Title: Aerosol device with heat distributer andanti
IPC: A01M1/20
Filed: 1968-04-22
Granted: 1971-03-15
Abstract: The device produces aerosols, in particulate form, from germicidal, fungicidal or insecticidal mixtures by the action of heat. The molten liquid is placed in a recipient housed in the cavity of a heating block which is in the centre of the apparatus. A firm wide base is provided so that the apparatus, if placed on the floor, cannot be turned over even it be hit; no spilling of the liquid can be caused because of metallic blades placed in the centre and dipping into the molten liquid. The blades prevent children from introducing their fingers into the heater, if this is placed at a low level, they also assist evaporation and so, for the same output reduce the temperature thus reducing any decomposition of the chemical product to the minimum. The device is intended for surgical blocks, sick rooms, offices etc.

IPC: B23Q27/00
Abstract: 1,050,334. Cutting by fusion. KAWASAKI JUKOGYO KABUSHIKI KAISHA. Sept. 18, 1963 [Jan. 21, 1963 (2); March 22, 1963], No. 36725/63. Heading B3V. Main and auxiliary pipes 1, 2 are joined together along a joint line B, Fig. 1, represented by a function of the variable angles # and # which are interrelated by the equation where d 1  and d 2  are the respective diameters of the pipes and h is the perpendicular distance between their axes 1a, 2a; the function is obtained by a mechanism including levers 12, 13, 14, 15, Fig. 5, whose output member T carries a cutting tool 33 and moves it along a line parallel to the axis of the pipe 41 to be cut whilst the pipe is being rotated. Lever 13 has a stationary pivot C adjustable by motor 42 and lead screw 43 to fix the distance h and is pivoted at B to lever 12 which has an adjustable pivoted connection A with slider 10 movable along shaft 11 and driven by the main electric motor 9. Lever 12 thus has a motion corresponding to # and lever 13 has a motion corresponding to #. A vertical shaft 17 transmits rotary motion from C to a stationary but adjustable pivot of lever 14 whose other end is pivoted to a slide block 25 slidable along rail 24 of a carriage R, S which is itself slidable along parallel rails 21. Lever 15 pivoted to the carriage at 27, is rotated about its pivot by a universal shaft 18, 19, 20 connected to the pivot B. The other end of lever 15 has an adjustable pivot connection with a slide block 30 on a rail T which is also slidable along parallel rails 22. Rail T is extended at 31 to carry the tool 33. The pipe 41 is rotated in synchronism with the longitudinal movement of the tool by gearing 40, 39 and shaft 38 which can be coupled by a clutch mechanism 37 to either a shaft 36 driven from shaft 11 with a rotary motion corresponding to 0, or a shaft 35 driven with an oscillating motion corresponding to #.

[Also in Division F2] A roll adjusting assembly comprises a member 6, 7 slidable in the mill housing 1, 2 at each end of the roll 3 by pressure devices 8, 9, 25, 26 and lockable and releasable relative to the housing by a controllable pressure device in the form of a bush 17, 18 which is normally tightly engaged with the member but which can be radially expanded by hydraulic pressure through ducts 21, 22. The fluid flow to the bushes is controlled by a device which is normally biased so that the ducts 21, 22 are connected to exhaust. The upper pressure devices 25, 26 are connected rigidly to the housings and supplied with low pressure hydraulic fluid from a regulator 29, 30. The regulator has a pair of pistons 31, 32 on a common rod 33 whose travel is limited by adjustable abutments 36, 38. The pressure chambers of the regulator are connected to a low pressure source through a second control device normally biased to connect the chambers to discharge. The lower pressure devices 8, 9 permanently urge the chocks 4, 5 towards the upper devices 25, 26. The lower roll 10 may be provided with the same positioning apparatus. Alternatively control piston and cylinder devices 15, 16 connected to clamping devices 13, 14 are used. In operation high pressure fluid is supplied to ducts 21, 22 to expand the bushes 17, 18 and simultaneously the duct 41 is supplied with low pressure fluid to displace the pistons 31, 32 and move the piston-rods 23, 24 of the devices 25, 26. The devices 25, 26 move the members 6, 7 against the force of the balancing devices 8, 9. The connection of the abutments at the end of the travel of the rod 33 causes the ducts 21, 22 to be connected to exhaust.

Abstract: 1,231,396. Monitoring radio-activity. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 31, 1968 [July 31, 1967], No.35145/67. Heading G1A. [Also in Divisions B1 and G6] The radio-activity of a gas stream, e.g. from the stack of a nuclear reactor, is monitored for isotopes which might enter and be retained in the human body by passing the stream through a filter medium on which these isotopes are adsorbed, and for isotopes which introduce radio-activity into the air so that the human body becomes subjected to irradiation from the ambient atmosphere, by detecting the beta and gamma emitters in the gas stream after it has passed through the filter medium. A sample of gas is drawn through duct 4 from the main flow 2 to the stack 1, by a pump 3. The gas sample passes through a duct section 7c packed with charcoal dust, which retains any radio-active iodine in the gas stream. The activity is measured by a pair of scintillation counters 7a. The unit 7 may be provided with automatic apparatus for renewing the charcoal in section 7c with a fresh charge, the used charcoal falling into bin 24. This apparatus is detailed in Fig. 3 (not shown). A differential pressure switch 5 senses when there is a gas flow in section 7c. The gas stream is filtered of charcoal dust by filter 10 and then enters beta monitor 8 comprising a scintillation detector using an anthracene crystal. After this the gamma activity is measured by a pair of scintillation counters 9a. One of the counters of each pair 7a, 9a is provided with a shielding block 7b, 9b formed with slots 7d, 9d through which the radiation reaches the detector. This reduces the sensitivity of the counter with respect to that of its twin and thereby enables the investigation of different activity ranges by the two counters. The blocks each contain a further slot at right angles to slots 7d, 7d in which is located a standard gamma source, This can be moved, by a solenoid, into the main slot 7d, 9d so as to enable calibration or checking of the detector system.

Cams 32, 33 are positioned in accordance with the operating circuit pressure to define the permissible limits of adjustment of the levers 28, 29. To ensure equal power output from the motors 14, 15 to their respective output shafts, the pump delivery lines 12 and 13, and the return lines 16 and 17 are interconnected by lines 18, 19 including restrictions 20, 21 so that the pressure drops across the motors are equal. Excessive pressure differences between lines 12 and 17, 12 and 16, 13 and 16, and 13 and 17 are relieved by one-way valves 38, 39, 41, 42, 44-47 and pressure relief valves 48, 49. The pumps are supplied from a tank 22 via a valve 23, pump 24, cooler 25, filter 26, and a relief valve 27. Two or more railway locomotives may be simultaneously controlled by connecting second of the above transmissions.

Title: Monitoring arrangements
IPC: G08G1/127

Abstract: 1310679 Radio frequency systems MARCONI CO Ltd 13 May 1970 [31 July 1969] 38416/69 Heading H4L A monitoring arrangement for data from a number of mobile vehicles sends a signal from a control transmitter to all the vehicles which each respond (after a delay) by transmitting data, the delay in each case being pre-set to one of a number of different values. The arrangement is described in connection with the interrogation of police cars by a coded control signal every 20 seconds, each car on receipt of this signal loading a different value into a counter which is then counted down by a crystalcontrolled clock so that the cars transmit data at 25 millisecond intervals. The data transmitted, which may relate to car position, fuel reserve &c., is digitally encoded and transmitted automatically.
