Abstract: 536,181. Cams. SULZER FRERES SOC. ANON. Nov. 3, 1939, No. 29340. Convention date, Feb, 8, [Class 80 (iii)] In cam mechanism, particularly adapted for operating fuel pumps, the width of the track or roller engaging surface 5 of the base circle of the cam is less than that of the nose or projection 6. The change-over from the narrow track to the full width is designed in accordance with the load curve of the cam. The inoperative surfaces 7 8 on both sides of the narrow portion may be surfaces of a cone or a cylinder. The cam roller is preferably of light construction as regards its moment of inertia. The object of the invention is to prevent slip between roller and cam without the use of heavy loading springs.

Patent GB-366556-A (GB)
Title: Method of producing potassium formate
IPC: C07C51/41
Filed: 1930-10-08
Abstract: Potassium formate is obtained by treating an aqueous solution containing 40 to 70 per cent of potassium formate and respectively 60 to 30 per cent of calcium formate with potassium sulphate until practically all the calcium contained therein is precipitated and an aqueous solution of potassium formate is left, separating the precipitate, which consists of the double sulphate of potassium and calcium, and treating it with calcium formate or a mixture of constituents adapted to produce the latter in situ, so as to recover a solution of potassium and calcium formates similar to the initial solution, the residual precipitated by this treatment consisting substantially of gypsum.  According to one example an aqueous solution of calcium formate is stirred with potassium sulphate.  The solution of potassium formate and calcium formate thus formed is filtered off from the precipitate and treated with a further quantity of potassium sulphate at 30-40 DEG  C.  The potassium formate solution produced is filtered off.  The precipitate consisting of potassium-calcium sulphate is washed and stirred with a fresh solution of calcium formate, yielding a solution of potassium and calcium formate similar to the initial solution, and a precipitate of pure gypsum.  According to another example, milk of lime is mixed with quicklime and potassium sulphate, and treated at 180 DEG  C. and 12 atmospheres pressure with carbon monoxide.  The resulting solution of potassium and calcium formates is stirred with potassium sulphate, the resulting solution of potassium formate separated, and the precipitate of potassium-calcium sulphate treated in an autoclave with milk of lime and carbon monoxide to recover a solution of potassium and calcium formates, gypsum being precipitated.

Abstract: 1432420 Multi-gap cold-cathode tubes NIPPON ELECTRIC CO Ltd 27 June 1973 30454/73 Heading H1D [Also in Division H4] An electrostatic recording device for use in a facsimile receiver comprises a hermetically sealed gas filled envelope 150 containing a linear array of scanning electrodes 111-117 with a common (anode) electrode 140. By applying a negative start pulse 181 and threephase negative pulses 182-184 as shown, a gas discharge is shifted sequentially along the array. In addition the envelope contains voltage pickup electrodes 121-127 disposed in one-to-one correspondence with the scanning electrodes which pickup the potential developed in the discharge space by the ionic conduction one after another to provide voltages sequentially to recording stylus electrodes 131-137 past which electrostatic recording paper 191 is moved over a grounded electrode 192. The facsimile video signal to be recorded is applied to terminal 175. According to the invention the ionization coupling between the scanning and pickup electrodes is improved by locating the tips of the pickup electrodes 331-333, Fig. 3, within recesses in the scanning electrodes 311- 313, the common electrode 341 being located above the co-planar scanning and pick-up electrodes. Two recesses may be provided in each scanning electrode, the tip of each pickup electrode being similarly divided.

[Class 37] A liquid volume indicator of the variable capacitance type comprises one or more parts of condenser plates 13, 14, which may be spaced edge-to-edge lengthwise of the liquid container, the arrangement minimising errors in reading when the container is tilted. In order to maintain a-linear relationship between volume of liquid and condenser plate area immersed, the plates are non-uniformly perforated and/or non-uniformly spaced apart. Fig. 3 shows an indicator circuit comprising an oscillator connected to an amplifier-detector through a filter circuit 38...40. The liquid container is shown at 10, and variations of the capacitance with liquid volume allow the oscillator current to pass the filter circuit and energize the indicator coil 48. This coil is mechanically coupled with a core 52, movement of which restores the normal cut-off frequency relationship between the filter and oscillator. Reference is made to the use of this invention on aircraft.
