Title: Improvements in or relating to the generation of impulses
IPC: F16F15/14
Filed: 1938-11-16
Abstract: 521,503. Oscillation dampers. SARAZIN, R. R. R. Nov. 16, 1938, No. 33346. Convention date, Aug. 2. [Class 108 (iii)] [Also in Group XXVI] In order to damp rotary or unidirectional impulses of, say, velocity N in an aircraft wing, propeller engine &c. a rotary member or disc 5 driven by a motor at, say, n revolutions is arranged on or parallel to the axis of the propeller &c. and carries groups of pendular systems having the same natural frequency nf but of different phase arranged around the disc so that when they oscillate either due to the disturbing force to be balanced or mechanically by push rods &c. the resultant force due to the pendular systems acting on the disc rotates at a speed relative to the disc which is different from the velocity n, such that N= (n-nf) and is equal and opposite to the force to be balanced. In Fig. 1 the direction of the force to be balanced is along an axis XOX<SP>1</SP> rotating at N revs. and the disc 5 rotating about an axis O at n revs. carries two groups of pendulums p<SP>10</SP>, p" and p<SP>20</SP>, p<SP>21</SP> of the same natural frequency but of different phase and pivoted at 90 degrees to one another. The force to be balanced may be resolved into two components f<SP>10</SP>, f having the same natural frequency as the pendulums and which generate in the pendulums p<SP>10</SP>, p<SP>11</SP> and p<SP>20</SP>, p<SP>21</SP>, at any instant a force equal and opposite in value to the forces f'‹, f<SP>20</SP> respectively. In Fig. 5 an air-screw 6 is driven by an engine 7 through step-down gearing at a speed N and the engine shaft rotates at a speed n. In order to balance a disturbing force set up by the propeller 6 a pendulum system 5 having a natural frequency nf=(n-N) is attached to the crank-shaft Similarly, a device with pendulums 8 mounted on the propeller shaft would permit of compensation of a rotating force originating in the running of the engine, e.g., a force of order 1 relative to the engine shaft such as that created in radial engines, by the connecting rod systems having a master rod and articulated rods. The pendulum systems may be formed by masses of mercury displaceable in cavities in pinions of the step-down gearing. By combining two pendular systems a pulsatory force whether rotating or not may be balanced each system balancing half the force and rotating at different speeds and frequencies.

Abstract: 623,581. Adjusting radio receiving apparatus. WEYMOUTH RADIO MANUFACTURING CO., Ltd., and JORDAN, B. I. Nov. 12, 1946, No. 33549. [Class 40 (v)] In a permeability tuning system for a radio receiver having a number of variable frequency tuned circuits, the position of cores in relation to associated coils is controlled by a shaft which acts on a member carrying the cores through a cam mechanism. The shaft may also control a wavechanger switch, so that multi-band tuning can be effected by means of a single control. Fig. 10 and Figs. 4, 6 and 8 show a sectional plan, and various sectional end views of an embodiment in which a shaft 4 carries an eccentric circular cam 6, embraced by a follower 19 (Fig. 4). The follower 19 is attached to a plate 7 (Figs. 4, 6, 8) which carries iron dust cores 8-11 (Figs. 6, 10) and is constrained to move vertically by a telescopic guiding system 16-18 (Figs. 4, 6, 10). The cores vary the inductance of two sets of coils 12, 13 (Figs. 6, 10) and 14, 11 (Figs. 6, 10), respectively tuning the oscillator and signal frequency tuned circuits over long and medium wavelength bands. Cam - operated switches 33-25 (Figs. 10, 8) and 33-43 (Fig. 10) are provided to switch in the isolated set of coils when the cores pass through one extreme position and out again when the cores reach their other extreme position. Coupling windings are provided on the signal frequency coils. The Provisional Specification describes commutator type wave-change switches.

In operation, as the two conical surfaces approach one another, a switch 70, 73 releases a fluid pressure from behind a piston 54 via a passage 59 to allow the device 56 to permit movement between the surfaces 60, and the conical surfaces to align without damage, and then after further approach a switch 71, 73 allows pressure fluid to flow to the cylinder behind the piston 54 to lock the aligned surfaces 60. Initially there is a clearance (Y), Fig. 4, not shown, between a cone member 50 and an abutment ring 45, but this is closed by radial expansion of the member 50 to provide an effective seal to the preform cavity 41. In Fig. 1, not shown, the mandrels are supported radially on a turret.

Title: Improvements in or relating to derivatives of sexual hormones and of compounds containing a cyclopentano-polyhydrophenanthrene ring system, having like biological action
IPC: C07J75/00
Filed: 1936-12-12
Abstract: Medicinal compounds suitable for peroral administration are prepared by condensing a compound of the cyclopentanopolyhydrophenanthrene series which is either a sexual hormone or which has the biological action of a sexual hormone, with a polyhydroxy ketone or a polyhydroxyaldehyde or a derivative thereof containing one or more halogen or acyl substituents or both.  Starting materials mentioned include oestrone, dihydro-oestrone, monoacyldihydro-oestrone, androsterone and dehydroandrosterone.  It is stated the products of the invention are glucosides or glucoside-like condensation products. Instead of the carbohydrates themselves, partly acylated carbohydrates such as penta-acetyl glucose, or halogen derivatives thereof such as aceto-bromglucose may be used.  The condensation may be assisted by catalysts such as toluene sulphonic acid, and in the case where halogen derivatives are used, a base which binds the hydrogen halide such as silver oxide or carbonate or mercury acetate may be present.  When an acylated carbohydrate is used in the condensation, the final product may be saponified to remove some or all of the acyl groups.  In examples: (1) a quinoline solution or suspension of oestrone and aceto-brom-glucose is allowed to stand at room temperature in the presence of freshly precipitated, dried silver oxide.  The reaction product is extracted with chloroform, to give the tetra-acetyl glucoside of oestrone.  Saponification by means of sodium ethylate gives oestrone glucoside which is soluble in water; (2) a benzene solution of oestrone and aceto-brom-glucose are heated in the presence of mercuric acetate.  The benzene solution is washed with alkali and the resulting glucoside crystallized from ethyl alcohol; (3) a mixture of oestrone, penta-acetyl glucose and toluene sulphonic acid is kept for one hour at 125 DEG  C. and then extracted with benzene to give the corresponding glucoside; (4) dihydro-oestrone and aceto-brom-glucose are heated in quinoline solution in the presence of freshly precipitated dry silver oxide and the product worked up as in example 1.
