Filed: 1934-01-17
Abstract: 428,485. Combination locks. ADAMS, J. S.,3, Emerald Street, Bloomsbury, London. Jan. 17, 1934, No. 1698. [Class 44] A combination lock for tills and like drawers comprises finger-actuated pieces 1 at the front of the drawer which operate levers 4 having links 6 selectively connectible to one or other of two points 7, 7a on members 8 which are thus lowered or raised, according to the point of connection, on operation of the finger pieces and so permit or, with an incorrect combination, prevent an abutment plate 10 being lowered out of the way of a stop provided on the drawer housing. On an attempt to open the till with a wrong combination the abutment 10 is pushed back by the fixed stop on the housing and so rocks the plate 12 which carries an arm 17 operating an alarm bell.

Title: Improvements in or relating to the manufacture of glutamic acid
Filed: 1948-01-21
Abstract: Steffen's filtrate from the de-sugarizing of sugar beet solutions is hydrolysed, the pH adjusted to 1.6, salts crystallized, the pH of the resultant solution brought to 3.2, and glutamic acid recovered therefrom.  Hydrolysis may be effected with acid or alkali.  Thus, 100 parts of filtrate is treated with 50-150 parts of 35-37 per cent HCl at 100-125 DEG  C., for 0.25-8 hours, soduim hydroxide or ammonia added to a pH of 1.6, insolubles including humin and salts filtered, the hydrolysate concentrated at not more than 100 DEG  C. to about 75-90 per cent by weight of the initial filtrate, and salts crystallized at about 30-60 DEG  C.  A filtering step may be employed prior to adjustment of the pH.  The alkaline hydrolysis may be effected, preferably with about 8 per cent by weight of sodium or calcium hydroxide, and not above 85 DEG  C. for about 2 hours. Mineral acid such as hydrochloric or sulphuric is added to give a pH of 1.6.  Glutamic acid is crystallized from the salt-free solution after adjusting the pH to 3.2.

Filed: 1945-01-23
Abstract: 576,241. Pumps. BRITISH THOMSONHOUSTON CO., Ltd. (General Electric Co.). Jan. 23, 1945, No. 1859. [Class 7 (ii)] [Also in Group XXVI] In a super-charging system in which several exhaust - driven turbo - blowers receive their supply of exhaust gas and deliver their compressed charges in parallel, means is provided for automatically idling one of the blowers when the load is reduced to a predetermined low value ; operation of the blower at or near pulsasation point is thus avoided. As shown two blowers 6, 7 are fed by an exhaust conduit 5, having a waste gate valve 22, and deliver air to a carburetter 3, and a valve 25 in the delivery passage 12 of the blower having the higher pulsation point, is arranged to close before this point is reached. Connected with this valve is a valve 26 in the appropriate exhaust branch, the valve remaining open a sufficient amount to allow an idling supply of gas. A port 32 which is simultaneously opened by a valve 33 prevents pressure building up on the delivery side of the compressor.

Title: Improvements in hobs for cutting gear teeth
IPC: B23F21/16
Filed: 1921-01-14
Abstract: 160,447. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Labberton, J. M.). March 13, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Milling-cutters.-The invention relates to hobs such as is shown in Fig. 3, with the angles a of inclination of its side faces equal to the pressure angle and its depth d equal to the height of the teeth cut, each hob being designed for cutting the spur. bevel, or helical involute teeth referred to in Specification 153,581, [Class 80 (i), Gearing, Belt &c.]. In determining the dimensions of the said involute teeth having given the usual particulars-the distance between gear centres, the gear ratio, and the diametral pitch-an assump-- tion of the desired amount of rolling-action be-- tween the gear teeth is made and is used as a basis in solving a series of equations based on a mathematical consideration of the action and construction of the gearing. A diagram, Fig. 1, is drawn embodying the pitch circles contacting at the point o, the base circles x<1> y<1>, the line of of pressure x, y and tooth curves S, T contacting at the point o. Points s', t' on the curves S, T, respectively, are chosen to represent the points at which the first and last contacts with the tooth points t<2>, s<2> are made. Tangents to the base circles are drawn from the points s<1>, t<2>, t', angles subtended at the gear centres y', y<2> being designated as shown. Calculations are then made equating the angle c' with quantities involving the ratio of the curve s' o to the curve t<2> o, the gear ratio, and the angle b. The angle C<SP>2> is similarly equated. An assumption of the required value of the ratio s<1> o : t<2> o, which represents the proportion of rolling taking placebetween the teeth and which should be rather less than unity, is then made, so that the angles c', c<2> in terms of b, or in terms of a, the pressure angle, as b=tan a, can be calculated. Further assumptions are then made that the length of contact surface t<1>t<2> and the total length of each tooth are each equal to half the circumferential pitch. Based upon the first of these assumptions, such calculations are then made as to produce an equation in which by substituting the values of c', c<2> previously obtained, the value of a, the pressure angle of the gears, is determined. The addendum of each wheel is then determined by subtracting the pitch radii' r<2>, r<1> from the lengths of the lines t<2>z<2> and s<2>z<11> (not shown), which lengths are obtained in terms of the angles shown and of the radii r<2>, r<1> from the lengths of the lines t<2>z<2> and s<2>z<1> (not shown), which lengths are obtained in terms of the angles shown and of the radii of the base circles. Fig. 2 shows a curve stated to be obtained by calculation and designed to give equal strengths of teeth in the two wheels, the abscissµ denoting the gear ratio R and the ordinates the relative thicknesses of the teeth on the pitch line.

Jan. 23, 1933, No. 2187. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 24, 1933]. [Class 38 (v).] In pressureoperated control switch such as may be used in connection with refrigerating apparatus which is arranged to be opened additionally by electrical overload, the over-load-responsive-member being arranged to be returned manually to its working position after cessation of the overload, the movable switch member is provided with an operating projection arranged to be engaged by the resetting- device for maintaining the switch open as long as this device is in the resetting position. As shown the control switch is adapted to be operated by an expansion bellows 16 and rod 15, the upper end of the rod being connected by a dead-centre snap-action spring 17 and link 18 to a contact lever 12 pivoted at 13. In addition the contact lever is adapted to be opened by an electrical overload device consisting of a bimetallic strip 24 provided with a heating coil 25 the lower end of the bimetallic strip normally engaging and holding down a spring-pressed pivoted lever 22. If, however, the strip is unduly heated its lower end flexes and releases the lever 22 which is moved by its spring 23 to engage the contact levers 12 and move it to its " off " position. To reset the lever 22 a projection 28 is rotated by a knob 27 to engage an inclined portion 29 of the lever 22 and, according to the invention, the knob 29 during this resetting movement engages also a spring 30 carried by the lever 12. Thus the switch member 12 is held in its open position independently of the bellows 16 until the lever 22 is reset in the position in which it is re-engaged by the bimetallic strip after the latter has cooled down. Adjustment of the spring 19 bearing on the bellows-operated rod 15 is effected by means of a knob 21. Specification 367,189 is referred to.

The bands or rollers may be adjustable to vary the width of the channel, and the rollers may be curved, e.g., as on the right of Fig. 4. The pressure board 7 is adjusted by screws 9. The top of the channel may be formed by another endless band running over the board 7, in which case the screws 9 are arranged on one side.
