Abstract: 1486814 Heating and cooling railway vehicles ALEX FRIEDMANN KG 5 Dec 1974 [6 Dec 1973] 52598/74 Heading F4V In a railway vehicle, heating and cooling apparatus comprises an air heating and cooling unit (not shown), ducts 1, 2 leading therefrom to the passenger compartments of the vehicle and supplied respectively with heated or cooled air and with heated air, and within each compartment, a baffle 4 within duct 1 defining a passage 5 which communicates with an outlet shaft 6 via openings (6<SP>1</SP>, Fig. 3) in duct 1, a pivoted flap 11 at the inlet to passage 5, and an air outlet 7 in duct 2 controlled by a shutter 8 which is actuable by an electromagnet 10 in response to a thermostat in the compartment, the shutter 8 and flap 11 being linked by a lever mechanism 13 whereby the total quantity of air delivered to the compartment is maintained substantially constant regardless of the positions of the shutter 8 and flap 11. During a compartment cooling mode of operation and upon a temporary demand for heating, the shutter 8 is opened and the flap 11 simultaneously moved to a position in which air flow through passage 5 is substantially reduced. The temperature of air delivered to the duct 1 is controlled by a thermostat responsive to the temperature of air outside the vehicle. The flap 11 is supported by a bearing 14 having a flange 16 secured to the outside of the duct 1.

Title: Telecommunications exchange systems
IPC: H04J3/07
Filed: 1972-11-15
Abstract: 1397758 Pulse code multiplex systems SIEMENS-ALBIS AG 15 Nov 1972 52712/72 Heading H4L A p.c.m.-t.d.m. exchange is synchronized to an incoming data frame by blocking its clock output for an appropriate number of bit periods, thus generating so-called blind bits containing no information nor control data. A data frame from a neighbouring exchange is recognized by its synchronizing bit (Be, Fig. 1, not shown) and is delayed upon reception by the amount by which Be precedes the startbit (Ai) of the frame of the receiving exchange. This delay is effected by clocking the received data into a buffer register PS Fig. 2, via gates EG controlled by a decoder Dex and counter Zex, at the received data bit-rate extracted at Reg; and then clocking out the buffer data at the local clock rate set by clock TG. If, however, the delay to be effected is found to be less than a certain minimum value γ, a blind bit is inserted. To do this, an AND gate GU detects whether during a pulse of the duration γ form Z s , a synchronizing bit Be is received from another exchange this being sensed by a synchronizing word extracting circuit Syn. Such a sync word also, incidentally, blocks a gate GS1 to prevent storage in the buffer of any sync words. The gate GU then enables a circuit ST to generate a signal blocking GS2 to cut off the clock TG from the decoding and output gating circuits of the buffer, Z in -D in -AG, the resulting time gap representing a blind bit or bits. GS2 also blocks output switching circuits K f , and inhibits a sync word generator S g  which normally counts the pulses from GS2 and after an appropriate number generates a sync word for the local frame, starting with a sync bit A i , this being also fed to K f . The GS2 output is also an input to the sync word generator S g , which controls production of the γ pulse at Z s .

[Also in Division F1] A poppet valve in an I.C. engine has a seating surface 23 on a ring 22 located in a recess, formed by walls 15 and 16, and a wall 17 on a collar 18, so that it can move both circumferentially and radially. A pin 21 locks the collar 18 against rotation. The ring 22 may be prevented from rotating circumferentially by a peg located in a slot formed in the ring.

Abstract: 550,963. Arylacetonitrile derivatives. ROCHE PRODUCTS, LTD., BERGEL, F., HINDLEY, N.C., MORRISON, A. L., and RINDERKNECHT, H. Aug. 12, 1941, No. 10249. [Class 2 (iii)]. α:α-Bis-(#<SP>1</SP>-halogenalkyl)-arylacetonitriles are prepared by condensing an arylacetonitrile in which the reactive methylene group is free with slightly more than two molecular proportions of a #-halogenalkylvinyl ether in presence of an alkali metal or compound (sodamide) capable of forming an alkali derivative of the arylacetonitrile, subjecting the product to mild hydrolysis with an acid reagent and treating the α:α- bis-(#<SP>1</SP>-hydroxyalkyl)-arylacetonitrile with a halogenating agent. Treatment with primary amines converts the halogen compounds to 4-arylpiperidine-4-nitriles which can be hydrolysed to acids, from which esters and amides can be. formed in known manner. In examples #-chloroethyl-vinyl ether and benzyl cyanide are condensed to αα-bis-(#<SP>1</SP>-vinylogy-ethyl)-α- phenylacetonitrile, which is converted to the #<SP>1</SP>-hydroxyethyl and thence to the #<SP>1</SP>-chloroethyl compound. Treatment of this with methylamine gives 1-methyl-4-phenylpiperidine- 4-nitrile which can be converted to the 4- carboxylic acid by concentrated HCl at 130‹C., and with benzylamine gives 1-benzyl-4-phenylpiperidine-4-nitrile. αα-Bis-(#<SP>1</SP>-chloroethyl)-α- (o-tolyl)-acetonitrile is prepared by the same steps from o-methylbenzyl cyanide, and converted to 1-methyl-4-(o-tolyl)-piperidine-4-nitrile and the 4-carboxylic acid.
