Title: Garters and methods of making them
IPC: A41F11/16
Filed: 1920-07-16
Abstract: 165,344. Frost, G. A., and Frost Co., G. July 16, 1920. Garters.-Pad garters of the kind described in Specifications 136,802 and 136,803 are formed from blanks which are wider in their middle portions than at their ends, the wider portions being folded to form the pad A. Such blanks may be made in strip form and afterwards divided. Such a strip may be tubular, the ends of the leg band B being inserted in the open ends of the padforming portions. The widening may be effected on one or both edges of the strip, and a solid blank may be formed with tubular ends to receive the leg band. One garter may be made with two pads from a double blank, as shown in Fig. 19, and in this case the pad-forming portions need not be widened.

Abstract: 711,555. Reciprocating pumps. GREER HYDRAULICS, Inc. Aug. 28, 1952 [Sept. 10, 1951], No. 21639/52. Class 102 (1). In a revolving cylinder pump the cylinder block or rotor 14 has a plurality of axially aligned radial passages 17 therein and is surrounded where it passes through a supply chamber 51 formed in the pump casing 11 and containing the pump inlet port 12 therein, by a balancing ring 151 having the major portion of its outer surface spaced from the walls of the chamber 51 and having a discharge chamber 157 that receives liquid pumped through the radial passages 17 and is in communication with both the pump outlet port 13 and balancing chambers 154, 155 diametrically opposite the discharge chamber 157 and laterally adjacent the radial passages 17, both the balancing and discharge chambers being in communication with the outer surface of the rotor 14. The balancing ring 151 is formed along substantially one half of its circumference by two arcuate spaced members 152, 153, spaced on each side of the radial passages 17, having grooves therein forming the balancing chambers 154, 155 connected by passages 159, 161 with the discharge chamber 157 formed by a groove in an arcuate projection 156 extending over the other half of the circumference of the ring 151..The area of the rotor exposed in the discharge chamber 157 is equal to the combined areas of the rotor exposed in balancing chambers 154, 155 so that in operation the rotor is hydraulically balanced. The radial passages 17 each extend into an axial bore 16 in the rotor 14, each bore housing opposed plungers 25 having their outer ends 24 connected by ball and socket joints with swashplate members 53, 54 having surfaces inclined to the axis of the rotor so that on rotation of the latter the plungers are reciprocated and oil is drawn in through the radial passages 17 when they are in communication with the chambers 51 and the space between the projections 152, 153 of the balancing ring and discharged when the passages 17 are in communication with the discharge chamber 157. The output of the pump may be varied by altering the inclination of the swash-plate member 54, which is pivoted on trunnions 101, by manually turning a spindle 126 screwed into a plunger 121 connected to the member 54 by a link 115. The rotor 14 and balancing ring 151 are cooled by the oil in the supply chamber 51.

Filed: 1973-05-08
Abstract: 1426570 Rolling rings RHEINSTAHL AG 8 May 1973 [9 May 1972] 21752/73 Heading B3M A ring rolling mill comprises a pair of rolls 2 and 3 between which a ring 1 is rolled, and a pair of centering rollers whose positions are altered in response to an increase in diameter of the ring during rolling, the rollers being automatically moved to cause re-centering of the ring if the ring shifts laterally relative to a plane through the axes of rolls 2 and 3. The ring diameter is measured by sensors 7 whose outputs are fed to an amplifier 9 and to one or more positioning units 10 coupled to the supporting arms 4 of the rollers. Further sensors 18 measure the relative positions of the rollers and, through a bridge 19, detect any lateral shifting of the ring. The output from the bridge is fed to a frusto-conical roll 15 to adjust the roll speed in a sense to re-centre the ring. The axial position of the roll may alternatively be varied to obtain the same result. The roll is one of a pair which act on the end faces of the ring.

July 18, 1930, No. 21775. [Class 139.] In a recording system, the times at which messages are received are recorded by two switches MJ, HR carrying type-wheels corresponding to minutes and hours respectively. Each minute switch ZC, Fig. 13, changes over momentarily, energizing relays XA, YA. These relays release and, as relay YA is slow to release, a pulse is transmitted to relay MJ during the period that relay YA is up and relay XA is down. Every time relay MJ reaches its 59th position switch mj1 makes contact so that each 60th pulse steps both relays HR, MJ. Keys K5, K3 enable the switches to be set. A pulse received during an actual printing operation is stored by relay U until the printing has been completed. Specification 348,546 is referred to.
Patent GB-1146037-A (GB)
Title: Improvements in or relating to abrasive members
IPC: B24D11/00
Filed: 1966-05-17
Abstract: 1,146,037. Abrasive members. F. L. & J. C. CODMAN CO. 17 May, 1966 [18 May, 1965], No. 21787/66. Heading C4V. An abrasive member comprises body-forming material and a large number of abrasive grains, said body-forming material comprising a large number of discrete pre-formed resilient synthetic foam body particles compressed from their preformed size, said abrasive grains being bonded to adjacent foam body particles bonded together to form said abrasive member with said compressed foam body particles able to resiliently distort when said abrasive member is subjected to working stress. As described one method of making the abrasive member is to place a large quantity of the abrasive grains in a mixer and while the mixer is operating, a first bonding agent in non-cured vicious tacky form is added until the grains are substantially covered, a thickened uncured bonding agent is then introduced in non-cured liquid form, the second bonding agent being more fluid than the first bonding agent, preformed foam body members and more of the second bonding agent are then introduced into the mixer simultaneously and after thorough mixing the mixture is placed in a mould and compressed to a predetermined thickness after which the mould is placed in an oven and baked to cure the bonding material; if desired the addition of the second bonding agent to the mixture prior to the introduction of the foam body members can be omitted. Alternatively the addition of further second bonding agent with the preformed foam body members can be omitted. An alternative method of manufacture is described in which the preformed foam body members have flexible bonding agent applied to them, the foam members and the bonding agent then being subject to compression to form a sheet form layer and to cause the foam bonding members to be pressure bonded together; after the formation of the layer the abrasive grains are applied to one or both faces of the layer and secured by another bonding agent. A plurality of the abrasive layers can then be bonded with similar layers into a sandwich, the exposed edges of the layers defining the working surface of the abrasive member. In either method the bonding agents are chosen so that the bonding agent applied to the grains is less flexible than the bonding agent which contacts the foam body members. The foam body members preferred are made from scrap polyurethane foam from the bedding industry having a density of the order of 2 Ibs. per cubic foot, the scrap being ground into a desired size in the range of ¢ to 1/16 inch balls or cubes. The bonding agent bonding the resilient body members together is preferably more than half by weight of the bonding material and the ratio by weight of the bonding material solids to foam body members is preferred to be of at least one fifth of the weight of the abrasive grains; suitable bonding agents are polyvinyl acetate, polyvinyl butyral and elastomeric polyurethanes.
