Abstract: 1,230,800. Top-roller' carrying and loading arm. W. SCHAEFFLER and G. SCHAEFFLER [trading as INDUSTRIEWERK SCHAEFFLER OHG], 17 Oct.,' 1968 [17 Oct., 1967; 9 Aug., l968], No.'49380/68. Heading DID. In a drawing frame of the kind in which the plane'passing through the axes of the feed roller pair 7,'8 is inclined to the plane passing through the axes of the other roller pairs 10, 11 and 12, 13 which are parallel, the force load-' ing the feed roller pair acts in the plane passing through their axes and at right angles to these axes. A top-roller carrying and loading arm - 3 is centrally loaded in direction 4 and has pressure saddles 15, 21 and 24 for the pairs of rollers. Pressure saddle 15 is pivotally mounted on pin 16 in supporting part 17 which is connected to the carrier -1. A helical spring 20 bears against the supporting part and acts on the saddle 15 so that the loading force on roller 7 resulting from force 4 and the force of spring 20 acts in the desired plane. The other pressure saddles 21, 24 may have supporting springs 23 so that the loading is not determined solely by the central loading force 4.

Abstract: 1,239,001. Speech synthesizers. ELEKTRONISCHE RECHENMASCHINEN-WIS. SENSCHAFTLICHER - INDUSTRIEBETRIEB - KARL - MARX - STADT VEB. 27 Feb., 1969, No. 10649/69. Heading H4R. In a speech synthesizer, vocoder channel filters are arranged to be fed from tappings along one edge of a potential field, i.e. a block of resistance material or an electrolytic bath, with the excitation function signal applied to a point on the field selected by a switching matrix in which one co-ordinate is the formant frequency and the other co-ordinate the formant shape or bandwidth. Each formant may be selected by a respective switching matrix to feed an excitation function signal into respective points on a common potential field. The signal fed to the common point of the switching matrix may also be derived via a second potential field arrangement to provide more control over the amplitude of the resulting formant derived from the system. Fig. 4 shows the switching matrix 19 to the common points of the switches X of which is applied the excitation signal from a source 12 via resistors 17. The crossing point rendered conductive is selected either manually or by feeding selecting signals into counters 18. The particular cross-point rendered conductive feeds the excitation signal to a point 27 in the potential field 20, Fig. 5, to one edge of which are connected the synthesis filters 22 via resistors 21. The resistors 17 and 21 may be replaced by a second potential field device to provide formant amplitude control, with different feed points providing alternative types of excitation signal.

Abstract: 1,251,733. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 10 Oct., 1969 [16 Oct., 1968], No. 49815/69. Heading H4K. [Also in Division H1] In an end-marked self-seeking multi-stage crosspoint switching network, each matrix is a monolithic semi-conductor device and crosspoints of successive stages are adapted to fire at successively lower energy levels. The crosspoints may be PN PN diodes, each incorporating a Zener characteristic as shown in Fig. 4. The main feature of this characteristic is the flat top to the curve providing a constant voltage output with level and duration selected to operate a predetermined number of crosspoints of the subsequent stage, each subsequent stage being constructed to respond for a shorter duration and at a lower level than the previous stage. Each matrix comprises a substrate 50 having an epitaxial layer 51 grown thereon. Through successive oxidation, etch, and diffusion steps, a number of P and N layers are diffused into the epitaxial layer to form PN PN diodes. Conductors 52 are then chisel bonded to the diodes to form matrix connections. The efficiencies of the junctions in different switching stages is varied to provide the switching levels and the efficiencies of the junctions within a single PN PN diode may be varied to provide the Zener characteristic. The efficiencies of the junctions may be varied by varying the thicknesses of the individual layers of the PN PN diodes and by providing the epitaxial layer with an internal resistivity characteristic reducing smoothly from a high resistance at an isolating boundary layer 61 to a low resistance at the top surface 62. Coupling between successive matrices is effected over a wire formed by metallized deposition or as a diffused resistance element having distributed capacitance and resistance characteristics matching the needs of the diodes.

[Also in Division G1] An industrial pallet or stillage truck comprising a body 10 having a power unit, and hydraulically operated pallet lifting forks 15, includes a gauge 32 for sensing the pressure in the hydraulic system for the forks and calibrated in units of weight whereby a direct reading of weight of the load on the pallet is obtainable when the hydraulic system is momentarily placed in communication with exhaust to relieve inherent stresses in the system. The forks 15 are raised by hydraulic rows 18 pressurized from a motor-driven pump 21 upon depression of a button 25 on a control handle 13, the motor being de-energized by a limit switch operated when the forks reach their upper position. A normally closed solenoid valve 27 may be momentarily opened by momentary depression of a button 26 to momentarily exhaust the rows 18 to a fluid reservoir 8 whereafter the true load on the forks may be read on the gauge 32, continued depression of the button 26 causing the forks to completely lower the load. In the modification of Figs. 3 and 4 (not shown), a normally open solenoid valve is placed in the ram hydraulic system in series between the normally closed solenoid valve and the reservoir, the two valves being simultaneously energized by a single button depression, during which energization the two valves will be momentarily open together to give the desired pressure gauge reading. The electrical circuit is arranged such that the two said valves can only be energized if the limit switch has been operated when the forks reach their upper limit of travel.

The surface of ring 36 remote from the cylindrical bearing surface engages a bearing housing 21 and has a non-cylindrical surface 35 which enlarges in size in the direction of the flange 26. The ring 32 is mounted in the housing so as to be adjustable axially, thereby varying the clearance between the flange 26 and the bearing surfaces 33, 38 on the second and third rings, and also, due to the non-cylindrical surface 35, between the second ring 36 and the ring 23 carried by the shaft. The ring 36 may have an axial slot 39 to facilitate reduction in the radial clearance between the cylindrical surfaces. The non-cylindrical surface may be frusto-conical (Fig. 1, not shown) or spherical. The centre of the spherical surface is preferably on the axis of the shaft in the plane of the surface 38 of the flange on the ring secured to the shaft.

As shown, a turbojet 6 supplies compressed air to ducts 7a to 7d, 8a to 8d via ducts 7 and 8, the supply being controlled by a valve 18a in a duct 18. Air from the ducts 7a to 7d, 8a to 8d entrains air from outside the machine through forward facing intakes 9a to 9d to supply lift cushions 3a to 3d respectively which ride on the horizontal parts 2a, 2b of the guideway 2, and through forward facing intakes 10a to 10d respectively supplying guide cushions 5a to 5d which face the vertical portion 4 of the guideway 2. At high speed, air surrounding the vehicle enters the intakes 9, 10 with sufficient energy to maintain the cushions, and the valve 18a is closed since compressed air from the turbojet 6 is no longer necessary, and instead the turbojet may be used as auxiliary propulsion means, the compressed air being fed to duct 13.
