Title: Game of skill using slightly inclined board - has rows of holes in board surrounded by zone inclined towards centre whose width varies from upper to lower rows
IPC: A63F7/30
Filed: 1982-08-09
Abstract: The game of skill uses a slightly inclined board, which can be moved and which has holes in it that balls fall into. The holes are arranged in successive horizontal rows (1,2,3,4, 5) and each hole is surrounded by a marginal zone. The marginal zones are sloped down towards the centre of the hole and their width diminishes progressively from the upper row (1) to nothing in the lower row (5). This makes it easier for the ball to fall into the lower holes than into the upper holes.

Title: Wooden beam, e.g. floor joist - is reinforced by one or more e.g. steel strips secured within it or to exterior
IPC: E04C3/292
Filed: 1983-11-17
Abstract: The wooden beam, intended e.g. as a floor joist, is reinforced by securing one or more strips in a material with greater modulus of elasticity, e.g. by adhesive, nails, screws etc. The arrangement increases the load bearing capacity whilst reducing bending deflection. - For a 75x200mm beam reinforced with a 75x10mm strip, the max. stress in the strip is 80 N/sq.mm and in the wood 10 N/sq.mm. The load may be increased by 75%. Strips may, alternatively, be secured on both sides of the beam, and a composite beam may have alternate layers of wood and steel strips, possibly with resilient layers (e.g. butyl) interposed.

Abstract: ABSTRACT:                A device for optically scanning an information track on a rotating information carrier. The scanning light beam is produced by a cathode-ray tube. The device comprises a position detector which cooperates with the deflection means for the electron beam for accurately following the track. Small variations relative to an average scanning rate can be compensated for by deflection of the electron beam in a direction parallel to the information track. The electron ray tube preferably produces three electron beams of which one serves for reading and the two other ones serve for following the track.

Abstract: Abstract of Disclosure This disclosure includes a color change means for and method of coating surfaces of articles with a spray of powder particles of one color or a spray including a plurality of different powder particles, the particles being entrained in a gas, such as air.  The powder spray device is, preferably, an electrostatic spray device for depositing the particles of powder on a surface to be coated.  A plurality of separate passageways in the spray device, one for conveying each powder, are connected to separate sources of powder.  Particles of the desired powder or powders are withdrawn from the source or sources containing them.  Powder particles flowing into the spray device are conveyed by the passageways to a chamber or compartment within the color change means.  A flow of com-pressed air is introduced to the area where the powder particles emerge from the passageways.  An induced flow of air is ad-mitted into the spray device to the rear of termination of the passageways.  In operation the powder being sprayed is not retained in the device in significant quantity, a substantially uniform powder distribution is achieved in the spray pattern and the powder particles are provided with momentum sufficient to carry the particles to the vicinity of the surface to be coated.

Title: T.d.m. transmission of asynchronously occuring binary data
Inventor: SINGER JOHANNES
IPC: H04L25/48
Filed: 1975-05-21
Granted: 1978-10-10
Abstract: ABSTRACT OF THE DISCLOSURE     A circuit arrangement for facilitating the transmission of asynchronously occurring binary data values is described.  Each binary value change is assigned a multibit pulse group in the frame of a coarse scanning pulse train.  A pulse discriminator, upon the occurrence of a binary value change and upon the arrival of a scanning signal, emits a write-in command which causes the pulse group to be placed in a register.  A counter is provided for counting the number of coarse scanning pulses occurring from the time of occurrence of the write-in command.  Prior to reaching a predetermined count, the counter blocks further write-in commands, and after reaching the predetermined count, the write-in commands are released.  Thus, a correctly formed pulse group is emitted even though the received binary values might be distorted.
