Abstract: 700,861. Ironing-presses. SHIPPEY, L., and DENISON, A. Dec. 17, 1951 [Nov. 27, 1950], No. 28906/50. Class 138 (2) In a laundry press having a pair of work tables 2, 2 mounted on a turntable for rotation into position beneath a pressing head, and a compressed air operated ram for forcing the work tables in turn into contact with the head, rotation of the turntable is effected by means of a piston located in a cylinder 1 which is pivotally mounted on a fixed pillar 1a, the piston having a piston rod whose exposed end is connected to one end of a link 3 pivotally mounted upon a shaft 4 which engages the shaft of the turntable to effect rotation thereof, the cylinder 1 being connectible to the main air supply line upon operation of a foot pedal 21 to exhaust the ram operating cylinder of the machine. The link 3 carries a spring-loaded latch 6 which engages a double-sided cam 5 on the shaft 4. On the outward stroke of the piston the latch 6 rotates the cam 5 and hence the turntable whose momentum carries it through 180 degrees. A spring (not shown) returns the piston to its initial position, the cylinder 1 being connected to exhaust by a valve 8 and connection 7. The valve 8 is opened and closed by stops 10 carried on a rod 9 and engaged by a finger 11 on the piston rod. When the pedal 21 is depressed to exhaust the ram operating cylinder, a valve 14 is opened to permit air to enter the cylinder 1 to rotate the turntable and also to enter a cylinder 16 to operate a check plate 17 which is adapted to engage the projecting part of diametrically opposed brackets 18 mounted on the underside of the turntable to stop the same. On releasing the pedal 21 the cylinders 1 and 16 are exhausted and the ram operated to lift one of the work tables 2 into contact with the pressing head. An adjustment valve (not shown) in the air line to the cylinder 1 controls the rotation speed of the turntable.

Title: Improved arrangements for balancing hybrid connections
IPC: H04B3/40
Filed: 1957-09-13
Abstract: 818,124. Impedance balancing networks. STANDARD TELEPHONES & CABLES Ltd. Sept. 13, 1957 [Sept. 14, 1956], No. 28913/57. Class 40 (8). [Also in Group XXXIX] In a hybrid arrangement in which capacitances C1 ... C4 are included in the transformer to form a high-pass filter in order that noise and/or low signalling frequencies may be excluded, the series condenser or inductance of the balancing network is omitted, compensation being effected by modification of the values of the first mentioned capacitances. In Fig. 3 a normal arrangement would be realized if C8 were omitted and a series capacitor C5 (not shown) were inserted in the lower leg of the balance arm. Since this latter condenser is in series with C2 its omission would make the capacity of this arm too large. Compensation is effected by increasing the capacity of the other arm by shunting an additional condenser C8 across C1. In the event that the presence of the line transformer T3 so increases the effective line inductance that a series inductance would normally be required in the balance network, this inductance may be omitted, compensation being effected by connecting the additional condenser across C2. Conventional switching means for connecting C8 across one or other of C1 and C2 is provided. Condenser C8 is small and can thus be easily made of the variable type as is normally required.

Title: Tubing for use in forming ducts in concrete structures
IPC: B28B7/32
Filed: 1951-12-12
Abstract: An inflatable tubular core is made of three concentric tubes The innermost tube is made of rubber or like elastic material, the middle tube is made of flexible material such as textile fabric and is treated with a lubricant, and the outermost tube is made of rubber or like elastic material.  The outside diameter of the innermost tube is less than the inside diameter of the middle tube, and the inside diameter of the outer tube is less than the outside diameter of the middle tube.  When the innermost tube is inflated through the usual valve, the middle tube takes the diameter and shape it is designed for and the outermost tube expands and assumes the condition of a stressed skin over the unstretched middle tube.  The function of the lubricant is to enable the middle tube to slide relative to the other tubes, whereby folds are avoided.  The lubricant may be vegetable oil or hydraulic brake fluid.
