A plurality of leg members are pivotally attached to said base adjacent outer edge portions of same and movable between inwardly folded inoperative positions corresponding to the lower height of the workbench and outwardly and downwardly inclined operative positions relative to said base corresponding to the higher position of the workbench. The pivotal attachment of the respective legs is such that each of said legs is capable of movement in an arc lying in a plane which is at an acute angle relative to the longitudinal and transverse axes of said base. Each said leg includes at its upper end pivot axis defining means, with a portion of said upper end spaced from said pivot axis defining means being shaped to transmit thrust forces to said base and to limit the degree of outward pivotal motion of said leg thus to define the outwardly and downwardly inclined operative position of each leg.

Title: Combustion apparatus utilizing an auger having an integral air supply system
IPC: F23J1/02
Filed: 1976-04-30
Abstract: A combustion apparatus utilizing an auger having an integral air supply system. The apparatus includes a cylindrical combustion chamber containing a rotatable auger. Waste is delivered to one end of the combustion chamber and is conveyed through the chamber by the auger, and ash and the non-combustible residue is discharged from the opposite end while the waste gases are discharged through a cyclone separator to remove fly ash. The auger is composed of a tubular shaft and a hollow spiral flight. Air is introduced into the downstream end of the shaft and flows through the hollow flight and exits through outlet holes in the flight into the combustion chamber. A portion of the air is introduced into the mass of waste being conveyed by the auger to provide primary air for combustion, while a second portion of the air is discharged from the flight into the upper zone of the combustion chamber above the level of the waste, to provide secondary combustion of the waste gases.

Title: Controlling the feed and retraction of the electrode in a spark-machining unit
IPC: B23H7/18
Filed: 1978-02-27
Abstract: The piston rod (8) of a feed drive (7) supported in the machine frame (2) carries an infeed drive (13) guided on the machine frame and having the electrode (16). The feed drive (7), infeed drive (13) and a hydraulic clamp (18) fitted between the piston rod (8) and the infeed drive (13) are connected to the pressure network via control valves (20, 22, 24).

Title: Three stroke engine.
IPC: F02B/
Filed: 1978-10-30
Abstract: The three stroke engine is an internal explosion engine for petrol. It is composed of a single cylinder in which the mix is compressed by means of two pistons, on an axial disposition, one facing the other. With a three stroke cycle, due to the two pistons. One commands the mix admission, which has been introduced into the carters from the carburettor through the vacuum produced in the carters when the two pistons mount to their top dead centre. This procedure is regulated either by the piston skirts or by rotating valves or by plates. The mix is pre-compressed at the carters when the pistons descend to their bottom dead centre. It is decanted to the cylinder once the admission piston frees the cargo transfers. The other piston commands the exhaust pipe for combustion gases on freeing the exhaust ports. These functions are performed in a differentiated way without the need for valves thanks to the lag existing between the two pistons.

Title: Apparatus for selecting a storey call at an elevator system
IPC: B66B1/18
Filed: 1978-12-20
Abstract: An apparatus for selecting a storey call at a transportation installation, especially an elevator system, which contains storey call storages and a scanning device which continuously scans the storey call storages and produces a signal sequence containing the stored storey calls, as well as possessing a selector which signals the location of the elevator cabin. Upon coincidence of the elevator cabin location and the scanner position there is produced a coincidence signal which, in conjunction with an information signal signalling the operating state of the elevator cabin, is delivered to a selector circuit. Both signals act by means of a first NOR-gate and a storage upon a second NOR-gate of the selector circuit. Storey call signals which have been selected from the signal sequence produced by the scanner device and ordered in accordance with the time sequence of their input are delivered to a further input of the second NOR-gate. If there simultaneously appear the information signal signalling the travel readiness of the elevator cabin and the coincidence signal, then at the output of the second NOR-gate there appears a control signal which, in the direction of travel of the scanner device, corresponds to the storey call situated closest to the coincidence signal.

IPC: G05B19/05
Filed: 1980-01-07
Abstract: A programmable controller of the type used to solve relay ladder diagrams includes a memory into which is placed a digital representation of the rungs of the ladder diagram. The dispositions of various switches and coils are periodically sampled by portions of the programmable controller and stored in known memory locations. At appropriate times between sampling intervals, the various memory information are combined and provided to a relay line solver which updates the status of the relay ladder diagram and restores the updated information in a memory. The programming portion of the programmable controller includes UP, OPEN and RETURN keys which may be manipulated by an operator in an appropriate manner for entering the ladder diagram initially into the programmable controller memory or for updating or charging the status of the various rungs of the ladder diagram. The entry keys are such that contact interconnection information is entered into the memory at the same time and by the same keys that are utilized to enter the contact information no separate memory words are required for contact interconnection information. Very complex rungs of ladder diagrams may be entered using the three previously-mentioned keys. The sequence of ladder-diagram entry into the memory of the programmable controller is decided by contact-interconnection information which is displayed to a key operator to facilitate which contact is to be entered next in sequence.
