Filed: 1975-03-13
Abstract: 1472348 Food slicing machine BIZERBAWERKE WILHELM KRAUT KG 13 March 1975 [21 March 1974] 10436/75 Heading A4C A food slicing machine consists of a motor  driven slicing stock feed carriage 18 reciprocably displaceable relative to a circular rotatable knife, and a clamp on the carriage to advance the stock in steps according to the slice thickness, the slices being received on a deposit conveyer 4 drivable in the direction I and transferable by rollers 16 to a transport conveyer 6 drivable in the direction II transverse to the first direction. The deposit conveyer consists of a number of parallel belts 15  driven from a shaft 13 via pulleys 14, the rollers 16 normally being below the upper reins of the belts but movable upwards beyond these reins when it is necessary to transfer slices to the transport conveyer, the peripheral speed of the rollers then equalling the speed of the belt of this conveyer. The numbers of slices in a stack and the number of stacks are settable on a control panel 2 and the machine runs automatically. It is also possible to arrange the slices in a vertical stack and then move them along the conveyers, or during slicing run the deposit conveyer and arrange the slices in overlapping relationship.

Abstract: 645,226. Fluorescent lighting fittings. STUDHOLME, J., and BENJAMIN ELECTRIC, Ltd. April 16, 1948, No. 10633. [Classes 75(iii) and 75(iv)] An electric lighting fitting comprises a channel section body member and a mounting plate carrying a lampholder, the mounting plate being detachably mountable on opposed ledges at the sides of the channel section body and arranged to be retained thereon by spring retaining means inside the body member. As shown a fitting tor a double ended fluorescent lamp comprises a channel member housing a choke 10 and a capacitor 11 and having its edges 4 turned inwardly to form supporting ledges for lampholder mounting plates 3 arranged one at each end of the fitting. Each plate 3 is formed with inturned flanges 6, 6a, Fig. 6, which support a lampholder housing 2 slidably mounted thereon to facilitate making the connection to the lamp. Bowed leaf springs 5, 5a secured to the sides of the channel member 1 at each end thereof engage recesses 7, 7a formed in the sides of each mounting plate to locate it in its correct position. The mounting plate may be assembled in the fitting by entering it diagonally into the channel member 1, resting one side on a ledge 4 (as shown chain-dotted in Fig. 3) and pulling the plate down until the other side rides over the appropriate leaf spring (5a) and rests on the ledge 4a. Alternatively the sides of the plate may be tapered slightly to form a lead as shown in Fig. 6 and the plate entered centrally of the fitting and slid along to the end thereof until the leaf springs engage the recesses 7, 7a. The open bottom of the channel member 1 may be closed by a plain closure plate or by the upper surface of a reflector, supported in either case by wing nuts 15 engaging support rods 14. Where a reflector is used, apertures are provided in its upper surface to pass over the lampholder housings 2.

Abstract: 470,658. Grinding screw-threads &c. BROWN & SONS (HUDDERSFIELD), Ltd., D., and MERRITT, H. E. April 14, 1936, No. 10641. [Class 60] [Also in Group XXII] In a machine for cutting or grinding the threads of worms, screws or the like, the work d is mounted between centres on a slidable table b and the work spindle a is axially aligned with a master screw f running in a nut g carried by a head h, the table and head being connected by a lever i pivoting on a fixed centre c<1> so that the axial movement of the table b produced by rotation of the work spindle may be varied to cut threads of different lead from the same master screw. Instead of rotating the work spindle, the table may for long lead screws be moved axially and relative longitudinal movement of the work and head will then cause rotation of the work spindle. The pivotal connection k of the lever to the head may be on either side of the pivot c<1>. Indexing of the work for multiple-start threads may be effected by rotating the nut in the head during a non- operative part of the cycle.

IPC: B22C5/04
Filed: 1924-04-30
Abstract: 227,338. Bell, W. J. April 30, 1924. Roller-and-breast mills.-A process of disintegrating and mixing moulding sand in which the mass is subjected to rigid disintegrating and mixing means at one side and to flexible disintegrating and mixing means on the opposite side includes the steps of disintegrating the fibre-containing portions, brushing the fibre out by flexible means, carding the fibre from the flexible means by the rigid means, and intimately mixing the fibre with and distributing it throughout the entire mass. In a machine for carrying out the process, the element that carries the flexible disintegrating-means is mounted swingably toward and away from the element that carries the rigid disintegrating-means. As shown, the sand is delivered by a belt conveyer 28, Fig. 1, with buckets to between a rotary element 1 having comparatively rigid disintegrating-projections or stiff metallic fingers 2 and a stationary concave element 3 having comparatively flexible disintegrating-projections or steel bristles 4 forming a steel brush. The element 3 is pivoted at 5 and pressed towards the element 1 by means of a spring 6 adjustable by a screw 7 and nut 20. The treated sand falls on to a screen 11 vibrated by a cam 17, and the metal particles separated by the screen pass over an inclined ledge 13 to an electromagnet 14. The machine is mounted on wheels 29, and the conveyer 28 works in a shoot 25 having a mouth or scoop portion 26. The cam 17 and conveyer 28 are operated by belts from the shaft of the element 1, which is driven by a belt 21 from a motor 8. Fig. 8 shows the element 3 swingably mounted adjacent its upper end at 5<1> on a bolt 35 having nuts 36, 37 on opposite sides of the supporting frame 38. The screw 7<1> with nut 20<1> for adjusting the spring 6<1> is pivoted at 39 to the element 3 adjacent its lower edge.

Abstract: a b -Unsaturated ketones are prepared by reacting diketene with an aliphatic aldehyde containing at least two carbon atoms or an aromatic or araliphatic aldehyde, preferably in equimolecular proportions.  The reactants are refluxed for some hours, if desired in the presence of an inert solvent, and the product fractionated. Before refluxing, the mixture may advantageously be allowed to stand for some time at room temperature.  Examples are given of the interaction of diketene with propionaldehyde, butyraldehyde, 2-ethyl butyraldehyde and benzaldehyde, to give propylidene-acetone, butylidene-acetone, 2-ethylbutylidene-acetone and benzylidene-acetone respectively. Other aldehydes mentioned are valeraldehyde, hexaldehyde, 2-ethylhexaldehyde and heptaldehyde.  The products are useful as solvents and as intermediates for the production of saturated ketones and alcohols.

Title: Ultrasonic transmitter
IPC: H03K3/80
Filed: 1968-03-06
Abstract: 1,204,258. Ultrasonic inspection devices; producing oscillations. NETHERLANDS ORGANISATION FOR APPLIED SCIENTIFIC RESEARCH ON BEHALF OF PUBLIC HEALTH. 6 March, 1968 [7 March, 1967], No. 10889/68. Headings H3B and H4D. An ultrasonic transmitter comprises an array of transducers energized in turn by short bursts of oscillations at ultrasonic frequency. In an embodiment, e.g. for detecting flaws in castings, twenty-one piezoelectric crystals are embedded with intervening insulation in epoxy resin to form a coplanar array. Twenty-one individual circuits as in Fig. 3 drive the different transducers. A burst of oscillations at 1À3 MHz is generated by circuit 4 in which capacitor 27 charges from voltage source A over resistor 29 and discharges in resonant circuit 25, 26, 27, 28 when thyristor 25 is triggered in response to the trailing-edge (detected by circuit 6) of a pulse from monostable, -multivibrator 7 as it switches to the stable state. The multivibrators 7 are triggered into their unstable state simultaneously by a clock signal at input 10, and return to the stable state at different times determined by respective control voltages from circuits 8. These voltages are derived from a common voltage by potentiometers, and the common voltage may take the form of a 32- step staircase waveform. The relative phases of energization of the transducers are thus different for different steps of the staircase, giving 32 different transmitted beam directions for scanning a test object. The staircase waveform is generated by a summing amplifier connected to the stages of a chain of five binary counting stages clocked by the signal at input 10
