Title: Improvements in or relating to writing instruments
IPC: B43K7/08
Filed: 1956-12-11
Abstract: 849,629. Reservoir pens. KAHN Inc., D. Dec. 11, 1956 [Dec. 23, 1955], No. 37816/56. Class 146(3). In reservoir pens, particularly of the ball-point type, having an ink reservoir 12 of non-capillary cross-section, leakage of ink through the rear end of the reservoir is prevented by one or more thin flexible discs 21 which rest on the end of the ink column 20 and contact the interior surface of the reservoir. The material of the discs 21, which must be inert with respect to the ink, may comprise polyethylene, polystyrene, nylon, or flexible glass ; and the ink may have a fatty acid base, be quick drying, and have a viscosity of between 16,000 and 20,000 centipoises at 20‹C. Where the reservoir is cylindrical and of inner diameter of 0À16 ins., three discs 21 of polyethylene having each a thickness of 0À0015 ins. and a diameter of 0À16 ins. may be used. The thickness of each disc 21 is increased when the inner diameter of the reservoir is increased, the resiliency of the discs being such that they will follow the end of the ink column as ink is consumed. Reservoirs of oval, rectangular, or other cross-section may be used, and may be made of polyethylene, polystyrene, acrylate and methacrylate resins, brass, or steel : the discs 21 will be shaped correspondingly. As shown, discs 21 are stamped from superposed sheets 31 by a tubular cutter 30 and die 32, the discs being retained within the lower end of the cutter until a plunger 33 is actuated to thrust them into the open rear end of the pen reservoir 12. The plunger 33 has a smaller diameter than the discs, so that the peripheral portions of the discs are unsupported during their insertion in the reservoir, and air can thus escape past the discs during this operation. In a modification, each cut-out disc 21 may be retained on the end of an inserting plunger, as by a vacuum, and then deposited on to the end of the ink column.

Title: Medicated poultry composition
IPC: A23K20/195
Filed: 1964-09-16
Abstract: Oral compositions for administration to poultry via their drinking water comprise a medicament which is one or more of tylosin, 2-amino-5-nitrothiazole, 2-acetylamino-5-introthiazole, and the tetracycline antibiotics, together with sufficient of one or more sulphates of a cation carrying a single positive charge to provide from 0.5 to 50 g. of sulphate ion per gram of medicament. The composition may optionally include a non-toxic carrier. Suitable sulphates are sodium, potassium or ammonium sulphate or bisulphate, trimethyl and dimethyl ammonium sulphate, and sulphuric acid.  In use, the quantity of composition used is usually such as to give a concentration of from 0.1 to 1% by weight of sulphate ion in the drinking water, and the composition may be in the form of a package suitable to provide such a concentration.  The composition is said to induce increased consumption of the medicament by the poultry, since the sulphate causes a greater intake of drinking water.

IPC: G01M1/36
Filed: 1964-09-16
Abstract: 1,125,151. Balancing rotors. NATIONAL RESEARCH DEVELOPMENT CORP. 16 Sept., 1965 [16 Sept., 1964], No. 37917/64. Heading F2U. [Also in Division B3] Balancing apparatus comprises a frame 5 coaxially mounted on a rotating body, e.g. a grinding-wheel, and including balancing masses 1, 2, 3 rotatable on a shaft 6 by pinions 11, 12, 13 rotated by the engagement of star-wheels A, B with fixed stops a, b. The masses have offset holes 21, 22, 23 and the masses 1, 3 together equal mass 2. In one method of balancing, firstly stop b actuates both star-wheels on rotation of frame 5 and the body until a sensor indicates a minimum vibration when the correction angle is correct but the magnitude of the correction is not correct. Now if stop b actuates starwheel B only and stop a rotates starwheel A in the opposite direction, the correction angle remains constant but the correction magnitude varies until the sensor signal is zero at balance. In Fig. 3b (not shown), the mass 2 has an extra gear tooth compared with masses 1, 3 and all three are rotated by a common star-wheel, two stops producing opposite rotations of the star-wheel; in a second method of balancing, using one stop, the correction angle and magnitude both vary until a balance is approached as indicated by a sensor. In the balancing apparatus of Fig. 5b, not shown, similar to that of Fig. 3b, the centre mass is driven in the opposite direction to the other masses through an idler; in Fig. 5a, not shown, a single stop is used with two star-wheels whilst the centre mass has an additional tooth to the others; and in Fig. 5c, not shown, a second stop is introduced into the Fig. 5a arrangement. The Specification includes a mathematical breakdown of the two methods of balancing.

Title: Photoelectric device for detecting the position of a graduation
IPC: G01D5/36
Filed: 1970-08-06
Abstract: 1325457 Photo-electric position determination DR JOHANNES HEIDENHAIN 6 Aug 1970 [6 Aug 1969] 38057/70 Heading G1A In photo-electric apparatus, for measuring the position of a graduation line or mark, in which. an image of the line is directed towards a photo- ' detector and in which there is inter-posed on the radiation path an oscillating wine or shutter or an oscillating minor or plane parallel block associated with a fixed aperture, there is provided either a switch 3 in the photo-detector circuit or a device changing the polarization of the beam, the detector arrangement being responsive to these charges in polarization, the switch or the device being controlled by the movement of the oscillating element, so that the detector output is directed alternately into two separate channels 9, 10 one operative on the pulse sequence occurring during forward movements of the element and the other on the sequence occurring during return movements, the phase relationship between particular components of the same harmonic frequency in the two pulse sequences being determined as an indication of the required position. As shown, changeover of switch 3 is synchronised with the moments when the element changes direction by the output from pulse shaper 7. The device 8 is an adjustable phase displacer to render this synchronisation exact. The switch 3 thus delivers the detector output alternately into identical channels 9, 10 via lines 4 and 5. The particular harmonic frequency of interest e.g. the sixth is determined by filtering out all except this one in filter 34. A reference harmonic waveform is obtained from the oscillations of the element via frequency multipliers 13, 14 and filter 15. This passes via amplitude and phase adjusters 17, 18, for summation with the detector output at 11. The harmonic waveform on line 12 is applied to adjustable phase displacers 21, 22, shapers 23, 24 to produce on lines 25-28 a four-phase output. The signals are inverted by NAND gates 29-32 and used to switch the amplifier 36 output on to one of lines 37-40 in sequence. The anti-phase signals on lines 37, 39 are summed and then integrated at 19, and on lines 39, 40 summed and then integrated at 20. Devices 19, 20 adjust 17, 18 respectively to establish a fixed phase relationship between the harmonic waveform 12 and that harmonic component in the pulses on line 4. The harmonic waveform on line 12 is compared after pulse shaping at 41 with the correspondingly formed harmonic from circuit 10, in phase comparator 42 to give an indication at 43 of the graduation position.
