Abstract: 1,141,664. Piperidine derivatives. JANSSEN PHARMACEUTICA N.V. 7 Dec., 1966 [8 Dec., 1965; 23 Sept., 1966], Nos. 52125/65 and 42589/66. Heading C2C. Novel piperidine derivatives having the general formula wherein Y is Ar or Ar<SP>3</SP> and Z is Ar<SP>1</SP> or Ar<SP>2</SP> ,  Ar being phenyl, halophenyl or lower alkoxy phenyl, Ar<SP>1</SP> being dihalophenyl, trihalophenyl, lower alkyl-halophenyl or trifluoromethyl-halophenyl, Ar<SP>2</SP> being halophenyl and Ar<SP>3</SP> being dihalophenyl or lower alkyl-halophenyl, with the proviso that when Y is Ar then Z is Ar<SP>1</SP> and when Y is Ar<SP>3</SP> then Z is Ar<SP>2</SP>, and their pharmaceutically acceptable acid addition salts and quaternary ammonium compounds may be prepared either by condensing a reactive ester of a compound of the formula with a compound of the formula (IV) in a suitable solvent or by reacting a reactive ester of a compound of the formula with a compound of Formula IV to prepare a compound of the formula which is then reacted under Grignard conditions with a compound Y-Mg-Halogen. Compounds of the Formula IV are prepared either by condensing a compound of Formula V wherein R is benzyl or alkoxy-carbonyl with a compound ZLi to give a compound of formula which is converted by water to the corresponding hydroxy compound after which the protecting group R is removed or reacting a compound of Formula V with Z-Mg-Halogen under Grignard conditions to give the hydroxy compound as above from which the protecting group R is then removed. Removal of R is by hydrogenation if R is benzyl or by treatment with alkali if R is alkoxy carbonyl. Intermediates prepared in examples are 1 - (3 - cyanopropyl) - 4 - hydroxy - 4 - (4 - chlorophenyl) piperidine, 1 - (ethoxycarbonyl) - 4 - hydroxy - 4 - (3 - chloro - 4 - methylphenyl) - piperidine. 1 - (ethoxy carbonyl) - 4 - hydroxy - 4 - (3 ,4 - dichlorophenyl) - -piperidine, 1 - (ethoxy - carbonyl) - 4 - hydroxy - 4 - (3 - methyl - 4 - chlorophenyl) - piperidine, 1 - (ethoxycarbonyl) - 4 - hydroxy - 4 - (3 - trifluoromethyl - 4 - chlorophenyl) - piperidine and 4 - hydroxy - 4 - (3 - trifluoro - methyl - 4 - chlorophenyl) - piperidine and 1 - (ethoxycarbonyl) - 4 - hydroxy - 4 - (3,4,5 - trichlorophenyl) - piperidine and 4 - hydroicy - 4 - (3,4,5 - trichlorophenyl) - piperidine.

Title: A control circuit for a heater for the protection of a railway switch points against the deposition of snow or ice
IPC: G05D27/02
Filed: 1970-11-05
Abstract: 1300454 Detecting ice and snow; electrically TECHNISCH BUREAU W SEIBERT & CO N V 5 Nov 1970 [5 Nov 1969] 52633/70 Heading G1N [Also in Divisions F4 and H3] Apparatus for the protection of a railway switch or points against the deposition of snow or ice (Division F3-4) comprises a control circuit, Fig. 1, for a railway switch or points heater, the control circuit being responsive to the temperature of the switch from a temperature sensor VI and to the presence of humidity. In operation, the heater is controlled by a humidity sensor V3 which is normally at the ambient temperature but is periodically heated to a temperature such that any snow or ice deposited on sensor V3 is melted. When the temperature of the switch drops below a predetermined value of some degrees above freezing point, such as 3‹C., the sensor V1 causes a bi-stable trigger B1, Fig. 2 (not shown) to change state and switch on the humidity sensor V3. If humidity is detected, a bi-stable trigger B2 changes state, operating an electromagnetic valve between terminals K3 and K4 to initiate fuel supply of oil or gas for the switch heater, and actuating a timing switch including unijunction transistor U3 to generate ignition impulses between terminals K5 and K6 from transformer TR for the switch heater at short intervals such as 10 seconds. A timing switch including unijunction transistor U1 periodically actuates the heating of humidity sensor V3 by heating element W2, the heating being ended by another timing switch including unijunction transistor U2. The timing switch including transistor U1 has a cycle of 15-20 minutes in the absence of humidity which is considerably shortened if humidity is detected by a second humidity sensor V2 which is permanently heated by heating element W1. To extend the period of heating, a relay S may be incorporated to maintain heating until the said predetermined temperature value is reached. The form of the humidity sensors is shown in Figs. 3 and 4 in which E1 and E2 denote electrodes, IR denotes an insulating ring, W denotes heating elements and Y denotes perforations in E1 for the admission of water.

Title: Device for controlling the absorption of one or more components contained in a dye fluid
IPC: D06B23/28
Filed: 1973-11-29
Abstract: 1417875 Photo-electric measurement of concentration ORIGINAL HANAU QUARZLAMPEN GmbH 29 Nov 1973 [13 Dec 1972] 55450/73 Heading G1A A device for bringing a dye vat to the optimum temperature for absorption of one or more dye components comprises a photo-electric receiver for receiving a light beam transmitted by the dye fluid; a potential divider and a sample-and-hold circuit both responsive to the receiver output; a comparator for comparing the outputs of the potential divider and of the sample-and-hold circuit; and temperature-regulating means responsive to the  comparator output. A stabilized light source 18 illuminates a transparent tube 16 containing dye fluid circulating from a vat 10. The transparency of the dye, indicating the amount of absorption of one or more dye components by articles immersed in the vat 10, is sensed by a photo-cell 24 and amplified logarithmically at 26, providing an output linearly related to the absorption and indicated by a meter 34. Required signal outputs at the beginning and end of the absorption of any dye component are adjustable by resistors 28, 32. The amplifier 26 output is periodically sampled by a switch 36 operated by a relay 38 driven by a narrow clockpulse generator 68 adjustable in frequency by a resistor 70, the sampled output being held by a capacitor 44 and applied via a unitygain buffer 46 to one input of a comparator 48. The other input receives an adjustable. fraction of the amplifier output from the potentiometer wiper 50. As long as the sample held on the capacitor 44 exceeds the divided potential at 50 the comparator 48, via an adjustable delay 52 and a relay 56, 58, causes heat to be supplied to the vat 10 via a heating/cooling valve system 60. Any increase in amplifier 26 output rapid enough to cause the fractional potential at 50 to exceed the sampled output at 44 during any holding period causes abrupt reversal of the comparator 48 output with consequent interruption of the heat supply. Absorption of a first dye component from an initially cold fluid is slow, and so the device initially maintains a continuous heat supply. As absorption accelerates, the consequent rate of rise of transparency increases to a point where the comparator 48 periodically interrupts the heat supply; any subsequent decline in absorption results in restoration of the heat, with consequent stabilization of the temperature of the optimum. When substantially all the first dye component is absorbed the rate of increase of transparency slackens; continuous heat is thus turned on again until a new optimum temperature for absorption of a second dye component is attained; and so on.
