Title: Method of regulation of the tension of a travelling yarn
IPC: B65H59/10
Filed: 1973-05-14
Abstract: 1378135 Regulating yarn tension BLEICHE AG 14 May 1973 [15 May 1972] 2296/73 Headings DID and D1F In a method of maintaining constant the tension in a travelling yarn which is braked by brake members, the yarn is guided in a directed airflow against abutments 9, 10 in such a way that under the effect of the airflow the yarn experiences, between the abutments 9, 10, a deflection which changes in dependence upon the tension, the change in deflection from that corresponding to the desired tension changing the pressure in a pressure head 16 mounted in the airflow, this change in pressure influencing the brake members e.g. discs 29, 30 to restore the tension to the desired value. The travelling yarn 18 has a tension imparted to it by brake members 29 and 30 which are adjustably spring urged together. The yarn then passes through a passage in a block comprising front and back plates 1 and 4. The passage has a base 6 provided by a spacer plate 3 and the block carries abutments 9 and 10 directed towards the base 6 of the passage. An airflow is directed into the passage at the base 6 via a nozzle 11 connected to a hose 13. In the side wall of the passage is situated a nozzle 14 which receives an air pressure by virtue of the air issuing from nozzle 11 impingeing on the yarn 18. The amount of deflection of the yarn determines the air pressure received in nozzle 14. The nozzle 14 is connected to a pressure head 16 via a hose 15. The pressure head 16 comprises a diaphragm 42 which acts on a rod 40 which is in turn connected to a pressure plate 37. The pressure plate 37 is spring urged against the disc 30 which together with the disc 29 forms the yarn brake. Variation in pressure on the diaphragm therefore varies the position of the plate 37 and therefore the pressure between the discs 29 and 30. In an alternative embodiment, the pressure head 16 is provided with electrical contact means on the diaphragm whereby if the tension in the yarn rises to a predetermined value a signal lamp is illuminated. The pressure head may also include contacts which operate when the pressure on the diaphragm falls to indicate a yarn break, and the contacts act on the drive motor of the machine to stop the machine. The front plate 4 of the yarn passage block may be transparent and include a scale 17 indicating the yarn tension.

Title: Lifting gear, particularly lifting jack
IPC: B66F3/02
Filed: 1971-04-19
Abstract: 1298534 Toothed gearing FERD BRASELMANN 19 April 1971 [3 March 1970] 22908/71 Heading F2Q [Also in Division B8] A lifting jack, Fig. 1, comprises a vertical rack 1 with semi-cylindrical grooves 2 at uniform spacing, a carrier element 3, an engagement body 4 rotatable about an axis 5 in the element 3 and a roller 6 rotatable about a shaft 7 in the element 3. The engagement body has three engagement elements 8, 9, 10 each in the form of a segment of a cylinder matching the grooves 2, and arranged at the apices of an equilateral triangle at a spacing equal to the pitch of the grooves 2. The load P is connected to the shaft 7 and produces a reaction Q. These combine to give a line of action C through the axis 5 and the shaft 7. If, as shown, this line C passes above the centre 11 of the lower segment 9 the device is self-locking. The load is raised or lowered by rotation of the body 4 using a lever (not shown), the axis 5 following a series of arcs centred on successive grooves 2. This results in a flapping action as the distance of the axis 5 from the rack 1 varies. There is a minimum of two engagement segments necessary: in general they are arranged at the corners of a regular polygon. Fig. 4 (not shown) illustrates a quadruplex engagement body (28) pressed into engagement with the rack 1 by an opposed flexible rubber roller (25) also serving to support a loadengaging mandrel (24). Fig. 7 shows an embodiment with an engagement body 38 having two engagement elements in the form of pins 41 and rotatable by a lever 44. The pins 41 are pressed into engagement with the rack 1 by a corrugated spring band, carrier element 3 being guided on the rack 1 and supporting the engagement body 38 in slots 37 and the load-engaging mandrel 24 on a rivet 36.

Title: Process for the continuous production of calcium-cyanamide
IPC: C01C3/00
Filed: 1950-09-20
Abstract: Calcium cyanamide is continuously produced by the reaction between elementary nitrogen and calcium carbide by injecting the finely divided carbide as an homogeneous suspension in a gaseous carrier, into a heated reaction chamber so that the carbide is maintained in suspension until the reaction is complete, whilst simultaneously injecting through nozzles separate from that for the suspension, oxygen and preheated nitrogen together with a preheated hydrocarbon gas, the combustion of which is sufficient to raise the temperature of the reaction chamber to at least 1200 DEG C, and finally separating the calcium cyanamide produced. The carrier gas may be nitrogen (preheated to 1000 to 1200 DEG C), air or a hydrocarbon gas. In the preferred embodiment a suspension of carbide in a hydrocarbon gas, such as coke oven gas, is injected into the end of a horizontal cylindrical reaction chamber.  Simultaneously another jet of preheated hydrocarbon gas is introduced by separate nozzles, adjacent to which oxygen nozzles are provided, the amount of oxygen preferably being such that principally carbon monoxide and hydrogen result from the combustion.  The nitrogen nozzles may be distributed about the entry of the carbide, gas and oxygen nozzles.  The reaction temperature may be maintained by recycling hot residual gas and controlled by introducing coal gases or by providing movable cooling surfaces on which the reaction products are deposited.  If a product free from elementary carbon is required, a quantity of oxygen sufficient to convert it to carbon monoxide may be introduced at a point remote from the main reaction zone.

Title: Improvements in and relating to photographic roll-film cameras
IPC: G03B19/04
Filed: 1935-08-20
Abstract: 463,134. Photographic roll - film cameras. CARPENTER, P. Aug. 20, 1935, No. 23359. [Class 98 (i)] A photographic roll-film camera has a film feeding mechanism and a shutter mechanism including a member necessarily movable in effecting an exposure, a disconnectible link between the film feeding mechanism and the shutter control mechanism, and a flexible elongated member having one end thereof connected to the first member and movable therewith under a compressional force and having means associated with the other end thereof for locking the elongated member against movement under a compressional force to lock also the first member against movement. As shown, the take-up spool is wound by the key 8. The camera has an auxiliary wall 9, on the winding shaft 7 are frictional clutches 11, 12 gripping a disc 13. An antinous member 20 is attached at one end of the shutter mechanism and is provided at the other end with a fork 22 having an abutment 26 engaging an abutment 27 on the pivoted indicator blade 25, which forms the disconnectible link and which has a lug 29 engaging the recess 14 in the disc 13. The blade 25 is biassed by a spring 30 to a position in which its lower end is visible through an aperture. A pin 35 on the blade 25 is adapted to engage a notch 36 in the fork 22. The blade 25 is pressed to the right by a spring 37. On winding, the recess 14 engages lug 29, and then disc 13 slips in clutches 11, 12 during completion of winding. When the shutter is operated, the fork 22 is forced up to displace the blade 25 to the right, disengaging lug 29 from recess 14 and permitting spring 30 to pull down blade 25 to indicate exposure. On retraction of the fork 22, pin 35 enters notch 36 and prevents further operation of the shutter prior to winding. On winding, recess 14 engages lug 29 to move blade 25 to the right to permit of shutter operation. In a modification, non- exposure is prevented, the disc being mounted on an auxiliary shaft carrying a toothed wheel engaging perforations in the film or backing paper. A lug on the blade stops the toothed wheel when the appropriate amount of film has been fed. Further feeding is not possible prior to shutter operation. The mechanism permits of time exposure, and means for permitting voluntary double exposure may be provided.

Abstract: 1,102,004. Frequency changing. WESTERN ELECTRIC CO. Inc. 2 June, 1965 [8 June, l964 No. 23462/65. Heading H2F. A frequency multiplying arrangement comprises a 90 degrees hybrid junction 10 in which an input signal of frequency f applied at terminal 1 is divided into two equal signals in quadrature at terminals 3 and 4. Terminal 2 is match-terminated by a resistor 17. Each signal at terminals 3 and 4 passes along a line comprising a filter 13 tuned to frequency f, a non-linear element 15, and a filter 14 tuned to the desired even harmonic frequency 2nf. If n is even, the two outputs are added directly, but if n is odd one output is inverted before the two are added to give the final even harmonic output 2nf. In one embodiment involving waveguide structure (Fig. 2) the 90 degrees hybrid junction 10 is a 3db directional coupler comprising a common narrow wall provided with coupling holes. The input signal is fed to one waveguide, the input end of the other being terminated by a dissipative wedge 28. The waveguides are provided with discontinuities to provide input filters 13, and then with varactor diodes 15. Further waveguides of smaller dimensions provide the output filter and these smaller waveguides are continued, one being twisted through 180 degrees to give the required phase reversal, before being united to a common output section providing a signal 2nf. A further embodiment (Fig. 3, not shown) uses lumped circuits for the filters, the two lines being derived from the ends of a centre-tapped secondary winding of an input transformer. One line is provided with a centre-tapped choke and capacitor to provide the 90 degrees phase shift. The two outputs are coupled together through a further centre-tapped transformer to obtain the single final output. To obtain an odd harmonic output, the output of the even harmonic generator is fed to a further rational fractional generator (Fig. 4, not shown). Fig. 5 (not shown) discloses such an arrangement where the two generators give X2 and 2 respectively, thereby giving an output which is still f but which is isolated from the input. The non-linear elements may be diodes, varactor diodes, gyromagnetic materials, saturable cores, vacuum tubes.
