Filed: 1930-02-07
Abstract: 354,695. Light-sensitive control apparatus. GEFFCKEN, H., 62, Steinstrasse, and RICHTER, H., 3, Wiederitzscherstrasse, both in Leipsic, Germany. Feb. 7, 1930, No. 4194. Convention date, Feb. 8, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 118 (i) and 118 (ii).] In lightsensitive control apparatus using, for example, selenium cells to actuate a burglar alarm, roadtraffic signal, or other device when a moving body occults a beam of light falling on the cell 2, this impinging beam is confined within a maximum angle of 10‹ by means, for example, of louvers 3, which may be composed of alternate layers of smooth and corrugated metal sheets. Fig. 2 shows two such selenium cells 1 adjusted to receive the beams from a source of light 4; with this arrangement it is possible to give the alarm only when the moving object exceeds a certain velocity, i.e. when the two beams are successively occulted within a given time. In a modified form of cell, Fig. 3, a lens 6 is used to focus the image of the source of light on the aperture of an adjustable diaphragm 8. A complicated path for the light beam across a room to be protected is obtained by the use of a number of mirrors. Additional safeguards are provided by using two beams of light from suitably spaced sources 4, 19 focused by a lens 6 on to the apertures of diaphragms 17 arranged in front of photo-cells 2, 18, the relays being actuated only when both cells are influenced simultaneously. The light source may have a definite area and shape, the diaphragm apertures being correspondingly shaped.

In four-speed gearing for motor-vehicles between co-axial driving and driven shafts A, B, Fig. 3, an intermediate shaft 14 co-axial with the shafts A, B carries two oppositely-acting one-way clutches F, G, First and second speeds are obtained via a lay shaft 11 constantly geared to shaft A, respectively through a gear 13 slidable on shaft B and a gear 20 adapted to be coupled to shaft B by a clutch 17, 18. Third speed is obtained by coupling shaft 14 to shaft B by a clutch 17, 21, so that drive from shaft A is via lay shaft 11, gears 15, 16 and clutch F to shaft 14 and thence to shaft B, while if shaft B overruns drive is from shaft B via shaft 14 and clutch G to shaft A in fourth speed (direct). Fourth speed from shaft A is obtained by locking the clutch G by a clutch S which may be prevented from engaging except at synchronism by a balking ring 22. In. the alternative arrangement shown in Fig. 4, the lay shaft 11 is constantly geared to shaft B; the gears 13, 20 are on shaft A, the intermediate shaft 14 is adapted to be coupled by the clutch 17, 21 to shaft A for the third speed E (direct), and the fourth speed, obtained by locking the clutch G by clutch S, is an overdrive.. In each case, shaft B drives the vehicle through a reversing gear.

Patent GB-1036011-A (GB)
Title: Pulse detector and demodulator
IPC: H03K9/04
Filed: 1963-02-04
Abstract: 1,036,011. Pulse modulation systems. MARTIN MARIETTA CORPORATION. Feb. 4, 1963 [Feb. 6, 1962], No. 4491/63. Heading H4L. A demodulator for position modulated pulses includes a storage device for storing successively each position modulated pulse as it arrives, means for measuring the time of arrival of each pulse within a predetermined reference period and for producing a voltage amplitude proportional to the relative time of arrival of said pulse by generating a timing wave, and starting a new timing wave in response to each pulse within a reference period that is of greater amplitude than any preceding pulse of the same period, and means for gating out at the end of each reference period a voltage representing the amplitude of the timing wave at the end of that period. By this means the intelligence signal is separated from noise impulses which usually are of smaller amplitude. As shown, in Fig. 1, a train of position modulated pulses, which may vary in amplitude and contain noise pulses, is supplied via a diode 2 passing only positivegoing signals to a storage circuit 3 in which the energy stored will increase only when the pulse voltage amplitude is greater than the voltage already across the storage device. Fig. 2A shows a sample period t1 to t2 containing a position-modulated signal pulse 17 and noise pulses 16, 18, 19 and 20. As a result of pulse 16 the voltage level in storage circuit 3 rises to a higher value, Fig. 2B, and this is detected by a circuit 4 which produces an impulse 21, Fig. 2C. The impulse 21 triggers a pulse 22, Fig. 2D, from a timing reset pulse generator 6 to reset a sawtooth generator 5 which started to operate at the beginning of the sample period, as shown at 10, Fig. 2E. The output of the sawtooth generator 5 again starts to increase until it is reset as shown at 11 by a pulse 24 in response to the pulse 17 which is of higher amplitude than the preceding pulse 16. Subsequent pulses 18, 19, 20 which are of smaller amplitude than pulse 17 do not affect the storage circuit 3 and the timing wave E continues to increase until it reaches a value 12 at the end of the sample period, this value being inversely proportional to the time of arrival of the signal pulse 17. A sample period marker pulse 25, causes the amplitude value 12 to be transferred to a holding circuit 7 as shown at 13, Fig. 2G, the level 15 representing the value transferred at the end of the preceding period. The trailing edge of pulse 25 actuates the timing reset pulse generator 6 and a circuit 8 which discharges the storage circuit 3, and the output from circuit 7 is passed through a lowpass filter in known manner. In the case of quantized signals the reference wave is of staircase form, a transistorized circuit, Fig. 4 (not shown), being described.

Title: Photographic shutter
IPC: G03B7/083
Filed: 1966-02-02
Abstract: 1,64,157. Photographic shutter control. AGFA-GEVAERT A. G. Feb. 2, 1966 [ Feb. 9, 1965; Dec. 1, 1965], No.4593/66. Heading G2A. The exposure time of a shutter is controlled by an electrical circuit including a photo-resistor which is exposed to the prevailing illumination, and also including a key which operates a test circuit, actuating a warning device if the illumination is insufficient. In the arrangement of Fig. 1, the shutter, in tensioned position, comprises a pivoted blade 3, which is obstructing the light path 2 to the film 1, and a second pivoted blade 8 which is not. These are latched in their respective positions by arms 18 and 24. Depression of release rod 15 unlatches blade 3, which is pulled out of the light path by spring 5 to initiate the exposure. At the same time, an arm 19 on rod 15 pushes a spring-loaded lever 45 about its pivot 44, so opening a switch 41 and closing another switch 20. This connects a capacitor 37, Fig. 2 (not shown) in series with the photo-resistor (33) with a D. C. battery (22). When the charge on the capacitor reaches a particular value, a silicon rectifier (38) becomes conductive and energizes an electromagnet 23. This attracts a soft iron plate 25 fixed to lever arm 24, so releasing blade 8 to terminate the exposure. At the same time, the rear end of arm 24 pushes against lever 45, which restores switches 41 and 20 to their initial position, so discharging the capacitor. When test key 27 is depressed, a series of change-over switches are actuated, whereby the photo-resistor (33) is connected in series with a variable potentiometer in the battery circuit. An indicator lamp (40) is also now connected to the rectifier (38). The lamp lights up if the illumination falls below a critical value. In Fig. 3 (not shown) the scheme is adapted to an everset shutter, operated by an opening ring (101) and a closing ring (102). The release (115) has cam edges (119) which engage against a rod (120) connected to the timeswitch circuit, Fig. 4 (not shown). In this embodiment the release rod (115) also functions as the test key, the testing operation being carried out during the first part of its travel, before exposure is initiated. If the lamp does not light, indicating a satisfactory level of illumination, the release is depressed completely to effect the exposure.
