Title: Improvements in or relating to surveying apparatus
IPC: G01C7/04
Filed: 1948-05-21
Abstract: 653,349. Recording-clinometers. DAFNOMILI, J. A. May 21, 1948, No. 13813. [Class 97 (ii)] In a surveying apparatus comprising a carriage adapted to be moved over the ground to be surveyed and having means for recording the deviations of the carriage from a horizontal plane in the direction of movement of the carriage, the resolution and recording of the deviations of the carriage are controlled from the free rotation of a disc around the internal surface of a stationary cylinder. As shown, a rotatable disc 7, coupled for driving engagement with one of the road-wheels of the vehicle, is in driving engagement with a pair of discs 8, 9, each of which is mounted on a shaft carrying a second disc 11, 15 of larger diameter and in the form of a frustum of a cone, the edge of each of the latter being in frictional driving engagement with a pair of cones 12, 13 and 16, 17 mounted for rotation about their geometric axes and so arranged relative to one another and their associated driving disc that their apices meet on the axis of the disc and their surfaces sub-tend to an angle of 180 degrees along a line parallel to the plane of the disc and at right angles to its axis. A pair of longitudinallygrooved cylinders 21, 22 arranged with their axes at right angles to each other and in the same plane and parallel with their associated disc 11, 15 are driven from the two pairs of cones by means of a pair of toothed discs 20, 23, each of which engages one cylinder and the surface of either one of one pair of cones. The shafts 31, 32 of the two toothed discs 20, 23 are connected to diametrically opposite points on a disc 33 free to rotate around the internal surface of a stationary cylinder 34 having a diameter twice that of the rotatable disc 33 and the other end of one shaft 32 is connected to a point on the periphery of a relatively heavy cylindrical member 35 having a diameter equal to that of the rotatable disc 33 and free to rotate around the internal surface of a control cylinder 36 having a diameter equal to that of the stationary cylinder 34. The control cylinder 36 is mounted in the vehicle in such a manner that it is maintained with its axis horizontal by the weight of the heavy member 35, the arrangement being such that, as the two pairs of cones are rotated at a speed proportional to the linear speed of the vehicle and the toothed discs 20, 23 are adjusted to their respective pair of cones 12, 13 and 16, 17 according to the inclination of the vehicle, the drive transmitted to the cylinders 21, 22 is proportional to the rectangular components of the vehicle's motion. These rectangular components of motion are transmitted from the cylinders 21, 22 to the recording stylus 26 by a pinion 24 and rod 25 and by a rack-and-pinion 29, rod 28 and rod 25 respectively.

Title: Improvements in folding mechanism
IPC: B65H45/16
Filed: 1923-05-25
Abstract: 218,451. Hoe & Co., Ltd., R., (Hoe & Co., R.). May 25, 1923. Folding paper. - Paper-lolding mechanism comprises in combination a rotary carrier operable at different speeds, sheet holding devices thereon such as pins, folding mechanism such as a tucking blade co-operating with folding rollers, and means for effecting automatically a relative change between the sheet path and the folding mechanism to cause successive sheets to be folded at the same point irrespective of their speed. The rotary carrier 7, which may co-operate with a cutting cylinder 5, carries folding blades, such as 15, operable in the usual manner to fold the sheets between the folding rollers 16, 17. When the mechanism is running at high speed the line of fold becomes displaced towards the rear end of the sheet, and when at very low speed towards the front end. This variation of the fold line is prevented by forming the carrier 7 with flats 18, 19 to the rear of the sheet holding pins 13, 14, through which flat fingers 20, 21 project more or less according to the speed of the carrier so that the effective diameter of the carrier at these positions is increased or decreased automatically according as the carrier runs at low or high speed. The shanks of the fingers 20, 21 are secured to rock shafts 23 provided with arms 25 carrying weights 26. Any increase of speed of the carrier 7 causes the weights 26 to move. outwardly against the pressure of springs 29, thereby moving the fingers 20, 21 inwardly.

Title: Engine starting mechanism
IPC: F02N5/04
Filed: 1940-09-10
Abstract: 543,780. Turning gear. BENDIX AVIATION CORPORATION. Sept. 10, 1940, No. 14051. Convention date, Sept. 26, 1939. [Class 7 (v)]  An electric motor 10 or other prime mover, having first run a flywheel 22 up to speed, is reversed, and thereafter, supplemented by the energy from the flywheel, transmits its motion to the engine-shaft 66, Bevel and planetary gearing 16, 18, 27, 26 connect the motorshaft 10 to the flywheel, which is restricted to one-way movement by a ratchet coupling 31. The spider 59, supporting the planet-wheels 27 is keyed to a shaft 58 which through double epicyclic gearing transmits movement to a barrel 43 enclosing a slipping clutch 69 and screw-and-nut members 71, 74. The member 71 is formed with the clutch member 64, companion to the engine-shaft member 66. Having set the flywheel 22 in motion, the current through the field-coils of the motor is reversed. The internally toothed ring 18 is brought first to rest and then caused to rotate in the opposite direction. The planetary support 59 rotates at an increasing speed due both to the motor 10 and the flywheel which, however, gradually comes to rest ; and the motor alone transmits to the engine at a constant speed dependent on the gear ratios. Movement of the support 59 is accompanied by sliding of the nut 71 and clutch member 64 producing engagement with the member 65 at zero speed. An electro-magnetically-operated brake, coming into use as the motor field-windings are altered, may be used to expedite reversal of the motor. Specification 345,018 is referred to.

[Class 2 (iii)] Ketones of the cyclopentanophenanthrene series are obtained from acetylene derivatives of this series by treating the acetylene compounds with a mercury salt of an acid amide if required in the presence of a suitable diluent or solvent, and decomposing the organomercury compound so produced by means of a strong acid or by means of hydrogen sulphide or a salt thereof. The acid amides may be either carboxylic or sulphonic acid amides. The sulphide method of decomposition is used when the process has to be conducted cautiously. In examples (1) #<SP>5</SP>-17-ethinylandrostene-3 : 17-diol is heated with mercury acetamide in ethyl alcohol solution. The mercury addition compound is decomposed by passing in hydrogen sulphide and the mercury sulphide removed by filtration. Purification of the residue by a chromatographic process yields # <SP>5</SP> : <SP>16</SP>-pregnadiene-3-ol-20-one. (2) # 5- 17-ethinyl-androstene-3 : 17-diol is re-acted with mercury acetamide as in example (1). The product is decomposed with sodium sulphide and worked up as before to give # <SP>5</SP> : <SP>16</SP>-pregnadiene-3-ol-20-one. (3) #<SP>4</SP>-17-ethinyl-androstene-3-one-17-ol is treated with mercury acetamide as in example (1), the product decomposed with sodium sulphide and worked up as before to give #<SP>4</SP> : <SP>16</SP>-pregnadiene-3 : 20- dione. Samples have been furnisned under Sect. 2 (5) of compounds prepared by (1) re-acting # <SP>5</SP>- 17-etbinyl androstene-3 : 17-diol with mercury p-toluene sulphamide in alcohol solution, and the product decomposed with hydrogen sulphide to give # <SP>5</SP>-pregnene-3 : 17 (α)-diol-20-one. (2) 17-Ethinyl testosterone is re-acted with mercury p-toluene sulphamide in alconol solution and the product decomposed with sodium sulphide to give 17 (α)-hydroxyprogesterone.

Filed: 1974-04-02
Abstract: 1455803 Stays ETABS GEORGES KLEIN 2 April 1974 [3 April 1973 20 Dec 1972] 14510/74 Heading E2F In a telescopic stay for windows or other movable structures, comprising two relatively telescopically displaceable members 3, 4, a cam surface 10 is provided on one member 3 which co-operates with a slidable locking member 7 to lock the displaceable members 3, 4 against relative movement in one direction whilst permitting relative movement in the other direction. As shown in Figure 2 the curvature and resilience of a leaf spring 10, forming the cam surface, are such that the weight of the window is not sufficient to cause the slidable locking member 7 to displace and pass the leaf spring 10. When an additional manual force is applied to close the window, the slidable locking member 7 will pass the leaf spring 10 and assume the position shown in Fig. 3. The manual effort required to overcome the support provided by the stay may be varied by adjustment of a grub screw 13 to alter the shape of the cam surface presented by the leaf spring 10. In an alternative embodiment, shown in Figure 8, the slidable locking member is formed by a resilient slide member 7 slidable on the inner surface of the tubular member 4 of the stay. Movement of a cam surface 10 attached to the telescopic member 3 of the stay causes the slide member to be expanded and frictionally grip the tube 4 to support the relevant load. Additional manual effort causes the cam surface 10 to pass completely through the slide member 7 to bring an abutment disc 18 against the slide member. A spring catch 21 is provided for locking the stay in its extreme open position.
