Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B7/08
Filed: 1941-06-17
Abstract: 556,549. Hydraulic remote control systems. AUTOMOTIVE PRODUCTS CO., Ltd., and CARLTON, Q. H. June 17, 1941, No. 7665. [Class 69 (ii)] A two-pipe line liquid pressure remote control system of the kind in which a transmitter A and a receiver B coupled by a pair of pipe lines C.D. each comprise a pair of cylinder-and-piston units 66, 72, 73, 74, 75, the pair of pistons 66 being coupled mechanically in each case to move in opposite senses is constructed to maintain correct phase relation between the transmitter and receiver and for returning them to correct phase if necessary. As shown the pistons 66 of the transmitter are operated by connection of links 67 with a lever arm 68 operated by a handle 105, and the cylinders 72, 73 are surrounded by a reservoir 65 from which liquid can pass to either of the pipe lines of low pressure via passages and a non- return valve 88. Passage of liquid from the cylinders is normally prevented by a spring-closed valve 85 to which is attached a rod 93 fitted with a head 94 capable of engaging a guide 96 at the end of the extreme upward movement of the pistons 66. This engagement takes place if the phase is incorrect, and to permit of movement of the upper pistons relatively to the valve rods 93 the links 67 in their upward movement engage spring-controlled stops 97 which permit a greater movement of the right-hand piston 66 than the normal movement corresponding to exact equality of movement of the transmitting piston with the receiving pistons. The transmitting pressure is applied by a rigid stop. When the apparatus is left unused the arm 105 may be moved clockwise far enough to cause the spring stop 97 to raise the plunger of cylinder 73 far enough to open valve 85 and connect the system to the reservoir 65. The arm 105 is locked in this position and so temperature changes are prevented from altering the phase relations adversely during storage. In a modified form the pairs of pistons in the transmitter and receiver are coaxial and arranged in a single long cylinder of uniform diameter. The pistons are operated by rack-and-pinion mechanism controlled by arms fitted with fixed stops and spring stops respectively, and adapted to open valves which connect the cylinders to a reservoir it the devices are out of phase, but not otherwise.

The mark may span all tracks as shown and all 8 of the sensor outputs may be taken to an AND gate 11, or the mark may be outside all the diagram tracks and sensed by a special sensor, or it may be made on some of the tracks and be used to provide information regarding the type of record to be analyzed, e.g. whether it spans an 8, 12 or 24-hour recording period, and to activate a corresponding pulse generator output 4. To avoid errors owing to spurious marks on the disc 1, when a leading edge of a mark N is sensed, a monostable 22 is triggered to enable a gate associated therewith for a period only slightly longer than that required for the mark to travel across the sensors, the condition at 11 resulting in an output at the trailing edge.

IPC: B62D1/19
Filed: 1968-02-16
Abstract: 1,171,573. Safety steering columns. EATON YALE & TOWNE Inc. 16 Feb., 1968 [17 Feb., 1967], No. 7734/68. Heading B7H. [Also in Division F2] A steering assembly for a vehicle comprises a steering shaft member 24 carrying a steering wheel 30, support means for supporting the steering shaft member and steering wheel in a predetermined position and preferably explosive fluid pressure means for effecting movement of the steering shaft from the predetermined position. The steering wheel may be moved by the fluid pressure either towards or away from the bottom end of the assembly. In a first embodiment, an explosive charge 48 is disposed in a chamber 44, formed between a housing 32 and an annular flange 42 secured thereto and an upper steering shaft part 20 and a piston 46 secured thereto, and in a collision of a vehicle including the steering assembly the charge is set off moving the piston 46, steering shaft part 20 and steering wheel 30 outwards relative to the housing 32 and a lower steering shaft part 22 until a conical portion 50 of the shaft part 20 engages and wedges within the flange 42. A deformable part 52 of the housing is collapsible to absorb energy when a driver is thrown against the steering wheel whether or not the explosive charge has been set off. The steering assembly in Fig. 5 is shortened by the explosive charge 98 which acts on an outwardly extending portion 96 of a housing sleeve 90. The steering shaft comprises two parts 70, 72 joined by shearable pins 74 and energy is absorbed by the folding back of portions 88 of a metal tube mounted coaxially of the sleeve 90. To facilitate the folding back of the portions 88, which comprise U-shaped outwardly extending- tabs secured to the sleeve 90 before deformation, the tube is provided with longitudinal grooves 92 (Fig. 7) where the tube tears on deformation. In Fig. 11, a further embodiment is shown which has a deformable energy-absorbing member 125 at the top of the housing 100 and a conical section 134 at the bottom of the lower shaft part 110 on which the originally cylindrical end 136 of the upper shaft part 108 wedges to prevent rebound of the steering wheel when the explosive charge 124 has moved it downwards. As shown in Fig. 14, the steering assembly comprises shearable connections 162, 170 and 178 respectively between the two shaft portions 160 and 161, the housing portions 166, 168 and tubular gear change members 172 and 174. A snap ring 181 normally retains the piston 180 on the shaft portion 161, but, should the lower end of the shaft portion 161 be stopped by a steering box before the upper end 194 of the shaft portion 160 wedges on the conical portion of the shaft portion 161 when the explosive charge is set off, the snap ring shears permitting the piston 180 to engage with the shaft end 194 to prevent rebound of the steering wheel. The shortenable steering assemblies may be used with a bag which is rapidly inflated during a collision to cushion forward movement of a vehicle occupant.

Title: Improvements in and relating to the production of hydraulic cement
IPC: C04B7/12
Filed: 1933-03-14
Abstract: A hydraulic cement is made by mixing and grinding together a finely ground clinker material containing tricalcium silicate, e.g. Portland cement, and carbonate of lime which has been artificially dried and contains less than .5 per cent of moisture. The carbonate is preferably ground to pass an 8-mesh sieve and so to be relatively coarse as compared with the clinker.  The proportion of dry carbonate is preferably 8 parts of carbonate to 1 of free calcium oxide in the clinker.  In an example limestone or other calcium carbonate is crushed to pass a one-inch mesh, dried so that not more than .5 per cent of moisture remains, and ground to pass an 8-mesh sieve.  The ground dry carbonate is then mixed with clinker of a fineness to have not more than 1 per cent residue on a 76 mesh sieve and not more than 10 per cent on a 180 mesh sieve.  The mixture is then ground until the whole passes through a 50-mesh sieve.  Specifications 345,103 and 385,664 are referred to.
