Title: Resistance networks with thermistors
IPC: H01C7/04
Filed: 1961-07-17
Abstract: 937,593. Resistance networks. E. TAKAGISHI. July 17, 1961, No. 25775/61. Drawings to Specification. Class 40 (8). A resistance network including series and parallel resistors, e.g. in T or # form, and a thermistor across its output terminals, has different input impedances at three different temperatures independent of the deviation of the thermistor from its rated values at these temperatures. The Specification, which does not admit of satisfactory abridgment, sets forth in detail the criteria for choosing the values of the resistors and gives numerical examples. The three temperatures may be regarded as defining sectors of a temperature characteristic curve over which sector the network may be presumed to have an impedance independent of the deviation of the thermistor.

Title: Optical observation instrument with photometer
IPC: G02B21/00
Filed: 1961-07-18
Abstract: 925,726. Photo-electric photometers. CARL ZEISS-STIFTUNG, [trading as C. ZEISS [Firm of]]. July 18, 1961 [July 29, 1960], No. 25915/61. Class 40 (3). [Also in Group XX] A microscope has a photo-cell 9 mounted on an extension from the objective holder 3 thereof so as to transmit to a meter successive signals corresponding to the absorption of a specimen object mounted on a stage 4 and to a standard object 14 carried by a holder 13 supported rotatively on the objective holder 3. The stage 4 is adjustable toward and away from the objective by a knob 5 to which may be coupled a releasable member 16 having a handle 17 and coupled by a lever system 15b, 15a to a disc 12 forming part of the holder for the standard object. When the knob 5 is coupled to the member 16 rotation of the knob moves the stage 4 away from the objective and simultaneously brings the standard object 14 into the light path through said lens. In use the stage is first moved until it is sharply focused by the objective. The handle 17 is then abutted with an element 19 on the microscope casing and screws 20, 21 and 22 are tightened so that knob 5 is operatively connected to the member 16. Knob 5 is then rotated counter-clockwise so that the handle 17 abuts the base 1 of the microscope, such movement causing the standard 14 to be moved into the space left between the objective and the stage 4. After observing the meter reading, the knob 5 is then rotated clockwise until the handle 17 abuts the element 19 and a further reading is then taken with the specimen object on the stage 4 in its focused position. Instead of coupling the adjusting knob with a holder for the standard object 14 by means of a pivoted lever system the coupling may be effected by a rotary electromagnet (Figs. 3 and 4, not shown).

Abstract: 319,479. Siemens -Schuckertwerke Akt.-Ges., and Dieterlen, M. Sept. 10, 1928. Dynamos and motors, cooling and ventilating.- In a cooling arrangement for open-type machines having an open-circuit cooling air path, the air is admitted freely to the spaces between the rotor coil ends and the rotor shaft at both ends of the machine while the spaces between the coil ends and the stator edge are covered so as to form enclosed chambers, and at least one fan is mounted on the shaft with its suction side communicating with the enclosed chambers to lower the pressure therein. In the form shown in Fig. 1, the fans are mounted on the enclosing discs 11, 12 which are mounted on the bindings of the projecting ends of the rotor windings and extend outwards to the edges 13 of the stator. The fans draw air through ducts 5 and 7 in the commutator and rotor hubs and through the ventilating ducts 8 in the rotor iron, this air being directly expelled without passing over the stator structure. Air is also drawn in through central openings 16 in the stator and is expelled with that from the rotor. Fig. 2 shows a double-commutator machine in which the fan wheels 11, 12 are mounted on the commutators with intervening insulation 18 with their blades 19 at substantially the same radius as the machine air-gap so that the warm air current from one member of the machine cannot reach the other member. The spaces between the outer edges of the fan wheels and the edges of the stator are closed by shields 22 with guide walls 21 for directing the emerging air as shown by the arrows.

Title: Production and isolation of boron trichloride
IPC: C01B35/06
Filed: 1958-08-14
Abstract: Boron trichloride is isolated from gaseous mixtures containing it together with carbon monoxide or carbon monoxide and carbon dioxide and obtained by the interaction of chlorine, carbon and boric oxide or alkali metal or alkaline earth metal borates, by contacting the mixtures with a liquid organic solvent consisting essentially of one or more fluorinated and/or chlorinated hydrocarbons of the aliphatic series containing at least two halogen atoms per molecule and having from 2 to 12 carbon atoms in the molecule or of the aromatic series having either a single benzene ring or two unfused benzene rings in the molecule, separating the resulting liquid solution containing absorbed boron trichloride from the undissolved gas and recovering boron trichloride from the separated solution by increasing the temperature and/or reducing the pressure.  The gaseous mixtures containing boron trichloride are contacted in a packed column in counter-current with an organic solvent, e.g. dichlorobenzene, fluorochlorobenzene, tetrachloroethane, pentachloroethane or dichloropentane, preferably a chlorinated diphenyl, trichlorobenzene, or difluorotetrachloroethane.  The conditions of absorption are dependant upon the solvent employed but generally the lowest possible temperature consistent with the proper fluidity of the solvent and pressures of up to 10-15 atmospheres are employed.  The solution of boron trichloride leaving the packed column is fed to a distillation column to release dissolved boron trichloride.  Distillation may be under reduced pressure, e.g. 1/2 -\ba1/10th atmosphere or lower, at temperatures selected to give minimum practicable solubility of boron trichloride in the solvent and to avoid reaction of the boron trichloride therewith.
