Abstract: 1346843 Coated screw-threaded members INTECO ESTABLISHMENT 28 April 1971 [6 May 1970] 11910/71 Heading B2E [Also in Division F2] In a method of protecting co-operating male and female threaded members, e.g. a bolt and a nut made of steel, against corrosion, the clearance between the threads is increased by etching away material from the male and/or the female thread, and then coating both threads electrostatically with a synthetic resin, e.g. an epoxy resin. The coating is applied as an electrically charged powder sprayed on to the members, which are earthed, the coating being cured by heating. The coating is applied in two stages, with the members held or supported by different surfaces in the two stages, so that their whole surface may be coated. Bolts may be suspended from a magnetic plate in one stage, and in holes in a perforated plate in the other stage (Figs. 2, 3, not shown).

Title: Improvements in devices for controlling the brakes of railway vehicles
IPC: B60T15/04
Filed: 1929-04-19
Abstract: 331,303. McDermid, W. F. April 19, 1929. Addition to 314,179. Fluid-pressure.-In valve mechanism of the kind described in the parent Specification whereby an application of steam or compressed air brakes in a locomotive is obtained proportional to that of the automatic vacuum brakes on the train, the valve piston is subject to the normal train-pipe vacuum on one side and to the variable vacuum on the other side. In making an independent application of the locomotive brakes however the pressures above and below the piston are equalized and the piston is actuated by a hand-controlled spring device which limits the brake cylinder pressure to a predetermined maximum. The device comprises a piston 3 the lower chamber 2 of which is directly connected to the vacuum train-pipe by the passage 4 and the upper chamber 2<1> by the passage 58 and a non-return valve 59. The capacity of the upper chamber 2 is increased by a reservoir connected by passage 55 and a chamber 56. Normally the chamber 17 connected to the brake cylinder is connected to exhaust bv the chamber 23. When air is admitted to the train-pipe to apply the brakes, the piston 3 rises and its stem 51 lifts the slidable sleeve 22 to close the exhaust and engages the stem 19 of the pilot valve 20 whereby the main air or steam supply valve 16 is opened, the operation being similar to that described in the prior Specification. When it is desired to obtain a higher maximum pressure in the brake cylinder, a sleeve 22<c>, Fig. 5, of smaller diameter than the sleeve 22 is substituted, this sleeve 22<c> fitting in a sleeve 22d and exposing a smaller area of the stem 51 to the brake cylinder pressure. Independent control of the locomotive brake separately from the train brakes is obtained bv the lever 32 provided with a cam 65 which permits a spring 10 engaging the sliding head 66 of a rod 61 to lift the piston 3 through a lever 62 connected to the rod. The spring 10 determines the maximum brake cylinder pressure in independent applications. When the spring 10 is operative the cam 65 also depresses a spring plunger 69 and stem 70 to unseat a valve 67 whereby the upper and lower piston chambers 2, 2' are connected through passages 55, 74 to equalize the fluid pressures on the piston.

Abstract: 970,078. Change speed control. NEW YORK AIR BRAKE CO. March 30, 1962, No. 12383/62. Heading F2D. [Also in Division F1] To compensate for change in density due to change in pressure in a gaseous fluid flow meter, a friction wheel 19, connected to a totalizer 24 through gearing 23, is positioned radially of a friction disc 17, connected to a vaned rotor 11 in a fluid flow line 10 through a magnetic coupling 13, 14, by pressure in the line 10 acting through a valve 59, a line 58, a spring-loaded bellows 53, a rod 54 and a lever 30 supporting a cam 26 by which totalizer rotation is increased as an appropriate power of the pressure. To adjust correction rate and for zero setting, springs 44 force-adjustable at 45, 46 act on the lever 30 through a bracket 38 which is adjustable in relation to the lever 30 by a screw 28 supporting the cam on the lever. The cam acts on an axially spring-loaded shaft 21 carrying the wheel 19 which has rollers 20 on its periphery engaging a friction coating 18 of the disc 17. The rotor 11 may be damped and may include reduction gearing.

Patent GB-1345296-A (GB)
Title: Storage configuration comprising a data circulation store
IPC: G06F17/30
Filed: 1972-03-17
Abstract: 1345296 Data storage systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 March 1972 [20 March 1971] 12584/72 Heading G4C A storage system includes a main cyclic store, for storing n words each of k bits, and an auxiliary cyclic store, for storing m k-bit words, m < n. The stores are so connected and controlled that words most likely to be addressed lie in the small store, so reducing the mean access time. In one embodiment, Fig. 1, the main store 1 comprises k shift registers and the auxiliary store 2 m shift registers. Each stored word comprises an address or search argument b. The address of a required word is passed via register AR to comparators AV1, AV2 where it is compared with the addresses circulating in the two stores. The shift rate of store 2 may be, for example, m times faster than that of store 1. If the requested word is in store 2 AV2 enables gate 12 so that the word passes to output register OTR. Alternatively if it is in store 1 AV1 enables gate 11, and the word passes to OTR. In the latter case the word may be passed via gate 13 to a location in store 2, the word being read out destructively or non-destructively as required from store 1 and if necessary displacing a word in store 2 which may be written back into store 1. Each word may include priority data d and transfer of an addressed word to store 2 may take place only if the priority of the word exceeds that of a word in store 2. In another embodiment, Fig. 2 (not shown), there is no address data in the words in store 1. Instead the address is determined by a cyclic counter (AC) cycling with the words in store 1. However, words in store 2 are accompanied by address data, the required address in the address register (AR) being compared (AV1, AV2) both with the successive addresses specified by the counter and with the address data l of the words circulating in store 2. Each word in store 2 also comprises priority data p, and when a word in store 2 is accessed the numerical value of the data p is incremented to record the number of times up to a preset maximum that the word has been accessed. If transfer from store 1 is required and there is no free word space in store 2 the word transferred overwrites any one word whose priority data does not show that preset maximum. Alternatively the priority data is incremented upon each cycle of store 2, the word to be transferred from store 1 replacing the word that has been longest in store 2. A third embodiment, Fig. 3 (not shown), employs only one comparator. A requested address is compared first with the addresses of the words in store 2. If the requested address is not found there, words are transferred from store 1 to replace a low priority words in store 2, and comparison of the addresses now in store 2 with the requested address takes place. This process repeats until the required word is found.
