Title: Gyro horizon
IPC: G01C19/32
Filed: 1969-05-15
Abstract: 1, 247, 785. Gyroscopic apparatus. BODENSEEWERK GERATETECHNIK G. m. b. H. May 15, 1969 [June 8, 1968], No.24874/69. Heading G1C. An artificial horizon for a craft comprises a vertical gyro 16, the casing of which forms the pitch ring, the gyro being mounted for rotation at 17 about a pitch axis in a roll ring 18 itself mounted for rotation about a roll axis in journals 19, 20, and a part-spherical indicator shell 4 marked with a horizon line (not shown), the indicator shell 4 being pivotally supported at 44 for rotation about the pitch axis by an arm fixed to the roll ring 18 and also at 43 by an arm 22 carried by the journal 19 which extends through its bearing support, so that movement of the craft in roll relative to the gyro 16 causes rotation in the same sense of the indicator shell 4 about the roll axis, movements of the craft in pitch being transmitted to the indicator shell through reverse gearing 23 so that the indicator shell rotates in the opposite sense to the apparent rotation of the gyro thus giving a time indication of a dive or climb attitude of the craft. Balance weights 40, 41 balance the indicator shell 4 about the pitch axis and the areas of the indicator above and below the horizon line are preferably contrastingly shaded light and dark respectively. The indicator shell 4 is viewed through a barrel shaped aperture in a mask carried by the casing of the instrument (not shown) a stationary aircraft symbol being mounted in the aperture in front of the shell 4. The mask is manually rotatable about the roll axis to adjust and set the roll indication given, and the aircraft symbol is movable vertically to adjust the given pitch indication. The instrument also contains a ball level and a turn indicator visible through apertures in the mask. A shell 24 carried by the journal 19 is mounted so as to become visible if the rate of dive or climb of the craft is such as to bring the edge of the indicator shell 4 across the viewing aperture in the mask.

Title: Improvements in advertising apparatus
IPC: G09F21/04
Filed: 1952-10-06
Abstract: 720,238. Moving signs. GUEYDAN, A. Dec. 9, 1952, [Oct. 6, 1952], No. 24931/52. Class 3(1). Advertising apparatus of the kind in which vibrations, i.e. of a vehicle actuate a member carrying the advertisements, comprises in combination a flat casing having its front forming an advertising panel provided with a window and within which is located a rotatable disc carrying advertisements visible through the window, the disc being mounted on a horizontal axle, a driven member being coaxially fixed to the disc; a weight resiliently suspended and provided with an aperture through which the axle projects; and driving means constituted by hairy material, such as plush forming a gripping surface, or pivoted pawls, or convex blades, mounted either on the weight or on the driven-member so that the driven member is rotated unidirectionally when the weight is vibrated. As shown in Fig. 2 a disc 3 bearing advertisements is rotatable mounted on an axle 4 fixed in a casing 1, the front panel 2 of the casing having the window. A drum 5 is attached coaxially to the back of the disc and enters a circular aperture in a weight 7 which is suspended by a spring 8 and pivoted lever from the casing. The lever is adjustably positioned by means of a bolt 10 so that the position of the aperture relative to the drum 5 can be varied. The surface of the drum 5 is covered with a plush material the hairs of which are arranged substantially tangentially to its surface so that when the weight 7 is vibrated by movements of the vehicle the drum 5 and hence the disc 3 are given the unidirectional vibration. In a modification the member 7 has no aperture but is attached to a stirrup shaped element enclosing the drum. In another construction, Fig. 3, a spring supported weight 11 is constrained to move vertically by means of a slot 12 which engages the axle on which a disc 15 is mounted. The weight 11 has two strips 13, 14 of plush material mounted one on each side of the slot with the hairs arranged in opposite directions and these strips engage the surface of the disc 15 to cause it to rotate unidirectionally. In a modification of this construction the disc is rotated by pawls or convex blades on the weight 11 which engages a drum attached to the disc 15. The weight 11 may be guided by rollers or grooves in the casing of the device so as to move only vertically. Specifications 159,876, 205,905, [both in Class 3 (i)], are referred to.

Title: Improvements in or relating to the production of ethers of phenyl methyl carbinols and its homologues
IPC: C07C41/06
Filed: 1945-09-27
Abstract: Ethers of phenyl methyl carbonol and its homologues are produced by heating styrene or a homologue thereof with an alcohol in the presence of an acidic catalyst and in the presence of phenyl acetylene.  An additional relatively non-volatile polymerization inhibitor such as pyrogallol or hydroquinone may also be present. Particularly suitable alcohols are the higher monohydric alcohols boiling above 160 DEG  C., e.g. benzyl alcohol, beta-phenyl ethanol, n-hexyl alcohol and its homologues or a monohydric ether of a polyhydric alcohol and these may be suitably condensed with styrene or its homologues such as para-methylstyrene and vinyl xylene.  In examples, styrene is heated under reflux with benzyl alcohol, beta-phenyl-ethyl alcohol and ethylene glycol monobutyl ether respectively.  In each case, p-toluene sulphonic acid is used as catalyst and each reaction is effected using pyrogallol and phenylacetylene respectively as polymerization inhibitors, somewhat greater yields of the ether product being obtained with the latter. The products are benzyl alpha-methyl benzyl ether, beta-phenyl-ethyl alpha-methyl benzyl ether and butoxyethyl alpha-methyl benzyl ether respectively. Specification 517,934 is referred to. p

Title: Motor speed control system
IPC: H02P7/29
Filed: 1973-05-25
Abstract: 1426231 Automatic control of speed CANON KK 25 May 1973 [25 May 1972] 25281/73 Heading G3R The speed of a D.C. motor 1 is controlled by varying the duration of pulses produced in response to a speed error signal derived from a comparison made in differential amplifier 7 of the voltage generated by tacho-generator 2 and a temperature compensated reference voltage at point F. A switchable potential divider chain 10 allows the controlled speed of the motor to be changed. The error signal produced at the collector of transistor 45 in differential amplifier 7 is applied to the base of a further differential amplifier 5 so that the saw-tooth waveform generated by unijunction transistor oscillator 6 can be sampled to produce constant amplitude pulses whose width is proportional to the error signal. In alternative constructions a triangular or sine wave oscillator can be used. The motor is used to drive the film in a cine camera.
