Title: Tool for cutting eg polygonal opening - has two cutters pivoted scissor-fashion with upper ends rotated by holder around fixed cam disc
IPC: B23Q35/10
Filed: 1981-03-31
Abstract: The mechanism is intended for cutting a contoured opening (e.g. square as shown 14) in a workpiece. It comprises two elements (8) with cutting edges (10) at their lower ends whilst their upper ends (7) are carried at diametrically opposed points in a rotatable (by 5,4 in 2) holder (1) and follow a cam track at the periphery of a non-rotatable cam disc (12) between them. The upper ends (7) are radially movable in corresponding radial slots in the holder (1) and the elements are pivotably connected (9) scissor-fashion at a point between their upper and lower ends such that the forces on their cutting edges (10) hold the upper ends (7) in contact with the cam contour.

IPC: E05C9/04
Filed: 1982-07-20
Abstract: In espagnolette fastenings without a panic function, which are provided on the standing wing (1) of two-wing doors, the espagnolettes (2) are under the effect of a spring (11), seeking to press them into the extended position, and of a blocking device (12) which, with the wing (1) opened, hold the espagnolettes (2) in their retracted position, but during the closing of the wing (1) release them for their extension movement, in which they move with their outer ends in closing holes arranged on the doorframe at the top and bottom and thereby lock the standing wing (1). To prevent an unauthorised pushing open of doors (1) equipped with such espagnolette fastenings as a result of an unpermitted retraction of the espagnolettes (2), even when the gangway wings are properly closed, in their extended position the espagnolettes (2) are to be closed by means of a key-actuable lock (16) and a blocking member (for example, 18) actuable thereby and are to be released only by the actuation of the latter by a key. The closing of the espagnolettes (2) in their extended position can likewise take place by key actuation, but preferably also automatically. <IMAGE>

Title: Decoder unit for subscription cable TV system - detects differences in synchronisation pulse lengths and periods encoded in video signal
IPC: H04N7/167
Filed: 1986-12-10
Abstract: The composite video signal (1) from the pay-TV cable system is fed to a synchronisation splitter (10). The frame synchronisation signal (4,4') is fed to a summing circuit (12) and to a pulse generator (11). The constant length pulse signal (5) is fed to the summer (12).

Patent PT-92289-A (PT)
Inventor: ZDEPSKI JOEL WALTER
IPC: H04N7/32
Filed: 1989-11-10
Abstract: A video signal processing system employs an amplitude compander for reducing the effects of transmission noise. The compander includes a transmitter nonlinear amplitude compressor for amplifying small signals and compressing large signals. A receiver includes an amplitude expander with an inverse transfer function. The nonlinear compressor generates out-of-band frequencies which are removed by a transmitter output filter, producing signal distortion. To compensate for such distortion, the transmitter duplicates certain receiver processing circuits, including the receiver amplitude expander and a filter for generating a prediction signal. The prediction signal is subtracted from the transmitter input video signal before the video signal is amplitude compressed at the transmitter, producing an error signal which is transmitted. The error signal is small if the prediction is good, whereby noise reduction results from compressor gain at the transmitter.

Title: Stepping voltage regulator with a protection device
Inventor: GROZDANOV TONI D
IPC: H01F29/00
Filed: 1995-12-29
Abstract: The regulator is designed for the adjustment of power transformer voltage under load and guarantees protection in emergency cases. It has a special device which within the protection breaker cycle can cut out the damaged contact system and restore the electrical supply and as a result of this the user power losses become minimum. The contact system of the regulator is mobile and connected, on one hand with insulation rods of the reciprocating motion mechanism, and on the other hand - by separable contact plug units - to the fixed contact elements insulation-type mounted on an insulation bottom. A knife contact system is mounted there which is open when the plug contact units are on and is closed when they are off. The reciprocating motion mechanism can be hydraulic, pneumatic, mechanical, electromagnetic or of a mixed type. In one alternative the stepping regulator is mounted on the side of the transformer tank, the insulation bottom being fitted to its wall. The contact system in housed in a metal vessel filled with oil and divided by an insulation barrier to the space of the system and a mechanism for the reciprocating motion, and space of the plug-type contact connection and the knife contact system. In case of emergency in the contact system during the current-less pause of the cyle of the protection breaker, the reciprocating motion mechanism withraws the contact system to a safe insulation distance, the knife contact system closes and the transformer is connected to operate in one position. The contact system can be taken out, repaired and put back again. In another alternative the contact system is a three-phase power switchgear fitted in an insulation cylinder submerged in the oil space of the transformer. The plug-type contact connections and a three-phase knife-type contact system are mounted on the insulation bottom. On its upper side the power switch is connected to the insulation rods of the reciprocating motion mechanism which is mounted to the supporting head of the stepping regulator. In case of emergency the actuation of the protection is analogical to that of the first alternative.
