Patent EP-0211005-A4 (EP)
Title: Transistor inverter interlock circuit.
Inventor: GLENNON
IPC: H03K17/66
Filed: 1985-12-19
Abstract: In an inverter (8), power switches (Q1, Q6) are connected in series across a DC source (EA, EB) and are operated in alternate fashion to produce an AC output at the junction between the switches. Occasionally, however, a condition known as ''shoot-through'' may occur wherein both switches are momentarily closed, resulting in short-circuiting of the DC source and/or destruction of the switches. This problem is solved by an interlock circuit (30) according to the present invention which prevents simultaneous conduction of first and second complementary power switches (Q1, Q2) connected in series across a voltage source. The circuit includes means (LED1, LED2) coupled to one of the power switches for generating a gating signal when the voltage across two of the electrodes (Q1B, Q1E or Q2B, Q2E) of the power switch indicates that such switch is off and means (Q7, Q8, 40, 44, PT1 or Q9, Q10, 50, 54, PT2) responsive to such signal for inhibiting turn-on of the complementary power switch until the gating signal is generated.

Title: Method and apparatus for water vapor control in convection ovens.
Inventor: SMITH DONALD P
IPC: H05B6/80
Filed: 1986-01-08
Abstract: Prior known methods and apparatus for controlling the moisture of food products being cooked in a conveyorized convection oven have typically relied upon the experience and skill of operators in controlling the temperature and humidity by trial and error. The present invention discloses a conveyorized convection oven (20) having a control system for automatically controlling the temperature and the humidity of the circulating air in the oven (20). The convection oven (20) comprises a plurality of cooking cavities (30a, 30b, 30c, 30d, 30e) each having a passage (31) formed therein through which containers carrying the product (P) to be heated are carried by a conveyor (22). A pair of magnetrons (45d, 45d') deliver microwave energy into cavity (30d). Tubes (62) positioned below the perforated floor (60) of heating chamber (28) form columnated jets of air which impinges against the lower surface of the container carrying the food product (P). The air circulates through the cavity (30d) and the air duct (84) and then contacts the water (81) in a water tray (80). The temperature of the circulating air is controlled at or above the desired temperature for food products (P) exiting the oven (20) with the use of a heating element (86) and its thermostat device (87) disposed in the plenum (85). The water temperature is maintained at a temperature below the temperature of the circulating air but above the temperature of food products (P) entering the oven (20) by another heating element (82) and its thermostat device (83).

Abstract: Apparatus for and a method of casting annular concrete articles such as poles or pipes. The apparatus and method comprises establishing a suitable mould (10), defining the desired mould cavity or shape (13) into which wet or uncured concrete is introduced. Thereafter excess water is removed from the concrete by pressing at least a movable internal wall (66) of the mould against the concrete within the mould cavity to pass water therefrom through drainage means (19, 20) associated with the movable internal wall to thereby provide a moulded concrete article having the characteristics of at least a partly cured concrete article whereby the mould can be removed from the article for reuse.

Title: Signal trace control system for pmc.
Inventor: KIYA NOBUYUKI YOKOKAWACHO JUTA
IPC: G05B19/05
Filed: 1987-04-10
Abstract: A signal trace control system for a programmable machine controller (PMC) which controls a machine upon receipt of signals from a numerical controller. Monitoring means (21) monitors the change in signals from a RAM (1) that is to be monitored. As the signal monitoring means (21) detects the change in the signals, a signal is sent to write control means (22) to write the data of RAM (1) to be monitored onto a trace buffer (2). This operation is repeated. This makes it possible to trace the signals only when the content of RAM (1) to be monitored is changed and, hence, to trace the signals effectively with a small amount of memory.

Abstract: Sont décrits un procédé biocatalytique pour préparer des précurseurs optiquement purs de paroxétine, ainsi qu'un procédé pour préparer de la paroxétine à partir de ceux-ci. Un composé précurseur racémique ester trans de paroxétine est tout d'abord préparé. Ce composé comporte un mélange d'énantiomères (3S, 4R) et (3R, 4S). L'énantiomère (3R, 4S) est hydrolysé par voie biocatalytique pour donner l'acide carboxylique (3R, 4S)-trans correspondant ou bien en variante, l'énantiomère (3S, 4R) est hydrolysé par voie biocatalytique pour donner l'acide carboxylique (3S, 4R)-trans au cours d'une réaction catalysée par une enzyme isolée ou un microorganisme. Dans le premier exemple, l'énantiomère (3S, 4R) non hydrolysé est séparé de l'acide carboxylique (3R, 4S)-trans, tandis que dans le deuxième exemple, l'acide carboxylique (3S, 4R)-trans est séparé de l'énantiomère (3R, 4S) non hydrolysé. L'énantiomère (3S, 4R) obtenu à la suite de l'hydrolyse sélective est réduit pour former un précurseur alcoolique primaire (-)-trans-(3S, 4R) de paroxétine. La paroxétine est ensuite formée à partir dudit précurseur.

Title: Cassette for binding strips.
Inventor: COLEMAN JOHN E
IPC: B42B9/00
Filed: 1993-11-04
Abstract: For convenient packaging of plastic bookbinding strips, cassettes which may be securely stacked one upon the other are provided. The end edges of each strip are received in channels formed in opposed side rails. The rails are attached to transverse spacer bars which are preferably detachably connected to the side rails and are interchangeable to accommodate strips of different lengths-e.g., 81/2 inches, 11 inches, etc. Cassettes may be securely stacked one upon the other by means of mating stacking struts extending upward and downward from the side rails. Very short stacking struts may be used when packaging flat female binding strips in the cassette. A detent is provided in the ends of the rails preventing removal of strips until the detent is bent out of position. The cassette is especially useful in equipment which mechanically assembles punched sheets and strips preparatory to binding a book in a binding machine. Projections from the side rails may be used by such equipment to guide and center the cassettes within the machine.

Date Mar. 28, 1996A training idler for guiding a travelling conveyor belt so that the belt follows a central path. The training idler includes an axle adapted to be mounted to a conveyor support frame, a steering roller rotatably mounted on the axle and adapted to be aligned generally transverse to a conveyor belt which will ride thereon, and a pivot connecting the roller to the axle, the pivot defining a generally perpendicular pivot axis about which the steering roller is able to pivot. The steering roller has an outer peripheral surface of generally right circular cylindrical form and has a central region and opposite edge regions, the edge regions having a peripheral circumference which is either greater than or less than the peripheral circumference of the central region. The arrangement is such that, in use, as a conveyor belt riding on the steering roller moves towards one or other edge region, the difference in the peripheral speeds of the central region and that edge region will cause the steering roller to pivot on the pivot axis and steer the belt back to its central path.
