Title: An improved game of the board type
IPC: A63F3/00
Filed: 1961-03-30
Abstract: 1,007,792. Board games. L. R. TUNALEY. March 28, 1962 [March 30, 1961], No. 11622/61. Heading A6H. Apparatus for playing a board game simulating a field ball game, for example cricket, comprises a board marked to represent the playing field, with the positions of the players shown thereon, and a system of tracks marked round the periphery of the board, each track being marked off into subdivisions. The apparatus further comprises two distinguishable sets of playing pieces for movement at the players' will between the playing positions marked on the board, and other playing pieces representing balls for movement over the tracks, this latter movement being determined by throwing dice. Three dice are used in playing the game, two being provided with pips in the conventional manner, but one being coloured differently from the other to distinguish the two as bowler's die and the batsman's die for example, and the third is devoid of pips but has faces of different colours, and is used to decide the further course of the game when the two numbered dice register the same numbers. The various subdivisions of the tracks on the playing board each bear representations of a score, an instruction relating to the game, or an instruction to consult chance cards. The score is preferably entered on a sheet analogous to that used in playing the game simulated.

Title: Improvements in or relating to photographic printers
IPC: G03B27/80
Filed: 1957-04-09
Abstract: 818,433. Photo-electric control of photographic printing. KODAK Ltd. April 9, 1.957 [April 9, 1956], No. 11629/57. Class 40 (3). [Also in Group XX] A photographic projection printer comprising a photo-cell for monitoring the intensity of the light transmitted by the transparency and for adjusting the strength of the printing light includes means for indicating that a print has been insufficiently exposed. A casting 10 supporting the printing gate is movable under motor action M between a vertical printing position and a transparency viewing and loading position (dotted lines). A spring-urged apertured cover 30 holds the transparency flat during printing but lifts away when the casting is swung to the viewing position, and light from lamps 14 in the casting passes through the transparency to the photo-cell 56 and for printing through the aperture 51, and is dimmed when swung away for viewing. The apertured printing gate has a gripper for the transparency which is raised either manually or automatically by pivoted levers. The end of one lever is actuated by the plunger 45 operated by solenoid 49 at the end of each printing cycle by the control system provided the exposure has been sufficient. The exposure control system uses a magnetic amplifier 74 for adjusting the lamp intensity. The response of the photo-electric cell 56 is compared with that of a compensating cell 60 which monitors the compensator lamp 61 having tapped resistances 62 in its transformer circuit, and the output is converted and stabilized and fed through push-pull amplifier tubes to a beam amplifier V4 connected to the control winding of the magnetic amplifier 74 whereby the voltage applied to the printing lamps is controlled. Voltage regulation of the lamps is obtained by means of the limiter circuit including tubes V3A, V3B. The maximum permissible printing voltage is adjusted by potentiometer 91. A toplimit detector circuit determines whether the transparency clamp shall be released and operates a buzzer. It comprises detector tube V5B whose cathode is connected to the limiter circuit and to relay 103. Operation of the buzzer 112 and de-energization of the transparency release solenoid 49 cuts off top limiter relay 103 corresponding to maximum permissible voltage on the printing lamps and prevents automatic release of the gate. The circuitry also provides means releasing the transparency only when the gate has returned to its loading and viewing position, and the holding means are released just long enough for the transparency to fall after which it is moved to its holding position to enable an operator to position a new transparency. The release time is adjustable for different sizes of transparencies. The transparency gate automatically positions itself in the viewing and printing positions at the proper time (Fig. 6, not shown) by appropriate relay control of the reversible gate motor. The arrangement is stated to be adaptable for an automatic photographic colour-printer.

Abstract: 572,846. Impedance networks. GENERAL ELECTRIC CO., Ltd., and ROWLANDS, R. O. July 19, 1943, No. 11722. [Class 40 (iii)] If two filters, one low-pass and one highpass, of known kind comprising a half-section of constant-k type, an M-type half-section and an MM-type half-section are connected to a common resistive load, neither of the filters is properly terminated. To meet this difficulty, when the load is in series with the filters, as in Fig. 1, the filters are converted to the equivalent forms shown in Fig. 2, and the final series element B of each is removed to give the configuration shown in Fig. 3. Each filter is then properly terminated, provided the cut-off frequencies of its constituent half-sections were the same and the values of the parameters m, m were the same for the two filters. The high-pass filter of Fig. 3 may be converted to the form shown in Fig. 5 in order to reduce the number of inductances. Similarly, when the load is in parallel with the filters, as in Fig. 6, the equivalent forms shown in Fig. 7 are obtained and the final shunt elements Bare removed to give the configuration shown in Fig. 8. In this case the low-pass filter may be converted to the form shown in Fig. 10. The relations between the elements are given for the conversion from Fig. 6 to Figs. 8 and 10.

Title: Improvements relating to machines for removing weeds from railway road beds
IPC: E01B27/06
Filed: 1921-04-29
Abstract: 162,622. Scheuchzer, A. April 29, 1920, [Convention date]. Addition to 157,308. Weeds, destroying; hoes.-In a machine for destroying weeds on railways comprising knives which are automatically lifted over the sleepers as described in the parent Specification, the auxiliary motor for raising and lowering the knives is set in motion by an appliance drawn through the ballast and directly actuated by the sleepers. In the form shown in Fig. 1, the knives 15 are movable about an axis 151 and are raised and lowered by lever and rod mechanism connected to a piston in a power cylinder. The supply of steam to the cylinder is controlled by a valve connected by a rod g, a spring, and a tube 32 to a pivoted and spring-controlled lever f carrying a movable rod d which is provided with a pilot roller e moving through the ballast. The roller c is held in the ballast by the engagement of the rod d with a curved arm b<1> of a lever connected by a rod a with a hand-wheel, the lever tending to turn the rod d into a vertical position. When the roller e engages a sleeper, the rod d and lever f are tilted and steam is admitted to the cylinder to raise the knives. When the roller e leaves the sleeper, a spring 43 returns the parts to their original positions and admits steam to the other side of the piston. As the centre of curvature of the arm b<1> does not correspond with the pivot of the lever f, the rod d is pushed along the leve: f towards the knives 15 when they are raised sc as to cause them to clear the sleeper. The lever b is adjusted according to the width of the sleepers. For transport purposes, the rod d is turned up by means of a slotted rod h, a lever c, and a rod a<1> connected to the rod a. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification shown in Fig. 4 (Cancelled) in which the rod d slides in a block pivoted on a sliding piece which is con. nected by link and lever mechanism k<2>, k<3>, k<4> tc a hand-wheel k<1>. The rod d is pressed against a curved arm l on the sliding piece by a spring m. It engages in a curved slot in a spring-controlled arm n on a shaft r, the motion of which is transmitted to the slide valve by an arm o. Different widths of sleeper are allowed for by adjusting the height of the sliding piece. Two pilot rollers may act on the slide valves independently, so that, when the railway is curved or the sleepers are of irregular width, the knives are raised by the first roller which engages a sleeper and are held up until the other roller has left it. This subject-matter does not appear in the Specification as accepted.

Filed: 1917-08-29
Abstract: 128,665. Marconi's Wireless Telegraph Co., and Franklin, C. S., (Marconi, G.). Aug. 29, 1917. Drawings to Specification. Directive wireless signalling.-Electro-magnetic waves are transmitted in, or received from, a desired direction by parabolic reflectors comprising two or more sets of rods, strips, or wires arranged on a parabolic surface around the aerial as focus, each rod being tuned to the aerial. The focal distance is preferably one-quarter of the wave-length. The sets of rods may be arranged in line so as to form a parabolic cylinder, or they may form a true paraboloid. For concentrating vertically-polarized waves, each set comprises vertical alined rods, while for concentrating horizontally-polarized waves, each set comprises curved rods lying in an horizontal plane. Rods arranged on a true paraboloid serve to concentrate either type of wave. The adjacent ends of the rods may be insulated from each other or joined by inductance coils or condensers. The length of each rod is preferably about half a wave-length, but may be greater or less if a condenser or inductance is inserted. The rods may be removed slightly from the parabolic surface, the rods being tuned to a longer wave if moved inwards, and to a shorter wave if moved outwards. For short waves, no earth connexions are necessary; but, for longer waves, the aerial and the lower rods of the reflector are preferably earthed.
