Abstract: HIGH VOLTAGE MOTOR STARTER ENCLOSURE     Abstract of the Invention A high voltage motor starter enclosure includes a floor mounted vertical section consisting of three starter cells, stacked one on top of the other, each cell being suitable to mount one full voltage, non-reversing, squirrel cage starter having a contactor of the air break type.  Each starter cell consists of four distinct, isolated compartments: a line and vertical bus compartment containing space for incoming line cables and vertical bus; a load compartment containing space for  starter current transformers and motor cables for indivi-dual starters; a low voltage control compartment having a drawout, swing-open compartment door (panel) to provide easy access to meters, relays, pilot devices and terminal blocks for inspection and mainten-ance thereof; and a high voltage contactor compartment containing mechanical and electrical interlocks to minimize electrical hazards, a hinged door to provide easy access to a contactor and related component parts, and to the line and vertical bus, and load compart-ments by removing barrier cover plates.  Wheel assemblies are mounted on each contactor so that the contactor rolls into both fully engaged and disengaged positions upon a contactor rail assembly which is part of a removable tray positioned beneath the contactor to support the same.  The removable tray further includes several mechanical inter-locks, a shutter operator mechanism for operating a shutter plate assembly to isolate the line and load terminals from the contactor, a positive ground connection assembly so that the contactor is grounded in the engaged and disengaged positions, a contactor stop assembly, and a bottom barrier plate for isolating the high voltage contactor compartments of each cell from one another.  A drawout handle moves the contactor carriage upon the rail assembly, draws out the con-tactor disconnecting both line and load connections, and disconnects the primary of the control transformer.  A thumbscrew mounted on the drawout handle functions as a mechanical and electrical interlock.          When the thumbscrew is loosened or disengaged from a mechanical inter-lock of the drawout handle, it disconnects the secondary of the control transformer in the low voltage circuit of the contactor and it permits the drawout handle to be pulled down to draw out the con-tactor to a test position.  A choke in parallel with normally closed contacts is inserted in series with the contactor coil after the coil is energized and the contacts open to act as an economizing circuit.          Control transformer fuses are mounted directly to the power fuse stop bracket to prevent any nonfused protected wire between the high voltage source and the control power transformer's high voltage primary.

Abstract: Abstract of the Disclosure The disclosed invention includes an automatic sewing machine having a low inertia system for translating a work holder relative to a sewing needle.  The work holder is moved in a coordinate system which has been modified so that the movement of the work holder relative to the sewing needle approximates, within predefined limits, a rectilinear coordinate system.  The driving power is provided by a pair of stepping motors each of whose mechanical outputs is connected by a separate cable drive to a work holder support for each coordinate system.  The inertia of the work holder and the support is maintained low by separating the motors from the support. A pair of homing and limit assemblies is also connected to the cable system for preventing the work holder from being moved beyond the defined range of movement and  for automatically positioning the work holder in a predeter-mined home position at the beginning and end of every operation.

Abstract: ABSTRACT OF THE DISCLOSURE          CoA-SPC Bakers' yeast extract which is substantially free of proteolytic enzymes and having a purity of at least 45 fold.  The CoA-SPC having a satisfactory purity can be prepared by freezing and subsequently thawing Bakers' yeast.  The resulting liquid and solid phases are separated.  The solid phase is then subjected to conditions which preferentially solubilize insoluble proteinaceous materials other than the CoA-SPC which are bound to solid phase yeast material.  The resulting solubilized proteinaceous materials are separated from the solid phase containing the insoluble CoA-SPC.  The CoA-SPC is solubilized by contacting this solid phase with the liquid phase which was originally formed upon thawing of the yeast.  The solubilized CoA-SPC is then removed.  The CoA-SPC prepared in this manner contains far less extraneous proteinaceous material than does conventionally prepared CoA-SPC.

Title: Circuit arrangement for a monolithic  integrated threshold switch
Inventor: EINFELDT WALTER
IPC: H03K19/018
Filed: 1978-10-19
Granted: 1982-07-20
Abstract: 31.3.78 ABSTRACT:         In circuit arrangements for monolithic inte-grated threshold switches the switching range of the threshold switch is adapted to the minimum voltage which can occur. As this is 4 V at the most, the switching range, if it is to remain reliable both for the upper and the lower switching point, can at the most be approximately 3 V. In other similar threshold switches with a fixed switching range, i.e. with the so-called fixed hysteresis, spurious voltages of the order of magnitude of the switching voltage range oc-cur, in particular when higher battery voltages are used, which may attain up to + 15 V.  In order to obtain a larger distance to the spurious voltages at least at the higher operating voltages, circuit arrangements are proposed, in which the threshold switch has a switching range which automatically adapts itself to the instan-taneous battery voltage, which is referred to as float-ing hysteresis.

Granted: 1982-05-25
Abstract: SAFETY BRAKING APPARATUS FOR PORTABLE CHAIN SAW    ABSTRACT A chain saw having an improved safety brake actuating mechanism is disclosed. The actuating mechanism includes, a safety lever pivotally mounted on the chain saw housing for movement from an operating position to a braking position in which a brake band is brought into frictional engagement with motive means which drives a cutting chain. A latching member is pivotally mounted on the safety lever for releasable latching engagement with the housing. A spring member engaged intermediate the housing and the latching member exerts a yieldable force on the safety lever which constantly biases the safety lever for movement from the operating position to tile braking position while also exerting a yielding latching force on the latching member. The spring member cooperates with the safety lever for holding the latching member in releasable latching engagement with the housing and for resisting movement of the safety lever thereby preventing inadvertent frictional engagement of the brake band with the motive means when the lever is in the operating position. The spring member is cooperatively engaged with the safety lever for permitting rotation and disengagement of the latching member from the housing as the safety lever rotates from the operating position to the braking position in response to an actuating force acting on the safety lever.
