Abstract: 1520835 Weighing apparatus HUNTING ELECTROCONTROLS Ltd G HANNAM and R M DAVIES 18 April 1977 [27 April 1976]  17082/76 Heading G1W Weighing apparatus includes means for supporting an article 21 above a weighing surface 12, for directing cooling air at the article, for lowering the article on to the surface, and for removing it after weighing. The air passes from a chamber 13 through perforations on the weighing platform 12 except during weighing. The articles are removed on a conveyer 22. In a system for blow moulding glass containers glass gobs 7 are cut by a shearing device 5 from glass 6 flowing from a crucible past a restrictor 3 whose position is adjusted manually by handle 28 or electrically via motor 26 to vary the flow and hence the weight of the gobs.

Abstract: 146,139. Charbonneau, L. A. Feb. 20, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Pulp, prepanation of.-Flax or other raw material is prepared for use for spinning purposes or as paper pulp by being subjected firstly to a series of mechanical operations to remove the straw &c. and part of the dried glutinous matter, and then to break the material to give it a definite length and secondly to a series of chemical operations to complete the removal of the glutinous matters, to bleach the fibre and to " hydrophilise " it. The raw material is passed through a breaker a, Fig. 1, a scutcher b, and is then fed by a feed regulator c<1> to a double carding machine c. After being soaked in water it is then passed through a series of vats d - - k, Fig. 2, by endless conveyers. Each vat is provided with stirrers, an overflow arrangement, an inlet for liquid, and a pair of pressing-rollers d<1> - - k<1> at the exit end.

Title: Improvements in and relating to filters
IPC: B01D46/00
Filed: 1934-06-09
Abstract: 439,684. Filtering liquids and gases. FAIRLEEDE ENGINEERING, Ltd., and FRY, H. D., 123, Cannon Street, London. June 9, 1934, No. 17169. [Class 46] [See also Group XXVIII] An unbacked filtering material not sufficiently rigid to support itself is mounted in such a manner as to have the capacity of shearing movement. An endless strip 5 of felt is stretched in a zigzag fashion over two series of springs 6, 6<1>, having hooks at their ends which pass round rings 8, 9, 8<1>, 9<1>. The hooks bear against the ends of outer and inner cylinders 1, 2, which are free to move axially relatively to one another. A cover 14 is connected to the cylinder 1 and a central cone 3 to the cylinder 2. Fluid filtering upward through the medium 5 passes away downwardly through the cone 3. Suction of the fluid on the cap 14 causes axial movement of the cylinder 1 and a consequent shearing deformation of the medium 5 which aids in detaching the retained solid matter from the medium. To prevent leakage at the edges of the strip 5 the walls of the cylinders 1, 2 may be made to bulge towards the filtering space as by the provision of superposed packing strips 10 of different width. Spacing-members 13 keep adjacent folds of the material 5 apart. Electric or mechanical means may be provided for causing the oscillatory movement of the cylinder 1. A cylinder or collar attached to the cap 14 may project into the cone 3. As shown in Fig. 4, the filter 16 is arranged in a box to which the fluid is admitted through a tube 19 and from which it is discharged, after passing upward through the filter, through a tube 23 with a throttle valve 24. A crankarm 25, which may be weighted to balance the weight of matter collecting on the filtering- medium, connects the spindle of the valve 24 with a cylinder 29 fixed to a cone 22 connected to the inner cylinder 21 of the filter. A bellows member 27 seals the joint between the tubes 19, 22. This form of the apparatus is stated to be applicable for separating sand from air in a sand blast. For large apparatus suitable for air-conditioning plant a filtering- material 5 may be arranged between flat walls.

[Also in Group XL (b)] The invention relates to the control apparatus of copy-milling machines of Specifications, 561,171, [Group XL], 583,520, wherein a rotating shutter interrupts a beam of light passing by the edge of a template to energize a photo-electric cell, the resulting pulses from the photo-cell being fed through a mechanical or electrical switching mechanism operated in synchronism with the rotating shutter to a driving means controlling the relative movement of the cutting tool and the workpiece in each of the four component directions of a co-ordinate system. The improvement of the invention comprises the addition of an amplifier followed by a generator which translates the variable pulses from the photo-cell into pulses of fixed duration and transmitting these constant duration pulses to the switching arrangement. As shown, Fig. 2, a tracing head comprising a light source 10, a rotating shutter 12 and photo-cell 14, is mounted for horizontal movement relative to a template 16, the output of the cell 14 being fed through an amplifier 28 and constant duration pulse generator 30 to quadrature phase speed amplifiers 18, 20, 22, 24 operating a North-South motor 38 and East-West motor 46, driving the tracing head, the amplifiers 18-24 being switched in synchronism with the rotating shutter 12, so that the position of the photo-electric pulses in the cycle determine the direction of travel of a work piece relative to the cutting head. The shutter 12 may have a simple pin-hole, or a series of pin-holes on varying radii, or an arcuate slot, or an eccentric semi-circular opening.

In Fig. 1 electromagnetically actuated hammers 5 are actuated in turn, respective circuits 6a detecting contact between the hammers and the band 1 to open a NAND gate (17) which is closed when the respective eddy current sensor 6b detects the arrival of the resulting transverse wave. A tension profile may be displayed on a cathode ray oscilloscope, Fig. 5 (not shown) or clockpulses may be counted while the NAND gate is open in respective counters. The rollers 2, 3 may be adjusted automatically to obtain uniform tension. In modifications, the transverse waves may be produced by pneumatic jets, Fig. 4 (not shown), with upstream and downstream eddy current sensors, or by hydraulic jets (of lubricating oil), Fig. 6 (not shown), with pressure sensors (39) for opening the NAND gate. Transverse waves produced by the rolling mill itself or by a take-up reel may be sensed by two lines of sensors or by a single line of sensors, the time differences being measured.
