Patent GB-785200-A (GB)
Title: Improved magnetic tape apparatus
IPC: F16D49/08
Filed: 1956-05-01
Abstract: 785,200. Band brakes. AMPEX CORPORATION. May 1, 1956 [May 26, 1955], No. 13429/56. Class 103 (1). A braking arrangement for the turntables of magnetic tape apparatus comprises bands 26 on the peripheral surfaces of drums 23 on the shafts 21 and 22 thereof which are so controlled that the brake torque on the table from which the tape is being removed is always greater than that on to which it is being wound but such that the difference is not sufficiently great to break the tape. One end of each band 26 is attached by a tension spring 29 to a fixed support, the coupling between spring 29 and band 26 including a slotted member 34 through which projects a fixed pin 32. The other ends of the bands are connected by operating rods 27 for operation by the arms of a rotary solenoid. Further springs 36 connected to arms 37 on the rods 27 act to tighten the bands 26. When the motors are de-energized after a fast forward or rewind operation, the formation of tape loops is prevented by the above braking arrangement in that assuming that the rotation of drums 23 and 24 is clockwise, the band 26 on the drum will tend to be rotated by the drum 23 until stopped by engagement with pin 32. Thereafter the braking torque is determined by the friction between the brake drum and the band, and the tension maintained by the weaker spring 36, and the brake is self de-energizing or self-relieving. The brake band 26 is similarly rotated clockwise until arrested by the stop nut 43 on the rod 27, the band tending to rotate against the tension of spring 29 being thus also self-relieving.

Title: Compositions for inhibiting corrosion of both cuprous and ferrous metals by aqueous solutions
IPC: C23F11/08
Filed: 1955-05-12
Abstract: 771,943. Preventing corrosion. ALBRIGHT & WILSON, Ltd. May 12, 1955 [May 12, 1954], No. 13807/55. Class 123 (1). In a system containing both cuprous and ferrous metals in contact with water having a zero or negative Langelier coefficient, corrosion of the ferrous metal caused by traces of copper dissolved in the water plating out on the ferrous metal with consequent local galvanic cell formation is prevented by adding to the water a thiol capable of retarding the solution of the copper and a phosphate which causes a protective film to form on the iron, zinc being present in the thiol or phosphate or as a separate soluble compound in sufficient quantity to prevent the thiol from interfering with the deposition of said film. The ingredients may be added continuously to the water or the phosphate and zinc added continuously whilst the thiol is added intermittently. The preferred thiols are those in which the thiol group is linked to a carbon atom in a heterocyclic ring, said carbon atom being linked to a cyclic amino group, for example 2-mercaptobenzothiazole. The thiol together with a small amount of a wetting agent is added to the water as a slurry in a quantity sufficient to form a protective film on the copper. The preferred phosphates are those of the alkali metals, especially sodium hexa metaphosphate, the amount of the phosphate ingredient being determined by the calcium content of the water to be treated. The zinc may be combined with the thiol or the phosphate but is preferably added in the form of a solution of a soluble zinc compound, for example, zinc chloride, sulphate, nitrate or acetate, the amount of zinc added preferably being such that the zinc : thiol ratio is from 1:4 4 to 1:1. In an example, the treated water contained 25 parts per million of phosphate, 2 parts of thiol and 2 parts of zinc.

Patent GB-184289-A (GB)
Title: Improvements in apparatus for measuring speeds
IPC: G01P3/06
Filed: 1921-05-18
Abstract: 184,289. Seguin, A. May 18, 1921. Differential and momentum speed indicators; transmission mechanism.- In apparatus of the type described in Specification 155,791, the gear-wheel 4 driven according to the speed to be measured carries a spring-controlled lever 11 pivoted at 12 and adapted to pick up and, at a fixed point, to release a striker 5 loosely mounted coaxially with the balance-wheel 6 and arranged to operate it by abutment against a pin 19. The balance wheel, controlled by a spring 7, is frictionally mounted upon a sleeve g<1> which is attached to the shaft g and carries a disc La provided with the pin 19. The lever 11 has a stud 13 to engage the striker head 2' and also a pin z to bear on a fixed cam formed with a nose 20. In operation, the lever engages the striker and drags it around together with the balance-wheel until the nose 20 is encountered by the pin z. This deflects the lever 11 outwards so that it releases the striker, which thereupon swings back with the balance wheel until again picked up by the lever 11. The friction-held pointer 9 has an arm 10 provided with a pin 8 which is positioned bv the striker or by the hooked end v of the lever, depending upon the sign of the speed variation until the striker and lever meet, whereupon the pin 13 rides up the inclined edge 1 of the striker, and engages with the radial edge 2 and thus releases the pointer pin 8. The spring r normally bears with its extremity upon the lever 11, but when the latter is moved outwardly by the cam nose 20 the point of bearing shifts to the pin z, thus temporarily increasing the effect of the spring. To prevent damage to the apparatus by reversal of the drive to the wheel 4, the driving-pinion e is loose on its shaft and is driven in one direction only through a pair of pawls 25 constituted by spring tongues of a cut-away plate 23 secured to the shaft. In a modification, shown in Fig. 9, the lever 11 is controlled as before by a cam, which then has the form of a groove A<1>, but the pointer extension 8 is engaged by the lever through the medium of a pin V mounted on a spring t. The return of the balance-wheel effects by means of a pin 19 the radial displacement of this spring and consequent release of the pointer. The pointer may be dispensed with and the striker coloured or rendered luminous so that it becomes visible at the moment of its collision with the pin 13. The striker may be driven at a reduced speed from the balance-wheel instead of rotating with it.

Title: Improved process of and apparatus for producing foam
IPC: A62C5/00
Filed: 1927-05-24
Abstract: 297,782. Schnabel, R., Jacobsen, J., and Excelsior Feuerloschgerate Akt.- Ges. May 24, 1927. Freely-flowing matter mixed in conduits.-In the method of generating foam by forcing a finelydivided gaseous 'pressure medium into a foam generating solution, both the gas and solution are subdivided and intermingled by passage under pressure, preferably together, through a mixing body or bodies such as a body or plate of ceramic material, stacked sieves or plates of asbestos, fibrous materials or textiles, sponge, or gravel or like filters. An alternative mixing body comprises a chamber into which the constituents are separately forced in whirling motion with their paths intersecting. The gaseous medium may be enriched by passage through a halogen or halogen compound before application to the foam generator, and may be put under pressure by means of a hand pump, air compressor &c. Anti-freezing or extinguishing compounds may be added to the foam generator. In the apparatus shown in Fig. 1, the porous septum is in the form of a hollow cylinder 32 within a casing 31 having a connection h for the foam pipe. Gas under pressure is supplied to the septum 32 by a pipe e from which a branch 30 leads to the container a to force the foam generator to the septum by way of a pipe 33. Dry foam generator might be housed in the cylinder 32, and the container a be charged with water. In a modification, Fig. 2, the mixing body 11 is arranged near the bottom of the container 6 for foam generator. Pressure gas is supplied to the body 11 by a pipe 16 controlled' by cock 18, and by a branch 17 to the space above the foam generator, so that the latter is forced through a sieve 9 and into the body 11 by way of an entrance 10 controllable in size by a screw plug 7. The foam formed passes by a tube 19 and a gravel filter 20 to the foam pipes 21. The mixing body 11, Fig. 4, comprises an annular chamber 23 which the solution enters by way of tangential nozzles 22, the stream of solution whirling round the chamber 23 and intersecing its path of entry before escaping through small outlets 24 to the pipe 19. The pressure gas pipe 16 also enters the chamber 23 tangentially in a direction to intersect the path of the solution. A test cock 14 is provided in the container 6. In a modification of this form of mixing body, the pressure gas enters the chamber 23 by way of a perforated annular pipe, and the whirling stream of solution is given a sudden change of direction in escaping from the chamber, the inner surface of which is of irregular outline.
