Title: An improved means for the protection of aerodromes, aircraft landing fields and other situations
IPC: F41H5/24
Filed: 1940-07-12
Abstract: 577,933. Fortifications. PICKETT, F. N., and HAMILTON, D. St. A. July 12, 1940, No. 11615. [Class 20 (i)] Means for use in the protection of aerodromes, roads, and like situations comprises a pit sunk into the ground and a hollow head normally resting with its upper surface level with the ground, so that vehicles may pass over it, and adapted to be raised by means of hydraulic, air or screw pressure so as to form a combined fort and an obstruction against the landing of aircraft. In one form a pit is sunk into the ground and is lined with a casing 1 of concrete and an upper sleeve 11 forming a recess to receive the projecting edge of the upper end 3 of an inverted hollow hood with open bottom. The hollow hood is adapted to be raised and lowered by a jack 7 which may be actuated pneumatically by the use of compressed air bottles adapted to be positioned around the jack, and is provided with firing apertures 4 disposed around its surface and a guide roller 12 to engage a groove 13 in the lining. Pedestals 9 supporting firing platforms 5 are in turn supported by the concrete base 8, and a pump 19 is provided to pump out any water which may collect in the base of the cavity. Ventilation apertures 24, 26 are provided in the hood and sleeve respectively and drainage grooves 23 are provided in the sleeve. In a modification, Fig. 6, the raisable hood is counterbalanced by a weight 32 which is adapted to constitute the firing platform and which is attached to the hood by means of a rope over a pulley, so that as. the hood falls the platform rises into a position within the hood. The pulley is supported by one of three uprights 36 projecting upwardly from the base; and which form guides for the hood and counterbalance weight.

Title: Improvements in or relating to teleprinter systems
IPC: H04L13/08
Filed: 1963-03-25
Abstract: 959,760. Telegraphy. SIEMENS & HALSKE A.G. March 25, 1963 [March 23, 1962], No. 11639/63. Addition to 949,721. Heading H4P. The parent invention describes apparatus for use with a plurality of incoming and outgoing lines in which, for each line, the incoming signals are sampled at the bit-centres to derive a distortion-free signal which is passed to the outgoing line. The present invention permits the outgoing signals to be transmitted at a preselected one of a number of speeds which may be different from the incoming signal speed. As described for a single input line, incoming signals at 100 baud are stored in tape store Bd, sampled, and the resultant distortion-free signal sent over an output line al, b1 at 100 baud or over another line a2, b2 at 75 or 50 baud. When data is to be transferred to an outgoing line the tape transport relay TS is energized so that data is read out from tape Bd by sampling the stored data at the bit centres. Sampling takes place at 100 bauds and the sampling pulses, together with 100 baud clock pulses from distributer KS1-KS8, cause actuation of a relay S and also the storage of the sampling pulses on relays D-H. If transmission at 100 baud is required then actuation of relay S provides such transmission over line a1, b1. However, if transmission at 50 or 75 baud is desired, distributer SV1 or SV2 is brought into circuit, thereby scanning contacts d2-h2 of storage relays D-H at the appropriate speed and sending the signals over line a2, b2. The circuitry illustrated is repeated for each input line, except that the three distributers are common to all the lines.

Title: Improvements in or relating to flame supervision devices
Inventor: KERSHAW PETER LESLIE
IPC: F23N5/20
Filed: 1964-03-23
Abstract: 1,079,311. Photo-electric burner control. SATCHWELL CONTROLS Ltd. March 9, 1965 [March 23, 1964], No. 12172/64. Heading G1A. [Also in Division F4] A burner control apparatus includes a first thermal delay device FD which determines a preignition period before fuel is supplied to the burner and a second manually resettable thermal delay device SD which renders the burner inoperative if the flame is not detected by a photoresistance cell P within a predetermined period after the initiation of the supply of fuel. When a thermostat T closes, an ignition transformer I supplying spark electrodes, the coil 3 of a flame relay FR, a first heater 5 of the first delay device FD in series with a heater 12 of the second delay device SD are energized. In the absence of a flame the resistance of the photo-cell prevents the energization of the coil 3 from being sufficient to open contacts 1, 2. The energization of the heater 12 in series with the second heater 6 is insufficient to cause warping of the bi-metal strip 11 of the second delay device SD but the combined heating of the heaters 5, 6 causes warping of the bi-metal strip 4 of the first delay device FD and after a predetermined time the strip 4 closes contacts 8, 10. The latter energizes a motor M supplying fuel to the burner, and short circuit the second heater 6 of the first delay device FD thus increasing the energization of the heater 12 of the second delay device SD. If ignition occurs the resistance of the photo-cell decreases and the coil 3 opens contacts 1, 2 to de-energize the ignition transformer and the heater 12 of the second delay device. If ignition fails the coil 3 does not open the contacts 1, 2 and after a predetermined time the second delay device SD opens a contact 14 to de-energize a warning lamp 16. A rectifying diode D is arranged in series with the photo-cell to provide unidirectional current to the coil 3; and a diode 3a and resistor 3b are arranged in parallel with the coil 3 and provide a path for current induced in the coil 3 by the magnetic field in the coil collapsing during the latter part of each half wave of current. This induced current assists the restified current in opening the contacts 1, 2.

Abstract: 758,475. Photographic dosimeter. BAROZ. N. J. M. P. F. CHASSENDE-. April 28, 1954 [April 30, 1953; April 6, 1954], No. 12264/54, Class'98 (1). Photographic material for measuring the dosage of X, gamma, and ultraviolet radiations comprises two or more photographic emulsions of which only one (the check emulsion) is substantially unaffected by the radiation to be measured and contains a latent image which becomes visible upon developing the material, the appearance of the check emulsion indicating the end of the development. The check emulsion may be one which is substantially insensitive to the radiation to be measured, or may be one which has been exposed to an illumination at least sufficient to attain after development subtantially maximum density. The check emulsion may be a silver chloride, chlorobromide, chloriodide, chlorobromide or bromiodide emulsion and may be accompanied by two other emulsions unequally sensitive to the radiation to be measured and carried on the same or separate supports, which may be of paper, film or glass. The material may be enclosed in an inner envelope of transparent plastic and an outer opaque envelope provided: The emulsions may be coated in distinct areas on a common support. The check emulsion may carry a density reference mark of ink or formed by the localised application of developer before or after formation of the latent image. The production of silver chloride, bromide and bromiodide emulsions is described. The emulsion supercoating may be of increased thickness and/or may be hardened, where a silver chloride check emulsion is used, to delay development. The inside of the opaque envelope may be provided with a coating like that used for carbon papers to facilitate the inscription of identification marks. The photographic material may be self-developing. As shown, a support carries a photographic paper 2 suitable for the range 0-150 Roentgens of gamma radiation, a paper 3 suitable for 100-600 Roentgens, a check photographic paper 1 which has been exposed to light, and a density scale 4 calibrated so that it can be compared with the densities of papers 2 and 3 to determine the dosage. The paper 1 may constitute the density scale if the original latent image is produced by exposure under a sensitometric step-wedge, and it may be detached from the other papers.
