Title: An improved game or amusement apparatus
IPC: A63F7/06
Filed: 1921-10-12
Abstract: 189,600. Dyche, E. Oct. 12, 1921. Race games, mechanical.-Relates to apparatus for playing a race game in which two cr more figures are moved along inclined tracks, each figure intermittently kicking a separate ball towards a goal, the keeper of which is adapted to be knocked over backward when struck by the ball. The apparatus is made up of a number of similar units, each as shown. A truck 6 carrying a figure 11 is mounted on an inclined track 7 along which it is propelled by a cord 20 which passes round a jockey pulley 21 and is wound on a drum 22 by the rotation of a handle 30. The figure 11 is provided with a pivoted leg 12, a spring extension 13 of which co-operates with arms 14 on a pivoted rod 15 to give a kicking movement to the leg as the figure advances. The last arm 14<a> is cranked and causes the leg to give a more powerful kick and to shoot the ball 16 towards the goal 18. The goalkeeper 17 is pivoted and when struck with sufficient force, falls over and connects two electric contacts 19 in circuit with a bell, light or other indicator. The driving-handle 30 actuates a conical drum 28 which is pressed upwards by a spring 31 into engagement with the rubber tyre 27 of a wheel 26 attached to one part of a clutch 25, the other part of which forms part of the drum 22. If too much pressure is applied in rotating the handle 30, the cone 28 disengages the wheel 26 and the truck stops, but is prevented from running backwards by a metal strip 49, the end 50 of which engages the tyre 27. The pivoted rod 15 is connected through bevel gearing 32 to two parallel arms 34, 36 coupled by a link 35 and provided with extensions 40, 41. A pin 38 mounted on the cross shaft 37 moves with the arm 36 and is adapted to engage a cam 39 which operates a pivoted forked arm 24 for the purpose of clutching and de-clutching the drum 22. When the truck reaches the goalend of its run a projection 42 engages the extension 40 which rotates the rcd 15, de-clutches the drum 22 and allows the truck to run back down the inclined track to the starting position, where it engages the extension 41 and re-clutches the drum. In order that all the units may be controlled by an attendant, a pivoted rod 44 running the whole length of the apparatus is provided and carries a number of arms 45, each of which is connected by a cord 46 and bell-crank lever 47 to the clutch lever 24 of a unit. Other cords 48 couple the arms to the extensions 40.

Abstract: 390,734. Preventing rattling of windows. MILLICHAMP, E. C., 38, Adding- ton Street, Ramsgate. Sept. 29, 1932, No. 27043. [Class 20 (iii).] Relates to rattling-preventing devices for sliding sash windows of the kind in which an arm pivotally mounted upon the upper part of the lower sash is adapted to bear against the upper sash, thereby wedging the two sashes in their respective guides. According to the invention, the arm B is pivoted to a lug I fitted to the lower sash and comprises two interengaging screw-threaded portions J, C, whereby the overall length of the arm can be adjusted. In the form shown, the lug I is formed by twisting the upper end of a plate A which is secured to the lower sash by screws. The arm B is in the form of a tube and is forked at one end to engage with the lug I and reduced at the other end to receive the screw C. The screw is formed with a milled head D which is recessed to receive a buffer L of rubber or like non-abrasive material. In a modification, the head D is made entirely of rubber or the like.

Heading G1N. in order to measure the moisture content of viscous material, e.g. soap base as it is forced through a cylindrical chamber 52 (plodder), by passing microwave energy through the material, a waveguide 54, 55 is secured to the outside of the cylindrical wall and is sealed off with a quartz or quartz-glass window 56, 57 and a guide path for the microwave signals is formed by extending the waveguide within the cylinder in the form of two parallel plates 50 between which the material is free to flow. Energy from a source 81 passes through the material, and a variable attenuator 83 to detector 82, and also through an attenuator 86 to a detector 87 in a reference waveguide. The outputs of the two detectors are compared at 88 to control a servomechanism which adjusts the attenuator 83 to balance the two signals. The plates 50 may alternatively follow a curved path Figs. 1 and 6 (not shown) or may extend from one side of the cylinder only Figs. 3 and 4 (not shown), the energy being reflected back and compared with a reference using a "magic-tee" junction, Fig. 7 (not shown).

Drawings to Specification. [Class 37] A resistance element composed of finely divided carbon and a nonconducting material, e.g. clay, sand, mica, cement or crushed rock, embedded and baked in an inert carbonaceous binder, e.g. a resin or pitch, is stabilized by impregnating it, after baking, with a fixer comprising a resin such as rosin or shellac or a pitch and a solvent. Bayberry wax, carnauba wax, candelilla wax, montan wax, paraffin wax, beeswax, tallow, linseed oil, tung oil, pine oil, turpentine, Japan wax, stearic acid or other fatty acids or esters thereof, and chlorinated naphthalene and chlorinated diphenyl are specified as solvents.

Abstract: The polyazo dyes of the formula <IMAGE> are obtained by coupling tetrazo compounds of diamines of the formula   <IMAGE> with coupling components of the formulae K1H and K2H (see Claim 1 for the meanings of the symbols I, J, K1, k2 and X). The dyes are suitable for dyeing and printing natural and synthetic materials, in particular natural or regenerated cellulose fibres. The dyeings generally have better wet fastness properties than the corresponding prior art benzidine dyes. A further advantage of the dyes of the above-indicated formula over the corresponding benzidine dyes is that, unlike the latter, they are not toxic.

The triangles CAB, EFD are similar, though of different linear dimensions, and, in   particular C#B=E#D so that EF is parallel to AC (which is fixed). The annular end of jack 15 is connected to the full bore end of jack 16 by the line 17 so that as the jib 10 is luffed, as indicated by jack 20, fluid passes between the jacks 15, 16 the arrangement being such that the changes in the lengths BC and DE equals the ratio of similarity of the triangles CAB, EFD thereby maintaining the support 13 in parallelism throughout the movement of the jib 10. The full bar end of the jack 15 and the annular end of the jack 16 are interconnected via means 21 for accommodating the difference in volume between the two chambers. Two parallelmotion systems as above may be combined in two planes at right angles so that the support 13 may be maintained in parallelism during both luffing and securing of the jib 10, Figs. 9 to 13 (not shown).
