Title: Improvements in or relating to electric air raid warning systems
IPC: G08B27/00
Filed: 1938-07-19
Abstract: 510,050. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd. July 19, 1938, No. 21420. Convention date, May 6. Addition to 495,057. [Class 40 (i)] In the system described in the parent Specification wherein air-raid warning hooters are operated over the contacts of synchronouslydriven switches in response to the transmission of a signal over a power network, the switches are arranged to operate the hooters to give alarms of different character. Each alarm station is provided with two hooters LH, HH of different pitch, connected in multiple to contacts of different lengths distributed over a half of a synchronous switch. The switch normally occupies the position shown and on receipt of a signalling pulse over the network, relay DN pulls up to close the circuit of the driving motor MO over the wiper W. Upon rotation, offnormal contacts ONS are closed to maintain the motor circuit during one complete revolution of the switch. The hooters are operated to give a warning under the control of a second pulse transmitted' when the wiper co-operates with the contact connected to relay AR which when operated remains in the operated position and prepares the circuit of the hooters at contact ar. During the second half revolution of the switch the hooters LH, HH are operated alternately to produce a series of short and long blasts. When the switch reaches its normal position, contacts ONS are released to stop the motor and close a resetting circuit for the relay AR, over contacts ar3. An " All-clear" signal is given of a differently-spaced second impulse which pulls up relay AC to connect the hooter LH directly to the network. Pulses which are not correctly spaced cause operation of relay WO which at contacts WO1 renders the apparatus unresponsive to further impulses. Instead of using electric hooters as shown, compressed-air hooters controlled by magneticallyoperated valves may be employed. The valves are connected to the network by relays connected through rectifier bridges to the contacts of the synchronous switch, The compressed-air hooters may also be adapted for manual operation by a valve which produces different notes according to the direction of operation.

Abstract: 1,144,063. Chlorination of 1 -(trichloromethyl)- alkanols. DYNAMIT NOBEL A.G. 13 May, 1966 [14 May, 1965], No. 21485/66. Heading C2C. A chlorine atom is introduced into a position beta to the hydroxy group of trichloromethyl alkanols of the formula i n which R 1  is an alkyl group and R 2  is an alkyl, cycloalkyl or aryl group, by reaction with chlorine in the presence of actinic light and/or a free radical initiator. The reaction may be effected in the presence of an inert solvent at 20-200‹ C. In the absence of a solvent it is preferred to operate at a temperature above the melting point of the alkanol. A suitable source of actinic light is an U.V. lamp. Specified free radical initiators are acyl and alkyl peroxides and azo compounds. Alkanols containing more than 4 carbon atoms may be obtained as sideproducts, particularly when a molar excess of chlorine is employed. Examples relate to the preparation of 1,1,1,3 - tetrachloro - 2 - methyl - 2 - propanol and 1 - trichloromethyl - 1 - methyl- 2-chloro-propanol-( 1).

Abstract: 1,170,876. Topping, tailing and peeling onions. TRIPAX ENG. CO. PTY. Ltd. 7 May, 1968 [8 May, 1967], No. 21637/68. Heading A4C. An onion preparing machine comprises a means for directing a jet of fluid directly into a slit or slits in a firmly supported onion, that has been topped and tailed, to remove the skin therefrom. The onion is placed between the fingers (29) Fig. 3 (not shown), of a gripping assembly 24, Fig. 2 as it rounds the end of conveyer 14, and is carried through the cutters 35 where a predetermined amount is removed from the top and tail of the onion. The onion is then transferred from assembly 24 to gripping assembly 45 on conveyer 15. The gripping assembly 45 is turned through 90 degrees so that the onion passes longitudinally through cutters 62 which slit the skin and adjacent layers to a predetermined depth. The onion is then carried between two air jets 82, Fig. 13, which may be fixed or are moved in unison with the assembly 45 for a short distance by engagement of projections 51 on gripping assembly 45 with projection 86 so that an air blast is directed into each slit to remove the slit skin and layers from the onion. The onion is then released from the gripper assembly 45 into the delivery shoot 5. The means for topping and tailing the onions, Fig. 4, comprises two rotary cutters 35, one each side of conveyer 14, which are slidably mounted on parallel bars 37. The distance between the cutters 35 is determined by the onions forcing apart cam plates 42. The means, Fig. 11, for slitting the onions comprises two rotary cutters 62 one each side of conveyer 15 mounted for reciprocation on carriages 63 which are in turn mounted for reciprocation on parallel bars 64. Tension springs 72 are connected to the stops 71 and to the extensions 69 to bias each carriage 63 towards each other until screws 70 engage stops 71. As the onion is carried by gripping assembly 45 between the cutters 62, the cutters slit the skin and adjacent layers until the onion is engaged by the cam plates 73. The cam plates then follow the contour of the onion to give the same depth of cut throughout the length of the onion.
