1921-11-24
Abstract: 193,925. Barr & Stroud, Ltd., Barr, A., and Stroud, W. Nov. 24, 1921. Modifying scale of readings.- Apparatus for determining wind-correction allowances for gunfire control comprises a model of the projectile or equivalent three-dimensional body mounted so as to be displaceable about one or more horizontal axes under the action of the wind, the device being also capable of azimuthal adjustment in accordance with the training of the gun. Figs. 1 and 2 show an apparatus for determining the wind pressure normal to the plane of the trajectory, comprising a model projectile 1 mounted on an arm 2 rotatable about an axis 3 lying in the plane of the trajectory, movement of the arm being resisted by springs 4, 4<1>. The wind pressure may be indicated on a scale 11 or may be transmitted, to a distance by gears 5, 6, commutator 7, and brushes 8. The body 1 may be a sphere, a flat disc &c. A similar device may be used to indicate the pressure in the plane of the trajectory, or the shaft 3 maybe mounted in a gimbal ring so that both components can be determined simultaneously. The body 1 may be mounted so that it can be tilted to an inclination approximately equal to the elevation of the gun. The Specification also describes the calculating-device shown in Figs. 6 and 7 for determining the deflection and elevation correction. This device comprises a shaft 21 rotated in accordance with the movements of the axis 3 and carrying a multiple cam made up of four elements 20 - - 20<3> with which engages a flexible guidestrip 23. Resting on the strip 23 is a plunger 24 carried in a housing 26 mounted on guide-screws 27, 27<1> which are rotated according to the appropriate function of the range. The upper end of the plunger is formed as a rack 28 engaging a pinion 29 the rotation of which is a measure of the required correction. Specifications 125,455 and 126,798, [both in Class 106 (i), Calculating &c.], 133,974, and 163,341, [Class 106 (i), Calculating &c.], are referred to.

Tools.-A skim attachment for a plough is mounted on the plough body so that manure &c. may pass right over the top if necessary. The plough is provided with a share 8 of substantial length, from the point of which a plate 2 extends obliquely backwards. The plate 2 is in a vertical plane over the edge of the sole plate 10 and acts as a coulter. Its upper part may be formed into a skimming share or may carry a separate concave skim attachment 3 adjustably connected to it by a bracket and screws. The edge 5 of the mouldboard 9 is at a distance from the land side of the plough corresponding to the width of the skim attachment, the gap between it and the sole plate 10 being filled in by a convex body plate. The coulter plate 2 may be made in one with the body plate, share 8, mouldboard 9, or sole plate 10.

Abstract: 430,220. Delivery shoots. BRITISH HAVACONE CO., Ltd., 10, Finsbury Circus, London, and MARSHALL, E. L., Elmside, Garatts Lane, Banstead, Surrey. Nov. 2, 1934, No. 31555. [Class 78 (i)] [See also Group V] A device for delivering biscuits of conical or similar shape from a moulding-machine to a trimmer comprises an inclined shoot, means disposed at the upper end thereof to support the biscuits when they leave the mould and convey them to the shoot, and means situated at an intermediate position along the length of the shoot and adapted to arrest the movement of the biscuits during a regulated time interval from the instant of release from the mould. As shown, the shoot comprises three parallel concave guiding members 1 and is provided at a point intermediate its length with a series of rods 14, two of which extend into each of the members 1. The rods 14 are carried by a shaft 11 mounted on uprights 10<a> on the sides of the shoot. The shaft 11 is provided with an arm 12 connected by a link 13 to an operating arm 8 on a shaft 6 carrying four rods 9 normally adapted to lie one on each side of each member 1. The free end of the arm 8 is connected to controlling mechanism which is also operative to effect the opening and closing of the mould 15, the connection being such that, when the mould is opened, the rods 9 occupy a horizontal position to receive the falling biscuits, and the rods 14 are also in the raised position. The rods 9 are then lowered to deposit the biscuits in the members 1, the rods 14 being lowered simultaneously to prevent the passage of the biscuits until the mould is next opened. More than one spindle 11 and set of rods 14 may be provided.

Abstract: 688,475. Feeding sheets. ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 22, 1950 [Dec. 9, 1949], No. 31618/49. Class 100(i) Labels or sheets are withdrawn from a stack and carried to an intermediate station, where adhesive is applied thereto, by a rotatable member having at least one operative face on which a charge of static electricity has been produced. The operative face may be formed from or covered with polytetrafluorethylene. As shown, bottles 2 are fed in spaced succession to a conveyer 1 by a feed worm 3, the bottles being carried past a labelling station and then to a delivery platform 4. At the labelling station, a gummed label is presented to the adjacent bottle 2 by a feeding member 6, the bottle being rolled-across the label on the member 6 by a pressure wheel 7 rotatably mounted in an arm 8 which is spring-urged towards the conveyer 1. The feeding member 6 is mounted on an intermittentlyrotating shaft 13, and is provided with four feeding faces 14 of polytetrafluorethylene, each face being subjected to a rubbing action by a brush 16, which is rotated and moved laterally when in contact with each face 14, whereby an electrostatic charge is produced on the face. Each charged face 14 takes up a label from a stack 19, presents it to a gumming roller 22, and then carries it to the labelling station. The stack 19 is slidably mounted in a support 21, and is moved towards the adjacent face 14. The gumming roller 22 is reciprocated laterally, and is mounted in a gum bath 23.

Abstract: 263,157. Lecoq, J. R. Dec. 16, 1925, [Convention date]. Indicating, - Adjustment and indicating devices for wireless apparatus &c. of the kind in which a single operating member controls the movement of two members is constructed so that a partial movement of one member automatically changes the scale readings for co-operation with an indicator rigidly secured to the operating member. In one construction, Fig. 1, one element is mounted on the spindle A and another element on the spindle B, a projection on the spindle A engaging with a notched sector 5 on the spindle B. After each rotation of spindle A a pinion 6 operates upon a rack 7 and scaleplate 8 to display one or other of the scales I - - IV in the cover aperture 11 for co-operation with the indicating-pointer 3. In modifications, the spindle A effects the movement of the scales directly, for example, in Fig. 6, a projection 16 on the scale-plate 8 engages a spiral cam groove 15 in the operating-knob 1. The scales may be stationary and a translatory movement given to the indicating-pointer. A cam in the form of a Maltese cross may be employed in place of the sector 5. Three or more adjustable members may be employed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement having scales of rectangular form which are moved by one of the adjustment members through a pin-and-slot connection, the other member being moved independently. This subject-matter does not appear in the Specification as accepted.
