Title: Production of alcohols
IPC: C07C29/149
Filed: 1963-11-13
Abstract: Esters, including lactones, are converted to the corresponding monohydric or dihydric alcohols by reaction with hydrogen at elevated temperature and superatmospheric pressure in the presence of a copper hydrogenation catalyst comprising Raney copper or barium oxide-promoted copper chromite.  The esters may carry hydroxy or amino groups on the acyl portion of the molecule. Examples are given of the hydrogenation of (a) a mixture of 1,6-hexane diol esters of adipic and epsilon-hydroxy caproic acids to give 1,6-hexanediol; (b) ethyl pelargonate to give nonyl alcohol and (c) epsilon-caprolactone to give 1,6-hexane diol. Among other starting materials mentioned are butyrolactone, gamma-valerolactone, and hexyl (6-amino) caproate.

Abstract: 1320008 Piezoelectric crystals SUWA SEIKOSHA KK 21 Sept 1970 [3 Oct 1969] 44798/70 Heading H1E A crystal vibrator which may be used in a wrist-watch comprises a piezoelectric crystal tuning fork supported by two supporting springs which engage the base portion of the fork at points 30 on the nodal plane so as to reduce stresses in the base portion and energy losses. The two springs 28 are attached to rigid supports 24 and engage in holes in the base of the tuning fork where they are soldered. The supports 24 and springs 28 serve also to supply power to the fork and a further lead 25 is provided. To minimize the effects of the linear forces due to a shock the centre of gravity of the fork may be made to coincide with the centre of gyration of the fork prongs (see Specification 1,320,010). The ratio of minimum separation a of the prongs from the points of support 30 to the width d of the prongs in the plane of vibration is preferably between 3 and 6, when the Q factor of the resonator is insensitive to variations in the values of a and d. The crystal may be mounted in a hermetic container 31 which may be lined with resilient material 32 for protection of the ends of the prongs 20 (see Specification 1,320,009).

Title: Adjustable steering column employing memory unit
IPC: B62D1/184
Filed: 1966-10-10
Abstract: 1,129,679. Adjustable steering columns. BORG-WARNER CORP. 10 Oct., 1966 [26 Nov., 1965], No. 45117/66. Heading B7H. In a motor vehicle steering column assembly comprising an upper column section tiltable with respect to a lower column section, locking means for positioning the upper column section in a plurality of positions is associated with a preselector device for ensuring that the upper section locks only in a preselected position. A fixed lower column 12 housing a lower steering shaft 14 carries a V-bracket 38 on which an upper. column 18 supporting an upper steering shaft 16 is tiltably mounted by pivot pins 66, 68 aligned with a universal joint 24 coupling the shafts 14, 16. A pawl 100 secured to a spindle 102 rotatably mounted in the upper column 18 is urged by a spring into engagement with a toothed extremity 60 of the V-bracket 38 to position the upper column 18 in a plurality of angular positions. The pawl 100 is disengaged from the teeth to permit adjustment of the upper column 18 by pivoting a control lever 94 which engages an actuating arm 104 on the spindle 102. To facilitate return of the upper column 18 to a previously selected position after adjustment to suit another driver or to assist entry or exit from the vehicle, a blocking pawl 116 attached to the pawl 100 co-operates with an indexing plate 122 to prevent the pawl 100 from engaging the toothed portion 60 other than in the preselected position. Each of a series of indexing slots in the periphery of the indexing plate engages with a tooth 120 on the blocking pawl 116 to permit positioning of the upper column only in one position. The desired position is preselected by a selector knob 126 which is first displaced axially against spring-loading to disengage the indexing plate 122 from the blocking pawl 116 and from a fixed pin 63 engaging a series of indexing holes in the plate, and is then rotated to position the plate in the desired position as indicated by an indexing drum 134 which is connected to rotate with the knob 126 by spring- loaded pins 138 and displays through an aperture in a housing 150 a series of numbers indicating the position of the indexing plate 122. A second series of slots associated with the indexing slots in the plate 122 provide for lock. ing the upper column portion 18 in an extreme raised position whatever the preselected position, and unrestricted adjustment is obtainable by positioning the indexing plate 122 so that none of the indexing holes therein engage the pin 63.

In V.L.F. radio frequency-shift telegraphy an antenna is automatically tuned into resonance with the keyed frequency by detecting, during mis-tuning, phase shift between the input and output of a power amplifier feeding the antenna as a D.C. error voltage which varies reactance in the antenna to restore resonance. As shown, the phase detector may be a multi-grid tube V2 with inputs from P.A. tube V1, normally in phase quadrature due to 90 degree phase-shift network C1, R3, and its amplified output is applied to a coil 9, 10 energizing an electromagnet E whose flux varies a ferrite core inductance B2 series connected with the antenna. Alternatively, the amplified phase detector output may vary the resistive impedance of a triode in series with a capacitor shunting a portion of the antenna inductance, Fig. 3 (not shown).
