Title: Strip thickness control system - for a reversing cold rolling mill
IPC: B21B37/54
Filed: 1972-09-28
Abstract: Regulation of the thickness of a strip treated by a rolling mill, particularly a cold rolling reversing mill, starting from an uncoiler driven at variable speed, of the type according to which the angular velocity of the uncoiler is acted on, comprises raising the linear velocity (V1) and the variations (J1) in strip thickness entering the rolling mill, raising the linear velocity (V2) of the strip leaving the mill and regulating the agular velocity of the uncoiler in such a way that (V1) (V2) and (J1) satisfy the relationship. V1 = r, V2 - r V2J1 in which (r) is the ratio of the strip thickness at the outlet and inlet to the rolling mill.

Title: Hard and soft water mixing valve - simultaneous operation of three valves gives full control of mixing ratio
IPC: F16K11/04
Filed: 1973-07-12

Title: Torsional vibration damper for motor vehicle clutch - has friction damper and non-linear torque-deflection characteristic
IPC: F16F15/121
Filed: 1973-08-29
Abstract: The drive from the outer clutch plate (18') is taken through the springs (20A), (20B) and (20C). The two springs (20A) are diametrically opposite and are deflected when any torque is transmitted. The two springs (20B) are compressed once the torque transmitter has overcome the springs (20A). Finally at maximum torque the four springs (20C) are compressed. This successive engagement of the springs produces a non-linear relationship between torque and angular deflection, so preventing the build up of torsional oscillations. Drive is transmitted to the hub (10) by spring loaded discs until the deflection is sufficient to engage the teeth (12) so that friction damping is provided over the small angular deflection produced by low torque.

Title: Converting mechanism for bed-settee - re-positions part supporting user's lumbar region in pillow position
IPC: A47C7/46
Filed: 1973-08-30
Abstract: A bed-settee normally has a cushion or similar, against which the user rests his lumbar region, which has to be removed before the settee is transformed into a bed. In the present model, the cushion is part of the settee and instead of being removed it will be re-positioned to form a pillow. The main advantagees of this built-in mechanism are an improvement in its aesthetics due to reduced width of the settee back and it conceals the fact that the settee is a bed, the fact that the cushion is attached to the settee. The lower settee frame typically unfolds to form a flat bed type support surface.
Patent FR-2260782-A1 (FR)
Title: Electrical circuit for turbine flowmeter - compensates for inaccuracies due to turbine inertia particularly during interrupted flows
IPC: G01F1/08
Filed: 1974-02-07
Abstract: Measurements of flow using turbine flow meters in which the flow is measured by the number of turns of the turbine are inaccurate when flow is interrupted, due to inertia of the turbine. An electrical circuit senses and compensates for this inaccuracy. The output (E) of a detector coil associated with a turbine is amplified (5) and the positive and negative half cycles of the signal are separated by a diode rectifiers (8, 9). The positive signals are applied to an integrator (10) while the negative signals are passed to a voltage comparator (11). A controlled switch (12) is connected between the integrator output and the second input (C2) of the comparator. The negative signals are applied to a monostable (14) controlling the switch (12) and also to a second monostable (15) which resets the integrator to zero. A monostable (18) at the comparator output provides counting signals (5).

Abstract: 1477206 Vehicle bumpers ROBIN PRODUCTS CO 17 May 1974 [21 May 1973] 21954/74 Heading B7J [Also in Division B6] An elongate resilient trim member 26 suitable for mounting on vehicle panels and bumpers for ornamental and protecting purposes, has a base surface 32 adapted to be mounted on a support surface 20 having one or more apertures therein, and one or more integral connectors 40 or 140 projecting from said base surface and engageable in the apertures in the support surface for mounting the trim therein, the connector having opposing substantially parallel side walls 42 with a detent 46 on one or both side walls, having a camming surface 50 inclined to the projecting axis of the connector and facing away from the plane of the base surface, and a locking surface 52 also inclined to the said axis and facing towards the plane of the base surface, there being resiliently collapsible further walls 44 between said side walls, the collapsible walls being collapsible between the side walls upon insertion of the connector into an aperture in the support surface. The trim member may be a moulding made of resilient polymeric material, e.g. high density polyethylene. The camming surface and locking surface are preferably spaced apart by a shoulder surface 54. The collapsible walls are integral with the side walls, and are resiliently collapsible by virtue of their concave shape and the flexible nature of the material from which they are formed. On insertion of the connector into an aperture, the walls 44 collapse inwardly under pressure from the side walls 42 from the action of the camming surface against the edge of the aperture, and then recover after insertion beyond the shoulder 54 to cause the locking surface to engage against the inner face of the support surface, as shown in Fig. 4. The trim member may provide a trim assembly for a bumper 20 with over-riders 22, consisting of a central trim 26, two end trims 28 and over-rider trims 30. Connectors as described, moulded integrally with the trim strips, are engaged in apertures 34 and 36 in the bumper and over-riders for mounting the trim. In a preferred embodiment, the apertures 34 are longer than the corresponding width of the connectors while one aperture 36 closely conforms to the dimensions of the connector (Fig. 2) to accurately locate and centralize the trim on the support. This arrangement allows the trim to be fitted to a curved or angled surface, and also allows for manufacturing tolerance variations.

Title: Converter for electric energy - has transformer with several input windings and one output winding and power transistor structure (BE300776)
IPC: H02M3/28
Filed: 1976-02-03
Abstract: The converter high power transistor structure is connected to one end of a main input winding with a tapping, and a second, low power transistor structure is connected to the other end of this winding. This results in the voltage, applied to the converter, making the two transistor structures consecutively conducting, and the core being magnetised in opposite senses, while a rectifier circuit connected to the output winding is conducting only at the same time as the high power transistor structure. The first transistor structure control electrode of one or several converters is connected to a control circuit, so that the first structure is tripped from its conducting state before the core is saturated, and is again made conducting immediately after the second structure is blocked.
