Patent GB-461195-A (GB)
Title: Improvements in electrical systems for the remote indication of speed
IPC: G01P13/02
Filed: 1935-08-12
Abstract: 461,195. Electric signalling systems. WOOLNOUGH, G. L., GRAY, A. H., HARWOOD, H. V., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 12, 1935, No. 22727. [Class 40 (i)] In a system for the remote indication of speed, e.g. wind velocity, the speed of a wattmeter shaft &c., control means, operated by a member moved through a predetermined distance at a speed determined by the speed to be measured, effect the control of indicating means which provide an indication of the time between actuation of the control means and the completion of a predetermined time interval. As shown, control contacts 3 are operated by a member 4 which is driven at the speed to be measured through a slipping clutch 7. A drum controller 1 is driven at constant speed by a motor 2 and is provided with contacts S1 ... S10 which at the commencement of a time interval corresponding to the time of one revolution are closed, but are successively opened during the time interval. When the contacts 3 are closed, a relay A is operated and circuits are closed through the S contacts which remain closed to operate corresponding relays W and indicating devices X, the number of devices X operated being dependent upon the speed at which the member 4 is operated. The operated relays W lock up over contacts h<1> ... h<10> and the contacts of a slow-acting relay 9 which is operated by the contacts 3 and effects cancellation of the previous indication. At the completion of each revolution of the drum a resetting coil 8 is operated to restore the member 4. The speed indicating apparatus is used in association with wind direction indicating apparatus 18 and the arrangement is such that if the wind velocity falls to a negligible value an impulse is transmitted to cause the direction indicator to be moved into a predetermined position and retained therein until the wind velocity again increases. The impulse is transmitted by contacts 13 on the drum controller in the event that relay 15 remains inoperative as the result of non-operation of contacts 3 during the time interval. The impulse transmitted over lead 16 operates relay 17 and thereby operates magnet 24 which moves a catch 26 into contact with the periphery of a disc 20 and closes contacts 27 which closes the circuit of one or other of the relays 28, 29 over a commutator 21. The relays 28, 29 operate coils 31, 32 of the control switches of a motor 23 which drives, through a clutch 30, the shaft 18 until the catch 26 falls into the notch 33 and contacts 34 are closed to short-circuit the switches 31, 32 and thereby stop the motor. Upon the next closure of the contacts 3 in response to increased wind velocity, a resetting coil 37 is operated to release relay 17.

Abstract: 1427547 Exposure control circuit ASAHI KOGAKU KOGYO KK 16 May 1973 [16 May 1972] 23356/73 Heading G2A A TTL exposure control system for an SLR camera has a capacitor C for memorizing a light measurement signal and a switch SW3 connected in parallel with the capacitor C and arranged to be closed after each exposure to discharge transients caused by the opening of the current source switch SW1. As shown, SW1 is closed to initiate exposure, opened by the return of the reflex mirror or shutter button, and then SW3 is closed and opened by a coupling to the film wind. For making a number of exposures in rapid succession, a switch SW4 is closed to by-pass SW1 and keep the circuit energized. Since in this case there are no transients to discharge, a switch SW5 ganged to SW4 is opened to render SW3 ineffective.

Title: Method of manufactoring of pressure hoses and device for carrying  out this method
IPC: B29D23/00
Filed: 1972-05-18
Abstract: 1365221 Hoses KRASNOYARSKY ZAVOD RESINOVYKH TEKNICHESKIKH IZDELY 18 May 1972 23425/72 Heading F2P A hose is made by wrapping an elastomeric tubular lining in a carcass by repeated rotation of both carcass material and lining through steps of equal angle about the long axis of the lining while transparting both lining and wrapper longitudinally of the lining, the lining being filled with fluid during wrapping. As shown in Fig. 1a, a hose lining 2 is laid along one edge of a wrapping strip 1. Both hose and wrapping are then rotated through a small angle at 3 (Fig. 1b) and then rotated through the same angle at 4 (Fig. 1c), 5 (Fig. 1d) and 6 (Fig. 1e) successively to produce a partially wrapped hose. Repeat of the sequence (Figs. 1f to 1k and 1l to 1o) completes the wrapping. A device (12), which is stated to perform the abovementioned sequence as the hose lining and wrapping strip are moved in the axial direction of the lining, is described with reference to Fig. 3 (not shown), and comprises a plurality of guides 13 (Fig. 4), each of which is in the form of one turn of a helix (i.e. the ends defining slot 19 are axially displaced). A series of wheels 18 are accommodated in radial slots and are pivoted on a "ring" axle (20) (Fig. 5, not shown) formed as an helical spring. The ends of axle (20) are secured at the sides of the slot 19. The wheels 18 are thus inclined to the axis of the guide 13 and impart rotation to a tube passed axially through the guide. A plurality of such guides are coaxially disposed in a tubular holder (14) (Fig. 3, not shown). The guide (21) at the inlet end of the device is of planar rather than helical form, and imparts no rotation to,the entering lining. A hose making apparatus (Fig. 2) comprises an extruder 7 for forming the lining 2, a conveyer 11 for transporting the lining to the device 12 of Fig. 3, and a supply of carcass material 1 fed onto the conveyer 11 below the lining. Pull of rolls 22 pull the hose from device 12 and a further extruder 24 applies an outer cover, the bath 27 containing a coolant and lubricant. The finished hose is callected in a tank 28, the hose end being held at constant height byanadjustable pillar 30. Means (not shown) are provided to introduce fluid within the bore of the lining and the end of the hose secured to pillar 30 is unsealed, the height of the pillar ensuring a suitable fluid "head". The device 12 is inclined to enhance the pressure of the fluid. The lining and cover may be of elastomer (e.g. rubber) and the carcass may be of rubberized fabric.
