Title: Improvements in Temperature-Controlled Flow Control Devices
IPC: F25B41/06
Filed: 1966-11-07
Abstract: 1,152,350. Valves. CONTROLS CO. OF AMERICA. 7 Nov., 1966 [10 Feb., 1966], No. 49751/66. Heading F2V. [Also in Division F4] The flow of refrigerant to an evaporator is controlled by the valve member 44. A datum flow is set by the controlled heating of a bimetallic member 56 through an electric heating element 60 and variable resistor (78), Fig. 1 (not shown). Member 56 acts against a biasing spring 68. In operation the valve is further controlled by refrigerant leaving the evaporator and communicating through a connection 80 with a chamber 85 which houses the bimetallic member so that the cooling effect of any liquid refrigerant entering this chamber tends to close the valve rapidly. Transient effects or hunting are avoided by a gauze 86 in the connection 80. In the event of overload the evaporator outlet pressure communicated through chamber 85 and passage 100 to a bellows 96 opens a by-pass valve 92 allowing liquid refrigerant from the main valve chamber to enter the chamber 85 and effect shut-down owing to rapid cooling.

Title: Improvements in and relating to new synthetic polyester resins
Inventor: PAJOT PIERRE THEODORE CAMILIE
IPC: C09D167/08
Filed: 1964-12-28
Abstract: Polyesters are obtained by condensing a polycarboxylic acid and a polyhydric alcohol with a branched aliphatic monocarboxylic acid having the acid group attached directly to a -CH2- group. Suitable acids of the latter type are obtained by oxidation of the "ketoaldehydes" obtained by hydroformylation of an olefine, e.g. a mixture of 3- and 5-methyl-hexanoic acid with a small amount of 2,4-dimethylpentanoic acid derived in this way from 2-methyl-1-pentene.  Other suitable acids or mixtures may be derived from propylene trimers and tetramers and co-dimers of propylene and butylene.  In examples these are condensed with phthalic anhydride and with ethylene glycol, glycerol, pentaerythritol, and trimethylolpropane, or mixtures of these, to give polyesters, benzoic acid also being added in Example 5. These polyesters may be mixed with aminoplasts, e.g. butylated MF or VF resins, or with phenoplast resins, and with a pigment, e.g. TiO2 to give enamels.  The components of the polyester may be condensed simultaneously, or a part of the monacid may be precondensed with the polyol, or the bulk of the monacid may be added after a part of it has been condensed with the polycarboxylic acid and the polyol.ALSO:Thin steel plates are coated with an enamel composition comprising an aminoplast resin, a polyester derived from a polycarboxylic acid, a polyol and a branched aliphatic moncarboxylic acid containing a -CH2COOH group, and a pigment.  Used in the Examples are butylated urea- or melamine-formaldehyde resins, TiO2 and polyesters derived from phthalic anhydride, a polyol, and acids obtained by p  formylation and oxidation of 2-methyl-1-pentene, propylene trimer or tetramer, propylene/butylene codimer, and optionally benzoic acid.

Abstract: 1,147,440. Transistor pulse circuits; data transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 1 Dec., 1966 [20 Dec., 1965], No. 53748/66. Headings H3T and H4P. An arrangement for connection between a digital transmitter at S/D and a line 11 comprises an output saturable transformer 10 and driver circuit as shown. When a transition occurs in the digital data input, transistors 13, 14 change state so reversing the state of saturation in transformer 15. The collector current of transistor 14 is greater than that of 13. Resistor 25 and diode 26 supply current, when transistor 14 is conducting, to make the load current approximately equal during 1 and 0 conditions. The pulse developed in winding 15c is clamped to a predetermined level by means of diodes 18, 19 and transistor 20, the latter components being arranged so that temperature variations have no effect. The transformer and the clamping level together determine the duration of the pulse supplied to transistor 21. This transistor feeds the primary of the output transformer 10, which provides balanced signals to the line 11. The circuit is such that other similar circuits may be connected to the line, transmission by any one circuit having substantially no effect on the others. Pulses received on a second line pass via transformer 30 and a low-pass filter (31, 32, 33) to a latching circuit comprising transistors 34, 35, power-driver transistor 36 providing output pulses at R/D.

Filed: 1973-11-20
Abstract: 1405225 Cow milking preparation stall BABSON BROS CO 20 Nov 1973 53889/73 Heading AIM In a stall 10, for automatically preparing cows for milking, spray nozzles 62 direct a cleaning solution followed by a rinsing solution onto a cow's udder. The cow enters the stall through two rear gates 22 which are closed by the action of a power operator 34 when the cow nudges a wand 70 of a switch 66. This also results in cleansing solution being sprayed at the udder, for a fixed time, from three rows of spray nozzles 62, which is followed again for a fixed time by a rinsewater spray. The front gates 20 are opened inwardly by a power operator 32 under the manual control of a parlour operator. On leaving the stall the cow trips a wand 68 of a switch 64 which results in the front gates 20 closing and the rear gates 22 opening. A feeding trough 140 is attached on the inside of one of the front gates 20 so that when the front gates 20 open the trough 140 will be moved beneath the lowermost tube of the side wall 12, and hence away from the animal. The dispensing of the feed from a hopper 150 is under timed control, to coincide with the arrival of a cow in the stall. An electrical circuit may be provided to render the stall automatic, but this can be overridden by the operator.

Abstract: 1,179,940. Radio navigation. DECCA Ltd. 10 Oct., 1968 [4 Dec., 1967], No. 55110/67. Heading H4D. Relates to a hyperbolic radio navigation system in which a master station and slave stations transmit on different frequencies simultaneously ("normal transmissions") for periods interspersed with periods (" multi-frequency transmissions ") in one of which the master station only transmits and transmits on all the frequencies, in the next of which one slave station only transmits and transmits on all frequencies and so on. According to the invention a receiver has channels 11, 12 tuned to radiated frequencies which differ by a frequency F, e.g. 6F, 5F, an oscillator 14 phase locked to a normal 6F transmission with phase stability over a short signal interruption, a divider 15 producing a reference signal of frequency F, a mixer 18 to afford a beat signal of frequency F, and a phase discriminator 17: when switch 19 is in position 19b the multi-frequency transmission from a slave station yields a " fine " position line determination and when in position 19a the multifrequency transmission from the same slave station yields a " coarse " position line determination. By similar measurements on transmissions from other slave stations further position lines are determined.
