Title: Improvements relating to servo brake mechanism
IPC: F16D51/66
Filed: 1927-05-09
Abstract: 294,720. Clark, D'A. M., (Bendix Brake Co.). May 9, 1927. Blocks and shoes acting on drums; actuated or applied by running axle or wheel.-A brake comprises a pair or more of articulated floating shoes having limited circumferential movement in either direction of rotation of the brake drum and a servo-shoe disposed between the free ends of the shoes and connected through powermultiplying means to apply the main shoes to the drum. The brake shown comprises a pair of floating shoes 24, 26 hinged together and provided with slots 28 through which pass anchoring pins 30, 32. The shoes are held in the disengaged position by springs 40, 36, an adjustable eccentric stop 38 being provided adjacent the pivot. The shoes are confined laterally by plates 42 secured to the fixed backing-plate. A floating servo-shoe 50 disposed between the ends of the shoes 24, 26 is adapted to be forced against the drum by a segmental roller 58 disposed between the shoe and an eccentric pin 56 on a rock shaft 18 operable by the main pedal or equivalent. The shoe 50 normally rests upon a roller 52 at one end under the influence of a spring 54 connected to an arm on shaft 18 and it engages at the other end a floating lever 62 carrying two rollers 64, 66 disposed in semi-cylindrical recesses in the ends of a pair of thrust members 68, 70 pivotally connected at 72, 74 to the ends of the shoes 24, 26. The idle position of the lever 62 and members 68, 70 is determined by a hook on the member 68 embracing a pin 76 on the backing-plate. Thus when the servo-shoe 50 is applied to the drum by rocking the shaft 18 its movement in one direction or the other according to the direction of rotation of the drum forces the thrust members 68, 70 apart so effecting the engagement of the shoes 24, 26 with the drum, these shoes then anchoring at one or other of the pins 30, 32 so that one shoe applies force to the other. The brake is shown applied to a vehicle steering wheel, the shaft 18 being provided with a crank arm engaged by a horizontal lever pivoted on the fixed axle.

Title: Improvements in apparatus for measuring fluid flow
IPC: G01F3/08
Filed: 1943-09-07
Abstract: 567,979. Filtering. KENT, Ltd., G., and COLEY, S. G. Sept. 7, 1943, No. 12737 /42. [Class 46] [Also in Group XIX] For use in apparatus for measuring fluid flow, a counter device comprises a doubleacting striker 19, an electrically-controlled mechanism to move the striker periodically to and fro and a rotatable cam having lobes 23 engageable by the striker, the striking components 22 of the striker and the lobes of the cam being so relatively arranged and formed that as one component 22 moves into engagement with a lobe to advance the cam in one direction, the other component 22 leaves the gap between adjacent lobes and finally takes up a position to engage and displace in the same direction a lobe (and hence the cam) when the striker 19 is reversed, the cam being held against displacement in the intervals between movement of the striker by the component 22 disposed between the lobes. The invention is applied to a meter for measuring the quantity of fuel fed from the tanks of an aircraft to the engines. The fuel enters the meter at 2, passes through a filter 8 and oscillates a member 4 in a measuring chamber 5 before passing to an outlet 3. The member 4 drives a switch mechanism through reducing gear 6. The filter and the metering apparatus can be byepassed by operation of a lever 11 which opens a valve 10. The switching mechanism sends impulses to an electromagnet 13, Fig. 3, which operates the striker 19 through a parallelogram linkage. Counters for multiengined aircraft can be arranged side-by-side. At the end of its stroke, the electromagnet 13 opens a switch 24 to put an extra resistance 25 into circuit.

Title: Improvements in or relating to the degradation of dextrane
IPC: C08B37/02
Filed: 1944-07-10
Abstract: Partially depolymerised dextrane is prepared by subjecting at least partially water soluble microbiologically produced dextranes to an acid hydrolytic treatment under controlled conditions of time temperature and acidity so that only partial breaking down of the starting material takes place.  The product is isolated by any method known to be capable of separating as hydrolysis or degradation product from the hydrolysis or degradation reaction medium.  The conditions of reaction are adjusted so that products are obtained which are completely water soluble and which at a concentration of 0.7 per cent in aqueous solution have a sedimentation constant of from 1.5 X 10-13 to 20 X 10-13 and a diffusion constant of from 0.2 X 107 to 8 X 107, and the relative viscosity of which at a concentration of 4 per cent in aqueous solution shows a value of from 1.5 to 15.  The preferred reaction conditions comprise a treatment with dilute hydrochloric acid at temperatures of 30 DEG  C.-150 DEG C. for less than 24 hours followed by dialysis of the solution.  In examples a microbiologically produced dextrane is hydrolysed with dilute hydrochloric acid for varying periods, the product neutralised and precipitated with alcohol.  It is then re-dissolved in water and dialysed in a cellophane bag against distilled water.  The products are used as injection or infusion fluids either alone or in combination with other physiologically active salts.
