Patent IT-1214250-B (IT)
Title: Transient current recirculating circuit for inductive load
Inventor: MAGGIONI GIAMPIETRO
IPC: H03L/
Filed: 1987-06-30
Granted: 1990-01-10
Abstract: The recirculating circuit has the emitter of a control transistor (Tc) connected to the collector of the power switching transistor (Tpw). The collector of the control transistor and the base of the power switching transistor are commoned. In operation, interruption of the drive to the power switching transistor produces an overvoltage across the inductance (L) connected between the switching transistor collector and earth. An over-voltage of VBE turns on the control transistor which turns on the switching transistor. The control transistor withstands a minimum fraction (1/X) of the current which discharges the energy stored by the inductance, where X is the current gain of the control transistor.

Granted: 1990-04-19
Abstract: The watchstrap illustrated in Figure 1 consists of cylindrical elements (1,2) with a rounded upper surface (12) and joined by pivot pins (6) that guarantee the safety of the connection but allow the elements themselves to rotate through a full circle. The said pins also give the watchstrap its characteristic softness, grip and ability to swivel and wrap around the wrist of the wearer. The pieces are connected to the watchstrap pins by way of a screw (11) that fits into a ring-shaped groove in the pin.

Title: Process for the improvement of metal adhesion and metal adhesion retention of rubber compositions thus improved and articles made from such compositions
IPC: C08J5/10
Filed: 1984-07-24
Abstract: @ Rubber compositions and metal-reinforced rubber ply members have improved metal adhesion and metal adhesion retention to brass and brass-plated metallic reinforcement.

IPC: H01P5/12

Abstract: 1,072,990. Power distributers. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. Oct. 22, 1964 [Oct. 24, 1963], No. 43218/64. Heading H1W. [Also in Division H4] A power-distribution device comprises an array or arrays of probes arranged in a cross sectional plane of a waveguide, the probes in each array being spaced by a distance equal to the width of the guide divided by the number of probes. Thus (Figs. 9, 10, not shown) an array of two probes (2 1 , 2 2 ) may be spaced by half a waveguide width and respectively arranged in a waveguide having arcuate walls (10, 11) or a waveguide having a part-cylindrical short-circuiting wall (16). In the modification of Fig. 6, two arrays of two probes 2 1,  2 3  and 2 2 , 2 4  are arranged in a rectangular waveguide I of width a. It can be shown that the probes remain matched to the waveguide whatever their transverse position therein, providing the above-defined spacing is preserved. Thus, the probes shown in Figs. 6, 9, 10 may form part of a linear or circular array (e.g. the array 7, Fig. 13, not shown) which is continuously moved or rotated in such a manner that groups of probes are successively coupled with the waveguide. Slots are provided in the waveguide walls to allow such movement. Modifications are described in which the probes extend from opposite broad walls of the waveguide and in which they extend across the whole width of the guide. A method of matching the probes is described in which the arcuate end wall 16 has a section of castellated configuration in a plane parallel to the probes.

Abstract: 1486519 Identifying and counting coins NGZ GELDZAHLMASCHINEN GmbH & CO FERTIGUNGS-KG 9 April 1975 [19 April 1974] 14551/75 Headings G4V G4X and G4D Apparatus for identifying and counting coins comprises an optical signal transmitter controlling a counter in which the signal transmitter is formed by an optico-electronic image converter past which the coins are adapted to be guided and which supplies signals representative of the respective coin surfaces, the said signals being fed to a comparator which in its turn feeds the counter with signals associated with the coins. Coins are fed from a trough 13 to a rail 15 by conveyer 14. A rocker member 16 permits coins to pass to rail 18 when in a closed position but when open coins fall on to conveyer 17 and are passed back to the trough. Coins passing along the rail pass image converter 19 consisting of four solar cells 20. A light source 21 projects rays through a condenser 22 to the solar cells. From the rail coins pass through shoot 23 into distributor shoot 24 and thence into through one of passages 27 into a container 29. Shoot 24 is positioned by a step-by-step mechanism 26. Fig. 2 shows how rocker member 16 is rotated to an open position by magnet 38 when it receives a signal from photo-electric cell unit 36 via store 37, that a coin has passed. The member 16 is closed when the counting operation in respect of a coin is completed. When a coin passes image converter 19 there is a decrease in the output voltage of a summation or adding unit 39. If the value is below an adjustable reference level comparator 41 prepares for an evaluation instruction. This occurs when the solar cells 20c and 20d are covered by equally large amounts which causes zero-pasage discriminator 42 to pass from a low level to a high level position. After delivery of the evaluation instruction store 37 is returned to its initial position. Also by means of an eight-channel analogue comparator 43 and a coder 44, a channel number is fed into an intermediate store 45 when there is voltage parity between the output voltage of summation unit 39 and a reference level adjusted by reference level adjusting unit 31. The reference levels correspond to the normal dimensions of the coins of a coinage system. The channel numbers are supplied to a counter 46 which has a valuation stage, an adding mechanism 48, a store 49 and an indicating means 50. A metal senser 51 prevents the use of counterfeit coins. For coin sorting, the difference between a channel number which is stored in an intermediate store 45 and the counter content of a forward and backward counter 54 is determined in a comparator stage 53. Depending on the difference an instruction is given to control means 55 of mechanism 26.

Title: Apparatus for heat-sealing and/or cutting of tubular packaging
Inventor: GUSTAVSSON OLOV ERLAND
IPC: B65B51/30
Filed: 1981-04-16
Abstract: In an appliance for heat sealing and/or cutting of continuous packing sleeves, which are fed along a longitudinal direction through the appliance in a condition in which their cross-sections are expanded (for example, via the introduction of an object which is to be packaged), a pair of combining shoe elements (9, 10) are deployed which contain the heat sealing and/or cutting units, and are supported by respective slides (5, 6), which are both movable under the influence of a mutual drive unit (7) controlled by at least one steering column (3) on a platform (1) and operating between inactive positions, in which the two shoe elements are separated in order to leave free passage between them for the packing sleeve (13), and an active position in which the two shoe elements meet in a largely central position in relation to the packing sleeve's dimensions in the space between the shoe elements. In order to be able to use such an appliance for packing sleeves with differing dimensions in the space between the shoe elements without expanding the area of movement for the two shoe elements, a flexible drag unit (14), whose one end (14') is attached to one of the slides (5), is conveyed across a supported pulley (4) secured in the platform in order to pass, in the opposite direction, a fixed blocking arrangement (16) secured on the other slide (6) which, in order to firmly lock the otherwise freely moving drag unit, is activated via a manoeuvre signal from a sensor device (24, 25) on the first named slide (5), when its shoe (9), during movement against the packing sleeve, reaches a position in which the two shoe elements are located at an almost equal distance from the respective sides of the packing sleeve.<IMAGE>
