Abstract: 1,120,616. Packaging from conveyers. FELDMUHLE A.G. 27 Sept., 1965 [25 Sept., 1964], No. 41081/65. Headings B8A and B8C. Material to be packaged is fed directly to open containers 8, Fig. 1, by an endless belt conveyer 1 having an upper horizontal section and a substantially vertical lower section extending downwards towards the mouth of the container, a second substantially vertical endless belt conveyer 10 opposite the lower section of the first conveyer directing any material thrown from the first conveyer by its high speed downwards into the container. Weighing devices 2 deposit weighed amounts of material on the horizontal section. When sticky material is being packaged a frame 13 scrapes the material from the belts 1 and 10. Empty containers 8 are fed into the filling position by a device 9 operating in timed relation with the weighing devices 2, and after filling the device 9 removes the filled containers. Additional belts 14, 15 (Fig. 2, not shown), may be provided to complete an enclosed feeding conduit leading downwards to the container mouth. The belts are displaced relatively to one another in such a way that one edge of each belt faces the surface of an immediately adjacent belt, in order to make it possible to vary the cross-sectional area of the enclosed feeding conduit. The rollers over which the belts run are so mounted as to be pivotable and axially displaceable, so that the form of the conduit may be adjusted to suit the material being packaged. The speed of the conveyer belt 1 is continuously variable. The conveyer belt 1 may consist of two parts, the first part being horizontal, and receiving the material from the weighing devices, and the second part sloping down towards the container mouth. The horizontal section, which is provided with projections extending across its width in order to separate the weighed quantities of material, is driven intermittently, while the inclined section is driven continuously.

Abstract: 934,964. Making beams. J. ROSANES. Nov. 25, 1961, No. 42254/61. Addition to 933,549. Classes 83 (2) and 83 (4). The method of making a hollow box-type beam from sheet metal disclosed in the parent Specification comprises marking on the sheet the positions of the longitudinal edges of the beam, if necessary cutting the sheet along the outer markings, bending the blank successively along the remaining markings until the outer longitudinal edges of the blank abut and connecting the edges by welding, and is modified in that the bends are produced by a bladelike upper die member co-operating with the parallel edges of a groove formed in a lower die member and which in the last bending step is positioned relative to the lower die member so that it lies on a diagonal of the rectangular section at any position along the workpiece. In making a parallel-edged beam the upper die blade is parallel to the edges of the lower die and may be positioned centrally thereof or may be offset. In making a tapered beam the upper die blade is set at an angle to the lower die, in order to satisfy the condition that it lies on a diagonal of the rectangular section. In both cases the offset is calculated by making the ratio x : y (Fig. 7) equal to the ratio a<SP>2</SP> : b<SP>2</SP>, where 7 is the diagonal of the section and the plane of the die-blade and 11 and 12 are the edges of the lower die member.

Title: Improvements in and relating to electric frequency measuring apparatus
Inventor: PENVER GILBERT FRANCIS
IPC: G01R23/00
Filed: 1965-10-07
Abstract: 1,112,448. Digital frequency measurement. ADVANCE ELECTRONICS Ltd. 7 Oct., 1966 [7 Oct., 1965]. No. 42580/65. Heading G4H. In apparatus for measuring the frequency of an electric signal, a further signal is derived having a frequency equal to that of the input divided by n, which signal is applied to a counter 4 having a controllable counting period, and an oscillator 8 is caused to develop an output signal of which the frequency of the nth harmonic differs from the input frequency by a standard frequency (10 mo/s.), the oscillator output being mixed with the further signal to obtain a signal having a frequency equal to the sum or difference of the frequencies of the mixed signals, this signal being applied to control the counting period of the counter to a period n times the standard frequency so that the number counted at the end of each measuring interval represents the frequency of the input signal. The input signal frequency on terminal 1 is applied to a multivibrator 2 which divides the frequency by n. The standard frequency of 10 mc/s., obtained from terminal 7 of the counter, is applied to a phase comparator 21. The oscillator 8 passes its output via a harmonic generator 16 to produce a frequency n times the oscillator frequency. This is mixed at 15 with the input frequency, and the sum frequency is compared at 21 with the standard frequency. The output of the comparator adjusts the oscillator until equality is obtained, the oscillator frequency then being #+ 10 mc/s. divided by n. This signal is then mixed with the output signal of multivibrator 2 (frequency #/n) and the result, after passing through band-pass filter 25, is 10/n mc/s. This is applied to terminal 6 of the counter to set the counting period. In a modification (Fig. 1, not shown), means are provided for first bringing the frequenoy of oscillator 8 to a value from which the phase comparator is capable of adjusting it to the required value. This may be done manually or automatically by a 3-position selector switch providing two preliminary adjustment steps and the frequency measuring operation described.
