Title: Instrument casings
IPC: G01D7/00
Filed: 1972-10-10
Abstract: 1360716 Thermometers; instrument casings DRESSER INDUSTRIES Inc 10 Oct 1972 [18 Oct 1971] 46656/72 Headings G1D, G1J and G1M A two-part casing of a measuring instrument, such as a thermometer, permits zeroizing thereof and comprises a metal sleeve 37 attached to one of the parts 12 and frictionally engaging the other of the parts 20, the two parts being rotatable relative to each other about a common axis against the friction provided by the sleeve 37. As shown, the instrument is in the form of a thermometer comprising a bi-metallic coil 11 attached at one end to the part 12 and at its other end to a rotatable shaft 17 which supports a pointer 27. The pointer 27 is moved due to the effects of temperature change sensed by the coil 11 over a scale 25 which is attached to the casing part 20 and viewed through a window 21 thereof. The casing part 12 which is of tubular form is provided with an outwardly extending flange 35 urged by a frusto-conical flange 40 of the sleeve 37 into engagement with a rim 34 of an aperture 33 provided in the back plate 32 of the casing part 20. A gasket 39 is located in a recess 38 between the sleeve 37 and the back plate 32. By overcoming the effects of friction, the two casing parts may be rotated relative to each other to adjust the position of the pointer 27 relative to the scale 25.

Title: Control system for a variable pump or motor
IPC: F04B49/08
Filed: 1974-10-29
Abstract: 1467706 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 29 Oct 1974 [14 Nov 1973] 46782/74 Heading G3P A variable displacement pump 10 is adjusted to the maximum delivery position shown by output pressure applied to a piston 15 from line 19 until the pressure is sufficient to displace a valve 32 from position II to position I to cause full output pressure to be applied to a second piston 16 through lines 21 and 31 to return the pump towards minimum displacement. A valve 27 coupled to the piston 16 is moved by the latter to regulate the pressure applied to piston 16 during control of the pump output by piston 15. A valve 26, operated before the valve 15, isolates a reservoir 29 from the valve 27. If fluid under pressure is supplied to a line 20, a valve 24 moves from seat 23 to 23' and the pump 10 functions as a motor with its displacement controlled in a similar manner.
Patent GB-1408059-A (GB)
Title: Liquid crystalline compositions exhibiting circular dichroism
IPC: C09K19/54
Filed: 1972-10-11
Abstract: 1408059 Liquid crystal compositions XEROX CORP 11 Oct 1972 [22 Oct 1971] 46896/72 Heading C4X [Also in Divisions H3-H5] The absorption bands of a material incorporated in a host cholesteric liquid crystal environment become circularly dichroic, irrespective of whether the material per se is optically active. The band of circular polarization preferentially absorbed is opposite to that which is preferentially reflected in the reflection band due to the cholesteric structure. The incorporated material may be nematic, smectic or non-mesomorphic, and may be more than one such material, e.g. three materials to provide absorption bands spanning the visible spectrum. Some materials, such as p-methoxybenzylidenep-n-butylaniline, which have a preference for an environment of a particular band, may alter the pitch, or reverse the band, of the cholesteric helix, whereby the magnitude or sense of the circular dichroism, and the wavelength or sense of the reflection band, are altered. The helix pitch may also be controlled by mixing at least two cholesteric host materials, e.g. of different pitch sense, such as cholesteryl chloride and cholesteryl nonanoate, in different ratios. Lists of suitable additive and cholesteric host materials are provided, together with examples of combinations thereof.

Patent GB-1014739-A (GB)
Title: Magnetic tape recorders
IPC: G11B5/55
Filed: 1963-11-28
Abstract: 1,014,739. Magnetic tape recording &c. apparatus. AKAI ELECTRIC CO. Ltd. Nov. 28, 1963 [Nov. 29, 1962], No. 47006/63. Heading G5R. A mechanism for automatic operation of a plurality of reciprocating playback or recording operations in a magnetic tape recorder provided with a capstan drive, comprises a pressure roller engageable with the capstan to drive the tape and disengageable therefrom to halt the tape, and a brake mechanism operating on the tape reeling mechanism for a short time at each tape drive reversing operation so that the capstan is relieved from load during a reversing operation until it recovers its steady tape feed speed in the revised sense. The tape is driven normally until a desired starting point is stopped adjacent to the head assembly. A dial 10, Fig. 2, is then rotated manually to bring its zero mark in registration with a stationary indicator 86. A setting knob 32 is rotated manually to bring an indicator mark on the knob into alignment with a number on the scale 11 corresponding to a desired reversal point, and a socket 59 is connected to an A.C. supply 60 to energize the capstan motor 64. When switch 85 is moved from its " stop " to its " play " position, the ganged switches 42 and 71 are closed. Switch 71 energizes the takeup reel motor 74 and the supply reel motor 78 (driven in the reverse direction to maintain tape tension) via a resistance 82. Closure of switch 62 allows a condenser 57 to charge through a relay 52, and the charging current opens contact 52a thereby de-energizing coils 54 and 55 and allowing brakes 91 and 92 to act on the supply and take-up reels and pressure roller 93 to be retracted from the capstan. When the condenser 57 has charged up, relay 52 is released, thereby releasing brakes 91 and 92 and causing the roller 93 to engage the tape. The dial 10 is driven (by means not shown in Fig. 2) at a highly reduced rate from the take-up reel drive, and when it has rotated by an amount corresponding to the setting of knob 32, contacts 33 and 34 meet and earth the point 35. This causes condenser 57 to discharge, thereby operating relay 52 to release the drive and apply the brakes; also current through relays 46 and 47 is now sufficient to operate them. Relay 47 reverses the rotation of capstan motor 66 via contacts 47a and 47b and, via contact 80, cuts out resistance 82, thereby increasing the torque of motor 78. Relay 46 maintains the earth at junction 50 via a closed switch 37. When the tape has been driven back to its initial position, a projection 38 on dial 10 opens switch 37, and forward drive is started again. Relays may be provided in parallel with relays 46 and 47 for moving the magnetic heads and changing-over amplifier connections, Fig. 4 (not shown). The apparatus may be used for stereo-recording, with a pair of tracks on the tape used for the forward drive and a second pair of tracks used for the reverse drive.

Title: Hydraulic tube testing press,more particularly for testing tubes of various diameters and thicknesses within a wide range of diameters
IPC: G01M3/28
Filed: 1964-11-18
Abstract: 1,091,243. Testing tubes. M. VON BUSHE and T. ALTENBRACHT [trading as TH. KIESERLING & ALBRECHT]. Nov.18, 1964 [Jan.22, 1964], No.47046/64. Heading G1S. In a hydraulic tube testing press, there is provided sealing head supports constructed as differential pistons and means for providing separate pressure medium cycles, in which a pressure regulator is provided by which a determined gripping pressure/test pressure ratio can be adjusted, which ratio is retained upon variation of the test pressure, and in which the differential piston is provided with three operating surfaces F1, F2, F3 of different dimensions for generation of the gripping forces and the pressure medium face for one of the test surfaces is in direct communication with the pressure medium used for producing the test pressure, the pressure medium spaces of the remaining two operating surfaces being each in communication therewith through a pressure-reducing valve and a servovalve, each servovalve being actuated by an associated piston to which the pressure medium used for producing the test pressure is admitted through lever means producing a determined variable mechanical advantage. In operation, the sealing heads 3a, 4a and pistons 3, 4 are advanced to grip the tube 5 by hydraulic means, the end of the tube being sealed by packings 6. A fill-up valve 12 is then opened and oil is admitted to the piston 9a of double-piston pressure converter 9 moving the piston to the left hand position, as in Fig. 1. Test water then flows through lines 13, 14, bores 15, 16, 17 and through a bore 19 to flush the tube 5. The pressureconverter 9 is moved the right as in Fig. 1 so as to apply a force, corresponding to the ratio of the lever arms 26, 26a, to the seat 25d of the valve cone of the respective servovalves 25, 25a. This pressure build-up is transmitted through lines 32, 41, 41a into the pressure medium Spaces F1a, F2a for the operating surfaces F1, F2 of the pistons 3, 4. The gripping pressure thus developed is limited by the position of valve seat 25d in valves 25, 25a. During testing, any drop in pressure due to leakage results in a pressure drop in line 60 causing differential pistoo 61 to actuate a limit switch 62 emitting an impulse to indicate a defective tube. Hydraulic circuit means are provided for reducing pressure in the tube and returning the sealing heads 3a, 4a to their original position.
