Inventor: WALKER DANIEL NORMAN
IPC: B23P15/00
Filed: 1944-12-22
Abstract: 650,437. Turbine blades. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Dec. 22, 1944, No. 17626/48. Divided out of 650,424. [Class 110(iii)] In an axial flow gas turbine rotor having hollow sheet metal blades mounted thereon by means of root walls constituting continuations of the blade walls, at least one of the walls lies outside of the flank of the rotor element and defines therewith an air duct communicating with the inside of the blade. Hollow sheet metal blades are defined as blades made of thin flat sheet or thin tube. The blades shown in Figs. 1 and 3 are attached to the rotor 2 in the manner described in Specification 650,424. In the arrangement shown in Fig. 1, the rim of the wheel 2 is indented at 6 to afford residence to the rotor rim. This indentation is, according to the present invention, carried to a point radially within the lower edge of the blade skirt 7 to provide an inlet for cooling air to the interior of the blade 1. In the arrangement shown in Fig. 3, the blade root has a third wall 4a spaced from the flank of the rotor by indentations 8 so as to form a duct 9 leading into the interior of the blade. In another modification the cooling air passage is formed by pressing, a channel in the wall 4a. A fourth root wall also having a channel pressed in it may be provided. The invention is not limited to blades attached by axially disposed slotted anchorages in the rotor wheel. The use of peripherally extending root walls suitably secured to the. axially exposed face of the rotor is referred to.

Title: Pulse amplifier
IPC: G11C11/38
Filed: 1963-05-03
Abstract: 1,007,958. Pulse amplifiers. RADIO CORPORATION OF AMERICA. May 3, 1963 [June 4, 1962], No. 17670/63. Heading H3T. A pulse amplifier comprises an input transistor 10 connected to supply forward bias current for a negative-resistance diode 16 of the voltage-controlled type, the amplitude of the current being within the first stable-operating range. Another source of current is connected to the diode 16 via a switch 54 and isolating diode 56, the switch being controlled by a strobe pulse which resets it and holds the diode 16 in its first stable state during continuance of the input pulse. The input pulse must have sufficient amplitudes to trigger transistor 10, and then the amplitude and width of the output pulse are controlled by the transistor 30 and the strobe pulse respectively. Large amplitude input signals can be dealt with by including a current-limiting diode or transistor network (Figs. 3, 4, not shown).

Patent GB-653863-A (GB)
Title: Clothes washing machine
IPC: D06F13/02
Filed: 1948-07-05
Abstract: 653,863. Washing and drying machines. TRIGGS, W. W. (Apex Electrical Manufacturing Co.). July 5, 1948, No. 18065. [Class 138 (ii)] [Also in Group II] A clothes washing machine includes a container 26 arranged to be given a wobbling movement for washing and a rotating movement for extracting water from the clothes, inner and outer co-axial driving-shafts 22, 16, a counterweight 19 on the outer shaft to counterbalance forces created by the wobbling movement, and driving means arranged to rotate the outer shaft for washing and to rotate the inner shaft and hold the outer shaft for extracting. A second counterweight 21 may be secured to the outer shaft diametrically opposite, and spaced downwardly from the first. The two weights rotate during wobbling of the container 26 but are held against rotation during spinning so that undesirable unbalance does not occur. The inner shaft is employed to hold the basket against rotation during the washing period, and is rotated to effect spinning of the basket. A plate 46 is keyed to the outer tubular shaft 16 and is urged downwardly by a spring 47, the lower face of plate 46 having an annular strip 48 of friction material affixed thereto. A second plate 49 is keyed to the inner shaft 22 and is pressed upwardly by a spring 51, the upper face of plate 49 having an annular strip of friction material 52 affixed thereto. During the washing period the parts are as shown in the drawing, the friction material 52 of the lower plate being held in engagement with a lower flange 44 of a housing 42 so that the inner shaft 22 and therefore the basket 26 will be prevented from rotating. A pulley 36 freely rotatable on shaft 22 is driven through a belt 34 by an electric motor 31 and can be moved axially a slight distance on the shaft 22 by means of a shifting fork 39 mounted on and secured to a shaft 41 which may be rocked manually or automatically. The pulley 36 is lifted upwardly to force upper plate 46 out of contact with an upper flange 43 of housing 42 so that the outer shaft is free to rotate. Friction material 37 on pulley 36 engages that on plate 46 so that shaft 16 is rotated when the motor is started. An inclined bearing 18 is fixed to the top of shaft 16 and carries a stub shaft 24 which is thus caused to move in a conical path and wobble the basket. On completion of the washing period, pulley 36 is moved downwardly by the fork 39 so that plate 46 is pressed against flange 43 and shaft 16 held against rotation. Friction material 38 on the lower face of pulley 36 then engages the friction material of the lower plate 49 so as to move the plate 49 out of contact with the flange 44 and cause shaft 22 to be rotated. Thus the housing of the inclined bearing will be held stationary and a spinning action will be imparted to the basket through a universal joint 25. In a modification, instead of moving pulley 36 axially, it may be held against axial movement and the same results achieved by moving the housing 42 or the flanges 43, 44 axially. Specification 636,528 is referred to.
