[Classes 122 (i), 122 (ii), and 122 (iii).] A compound or multiple-expansion engine using high-pressure, highly-superheated steam is provided with piston slide valves controlling the inlets and auxiliary exhausts from the cylinders respectively, the main exhausts are controlled by the main pistons. The engine may have one or more L.P. cylinders, or two H.P. and two L.P. cylinders. The valve of the H.P. cylinder in a compound engine is provided with outside admission, and the L.P. cylinder with inside admission. The engine, Figs. 1, 2, has main pistons b, b<1> controlling the main exhaust from the cylinders a, a<1>. The H.P. inner valve edges n control the auxiliary exhaust and determine the compression. The outer edges of the L.P. valve control an auxiliary exhaust to compression chambers s, t arranged at the ends of the valve-chest. Pipes x, y of small diameter, which serve only for the removal of condensed steam, are connected to the condenser. Steam is supplied to the H.P. chests across the cylinder covers to heat them. The construction permits a short connection with small cooling area between the H.P. exhaust and the L.P. inlet. The valve-chests which are arranged at right angles to the shaft, permit a close arrangement of the cylinders. The valves are relatively small and are dimensioned only for inlet steam.

Title: Improvements in washing machine water softening arrangements
IPC: B01J49/80
Filed: 1964-08-04
Abstract: 1,029,526. Dishwashing machines. LICENTIA PATENT - VERWALTUNGS G.m.b.H. Aug. 4, 1964 [July 22, 1963], No. 30742/64. Heading A4F. A water softener in the supply line of a dishwashing machine is regenerated during a washing operation. When an electromagnetic valve 3 is energized by programme switching means 13, water passes from a supply line 2 via the valve 3, a water softener 5, and a pipe 6 to the washing and rinsing compartment 1. On the attainment of a predetermined water level in the compartment 1 a pressure operated switch 12 is actuated to close the valve 3 and open an electromagnetic valve 7 so that water flows through a pipe 8 and a salt supply container 9 to proceed as saltsolution to the water softener 5 to displace the softened water therein. Upon a predetermined higher liquid level being reached in the container 1 the switch 12 is actuated to close the valve 7, and the washing operation proceeds whilst the salt solution regenerates the softener 5. An alternative embodiment is described in which programme switching means initiates simultaneous water supply through two electromagnetic valves in parallel, one for supplying unsoftened water to the washing compartment, and the other for supplying water through the regenerating device to the water softener.

Title: Method of and machine for winding weft cops
IPC: B65H54/14
Filed: 1959-09-11
Abstract: 936,183. Automatic looms combined with bobbin winders. W. REINERS. Sept. 11, 1959 [Oct. 13, 1958], No. 31086/59. Classes 120 (3) and 142 (2). An automatic winding machine attached to an automatic bobbin changing loom supplies the loom with slub- and knot-free bobbins which may be only partly full of weft; if a knot or slub is encountered during winding, the thread breaks in advance of it, the knot or slub is cut out, and winding restarts on an empty bobbin. In the embodiment shown in Fig. 1, the last few turns wound before the bobbin is full or before the thread breaks are unwound and rewound on the nose of the bobbin as a tip bunch; alternatively, the end may be sucked into the bore of the bobbin. The wound bobbins roll down a feedway 7 leading to the bobbin changing mechanism 3 of the loom. A feeler 6 checks for the presence of the tip bunch, any bobbins without one being returned down a shoot 23 to join exhausted bobbins ejected from the loom on a slideway 22 leading to a conveyer belt 20. There may also be a feeler to reject bobbins wound with too small an amount of thread. At the top of the conveyer 20, the bobbins are discharged into a magazine 10; feeler 17, 18 interrupt winding when the number of bobbins in the magazine is below a predetermined minimum. When a wound bobbin is doffed, a transfer arm 19 takes the next bobbin from the magazine to the winding head 12. The residue of thread is removed by rotating the bobbin in the unwinding direction and collecting the residue by a suction device. The bobbin is then rotated in the winding direction and wound with thread from a supply 15; the thread passes through a device 14 which traps a slub or knot so that the thread breaks between the device 14 and the winding head. In an alternative arrangement, a tip bunch is not formed, but between the winding machine and the loom the bobbin is gripped in a driving head which rotates it in the unwinding direction for a few turns to enable a suction nozzle to draw off the end of the thread and deposit it in a clamp which holds it until the bobbin has been inserted into the loom shuttle.

Title: Improvements in or relating to a pressure relief plug for a pressure cooker or the like
IPC: A47J27/09
Filed: 1948-12-01
Abstract: 663,780. Pressure relieving devices for fluids ; valves. EKCO PRODUCTS CO. Dec. 1, 1948 [June 15, 1948], No. 31128/48. Class 135. A pressure relief plug for a pressure cooker or the like comprises a resilient disc member 18 adapted to be mounted in an opening 20 in the cover 12 of the cooker and a closure member 29 axially movable under fluid pressure in the cooker into sealing engagement with an aperture in the disc member through which it extends, the disc member 18 being distortable under a predetermined excess pressure whereby a valve portion 34 of the closure member is forced through the aperture to release the excess pressure. The aperture comprises a circular upper portion 27 and a substantially elliptical lower portion 28 separated by a shoulder 25. The closure member 29 also has a head portion 31 with a transverse slot 33 and a flange 32 which engages the disc member when the pressure in the cooker is at atmospheric pressure or less. In this position air may pass out of the cooker during an initial heating period or into the cooker to prevent the formation of a vacuum when the cooker is cooling off. Below the valve portion 34 is a stem portion 36 bearing a retaining disc 37 which engages the underside of the disc 18 to prevent the closure member 29 being expelled from the disc member when the predetermined excess pressure is exceeded. The disc member, which is of rubber or a synthetic rubber such as neoprene, has upper and lower flanges 22, 23 whereby it is normally held in the opening 20, the upper flange 22 lying in a recess 21 and having its lower face substantially in the same plane as the shoulder 25. If the aperture 27 becomes clogged with particles of food or other matter, or if for any other reason, the pressure relief means constituted by the valve portion 34 and the deformable flange 26 of the disc member fails to act, the complete disc member 18 with the closure member 29 attached thereto is blown out of the opening 20 at a predetermined higher pressure.

Title: Improvements in or relating to axial flow multi-stage compressors
Inventor: CRAIG HUGH ROBERT MORTON
IPC: F04D19/02
Filed: 1956-10-12
Abstract: 849,662. Axial-flow compressors. ENGLISH ELECTRIC CO. Ltd. Oct. 4, 1957 [Oct. 12, 1956], No. 31136/56. Class 110 (1). In a multi-stage axial-flow compressor, one or more intermediate stages are dimensioned so as to operate at the lowest loading of all stages, i.e., with the highest absolute value of negative angle of incidence compatible with efficiency of the blading thereof. This reduces the tendency towards surging. Fig. 1 shows some intermediate stages of an axial-flow compressor, initial and final stages being omitted. The stator S has an inward projection, of substantially trapezium cross-section, over the extent of the stator blades 3, 5 and 7, whereby the stator blades 5 and rotor blades 6 of one stage are shorter than the blades 7, 8 of the following stage. The resultant decrease in the flow passage area increases the absolute velocity of the air, thereby reducing the angle of incidence at the blades 6 to a negative value. The inward projection on the stator may be replaced or supplemented by an outward projection on the rotor. A further alternative or additional way of producing a negative angle of incidence is to increase the blade stagger at the stages concerned.

Abstract: 849,390. Determining physical qualities of materials. MINISTER OF NATIONAL DEFENCE OF HER MAJESTY'S CANADIAN GOVERNMENT. Oct. 6, 1958 [Oct. 2, 1957; July 2, 1958], No. 31869/58. Class 37 The refractive index of air is determined by generating two radio frequency signals, the frequency of one signal being controlled by a multiplate capacitor containing the air under test; both signals are transmitted to a remote point where their difference is determined. Fig. 1 shows a block diagram of a system for determining the atmospheric refractive index at different heights. The refractometer 10, referred to later is carried by a balloon tethered by a cable 21 to a winch. The two signals are radiated by aerials 14, 15 and picked by a receiver which records the difference which is dependent on the refractive index. The recorder 19 is also fed with the position of the balloon as obtained from a tracking radar 18. Fig. 7 shows a circuit of a Clapp type oscillator A and a buffer amplifier B forming the refractometer 10. The oscillator A is alternately tuned by a reference capacitor 27 and by a capacitor 28 containing the air under test. The capacitor 28 may have plates of nickel-iron alloy having a waterrepellant coating and quartz spacers to minimize the temperature co-efficient. The two alternate signals, having a frequency of approximately by 5 mc/s, are picked up by a super-heterodyne receiver, Fig. 8, and made to beat with a signal from an auxiliary oscillator 41 to provide an audio frequency modulation. The output of the audio frequency amplifier feeds a discriminator which provides a fluctuating D.C. output dependent on the frequencies of the alternate signals, from which the refractive index is obtained. In an alternative arrangement, Figs. 3, 5 (not shown) the refractometer 10 contains two known Clapp type oscillators both operating continuously and feeding separate buffer amplifiers. The auxiliary oscillator 41 is then omitted and the audio amplifier is made tunable to the difference frequency. The Specification also refers to known microwaves refractometers comprising a sealed resonator and a resonator containing the tested air. Reference is also made to a known method of determining refractive index from measurements made by meteorological instruments.
