Abstract: 664,055. Scale-model testing of ram jets. LEDUC, R. March 10, 1949 [March 12, 1948], No. 6540/49. Class 4. Apparatus for scale-model testing an aerothermodynamic duct in a wind tunnel with simulation of the effect of combustion comprises a model 3 of the duct in combination with a coaxial member 6 mounted in that portion of the model corresponding to the combustion and exhaust zones of the actual duct, so as to reduce that part of the model to an annular passage, the member 6 extending downstream from the model without abrupt change of section for attachment at 7 to a mounting remote from the model so that the forces to which it is subjected are not transmitted to the tunnel balance. At any axial section the ratio of the area of the annular passage to the total internal area of the corresponding section of the actual duct is equal to the square root of the ratio of the densities of the heated air at the temperature obtaining at that section in the duct with combustion and of air at ambient temperature. Under such conditions the mass flow of air at ambient temperature through the model duct is the same as it would be without the member 6 in place if combustion were taking place in the model, having regard to the requirements of dynamic and thermodynamic similarity between the model and full size duct.

ANDREW MILLS, Ltd., 34, St. Andrew Road, Walthamstow, both in London. March 4, 1933, No. 6627. [Class 81 (ii).] An apparatus for the manufacture of sanitary towels and like absorbent bandages which consist of an absorbent filling arranged within a tubular cover, is characterized by a hollow mandrel 8 arranged between and held by conveyer bands 3, 5, 7, and formed with a part spherical head 8<1> constituting an abutment preventing forward movement of the mandrel. A knitted or gauze tube 10 is drawn over the mandrel from spool 9 by means of the conveyer bands, and encloses the filling 12 introduced into the open end of the mandrel. The completed towel is cut by severing means 13, a portion of the cover being left empty at either end. The severing means may consist of two blades 13 hinged behind a diaphragm 14, and actuated through links 16 connected to a hinged lever 17, 19, Fig. 3. The shears may be pedal operated, but hand operation is preferred. The introduction of the pieces 12 into the mandrel may be effected by hand, and the tube pulled by hand thereover from the accumulated pile held up by resilient checking arms 11, Fig. 1. For automatically introducing the filling pieces, there is provided a supply box 28, Fig. 11, into which are periodically fed from conveyer 31 the filling pieces 12. The bottom of the box 28 is formed of two slides which, through cams and rocking levers, are periodically opened, thereby depositing the filling piece into a feeding drawer 22. After a towel has been severed, this drawer is moved forward by a lever 23, actuated by cam 24, and carries with it the slide 25. At the extremity of the forward travel thereof, a stop 27 engages the rocking arm 26 connected to the slide, retaining it while the drawer 22 and arm 23 return. The filling 12 is thereby deposited in a recess 21 in the bottom wall of the mandrel directly on to the tubular cover 10, which, after withdrawal of the stop 27 and consequent return of the slide 25, is moved forward by the conveyer bands to enclose the filling. The towel is severed by shears 13 which, with all of the other operation parts, are suitably synchronized.

Title: Improvements in or relating to valves for controlling the flow of liquids
Inventor: FRASER JOHN
IPC: F16K31/34
Filed: 1953-03-11
Abstract: 732,282. Fluid-pressure servomotor-control systems. AVERY-HARDOLL, Ltd. March 9, 1954 [March 11, 1953], No. 6751/53. Class 135. In a valve 29, Fig. 2, e.g. for filling tank vehicles, of the type which is opened by liquid inlet pressure at 14 and closed by liquid pressure in a chamber 36 under the control of means responsive to tank liquid level, escape of liquid from the chamber is controlled by a relay valve 75, 85, closed in two stages as a float 19, Fig. 5, rises; and admission of liquid to the chamber is determined by the position of the valve 29. Inlet pressure raises the valve against a spring 35 and lifts a shoulder 49 off a ring 48 so that liquid flows via groove 47 and port 46 into tube 43 secured to the valve casing 12 by arms 39 and on which the valve slides, and via port 45 into a control chamber 36 behind the piston 27 carrying the valve, into a pipe 17, 18 and into the tank 10 via ports 67. When the float rises to a certain height its rod 68 allows a valve 75 to close on its seat 78 and restrict flow in pipe 17 to a notch 79 so that pressure in the chamber 36 increases and valve 29 moves downwards to restrict inflow to the tank to a narrow passage around seat lip 34 and also to throttle the flow through valve 48, so that inflow to the chamber 36 equals the flow in pipe 17. As the float rises to its final level, its rod 68 breaks contact with valve 75 and closes the ring valve 85 on to its seat orifices 83 so that valve 29 closes on to the rings 32 and 48. The tank is drained by opening valve 29 through a lever 55.

Abstract: 1,122,041. Switching circuits. STAAR S.A. 17 Feb.,1966 [16 Nov., 1965], No. 6997/66. Heading H3T. [Also in Division G5] In an arrangement for automatically stopping a tape recorder-player, the stopping of rotation of the tape take up or drive spool is monitored. In one system (Fig. 1) a capacitor C1 is initially charged from the supply with the switch 17 in the position shown, and the position of the switch is changed when play or record is started to connect contacts I and III. The voltage from C1 applied to the base of transistor T1 causes T1 to conduct and consequently T2, enabling the drive motor 14 and warning light 15 to be energized. The rotation of the tape spool 1 causes a cam 2 to repeatedly change the connections between the finger 9 and the fingers 8 and 10, to repeatedly charge and discharge capacitor C2. In discharging, C2 recharges C1, so that the transistor circuit remains switched on and thus the drive motor remains energized. When, at the end of the tape, the spool stops rotating, the repeated charge and discharge of C2 ceases and C1 discharges completely, so that the transistor leak circuit cuts off and the drive motor is de-energized. In an alternative arrangement (Fig. 4, not shown), the charge and discharge arrangement keeps a monostable circuit in one state. When the charge and discharge ceases, the monostable circuit changes to its other state, causing a relay controlling the supply circuits to be operated and the supplies to the drive motor to be disconnected.
