Title: Improvements in or relating to thread winding machines
IPC: B65H67/02
Filed: 1957-02-18
Abstract: 855,958. Winding yarns. REINERS, W. Feb. 18, 1957 [Feb. 17, 1956], No. 5411/57. Class 120(2). An automatic or semi-automatic winding machine having means for automatically replacing each exhausted thread supply cop by a full cop, comprises a magazine, means to deliver full supply cops from said magazine individually to an unwinding station on the machine, and a member automatically operable to grasp the leading end of the thread on a full supply cop and to withdraw a portion of the thread from said cop before the latter is delivered to the unwinding station. In the embodiment shown the winding machine is generally of known construction but has an arm 13 pivoted at 14 and formed at its outer end with a thread grasping member 15 which conveniently is a suction nozzle. In operation, when the absence of thread F between the supply cop on pin 27 and the take up package 3, is detected in usual manner, the guide drum 2 is arrested and then turned in reverse direction. The empty cop is removed from pin 27 which is then rocked into the chain-lines position. At the same time stop arm 31 releases the lowermost cop 25b which slides down the inclined shoot 26a and is engaged by pin 27. Shaft 26 is then rocked to bring the pin 27 and the new supply cop into the unwinding position shown in full lines at 25. During this movement arm 9 is rocked downwardly from the full line position to the chain line position 9a. The arm 13 has already been rccked to the position 13a at which the thread grasping member 15 has withdrawn the thread turns 28 from the nose of the cop which is now in position 25 and the arm 13 has returned to its upper fullline position. The thread end from said cop therefore now extends over guide pin 24 as shown at F2 and consequently as arm 9 returns to its full line position the suction nozzle 11 will entrain thread end F2 and draw it towards the knot-tying device 35 In the meantime the trailing end on package 3 has been found by suction through arm 7 and also taken to the knot-tying device 35 where the tying operation then takes place. Once the foremost cop 25b in the magazine has been released from the stop arm 31 its place is taken by the next following cop, which is then in a position at which the leading turns 28 can be drawn off the cop by the grasping member 15 and held in readiness for the next cop changing operation.

Title: Lateral channel compressor
IPC: F04D23/00
Filed: 1975-02-07
Abstract: 1497343 Side-channel compressors SIEMENS AG 7 Feb 1975 [7 Feb 1974] 5414/75 Heading F1C In a side-channel compressor, the product of the number of impeller vanes and the impeller speed is selected so that the noise frequency is greater than 18 k Hz (so as to be above the limit of audibility of the human ear) and not more than 100 k Hz (to avoid injury to human beings). In the case of a pump running at 3,000 r.p.m, the number of vanes may be increased to 400 or more. Instead, or in addition, the speed may be increased. The vanes, which may be cemented or cast into the hub, may be of resilient material, such as stainless steel or plastics, of a thickness of e.g., 0À2 mm. The reduction of spacing between the vanes consequent upon the increase in their number provides a damping effect which reduces the noise level.

Abstract: 580,005. Voltage measuring. MORRIS, D. G. O., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 5, 1943, No. 5447. [Class 37] [Also in Group XXXV] To derive from a load impedance a control voltage independent of unwanted voltages occuring also in the impedance as for example to obtain an accurate measure of the back e.m.f. of an electric motor, the load impedance is connected in series with an equivalent impedance wherein is produced a voltage equivalent to the unwanted voltage which is then caused to act in opposition to the voltage across the load impedance so as to compensate wholly, partly or in excess, the undesired voltage. Fig. 1 shows a Wheatstone bridge arrangement in which the load impedance and the equivalent impedance R1 (L1) are associated with resistances R3, R4 to provide a potential on conductors 3, 4 in which the unwanted potential, e.g., the resistive or inductive drop in the armature G of a motor, is eliminated. Fig. 2 shows an arrangement to compensate for the voltage occuring due to a change in current in an inductive load, the equivalent impedance including an inductance P having a secondary winding S in circuit with the conductor 4. Fig. 4 shows the application of this arrangement to a four pole machine a wherein the circuit 3, 4 is arranged to balance out the potential drop in the armature brushes. Fig. 3 shows means by which a control quantity dependent in the velocity of an electric motor may be obtained. An amplifier C, such as a vibrating contact device controlling, for example, the voltage applied to conductor 1, 2 in accordance with the difference between the said velocity and a desired velocity defined by a controlling winding w<2> has a winding w<1> connected across auxiliary armature brushes and opposing the winding w<2>, a compensating winding w<3> opposing the winding w<1>, being connected across the equivalent impedance R, L1. Specifications' 566,882 and 577,315, [both in Group XXXVII], are referred to.

Abstract: 1,126,876. Microwave heating. MICROTHERM Ltd. 9 Feb., 1966 [9 Feb., 1965], No. 5573/65. Heading H5H. [Also in Division H1] A microwave source, e.g. a magnetron 32, is matched to waveguides 41, 42 feeding a microwave oven 19 by means of a progressive variation in the impedance of the waveguide 40 in the neighbourhood of the T-junction with the co-axial feeder 38. This may take the form of arcuate inserts disposed against the narrow sides of the waveguide 40 on either side of the antenna 39 whereby the broad dimension of the waveguide is reduced to the diameter of the outer conductor 38 (Figs. 2, 3, not shown). The oven is fed with generally ellipticallypolarized microwave energy by means of mutually-orthogonal oblique slots 43, 44 covered with insulative tape 60. The magnetron 32 is cooled and the oven ventilated by means of a fan 35. Apertures 63 are provided in the wall of housing 10 and further apertures (not shown) in the wall 22 of the oven to allow circulation of air. A closure 26 for the oven comprises a layer 30 of dissipative material.

Title: Conference circuits for use in telecommunications systems
IPC: H04M3/56
Filed: 1973-02-05
Abstract: 1458032 Automatic exchange systems GENERAL ELECTRIC CO Ltd 5 Feb 1974 [5 Feb 1973] 5575/73 Heading H4K A conference circuit for a TDM, PCM system comprises a recirculating shift register into whose stages digital words from the members of the conference are simultaneously gated, and an adding logic connected to all but one of the stages for successively adding different combinations of the words so as in each case to suppress from the sum word which is fed to a conference member the original digital word emanating therefrom. A not shown switching network connects conference members in succession to a 32 channel PCM highway 18 incoming to the circuit and appropriately distributes the 32 channels appearing on an outgoing highway 14 therefrom. Each PCM word consists of a sign bit followed serially by seven logarithmically compressed magnitude bits which are alternately inverted from their true values. These bits are converted to parallel form and the inverted bits are reinverted by converter 22 and then translated into a 12 bit linear code by linearizer 24. In order to facilitate the subsequent addition, the 12 bit codes, which still incorporate a sign bit, are then converted into 211 complement representation so as to make every word positive. (This means that 2<SP>11</SP>=2048 is added to each word.) It is effected by passing a word (including its most-significant sign-indicating bit) unchanged if the sign bit is "1" but inverting each bit (except the sign bit) and adding unity if the sign bit is "0". For example number +1092 (10001000100) converts by adding 2048 to get 3140 (110001000100) whereas number -1092 (010001000100) converts by adding 2048 to get 956 (001110111100). Due to the particular integrated circuits used, the "add unity" stop is not performed in the complementation circuit but in the subsequent adding logic. After conversion, each word is fed into a shift register 28 at the channel multiplex rate used in the system. It is assumed that each conference contains eight or four members so that register 28 is read-out in parallel every eighth or fourth time slot into corresponding stages of an eight or four stage recirculating shift register 32A+32B or 32B alone, respectively. During subsequent slots the words in seven or three stages are read out in parallel to adding logic 38 so as to combine the words from all conference members except one, in each case the one to which the combined word will be transmitted. Each of the adders 40-52 has an additional input for receiving the previously mentioned sign bit so that the "add unity" step can be effected simultaneously with the combining step. Obviously the (15 bit) combined word must be converted back into PCM format before onward transmission (Fig. 4, not shown), provision being made for clipping any combined word which is greater than the maximum value of a 7 bit PCM word (i.e. all "1"s).

A tyre-removing or fitting machine comprises a downwardlyacting pneumatically or hydraulically operated tool-holding piston 15 supported for horizontal adjustment on a stand 1, 6, above a wheel support 30 so that on operation of the piston, the tool 21 carried thereby engages the tyre and pushes it off, or onto, its wheel 31. As shown, an air cylinder 10 in which operates a spring-return piston 11 having a tool-holding piston-rod 14, 15 is supported vertically on a cantilever 6 horizontally adjustable on an upright 1. The piston-rod 16 has a reduced end 17 on which the desired tool may be detachably secured. A pedestal 28 is adjustably spaced from the upright 1 and houses a rotatable drum 29 carrying on its upper face a wheel-supporting spider 30 and a vertically projecting screwthreaded rod 33 having handles 34 and a wheelclamping nut 32. Fig. 3 shows a flat-ended spade-shaped tool 21 for engagement between the tyre bead and the wheel-rim flange, the tool having a manipulating handle 23 and being pivoted to an arm 25 of a piston-rod-engaging socket 26. A retaining spring 40 normally holds the tool, when in use, with its end 22 clear of the wheel-rim flange, operation of the handle 23 causing the tool to pivot to slide the end 22 radially inwardly of the wheel between the rim-flange and the tyre bead. The tool 21 may be formed with a central vertical web to engage the underside of the arm 25 to limit its pivotal movement. For removing rim flanges or locking rings a fork-ended tool 45, Fig. 9, is used, the forked end 46 having rearwardly depending lugs 47 to act on the rim flange or locking ring when the end 46 is fulcrumed appropriately on the rim base or edge. Alternatively, a flat bar bit may be used extending coaxially with the piston-rod and having its end bent to half-round cross-section.

Title: Improvements in or relating to aircraft engine controls
IPC: B61C9/30
Filed: 1943-04-10
Abstract: 570,218. Aircraft engine governors. TAMPIER, R. J. C. April 10, 1943, No. 5780. [Class 135] [Also in Group XXXIII] Simultaneous adjustment of the engine throttle and the constant speed control of an aircraft is effected by a common control member acting through cam mechanism which determines the required relationship of the two adjustments, the constant speed control maintaining the revolution speed of the airscrew constant by varying the pitch, and at a value determined by the setting of this control. In one construction, Figs. 3, 4, a lever 21 connected by linkage 22, 23 to the pilot's control member and to the throttle, respectively, is secured to the spindle 20 of a toothed quadrant 24 geared to a pinion 25 connected by radial teeth to a cam member 3 carried by a spindle 4, the parts being mounted in or on a casing 1 having a cover-plate 2. Adjustment of the constant speed control device is effected by the cam slot which is engaged by a roller 9 on a lever 10 pivoted at 11, the lever being connected through a slidable rod 15 and linkage 18 to the speed control device. Adjustment of the engagement of the quadrant 24 with the pinion 25 with a minimum of backlash is effected by turning an eccentric bushing 19 in which the spindle 20 is mounted, the bushing being fixed in adjusted position by a pin 28 and lock-nut 27. In a modification, the throttle and the constant speed control are both actuated by cams, the two cams being mounted on the spindle 4. The cam or cams may be operated by a cable and pulley, instead of by the lever and quadrant mechanism 21, 24, 25, the pulley being secured to the spindle 4 which, when a spindle cam is used,- as in Figs. 3, 4, carries a further pulley connected to the throttle. The modification in which the two cams are used is suitable for aircraft having means for feathering an airscrew, that is for turning the blades edgewise to the airstream in the event of failure of an engine. The Provisional Specification states that in this case the cam grooves are so designed that the constant speed unit may be actuated for feathering the airscrew after the throttle has been moved to a closed position.
