Patent DE-2967698-D1 (DE)
Inventor: CUVELIER JEAN
IPC: H04L27/26
Filed: 1979-10-15
Granted: 1990-09-27
Abstract: 1. Method for transmitting periodic electrical signals with a very low frequency-error tolerance, in particular in single sideband mode, in which messages constituted from fixed frequencies taken from a spectrum of relevant frequencies are transmitted, in which one frequency from the relevant frequencies is chosen as a marker frequency, in which, after reception, the marker frequency is used for the demodulation of the received frequencies (fo) and in which the received frequencies, demodulated in terms of useful frequencies (fu), serve to actuate devices with a very low frequency-error tolerance, characterized in that, before their transmission, all the fixed frequencies, including the marker frequency, are shifted relative to a subcarrier and that the marker frequency, shifted by a constant value, is transmitted as a start of message signal ; in that on reception, the received, shifted marker frequency is measured and in that the frequency of a local oscillator (7) of the receiver is controlled in order to make this frequency coincide with a reference frequency (fr) equal to the measured, received, shifted marker frequency, but once more shifted by the same said constant value, this time in the opposite direction, this reference frequency (fr) serving for the demodulation of the received signals (fo) in a demodulator (5).

Title: Portable electric tool
Inventor: CUNEO GIUSEPPE
IPC: B25D17/04
Filed: 1980-10-27
Granted: 1984-02-02
Abstract: An alternate switch actuating mechanism for an electric drill or similar tool which permits the tool to be used in either a portable or stationary operation. The tool has a first handle that includes a first switch actuator for operating the tool and a second detachable handle which carries a second actuator for the switch.

A lock is provided for precluding accidental actuation of the second actuator. The device also includes a reversing switch and an interlock which prevents actuation of the reversing switch when the drill is energized.

Title: Electric traction current-collector
Inventor: FERGUSON IAN CAMPBELL
IPC: B60L5/20
Filed: 1982-10-21
Granted: 1985-10-31
Abstract: An electric traction current-collector, such as is described in United Kingdom Patent Specification No. 1 374 972, has a carbon current-collector block (1) housing a rupturable tubular container (7) for air under pressure applied through a pneumatic control system for a pantograph or other carrier so that loss of air pressure due to rupture of the container causes the current-collector block to be retracted. The container (7) is so thin that, if it is not completely housed and supported, it bursts under the applied air pressure and consequently any defect in the carbon block which spoils complete support of the container causes retraction of the current-collector.

Patent DE-3277197-D1 (DE)
Title: Apparatus for paying off wire from a bobbin
Inventor: GARCIA RICARDO ALBERTO MORENO
IPC: B65H59/04
Filed: 1982-10-07
Granted: 1987-10-15
Abstract: Wire payoff devices are described which are used in conjunction with bobbin supporting cradles typically found in wire stranding and cabling machines such as high speed tubular stranders, bow or skip stranders and planetary stranders. The payoff devices include dancer arrangements each having a pair of pulley wires mounted on a common support member which is itself mounted for independent movements along two substantially orthogonal directions. One of the pulley wheels is effectively fixed and continuously releases the wire along the axis of the cradle. The other or receiving pulley repeatedly traverses the axial width of the bobbin to follow the take-off points of the wire to provide uniform take-off and prevent scraping or chafing of the wire. Movements of the receiving pulley towards and away from the bobbin as a function of the tension of the wire is translated, by means of pivoted lever arms, to a variable frictional force applied to the bobbin which substantially maintains the tension in the wire to a pre-established value.

Title: Aerosol valve safety device
Inventor: BRUNET MICHEL
IPC: B65D83/14
Filed: 1984-02-23
Granted: 1988-06-16
Abstract: A push button (2) is slidably and rotatably mounted in a sleeve (1). The push button is fitted to the valve-operating rod (28) of an aerosol valve (25) fitted in the opening of an aerosol can (26) by means of a dish (22). The inside edge of the dish is crimped to the valve and its outside edge is crimped to the edges of the can. The sleeve has an internal collar (3) which is snap fitted over the neck where the inside edge of the dish is crimped to the valve. Since the sleeve thus engages the valve rather than the can, sleeve size and shape is independent of the size and shape of the can (in so far as there are relatively few valve sizes used in a wide range of can shapes and sizes). Further, by crimping the neck (22c) so that its periphery is polygonal, the sleeve can be prevented from rotating. A safety push button requiring both a turning action and an axial displacement for operation, can thus readily be operated with one hand since there is no need to use the other hand to stop the sleeve from rotating.
