Patent SE-333405-B (SE)
Inventor: GASSER K
IPC: H02P5/74
Filed: 1967-03-21
Abstract: 1,168,563. Control of A.C. motors. BORG-WARNER CORP. 22 March, 1967 [8 April, 1966], No. 13538/67. Heading H2J. [Also in Division H3] The speeds of a plurality of motors are controlled by regulating the frequency of respective inverters from which they are supplied by signals derived from a single variable frequency oscillator 13 and divided in a "countdown" circuit which produces one output pulse for a predetermined (and adjustable) number of input pulses. The system is applied to a plurality of motors driving textile machinery; there are a number of channels, each having its own master inverter and countdown circuit, triggered by the common master oscillator, and there may be more than one motor, such as 44, 48, in each channel, each motor supplied from its own slave (power) inverter. The voltage to each motor is varied by a motor operated variable transformer controlled to keep "volts per cycle" constant. The frequency of the master oscillator is varied by a motor driven potentiometer and relay circuits are described (Figs. 2a, 2b, not shown) whereby, at the press of a "start" button the frequency is increased from zero, but the motors are not energized until a predetermined frequency is reached at each master inverter and individual "run" buttons are pressed. At this point the potentiometer motor is stopped and all motors are energized at this minimum frequency. Operation of a master "run" button then advances the oscillator frequency to maximum, when the potentiometer motor is stopped by limit switches. Various interlock contacts are provided, and there is a "jog" button to operate motors 44, 48 before the minimum frequency is reached. In an alternative arrangement the frequency is never reduced to zero, the potentiometer motor being stopped when the minimum frequency is reached during run down, ready for immediate re-start. The frequency detecting circuits are described (Figs. 3 and 4, not shown, see Division H3). The inverters preferably comprise thyristor circuits.

Title: Releasable window guard assembly
Inventor: SCHWEISS KENNETH K
IPC: E05C19/00
Filed: 1990-10-12
Abstract: A window guard screen (10) and frame assembly (11) installable on the jamb of a building window (W) to prevent unauthorized access therethrough. The assembly screen (10) is fabricated from a single sheet of metal having folded-in margins to define channel-like upper and lower end branches (B) and right and left side branches (B) bordering a planar field that is perforated in a predetermined pattern to admit light and air. The planar frame is dimensioned to overlie or nest within the window jamb and is secured to the walls or face of the jamb by adjustable brackets (15). Integral with the inner surface of the frame and surrounding the opening therein is a slideway socket (L) for receiving the screen, the socket being defined by upper and lower end legs (L) and right and left side legs (L). One side branch of the socketed screen is hinged at its extremities to the upper and lower end legs of the socket by hinge pins slidable in slots formed in these legs whereby the screen is horizontally slidable from a security mode position in which it is confined to the socket and the window is guarded, to an access mode position in which the screen is free to swing out from the frame opening to permit one to exit through the then unguarded window. A releasable latch (22) is provided which engages the other side branch of the screen and is accessible only from the building inside to lock the socketed screen in its security mode position. When released, the latch permits the screen to be slid (21) to the access mode position.

Title: Hydraulic door stop
Inventor: CHATEL CYRILLE
IPC: F16F9/512
Filed: 2000-03-17
Granted: 2001-03-14
Abstract: The door stop comprises a fluid circuit with a cylinder (1) housing a piston (2), a by-pass circuit (3) connecting the two chambers (11,12) and a pivoting flap (332) which moves between a closed position (I0) which prevents flow of fluid between the chambers and open positions (I1, I2). A calibrated catch (34) is attached to the flap and retains the flap in the closed position until a predetermined pressure difference is exceeded due to a force applied to the door which moves the flap into an open position and allows fluid passage between the two chambers. When the force is removed, a spring bias (36) returns the flap to the closed position and prevents the door from further movement.

Title: Switching devices and switching arrangements
IPC: H01H43/06
Filed: 1980-03-12
Granted: 1983-05-25
Abstract: A switching device consists of an elongate member such as a chain or belt including a plurality of elements 1 at least one of which can be moved laterally of the longitudinal axis of the member. The member is preferably flexible and endless and the lateral movement is, in one embodiment, achieved by the provision of tenons 3 and grooves 4 formed integrally with elements 1 and linking them together as a chain. When displaced laterally, an element 1 engages a switching member 5 when the elongate member is driven past the switching member 5 by e.g. rotation of a pinion 2. The device is suitable for use in a time switch when elements 1 act as trips to set a switching programme. Instead of each element 1 being displaceable laterally as a whole, it is possible for only a portion of each element 1 to be so displaceable. <IMAGE>

Title: Throughflow treatment control
Inventor: REED COLIN MICHAEL
IPC: D06C7/00
Filed: 1985-03-04
Granted: 1987-05-28
Abstract: A process in which material (20) is passed effectively continuously through a gaseous treatment chamber (10) by way of at least one open port (12) is improved by applying gas curtains across the material path to form externally adjacent the port a buffer zone (50) between the chamber interior and the surrounding atmosphere, which zone acts generally to balance the gaseous outflow otherwise occurring through the port. The buffer zone is preferably formed by and between two curtains serially spaced nearer to and further from the port, the curtains being respectively formed with gas drawn from without and within the zone. The zone is suitably sustained in varying conditions by control of curtain flow rate in response to a zone parameter such as temperature.
