Title: Improvements in or relating to automobile brake arrangements
IPC: B60G11/12
Filed: 1931-11-09
Abstract: 390,240. Vehicle brakes. MOHL, S., 33, Amaliegade, Copenhagen. Nov. 9, 1931, No. 31062. [Class 103 (i).] To prevent interference with the operation of the brakes of a vehicle by the movements of the chassis on the bearing springs, the usual spring 4 is connected to a shackle 6 pivoted to the chassis at 8 and an additional spring 11 is connected to a point 10 on the shackle and the brake pull rod which is connected to the brake-operating lever on the wheel is arranged to coincide as nearly as possible with a line 13 passing through the pivot 8 of the shackle 6 parallel to a line passing through the point 10 and the middle point of the longest leaf of the spring 11. Since when the springs flex the points 7, 10 describe arcs of circles the centres of which are situated substantially at the middle points of the longest leaves of the two springs, the point 8 will describe an arc of a circle having its centre at a point on the line 13 adjacent the axle, this point being that at which the end of the brake lever should be situated. The distance between this point and the point 8 will therefore not vary. In order that the pull rod may pass substantially through the point 8 the forward end of the rod may be connected to a vertically swinging intermediate lever, the mean position of the end of which lies close to the point 8. The device may be applied to vehicles having a pair of rear axles in which the shackles 5 of the springs 4 of the two wheels, instead of being connected to the chassis as shown, are connected respectively to the ends of a balancer which is pivoted at its middle point on the chassis or in which one wheel is mounted directly on the end of the balancer as described in Specification 212,299, [Class 108 (ii), Road vehicles, Undercarriage details &c. for].

Abstract: 360,624. Brakes. LORMœLLER, B., 307, Seefeldstrasse, Zurich, Switzerland. Oct. 17, 1930, No. 31158. Convention date, Oct. 31, 1929. [Class 103 (i).] Actuated by motor-controlling appliances.-In a vehicle brake in which a power brake is controlled by the acceleration pedal, and two control members are arranged to be depressed by one foot of the driver, and so that by totally depressing one member the accelerator is moved through one portion of its path of travel, and by totally depressing the second member the gas pedal is moved through its full path, the points of contact for the foot are situated in an inclined plane below each other and the distance between them is arranged so that the upper member 37 is depressed by the sole and the lower member 39 by the heel of the foot. In Fig. 1 both members are shown fully depressed. The acceleration member 37 may be released whereby a stay 40 engages the member 39 and the member 37 is held in. the intermediate position. When both members are released the member 37 moves through its full path whereby the brakes are applied. In a modified form the accelerator member 5, Fig. 6, is guided in a hub 4 carried by a plate 3 supported by swinging links 2 on a bracket 1. The second control member 3a forms an extension of the plate 3. The plate 3 is adapted to engage a stay 1b

[Class 52 (ii).] The chair-bedstead claimed in Specification 287,989, [Class 52 (ii), Furniture for sitting &c. upon], is so modified that the intermediate frame or panel, instead of being pivoted directly to the main frame of the structure, is indirectly pivoted thereto in such a manner as to enable it to be extended forwardly of the main frame to constitute the intermediate section of a bed or to overlie said main frame to constitute the seat of the chair while the leg section is extended to constitute a leg-rest. Figs. 11 and 12 show such a device, the intermediate section I being pivoted to the main frame by links o. A modification is shown diagrammatically in Figs. 1, 2, and 3, the back section being omitted in these Figures, in which the intermediate section I is pivoted to blocks b slidable on the main frame c.

Title: Preparations of use for the determination of calcium
Inventor: BARON DENIS NEVILLE
IPC: G01N33/84
Filed: 1959-09-14
Abstract: A tablet for semi-quantitative estimation of calcium in body fluid comprises a reagent giving a colour change with calcium ions, an aminopolyacetic acid or water-soluble salt thereof, lithium hydroxide, a tableting lubricant and an inert diluent, the proportions being such that on addition to water to which the fluid is added a pH of 12-12,5 is obtained.  By providing a reagent which undergoes the same colour change in the presence of calcium and magnesium ions and on addition to water produces a pH of 9,8-10,2, a tablet suitable for estimating total hardness of water is obtained. Specified colour reagents are calcein (a fluoresceiniminodiacetic acid complex), preferably mixed with thymol phthalein, and Calcon (1-(2-hydroxy-1-naphthylazo)-2-naphthol-4-sulphonic acid), Cal-red (2-hydroxy-1-(2-hydroxy-4-sulpho-1-naphthylazo)) -3-naphthoic acid and alizarin black SN, and for magnesium also, Eriochrome black T. Specified aminopolyacetic acids are ethylene diamine tetraacetic acid, cyclohexane diamine tetraacetic acid and ethylene glycol bis-(b -amino ethyl ether) tetraacetic acid.  The lubricant may be boric acid, which also serves as a buffer component, and excipients mentioned are sodium chloride, sodium carbonate, dextrose and citric acid.  Two formulations are exemplified, in one of which the tablets are prepared by drying sodium chloride and lithium hydrooxide, mixing with disodium EDTA and boric acid by grinding in a ball mill, spraying the mixture with Eriochrome black T in methylated spirit, sieving, drying and compressing into tablets.

Abstract: 1,184,586. Testing filamentary material. C.A. LITZLER. July 10, 1967 [July 28, 1966], No.31643/67. Heading G1S. A continuously supplied length of filamentary material is tested by forming a loop of the material which is tensioned by providing a speed differential between input and output elements feeding the loop, and measuring the tension in the loop and the extension due to the tension, from the speed differential; in addition, the input and output means may be clamped and the loop then tensioned by other means such as a hydraulic piston, while the resulting tension and strain are measured and recorded. As shown in Fig. 3 the filamentary material or cord 13 is threaded through an accumulator C, around capstans 23, 24 and dancer pulley 30 to form a loop and through a further pulley system to a wind-up mechanism E Fig. 3 (not shown). A constant tension is applied by the speed differential of capstans 23, 24, a strain guage being associated with pulley 30 to indicate the tension. The elongation caused by the tension is measured by sensing the speed differential of the capstans 23, 24, the ratio between these two speeds being manually controlled by a trimming vernier potentiometer. In addition a static test is effected at spaced time intervals, the cord being clamped by toggle clamps 38, 39 and the pulley 30 moved downwardly by a hydraulic piston 35. The tension in the loop is measured by the strain gauge or load cell mounted on the pulley 30 and the tension on the cord is recorded on a recorder 40. The toggle clamps are then released and the capstans 23, 24 rotated at higher speeds to take up slack in the accumulator C.

Fig. 5 shows a coupling comprising condensers kl, k2 and inductances l1, l2 which may be interchanged, Fig. 1 (not shown). In a modification, Fig. 3, the two coupling circuits are arranged diagonally as shown so that the series mode of oscillation excludes the coupling circuit while the figure of eight oscillation is through K1, l<1>2, k<1>2, K2, l<1>1, k<1>1, instead of one mode of oscillation being through the coupling inductances and the other mode through the coupling condensers as in the previously described arrangements. In a further modification, Fig. 4, in which the coupling inductances l1, ¢ l1 and l2, ¢l2 are respectively tightly coupled so that the inductances ¢l1 and ¢l2 carry twice the current that the inductances l1 and l2 carry when oscillating in the figure of eight or bridge mode. The arrangement may be used to give band-pass coupling and the band width may be made adjustable by making the coupling circuit adjustable. The coupling unit,may be made as a separate unit and be separately screened. Fig. 5 shows the application to a supersonic heterodyne receiver in which local oscillator energy is supplied at LO, the received carrier at RC while the output energy of beat difference frequency is taken off at OT. The potentials of the couplings are arranged as shown so that re-radiation is avoided.
