Filed: 1974-05-29
Abstract: 1472480 Television game systems SANDERS ASSOCIATES Inc 29 May 1974 [29 May 1973 22 Feb 1974] 23712/74 Heading H4T [Also in Division A6] An apparatus for playing a game on a conventional television set or television monitor includes means for generating one or more spots, a parameter of that spot, or one of the spots, being controllable by a player and another parameter of that spot, or another of the spots, being controlled automatically by a pre-recorded modulated audio frequency signal. The audio signal may be amplitude, frequency, or pulse width modulated, for example, and the recording may be in the form of a single or dual track or multiplexed disc or magnetic tape, replayable on conventional equipment. The parameters controlled may be, for example, the vertical and/or horizontal position of the spot, or its size, brightness or colour. The or each player control terminal may include manually operated variable resistors for control of the parameters. In one form of game the player-controlled spot is moved in an attempt to make it collide with the record-controlled spot, and when a collision occurs one or both spots may be automatically extinguished or flashed. Different games may be selected by use of different plug-in printed circuit boards. The recording may also provide an audio signal for simultaneous reproduction via a loudspeaker.

Abstract: 318,374. Royce, F. H. Aug. 21, 1928. Steering-gear is provided with a resilient device or shock-absorber which allows a small amount of relative movement within prescribed limits, characterized in that the movement is restrained by a multiple leaf spring. A friction damping device is also provided. In the construction shown the drop arm comprises two parts c, d pivoted together at e, the part c being secured by bolts c<8> to a boss on the steering shaft a and the part d being connected at b by a ball joint to the drag link (not shown). The inner part c comprises elongated plates c, c‹ secured together by distance pieces and rivets, and the outer part comprises plates d, d0 secured together by distance pieces and bolts d<1>, d". The distance piece d<11> is situated between lugs c' formed on the plates c, c‹ so that relative movement between the two parts of the arm is limited. A boss g mounted loosely on the pivot bolt e is provided with opposed radial arms g<1> on which leaf springs f are threaded and secured by nuts g'. The ends of these springs normally bear against the distance pieces d<1>, d<11> on the part d and against distance pieces c<4> secured between the plates of the part c. When relative movement takes place between the parts the springs are stressed and tend to restore the parts to the normal position. A friction damper is also provided between the parts c, d, and comprises annular friction pads d<5> secured to the plate d, these pads bearing against the plate c and a plate e<7> pressed by a spring c<8> towards the plate d. The plate e<7> can slide on a distance piece on the bolt e but is constrained to rotate with the plate c by means oi a lug (not shown) on the latter engaging with a slot in the plate e'.

Title: Process for the manufacture of polyvinyl alcohols having improved emulsifying and foaming properties
IPC: C08F8/12

Abstract: 277,807. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Sept. 30, 1926. Drawing.-Relates to a method of continuously drawing tube or rod composed of two or more layers of different kinds of glass, or of glass with a coloured stripe. According to the invention, two or more streams of molten glass are caused to flow on to a rotating member, so as to form layers which fuse together, and the combined layer is drawn off the end of the rotating member as a tube or rod. In the construction shown in Fig. 2, a stream of glass, 5, flows from a tank furnace into the interior of a cylinder 2 which is rotated by suitable means and is heated electrically. Other streams of glass flow from containers or shoots 12 into annular reservoirs 8 formed on the outside of the cylinder 2, whence they pass into the interior of the cylinder through apertures or slots 10. The cylinder is inclined downwards, and the combined laver formed bv the different streams of glass is drawn away from the lower end as tube or rod. The cylinder may be replaced by a mandrel and the streams of glass fed on to its outer surface.

Abstract: 942,916. Contact-members for switches; air-break switches. COMPAGNIE GENERALE D'ELECTRICITE. June 25, 1962 [July 13, 1961], No. 24274/62. Heading H2B. Two contact fingers 3, 4, pivoted at 16, 17, are connected by an articulation subjected to the action of springs such that the two fingers grip a double-faced stationary contact 1, 2, and the arrangement is such that the gripping pressure is reinforced by the electrodynamic forces due to the passage of current through the fingers between conductors 20 and 21. Spring 12 maintains contacts 1, 3, closed against the action of spring 5 which in turn maintains contacts 3, 4, closed. Finger 4 has an extension 32 carrying an auxiliary contact 8 maintained in contact with a spark-arresting or arc-rupturing finger 19 by springs 5 and 9 against the electrodynamic repulsive force between the parts 19 and 32. When a latch 22 is released, spring 12 extends sufficiently for spring 5 to be able to open contacts 1, 3. Spring 5 then pushes a lever 7 until it engages a stop 6 whereupon finger 4 begins to move and contacts 2, 4 open. Spring 9 keeps the auxiliary contact 8 closed until an abutment 10 on the rod carrying the finger 19 hits a stop 11 and the contact breaks. With heavy currents the electrodynamic forces assist the opening movement of finger 4 once contacts 1, 3, have opened. The electrodynamic forces hold the contacts closed however until the instantaneous current value is low enough for the spring opening force to overcome the electrodynamic forces and open the contacts.

Abstract: 1,180,940. Servo-systems. FRIED. KRUPP G.m.b.H. 25 May, 1967, No. 24334/67. Heading G4H. A servo control system between a transmitter and a receiver in which both the transmitter and receiver emit Gray code signals representative of their positions includes a logical circuit which compares the Gray codes to determine whether the number of ones from the highest track of the receiver to the highest track at which the codes do not correspond is even or odd to control the direction of movement of the servomotor. The invention utilizes the fact that if the number is even, the receiver is at a smaller angular position than the transmitter and vice versa. In one embodiment (Fig. 4) relay contacts a1<SP>1</SP>-a6<SP>1</SP> (normally open) and a1-a6 (normally closed) are operated by the elements of the receiver Gray code, contacts b1<SP>1</SP>-b6<SP>1</SP> and b1-b6 being similarly operated by the Gray code output of the transmitter. The contacts are cross connected so that if the number of ones is even current flow in channel A to the output a and if the number of ones is odd current flows in channel B to the output b.
