Title: Absorption refrigeration apparatus
IPC: F25B15/06
Filed: 1969-01-02
Abstract: 1,200,431. Refrigerating. TRANE CO. 2 Jan., 1969 [5 Jan., 1968], No. 341/69. Heading F4H. An absorption refrigeration system includes a pump assembly 68 having first and second impellers 93, 101 mounted on a common shaft 79, the first impeller serving to draw refrigerant from the evaporator through line 44 and return it thereto through line 48, and the second impeller having first and second passageways 99 and 108 therein. Passageway 99 receives weak absorber solution from conduit 64 via chamber 97 and discharges it through line 104 to the generator, while passageway 108 receives, via conduit 62, a mixture of weak solution from the absorber and strong solution from the generator and forwards the mixture through line 111 to the absorber. Shaft 79 forms part of a motor assembly 47 which receives refrigerant tapped off from line 48 through line 80, the refrigerant serving to cool and lubricate the shaft bearings 82, 90 and to cool the motor before entering the inlet chamber 92 of the first impeller.

Filed: 1974-01-07
Abstract: 1458265 Preparing monomer/polymer syrup MITSUBISHI RAYON CO Ltd 7 Jan 1974 [18 Jan 1973] 00604/74 Heading C3P A methyl methacrylate monomer/polymer mixture is produced by partial polymerization followed by cooling effected at least partially by reducing the pressure continuously or intermittently to below the vapour pressure of the monomer-polymer mixture causing it to boil while controlling the bubbles formed by the boiling. This control is effected by cooling the walls of the vapour space of the reactor and by refluxing the evaporated monomer. Further cooling of the product can be effected by mixing with cooler monomer-polymer mixture and/or by circulating through a heat exchanger. An apparatus is shown having separate heating or cooling jackets for the polymerization mixture and vapour spaces.

Title: Improvements relating to automatic weighing machines
IPC: G01G13/00
Filed: 1922-01-09
Abstract: 195,768. Smith, A., Southall, C., and Partridge, R. B. Jan. 9, 1922. Automatic-feed weighers.- In an automatic weighing machine in which the material is first approximately weighed in the upper of a pair of superposed weigh-pans each carried on its own weigh-beam and the weighing completed in the lower pan, an intermittentlyoperated rotary measuring device is used in conjunction with a continuously-rotating shutter-controlled feeding device for supplying the upper pan, a continuously-rotating shutter-controlled feeding device 'for supplying the lower pan, and electromagnetic and mechanical means for actuating or controlling the feeding devices and the pan deliverydoors. The cycle of operations is followed below from the position in which the upper pan d is full and the weighing in the lower pan f is approaching completion. The dribble flow into the lower pan through the continuously-rotating feeder m continues until the weigh-beam c tilts. This action closes the switch 30, Fig. 1. and thereby causes the excitation of two magnets. One magnet 27, Fig. 2, acts to release the lever 22 and allow the shutter 3, Fig. 6, to be. closed through the action of the spring 24 on the lever 22, link 21 and lever 20. The other magnet acts to withdraw the stop 49, Fig. 8, from the clutch-lever 48, and allow the clutch to come into action, thus setting the shaft 8 in motion. The first result of the rotation of this shaft is that the cam 33, Fig. 1, depresses the lever 40 and opens the doors g of the lower pan, allowing the contents to be discharged. As soon as the lever is released from the pressure of the cam the doors are closed by the spring 45. Immediately afterwards the cam 32 comes into action and opens the doors e of the upper pan in a. similar manner, allowing the contents of that pan to fall into the lower pan. At proper intervals the cams 7 and 23 also come into action causing the shutters 2 and 3, Figs. 5 and 6. of the dribble-feeds to open. Also the disc 51 imparts motion to the measuring device j through the interaction of the pegs 52 and the star-wheel 53. At the end of this motion the clutch is disengaged by the stop 49, and the shaft remains at rest until the next weighing is completed. When the measuring device has delivered the predetermined quantity of material to the upper pan, the dribble-feed k continues the supply until the upper beam b is tilted. The switch 18 is then closed and the magnet 12 releases the lever 6 and allows the shutter 2 to be closed through the action of the spring 9 on the lever 6, link 5 and lever 4. The above cycle of operations is then repeated. Specifications 195,766 and 195,767 are referred to.

Title: Improvements in or relating to clock or like mechanism

Filed: 1931-01-08
Abstract: 370,956. Electric clocks. SMITH, S. J., Hollingsworth Works, Martell Road, London. Jan. 8, 1931, No. 759. [Class 139.] Balances.-In clock or like mechanism of the type in which the hair spring 5, controlling the balance wheel 4 is anchored at its inner end to the balance and at its outer end to an oscillatory member, for example, the stud-ended lever 7, Fig, 1, the pivot 8 of the latter is located eccentrically of the balance wheel pivot to reduce distortion of the spring. The point 8 is taken as the centre of a circle passing through points 9, 10, 11, Fig. 2, formed by the intersection of circles 90, 100, 110 and radial lines 12, 13, 14 corresponding to the positions of the end of the hair spring at its expanded, normal and contracted positions. Alternatively the lever 7 may be attached to a leaf spring anchored at the point 8. The electromagnetic control is similar to that described in Specification 362,518 with the exception that the trip lever 29 is reciprocated by the armature 18 instead of by the stop clicks 23, 24.

Title: Improvements in electrical testing and measuring apparatus and in methods of effecting electrical tests and measurements
IPC: G01R31/02
Filed: 1944-01-17
Abstract: 576,344. Correspondence control systems. MARCONI INSTRUMENTS, Ltd., BARTLEY, W. B., and BROCKELSBY, C. F. Jan. 17, 1944, No. 892. [Class 40 (i)] [Also in Group XXXVI] A conductor to be located varies the screening between two electrical systems. Fig. 1 shows an arrangement for determining the eccentricity of the conductor in an insulated cable. The cable, consisting of the conductor 1 and insulating sheath 2, is guided between metal plates 3, 4. Adjacent parts of conductors 11, 12 run parallel to the conductor 1. The conductor 11 carries an alternating current, a voltmeter being connected to the conductor 12. The conductor 1 and the plates 3, 4 form a screen between the conductors 11, 12, this screen being symmetrical if the conductor 1 is co-axial with the sheath 2. Any eccentricity of the conductor 1 causes unsymmetrical screening and a consequent indication on the voltmeter. In a modification, Fig. 2, a source 10 of alternating E.M.F. is arranged to produce potentials of equal amplitude and opposite phase relative to earth on metal plates 5, 6. A metal plate 7 is connected to earth through an instrument 8. Earthed plates 3, 4, in conjunction with the conductor 1, form an electrostatic screen between the plate 7 and the plates 5, 6, the symmetry of this screen being upset by any eccentricity of the conductor 1. A similar system at right angles to the one shown will show displacements in a direction at right angles to the plates 3, 4. These two indications may be combined on the screen of a cathode-ray oscillograph to indicate the position of the conductor 1. The displacement currents may be separately employed to restore the conductor 1 to co-axiality in succeeding portions of the cable during manufacture. The system may also be used to detect the movement of a metal object moved by a device to indicate liquid level, rate of flow, specific gravity, or pressure, and also to detect the movement of the pointer of an electrical measuring instrument indicating temperature, pH value, conductivity, voltage, current, or frequency. The current due to the unbalance may operate auxiliary gear for the control of any process or quantity, or to restore its earlier condition.
