Title: Drop windows or the like
IPC: E05C17/60
Filed: 1974-10-17
Abstract: 1482449 Frictional detents; band brakes T SESSA 17 Oct 1974 [9 Nov 1973] 45128/74 Heading F2E [Also in Division E2] A driving shaft 10 of a vehicle window is braked in its directions of rotation F, F1 corresponding to raising and lowering of the mobile upper part of the window by a spring 12 comprising two parts 13, 14 interconnected by a bridge 15; the coils of portion 13 are adapted to rest under preload against the shaft 10 to apply a braking action thereto while the coils of portion 14 are loose on the shaft 10, the ends 16, 17 of the respective spring portions 13, 14 and the bridge 15 being co-operable with abutment forming shoulders 18, 19 on a housing 11 of the shaft 10 to control the action of the spring 12. When the shaft 10 is rotated in a clockwise direction F, corresponding to upward movement of the upper mobile window part the bridge 15 engages against the shoulder 19, to concel the torque which spring portion 14 applies to portion 13 so that shaft 10 can freely rotate. When the shaft 10 is rotated in the anticlockwise direction F1, the spring portion 13 remains locked on shaft 10 and rotates therewith until its end 16 engages shoulder 18 to thereafter cause the spring portion 13 to loosen and portion 14 to partially tighten around shaft 10 to brake the descent of the window part. When the shaft 10 ceases rotation the system returns to the equilibrium position indicated in Fig. 3 (not shown). Figs. 5-8 illustrate a practical application wherein shaft 10 which is rotated by pinions 23 is of square cross-section and the spring 12 is mounted on a sleeve 32 of square inner crosssection and circular outer cross-section mounted on the shaft 10. A normal torsion spring 28 designed to balance the weight of the mobile part of the window is also provided.

Abstract: 1,177,020. Electric selective signalling. G. RANDOING, J. ROUX and M. POIGNANT. 10 Oct., 1967, No. 46239/67. Heading G4H. An installation for supervising and controlling commercial or industrial operations, e.g. retail sales and stock control, comprises means for transmitting data from a number of field stations to a central station having totalling means and display means for the totals obtained. The field stations may be cash-registers C 1 -C n  Fig. 1, in the several departments of a large store. Associated with each cash register is an electronic register designed to transmit data relating to individual purchases via gates P 1 -P n  and cables A, B to the central station P. The signals from the cash-registers are gated by gates P<SP>1</SP> 1 -P<SP>1</SP> n  to registers R<SP>1</SP> 1 -R<SP>1</SP> n , one for each cash-register, which display the totals of the corresponding cash-registers. Cash-register signals from each department are directed by gates P 1 -P n  to registers R 1 -R n  showing the totals for the corresponding departments. The signals are also all added at D and the grand total displayed at W. A pulse generator 10, Fig. 7 at the central station passes pulses through a divide-by-ten circuit to a first counter the nine stages of which correspond to the nine digits which are to be read out of each cashregister. Of these, five are the decimal digits of the value registered. Others identify the cash-register and its department. Another counter 14 stepped by cycle signals of the first counter enable gates 11 in turn to read out the cash-registers in turn. The nine digits are transmitted each as a train of pulses of corresponding number. At the central station these pulses are gated to appropriate counters 41, one for each cash-register, one 60 for each department and to a grand total counter 80. In another form the digits are transmitted in binary form each being coded on four bits and applied to appropriate binary adders at the central station.

Segments, e.g. comprising three apertures, may then be exposed simultaneously to display a numeral 0-9 by moving more than one shutter through slightly more than the height of an aperture (Figs 3a-j, not shown). The numerals 0-9 may be displayed by seven-fold cam 9 with forms at 36 degree intervals, the forms at each 18 degree intermediate position causing all apertures to be covered to avoid spurious display. Each or both shutter faces 2-8 and backing plate 18 are of contrasting shades to the masking sheet 1, the backing plate may be translucent and illuminated (Fig. 4, not shown) in white or colour. If the backing and masking plates match and the shutters contrast, the system displays in reverse, with a shutter raised to obscure its segment. In place of a cam, electromagnetic or pneumatic/hydraulic means or other silent drive may be used. In an alternative embodiment (Fig. 5a-c, not shown), the faces of the arms projecting above and below the shutters, in a plane just to their rear, replace the backing plate.

Abstract: 1,087,190. Camera cassettes. PENTACON DRESDEN VEB. Nov.3, 1965, No.46531/65. Heading G2A. A cassette (11) Fig. 2 (not shown) (e.g. for cinematographic film) has a contact strip (12a, 12d) whose position is indicative of an exposure factor such as film speed, or the filter factor. When it is inserted into the camera housing Fig. 1 and is correctly located by engagement of stops (12b, 12c) on the cassette with stops 8b, 8c on the camera, the strip (12a, 12d) makes contact from a common contact bar 8a to one of a number of contacts 9. Each of the contacts 9 is in series with a resistance 10 in the energizing circuit of a photo-electric cell 6 which controls the lens diaphragm 3, a measuring instrument 5 also being in the circuit. The resistances 10 are all of different magnitudes, so that insertion of the cassette into the camera completes the photo-cell circuit through a particular resistance which adapts the cell to the film speed, according to the position of the strip (12a, 12d). The dashed lines show alternative positions for other film speeds.
