Title: Variable resistance potentiometers
IPC: H01C17/065
Filed: 1964-01-29
Abstract: 1,002,048. Coating surfaces. FAIRCHlLD CAMERA & INSTRUMENT CORPORATION. Jan. 29, 1964 [March 11, 1963], No. 3760/64. Heading B2B. [Also in Division H1] A variable resistance track of a potentiometer is made by spraying a resistance material on to an insulating base while moving the base along a predetermined path and simultaneously varying the amount of spray so that the track is of different depth at different points along its length. In Fig. 1 an . insulating base 16 is rotated at constant speed and a suspension of carbon in a mixture of thermosetting polyester and benzene is sprayed through aperture 14 in masking plate 10 to form track 20. A cam 22 rotates between the plate 10 and base 16 and the effect of the cam is to alter the height of the orifice 14 so that the depth of the deposited track varies. In Fig. 3 a helical conductive track is deposited on a cylindrical base 55 which is rotated through gearing 46, 49 by motor 43. Spray gun 30, masking plate 61, and spray throttling cam 60, driven through gearing 38, 40 and shaft 59, are all attached to plate 28 which is moved upwards and downwards through nut 31 by turning of screw 74. The depth of the track is varied in the apparatus of Fig. 8 by varying the speed at which the base element 101 is rotated through shaft 106 by servomotor 107. Also attached to shaft 106 is cam 111 which contacts roller 112 on a hinged arm which acts on variable resistance 116 which by means of servoamplifier 120 controls the speed of motor 107. After forming the track, the base is moulded at raised temperature and pressure so that the track is flush with the base surface.

Title: Process for the production of 2-methyl-butanol-(1)-one(3)
Filed: 1955-02-09
Abstract: 2-methyl-butanol-1-one-3 is prepared by condensing methyl ethyl ketone with formaldehyde in an aqueous alkaline medium at a temperature in the range 50-100 DEG  C., using 2-10 mols. of methyl ethyl ketone per mol. of formaldehyde and continuously or intermittently adding alkali throughout the course of the reaction at such a rate that the reaction proceeds smoothly to completion preferably in 15-40 minutes.  Advantageously, the addition of alkali is controlled to maintain a substantially constant pH, preferably pH 8-12, in the reaction mixture.  The reacted mixture is acidified and then distilled to recover excess methyl ethyl ketone and water.  The process may be operated continuously.  In an example, methyl ethyl ketone (6 mols.) is heated with aqueous formaldehyde to 70 DEG  C. and aqueous NaOH added to maintain a pH of 9.1.  Distillation of the reacted product gives in addition to the desired keto-alcohol, a lesser amount of 3:3-dimethylol-butanone-2.

Abstract: 808,402. Thermal switches. STEVENS MANUFACTURING CO. Inc. Feb. 5, 1957, No. 3948/57. Class 38 (5). In a thermostat having an operating temperature adjusting screw 38 which also acts as an "on-off" switch, a resilient detent 51 mounted on the base 12 co-operates with a bar 47 on the adjusting screw to provide tactile indication of the " off " position. In the " off " position as shown, the bar 47 abuts a stop 57 on the nut 36 carrying the adjusting screw and a porcelain tip 39 on the adjusting screw holds the contacts 27, 28 apart. When the adjusting screw, which has a left-hand thread, is turned clockwise to a position corresponding to the required operating temperature, the bar 47 moves past the detent 51 and the tip 39 retracts to allow the contacts to close. As the bi-metallic strip 16 moves the contact strip 14 carrying the contact 27, the contact 28 follows it until at the operating temperature the contact strip 15 carrying the contact 28 abuts the tip 39 and the contacts are opened.

Class 8(2) A pneumatic motor comprises a first chamber 11 connected to a source of pressure through a duct 6, throttle 5, duct 4 and a valve 36. A spring loaded piston valve 20 is subjected on one face 8 to the pressure in the chamber 11 and a predetermined pressure therein opens communication between the duct 4 and a port 18 which communicates with the chamber 11 through a throttle 21. A further rise in pressure causes the valve 20 to put a port 16 in communication with a port 2 open to atmosphere; the port 16 is connected through a duct 23, a valve 40 and a duct 24 with the second chamber 15, which is thus vented to atmosphere. The valves 36, 40 are pneumatically actuated under the control of a valve 25 to raise or lower the motor piston.

Abstract: 1373902 Hydraulic power steering etc. ROBERT BOSCH GmbH 26 Jan 1973 [25 Feb 1972] 4095/73 Heading B7H An hydraulic system for actuating a power steering unit and an air conditioning unit of a vehicle includes at least one engine driven pump which supplies pressure fluid to the power steering cylinder 10 and to a hydrostatic motor 19 which operates the compressor (not shown); of the air conditioning unit. In a first embodiment (Fig. 1) a pump 1 driven by engine 2 has two outlet ports 3, 4. Port 3 supplies the power steering cylinder 10 via line 6 and three-way steering valve 7 and port 4 supplies the motor 19 which drives the air conditioning compressor. Pressure relief valves 13, 20, valve 7 and motor 19 are all connected to a common return line 14. The pump 1 is of the variable type and the output at port 4 is controlled by control element 5 which is actuated by flow regulating valve 24 so that the motor 19 operates at constant rotational speed. Motor 19 can be stopped by opening a by-pass valve 23. In a second embodiment (Fig. 2), a single variable pump 28 supplies pressure fluid to a three-way steering valve 30. In the neutral steering position II as shown valve 30 supplies fluid to motor 19. In the operative steering positions I and III valve 30 supplies fluid to cylinder 10, and a flow regulating valve 38 and by-pass line 39 supplies the motor 19. Again a flow regulating valve 34 actuates pump control elements 37 so that motor 19 operates at a constant rotational speed. In a third embodiment (not shown), the output of the pump 28 is controlled by a control valve connected to the three-way valve. The control valve has a slide which is biased on one side by the delivery pressure of the pump and on the other side by a spring and a pressure which is lower than the delivery pressure by the amount of pressure drop across at least one throttle disposed in the three-way valve. In other embodiments (not shown), two variable pumps are provided. The steering cylinder 10 and motor 19 may be supplied by separate pumps or may be supplied together by the combined output of the two pumps. Again flow regulating arrangements are provided to vary the outputs of one and/or both pumps so that motor 19 operates at constant rotational speed and so that cylinder 10 has an adequate supply of pressure fluid when required.
