Abstract: 926.492. Ball projectors. AMPLEFORTH ABBEY TRUSTEES. March 14, 1962 [March 22, 1961], No. 10377/61. Class 132 (2). A ball-projecting device for use in practising ball games comprises a magazine for the balls supported so as to be spaced above the ground or floor, means for effecting discharge of the balls therefrom singly and controlled at a distance by the practising player, and a deflector situated in the path of the discharged ball for deflecting the ball towards the player. As particularly described, the device comprises a ball magazine 16 mounted on a collar slidable along the upper part 14 of a telescopic upright 10, adjustment of the magazine relative to the upright being effected by a hoist cord 19 trained over pulleys attached to the magazine and to the upper part of the stand respectively. The magazine contains a sinuous guideway 26 for the balls, terminating at a discharge orifice 28, balls passing through the latter under the control of a member 33 actuated remotely via a cord 38 by the player using the device. The member 33 is mounted in a housing 31 fixed to the magazine, and comprises two arms 35, 37 the former obstructing the discharge orifice when the member is in the inoperative position illustrated in Fig. 5, and the latter ensuring that only one ball is discharged when the member is in its operative position. The member is brought to the said operative position by pulling the cord 38, against the action of spring 44. The deflector 22 of the device is hinged to a bracket fixed to a collar 49 slidable along the upright 10, so as to be adjustable relative to the horizontal, and to the longitudinal axis of the upright. The device may be modified by providing the deflector 22 with a concave, convex or mesh surface, by providing a striker within the magazine for operation by the cord 38 and for the purpose of ejecting balls therefrom at a greater speed, and by mounting the magazine and deflector as permanent fixtures on a wall. As disclosed in the Provisional Specification, the magazine comprises a trough-like member having upstanding lugs at each end for connection to suspension cords which run over a supporting pulley connected to the ceiling, the magazine having pivoted thereto two separate levers taking the place of the members 35 and 37 respectively.

Title: Method and apparatus for cleaning sheet material
IPC: B32B17/10
Filed: 1957-04-01
Abstract: 807,394. Cleaning sheet materials. LIBBEYOWENS-FORD GLASS CO. April 1, 1957 [April 9, 1956], No. 10488/57. Class 138(1) [Also in Group XXX] In a method and apparatus for cleaning sheet material, e.g. curved glass windscreens, a tank 16 holds a cleaning liquid, vibrating means 26, 27, 28 have vibratory surfaces disposed within the. tank, and continuous rotary conveying means 34 is positioned in respect to said tank for carrying the material below and above the level of the cleaning fluid within the tank and into operating position with respect to said vibratory surfaces. Curved windscreens 45 are washed with the aid of high frequency vibrations applied to the liquid contained in the tank 16 by transducers 26, 27 and 28 which vibrate at over 100 and preferably over 10,000 c/s. Loading and unloading is performed by operators at the platform 33 and the hangers 44 supported on the wheel 34 bring the windscreens through the liquid part transducers 26, 27 and 28 in turn. Thus vibration is applied successively to the rear, the edge and the front of each of the windscreens. Fig. 7 shows a modification in which the Ferris wheel is replaced by an endless chain 116 which describes a rectangular path, supported at four corners by sprockets 114. A baffle plate 127 is used to separate the dirtier cleaning liquid at the point of entry of the windscreens from the cleaner liquid at the point of exit, fresh liquid being added through inlet 128 and dirty liquid leaving at 129, thus producing a contra-flow to that of the glass sheets. The liquid level and temperature may be controlled automatically and the drying of the washed windscreens may be speeded up by the application of air or heat. The screens are supported at their bases by hangers 44 and clamped at their tops by spring loaded clamps 46, Fig. 5.

Title: Selective Calling Communications Systems
Inventor: GRETTEBERG FREDRIK
IPC: H04W88/02
Filed: 1967-03-08
Abstract: 1,161,633. Communication systems. LEHMKUHL A/S. 8 March, 1967, No. 10816/67. Heading G4H. [Also in Division H4] In a selective calling communication system, preferably for radio communication between fixed and mobile or between mobile radio telephony stations a code system is used wherein for each digit in a calling number a signal consisting of two simultaneously transmitted speech frequency modulation signals out of a group of five frequencies # 1 -# 5  is transmitted, an audio frequency signal f 6  being transmitted between each digit. In the embodiment described in which the calling member has three digits the coded signals transmitted to each receiver are applied to a resonance relay coil 3 (Fig. 1) having a series of reeds 4-9 tuned to the frequencies # 1 -# 6 , the relay reeds when they vibrate making intermittent contact with fixed contacts 10-15 to supply signals to code plugs and logic circuits in the receiver. At the receiver being called signals are sequentially transmitted on leads 21, 22; 23, 24; 25, 26 to monostable flip-flop circuits and AND gates 27-31. When the two tone combination for the first digit is received signals applied to terminals 34, 35 charge a capacitor in circuit 27 so that as soon as the tone combination for the first digit ceases circuit 27 changes state and impresses a negative control voltage on input 33 to circuit 28. If at the same time a frequency f 6  is received a capacitor in the circuit 28 is charged so that at the end of the frequency signal a control voltage is applied to input 33 of circuit 29. In a similar manner, if the correct sequence of inputs is applied to the relay 3 control voltages will be applied to the input terminals 33 of the remaining logic circuits 30, 31 so that at the end of the third digit signal an output from terminal 36 of circuit 31 is applied to an indicator circuit 32 to give a short duration acoustic signal and light a warning lamp.

Title: Improvements in and relating to electric transformers for regulating purposes
IPC: H01F29/06
Filed: 1934-04-10
Abstract: 436,718. Transformers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. April 10, 1934, Nos. 10828 and 10829. Convention dates, April 10, 1933 and April 13, 1933. [Class 38 (ii)] An auto-transformer for supplying a variable voltage to a number of load circuits has each limb wound with a plurality of mutually insulated parallel windings w<1>, w<2>, Fig. 1, which are connected to the supply conductors u, v through chokes or resistances d. Each load circuit is supplied from a separate limb of the auto-transformer by means of a brush e which slides directly on the parallel windings and may be of sufficient width to bridge a number of adjacent turns equal to the number of parallel windings on the limb. In order to obtain the same voltage difference between any pair of adjacent turns of the parallel windings, the initial turn of the first winding on a limb carrying say n parallel windings is arranged to enclose 1/n of the magnetic flux of the limb, the initial turn of the second winding is arranged to enclose 2/n of the flux and so on, the initial turn of the last winding being arranged to enclose the whole of the flux. The final turns of the windings embrace different fractions of the magnetic flux so that the balance of voltage in the parallel windings is re-established. In an alternative arrangement, the parallel windings a, b, Fig. 6, are connected through chokes d to different points of an auxiliary transformer t to obtain the required voltage differences between the windings. A similar arrangement may be used when the auto-transformer has three or more parallel windings on each limb. The Specification as open to inspection under Sect. 91 also describes an auto-transformer having three parallel windings a, b, c, Fig. 7 (Cancelled), on each limb and having their ends connected to different points on an auxiliary transformer t. This subject-matter does not appear in the Specification as accepted.

In apparatus in which the developing is effected by diffusion transfer and is particularly concerned with the problem of ensuring that the positive and negative sheets reach the pressure rollers simultaneously, as shown in Fig. 1, original 39 and negative 40 proceed from insert slot 3 at the lower right-hand corner of housing 1, 2 around transport cylinder 10 for reflex exposure by light-sources 11, the original 39 is removed by contra-rotating roller 26 having a roughened or elastic surface to take the path of arrow 43 through exit opening 6, and the negative 40 driven by roller 25 proceeds between guide elements 21, 22 in both container 19. The positive sheet for the transfer, 38, is introduced through insert slot 4 to rollers 27, 28 and proceeds between guide elements 20, 29 to meet the negative at the pressure rollers 23, 24; but is released for such meeting only as result of the advancing negative striking blocking member 32 and causing blocking member 31 connected thereto at shaft 35 to move leftward to its dashline position. These members then return to blocking positions as by action of a spring or otherwise. In another form, Fig. 5, (not shown), but which is the same as Fig. 2 of Divisional Specification 908,538, stacks of both negative and positive sheets are accommodated within the container for successive release by somewhat corresponding blocking members and only the original needs insertion. A drier for the positive is provided also.
