Patent GB-172489-A (GB)
Title: Apparatus for playing a race game
IPC: A63F9/14
Filed: 1920-10-28
Abstract: 172,489. Grossi, S. Oct. 28, 1920. Race games, mechanical.-Relates to race game apparatus of the kind wherein competing players rotate handles attached to operating spindles to move model figures along tracks or up poles under the control of centrifugal devices which disconnect the driving mechanism at a critical speed. According to the invention each centrifugal device comprises a single arm pivoted to the operating spindle and having its lower end normally in driving engagement with the usual winding bobbin whereby, if the critical speed is exceeded, the pivoted arm disengages itself by centrifugal action from the bobbin. The winning figure deflects a catch, thus allowing an electric switch to close and illuminate the corresponding lamp. The attendant, by operating a hand-lever attached to an horizontal bar carried after the manner of a parallel ruler, may raise or lower the winding bobbing into or out of driving engagement with the pivoted arms. In the form known in Figs. 1 and 2, monkey figures are drawn up poles 2 by means of cords passing from winding drums 4 over the tops of the poles. The winding drums are loose on the operating spindles 5 but are caused to rotate, when the handles 6 are turned, by means of pivoted arms 11 which engage projections 12 on the drums. If a handle is turned too quickly, the corresponding arm 11 moves out of engagement with the winding drum and the monkey descends until the speed is reduced. On reaching the top of the pole the monkey displaces a catch 32 and allows electric contacts 26, 27 to close and illuminate a lamp. The winding bobbins 4 may be raised or lowered to place them simultaneously in or out of driving reach of the arms 11 by means of a bar 15 supported on links 16 and operated by a hand-lever 21. In a modification, the bar 15 may be operated by a solenoid when the winning monkey closes the electric contacts 26, 27, thus causing the descent of all the monkeys and the illumination of the winner's lamp.

Title: Extraction of alkaloids
Inventor: LEWKOWITSCK PHYLLIS REGINA ELS
IPC: C07D455/08
Filed: 1957-10-02
Abstract: Ipecacuanha is extracted with an aqueous mineral acid, the aqueous extract is treated with one or more protein digesting enzymes at an appropriate pH, the treated extract is rendered alkaline and the liberated alkaloids are recovered from the alkaline solution.  The preferred enzyme is papain, the activity of which is suitably promoted by the addition of a small quantity of a compound containing sulphur, such as cysteine or sodium dithionite, and the pH when this enzyme is used is advantageously in the range of 4 to 8.  The temperature at which the enzyme treatment is effected is suitably in the range 10 DEG  to 70 DEG  C., and the treated extract is preferably rendered alkaline by the addition of magnesium oxide or sodium hydroxide and the alkaloids recovered, for example, by extraction with a water-immiscible solvent.  The ipecacuanha used in the process is preferably in a whole condition, but it may be ground before treatment with acid. Examples are given.  Reference has been directed by the Comptroller to Specification 767,224.

Abstract: 915,910. Gas-producing compositions. AVIATION, MINISTER OF. Oct. 8, 1957 [Oct. 10, 1956], No. 30927/56. Class 9 (2). A plastic gas-producing composition consists of an intimate mixture of constituents including a solid oxidizing agent and a visco-elastic liquid binder which is a polymeric aliphatic hydrocarbon with side groups having a viscosity in the range 250,000 to 7,000,000 poises at 25‹ C. Oxidizing agents specified are ammonium nitrate and ammonium perchlorate. Suitable binders are polyisobutylene and polypropylene; an alkyl ester, e.g. ethyl oleate may be added as a plasticizer. A surface active agent containing an alkali metal alkyl sulphate, ethyl oleate, tetrahydrofurfuryl oleate, pentaerythritol dioleate, or sodium dioctyl sulphosuccinate is preferably also present. Other ingredients are coolants to modify the burning action, such as ammonium picrate, oxamide, and ammonium dichromate, and catalysts to increase the burning rate (copper oxide, copper chromate, or chromium sesquioxide), to. make the burning regular (titanium dioxide), and to suppress flash (copper compounds). In making the composition, finely powdered ammonium perchlorate is mixed with the other ingredients at 140‹ F. and then passed between knurled rolls rotating at different speeds; the mixture is then treated in a deaerating pug mill, passed into a vacuum chamber at 160‹ F., and finally extruded. The composition is suitable for use in rocket motors, engine starter cartridges, and fluid ejection systems. According to the Provisional Specification, the binder may be a polyester or polyglycol which has been chain extended by a diisocyanate. Specification 874,564 is referred to.

Filed: 1928-10-26
Abstract: 300,199. Bragg, C. S., and Kliesrath, V. W. Nov. 8, 1927, Convention date]. Fluid-pressure. - Fluid brake mechanism for vehicles comprises a pressure regulating valve between the source of lower fluid pressure and the brake cylinder adapted automatically to maintain a predetermined degree of rarification available for operation of the brake cylinder. This valve is readily adjustable by hand while the vehicle is travelling and comprises a casing 30 connected to the induction pipe of the vehicle engine by means of a pipe 26 and to the control valve by means of a pipe 26<a>. A diaphragm 36, held between the casing 30 and a screwed cover 31 and having a central aperture 38 is adapted to seat on the end of a. pipe 34 leading from the pipe 26 and cut it off from the interior 35 of the casing 30. A second diaphragm 37 is also held between the casing 30 and the cover 31, the marginal portions of this diaphragm being in engagement with the diaphragm 36 and a hand lever 51 is connected by links 39, 50 to the diaphragm 37 in order that the diaphragms may be adjusted with respect to one another. When the vehicle engine is running air is exhausted from the space between the diaphragms, the chamber 35 and the brake control valve; when the latter is operated to apply the brake air is drawn from the brake cylinder into the chamber 35 raising the diaphragm 36 and passing into the pipe 34. To reduce the amount of vacuum available the lever 51 is moved to allow the diaphragm 37 to be pressed by the atmospheric pressure on its outer surface down upon the diaphragm 36, thus more pressure is required in the chamber 35 to lift the diaphragm 36. The pipe 34 is made of larger diameter than the pipe 26 and the pressure rises in the space between the diaphragms and the pipe 34 before that in the pipe 26 and causes the diaphragm 37 to rise this being allowed by a slotted link connection 39<a>. The pressure regulating valve acts also as a non-return valve and prevents fluctuations in the degree of rarification in the induction pipe being transmitted to the brake cylinder. The brake control valve comprises a casing connected to the foot-pedal and enclosing a pair of valves mounted on a rod connected to the brake rigging, the brake cylinder is connected through the hollow valve rod to the space between the valves and one side of the valves is connected to atmosphere and the other to the induction pipe of the vehicle engine. The Specification as open to inspection under Sect. 91 (3) (a) states also that the device may be applied to apparatus in which the brake piston is submerged in vacuum in the released position as described in U.S. Specifications 506 and 94412. This subject-matter does not appear in the Specification as accepted.
