Title: A process for the manufacture of artificial stones from lime
IPC: C04B28/10
Filed: 1931-11-10
Abstract: Artificial stones are made by slaking lime with a large quantity of water, adding filling materials such as pulverulent calcium carbonate, pulverized stone or infusorial earth, mechanically removing the greater part of water from the mixture, drying, grinding, moulding and finally treating with carbonic acid.  Hard material such as silicon carbide or quartz may be added to the mixture before the moulding.

A fibre fleece is finished by subjecting it to a smoothing and felting treatment in its own plane in conjunction with a heat treatment. The fleece 5 passes around a cylinder 2 rotatably mounted in a housing 1 and having a highly polished surface. Pressure rollers 3 are located about the periphery of the cylinder 2 and are rotatable at higher peripheral speeds than that of the cylinder and at progressively increasing peripheral speeds. The rollers 3 or the cylinder 2 is vibrated transversely to the feed direction. The rollers 3 are or the cylinder 2 is heated and the cylinder or the rollers may be cooled. The gaps between the rollers 3 and the cylinder progressively decrease in the direction of feed of the fleece 5. Guide rollers 4 are provided. An impression roller (not shown) may be applied to the fleece 5 after it has left the last roller 3.

Title: An auxiliary wing for aircraft
IPC: B64C21/08
Filed: 1937-11-17
Abstract: 494,863. Controlling aircraft. BLUME, W., and ARADO FLUGZEUGWERKE GES. Nov. 17, 1937, No. 31577. [Class 4] An auxiliary aerofoil B, Fig. 2, is nested in a recess in the trailing part of a wing A and is adapted to be swung downwardly and rearwardly to a position in which it acts as an extension flap and in this position is adjustable about a spanwise axis for purposes of lateral control. Aerofoil B is carried by double-armed levers c, Figs. 3 and 4, each pivoted at one end on a shaft a carried by wing ribs Ra and pivoted at the other end on a shaft b carried by aerofoil ribs Rb. The upper arm of lever c is linked to a lever o on an operating shaft p such that rotation of this shaft causes movement of the aerofoils of both wings through the position Stx to the position Ste. Angular setting of the aerofoil is controlled by a chain r connecting sprocket f fast on shaft b to sprocket e fast on axle a. Sprocket e is integral with a lever d linked to aileron control gear. The number of teeth on sprockets e, f is unequal so that during rearward movement to position Ste to angle of incidence of aerofoil B is increased relative to that of the main wing A. Lateral control in high speed flight is effected by partial rearward movement of one or other flap from the nested position and not by the aileron control gear.

Abstract: 1486812 Controlling converters NEW ZEALAND INVENTIONS DEVELOPMENT AUTHORITY 23 Aug 1974 [3 Sept 1973 10 July 1974] 31707/76 Divided out of 1486811 Heading H2F A method of synthesizing a pulse width modulated waveform comprises generating a first square wave having a variable frequency, generating a pulse waveform, the duration of which is independent of the frequency of the square wave and occurring at least once in each square wave half-cycle, inverting said pulse waveform, enabling said inverted waveform for a predetermined fraction of each square wave half-cycle and chopping said square wave with said enabled waveform to produce said pulse width modulated waveform. As shown in Figs. 1 and 2, a variable frequency clock pulse generator 10 feeds a twisted ring counter 12, the various outputs of which are supplied to three exclusive OR gates 18a ... 18b. The generator 10 also feeds a chopping pulse generator in the form of a variable period monostable multivibrator 14 producing pulses y which are inverted and fed to AND gates 16a ... 16c so as to control the outputs of the exclusive OR gates 18a ... 18c. Further exclusive OR gates 20a ... 20c provide waveforms V1 ... V3 to control the six switching devices S1 ... S6 of a three-phase inverter 19 supplying an A.C. motor with voltages V L1  ... V L3  (Fig. 2) such that, after integration in the motor, the currents are substantially sinusoidal. The speed of the motor is adjustable by varying the frequency of generator 10 which at the same time adjusts the width of the chopping pulse and hence the effective magnitude of the motor voltage such that the voltage α frequency.

A method of manufacture is described in which the rings 6, 7 have initially an axial length greater than the depth of the recesses and are guided between two annular plates clamped to the gear wheel, outlet holes being provided in the plates to control the pressure produced in the plastic material which is compressed as the rings are inserted. The plastic material may then be treated (e.g. vulcanised) and after removing the plates the projecting parts of the rings may be turned off. The rings may be axially slotted (Fig. 3) so that in the turning operation the connecting portion is iemoved leaving the ring in separate segments.

Abstract: 459,064. Door fastenings. BROWNHILL, S. W. J., Penrhyn, Prestwood Road, Wednesfield, Staffordshire. Nov. 22, 1935, No. 32369. [Class 44] Doors of railway coaches and the like are secured by the projection of bolts B through guides C in the floors of the coaches and their engagement in boxes on the doors. A shaft S is mounted beneath each coach floor and a bolt B is pivoted to an arm A mounted on the shaft at each door. A metal box is screwed to the inside of the door and has a hinged lid F secured by a sliding bolt G. An aperture H in the box wall permits the door to be closed when the bolt is projecting, and after the closure of the door, the flap J is operated by a spring K to close the aperture. To move the bolts B to their locking position a solenoid is energized, and this operates its core on an arm attached to the shaft S, which then rotates to lift the bolts B into the boxes. When the solenoid circuit is broken the weight of the parts, aided by springs if required, restores the bolts to the free position.
