Title: Improvements in or relating to rotary counterpressure filling apparatus for liquid containers
IPC: B67C3/06
Filed: 1961-06-27
Abstract: 995,088. Bottling. SEITZ-WERKE G.m.b.H. June 27, 1961 [June 28, 1960], No. 23176/61. Heading B8T. A rotary counterpressure filling apparatus, including a pressurized liquid container 10 with a filler head assembly 12 comprising a liquid filling valve 17 and an air valve 22, to which containers are fed and removed by input and discharge star wheels, has means whereby, after each filled container has been removed from the filler head, an air blast is forced through a pressure and return air pipe 19 for ejecting liquid residues therefrom prior to the filling of a subsequent container. Each empty container is fed upwardly against a cap 30 which forces a star wheel 14 upwardly to open the air valve to effect pressurization, after which the liquid valve is opened and the container filled. The wheel 14 then encounters an abutment and is turned so that the lower end of the rod 23 engages within a groove in the wheel and the liquid and gas valves are closed. The filled container is snifted through a valve 29 and then removed, and the wheel 14 is turned and lowered to the initial position. A cam 25 arranged between the input and discharge star wheels momentarily lifts the wheel 14 to effect a brief opening of the air valve 22 to subject the tube 19 to a short blast of compressed air.

Title: Mechanism for application in a machine for the continuous handling of yarn cops
IPC: B65H54/26
Filed: 1965-06-02
Abstract: 1,114,941. Bobbin supplying. KONINKLIJKE TEXTIELFABRIEKEN NIJVERDAL - TENCATE, N.V. 2 June, 1965 [19 June, 1964], No. 23490/65. Headings D1F and D1J. In a machine winding yarn onto bodies 7  from cops in cop holders 2, a knotting device fhich circulates about the two sides of the machine pulls a carriage 10 (see also Fig. 3 not shown) which supplies full cops to the holders 2. A container (16) (Figs. 4 and 5 not shown) holding columns of horizontal cops is fitted into the top of carriage 10 on rails 18. By manual operation of a plunger which retracts stops the lower row of cops are dropped from the container to lie between an abutment (100) (see Fig. 3 not shown) and hooks (31, 32), Fig. 6 not shown. Cams on a camshaft (34), Fig. 6, rotated by a gear-engaging a rack 55 during the motion of the carriage, displace hooks (31) to allow the ends of cops associated therewith to fall to lower hooks (61), Fig. 6. A further cam on camshaft (34) then displaces hooks (61) to allow each cop to fall between four rotating rods 66, see also Fig. 7 not shown. Due to the rotation of the rods the cop revolves and its free unwinding end is drawn into a suction tube (69), Fig. 7. After a predetermined number of rotations of the shafts 66 a trapdoor (68), Fig. 7, is moved from between the shafts to allow the cop to slide into an empty cop holder 2. The free yarn extending from a slit (72) in suction tube (69) is clamped by means on the winding machine and the excess end is cut off by scissors (75) to be sucked away to a sieve box 94. The clamped end is then knotted to the associated end from yarn body 7. Means are provided to prevent operation as the carriage and knotter pass about the ends of the machine. The knotting device and the carriage are connected by a spring loaded hook (9) (Fig. 3) and if the spring is overextended the drive to the knotting device is switched off.

Title: A method of and device for producing a flow of compressible fluid
Inventor: SARGENT RAYMOND FREDERICK
IPC: G01M9/04
Filed: 1951-10-09
Abstract: 714,169. Wind tunnels. BRISTOL AEROPLANE CO., Ltd. Oct. 8, 1952 [Oct. 9, 1951], No. 23497/51. Class 4. A wind tunnel for producing flow at a Mach number greater than unity comprises a duct, the first part of which is connected to a source of fluid under pressure, and is convergent, and the second part is of substantially constant crosssection and is provided with longitudinal slots adapted to bleed off fluid to an ambient atmosphere of reduced static pressure relatively to that of the stream at entry to the duct. Fig. 3 shows an embodiment on the closed circulation system. The duct 6 conveys high pressure fluid from the compressor 5 to the convergent section 7 terminating in the slotted part 8. The slots are preferably provided uniformly, and their aggregate width amounts to only a small part of the total periphery. If a rectangular duct is used, the slots may be in two opposite sides only. The test object is placed at 17 on any convenient mounting. The slotted duct is supported by radial diaphragms 18, Figs. 3 and 4. The end of the duct 8 may be unslotted to enable the outflow to become uniform after bleeding. The gap between the ducts 8 and 15 is closed, as at 19, and by suitably selecting the size of the gap between them, pressure drop along the slots may be adjusted so that the bleeding is substantially uniform along the length of a slot. The duct may be slightly divergent, to the extent of 1 per cent of its internal diameter. An open circulation system is described, a draught shield being provided for the model, and in this, the slotted duct 8 is made rigid by arches interconnecting the sections between two slots, and one or more circular frames joined to these section externally. It is recommended that the slots should diverge outwards at an angle of not less than 60 degrees, and that the flow of bled fluid should be as free as possible.

Title: Threshold circuit
IPC: H03K19/08
Filed: 1967-05-22
Abstract: 1,116,028. Neuron simulators. RADIO CORPORATION OF AMERICA. 22 May, 1967 [23 Aug., 1966], No. 23633/67. Heading G4G. [Also in Division H3]) A threshold circuit, more particularly for simulating neuron response, comprises a negative feedback amplifier arranged to produce no output for signals below a threshold, a step increase in output when the signals pass through the threshold and an analogue response, e.g. linear, logarithmic, to larger signals. In Fig. 2, D.C. simulated excitatory signals are fed to the emitter of transistor 22 and D.C. simulated inhibitory signals to the emitter of 24. Emitter resistor 40 is smaller than 38 so that the output of a difference amplifier 68 makes an emitter follower 74 conduct only if the sum of the excitatory inputs exceed the inhibitory inputs by a predetermined amount. The output rises stepwise with a small further increase but on reaching a further threshold determined by a diode 92 a negative feedback path becomes effective to reduce the gain and the output thereafter linearly follows an increasing input until the circuit saturates. A diode 80 provides temperature compensation. In Fig. 3 the threshold below which no output appears from an amplifier 102 is determined by a bias applied through resistors 114. Increase of the algebraic sum of the input signals through the threshold produce a sharp rise in output signals until the signal at point 122 exceeds negatively the bias applied by a diode 127 to a diode 124 whereupon the diode 124 becomes non-conducting and thus removes a shortcircuit in the feedback path. The output then follows the input until the feedback potential applied to the emitter 136 renders a transistor 132 conducting to provide such heavy feedback as to prevent further increase, this feedback also serving to maintain the input impedance low Transistor 132 may be replaced by a Zener diode 180. Triodes 148, 150 provide temperature compensation and 156 is a negative feedback output amplifier.

Abstract: 1,112,628. Ultrasonic diagnostic apparatus. SIEMENS - REINIGER - WEBKE A.G. 4 June, 1965 [6 June, 1964; 29 May, 1965], No. 24065/65. Heading H4D. [Also in Division A5] Ultrasonic diagnostic apparatus utilizing the pulse-echo technique comprises a pair of diametrically opposed transmitting-receiving transducers 10, 10<SP>1</SP> (Fig. 3), mounted for rotation about and translation along and at an angle of 45 degrees with respect to the focal line of a cylindrical parabolic reflector 1 by means of a shaft 8. The reflector is carried by a waterfilled housing 6 the front face 28 being sealed by a diaphragm transparent to ultrasonic waves which is inclined such that reflected waves emerge at right angles and in operation is placed in contact with that portion of the patient which is under investigation. The shaft 8 has a circular section over part of its length and a square section over the remainder both sections being slidable in correspondingly shaped bores in a sleeve 37 rotatably mounted via ball bearings 41 and the whole assembly sealed by washers 38, 42. Rotation of the transducer assembly is then effected through a flange 43 carried by the sleeve 37 and frictionally driven via wheels 14<SP>1</SP>, 44 from motor 14. In order to ensure that the movement of the reflected beam across the width of the face 28 occurs with constant velocity the rate of rotation of shaft 8 is varied at a predetermined cyclic rate by giving the intermediate friction member 44 an appropriate shape such as that of Fig. 9 (not shown). The drive from motor 14 may then take the form of Fig. 11 (not shown). Alternatively, the required rotational variation may be produced by the slot-and-pin arrangement of Figs. 12 to 14 (not shown). For producing the translatory motion the shaft 8 is rotatably secured to a plate 15 driven in the directions of the arrows 19 over a range determined by limit reversing switches 21, 22, Fig. 2 (not shown), by a motor 18 and lead screws 16 and to compensate for the effect of such motion on the path length of the ultrasonic beam (see Fig. 4, not shown), which results in a shifting of the echo images reproduced on an image tube, an arrangement (not shown in Fig. 3) utilizing the variation of inductance of an air-gapped coil, secured to the frame 35, by a wedge-shaped metal element carried by plate 15 is utilized as described with reference to Fig. 5 (not shown). Electrical leads from the transducers are taken through a bore in shaft 8 to a two-section commutator 45 (also Figs. 3a, 3b, not shown) with a double brush take-off arrangement 48, 49 to ensure reliability of contact. A common (earth) connection is provided by the metal portions of the apparatus.
