Title: Improvements in evaporators or degasifiers for continuously-acting absorption refrigerating machines
IPC: F25B33/00
Filed: 1931-03-12
Abstract: 373,688. Refrigerating. LEHMANN, B., 16, Schillingstrasse, Reinickendorf, Berlin. March 12, 1931, No. 7680. Convention date, April 7, 1930. [Class 29.] Absorption machines and systems.-The evaporator or, in the case where refrigerant vapour is evolved from strong solution, the degasifier of an absorption machine consists of a vessel having a liquid reception compartment in its base connected by small bore tubes surrounded by brine &c. to be cooled to an upper vapour compartment to which solvent liquid or weak solution is carried by the refrigerant vapour. The bore of the tubes may be made sufficiently small to prevent by capillary action the return of the weak liquid to the lower compartment or, alternatively, the upper ends of the tubes may extend above the liquid outlet of the upper compartment. In an apparatus including a generator 3, main and auxiliary evaporators 13, 8, main and auxiliary degasifiers 67, 68, an absorber 48 and a reabsorber 51, the refrigerant vapour flows from the generator 3 to the condenser 6 and thence through the pipe 7 to the auxiliary evaporator 8 in which it is precooled, and from which it passes through the pipe 9 and control valve 10 to a vessel 19 communicating with both the liquid and vapour compartments of the main evaporator 13 having brine inlet and outlet pipes 17, 18. From the vapour compartment of the main evaporator the vapour passes through the pipe 60 to the reabsorber 51, while the liquid flows into the vessel 21 and thence to the lower compartment of the auxiliary evaporator 8, the upper vapour compartment of which is also connected to the reabsorber and to a vessel 24 from which the liquid flows through a pipe 27 having a control valve 28 to another brine cooler 29 and a vessel 30 from which it passes to the liquid compartment of the main degasifier 67. The vessel 30 is also connected by a pipe 45 to the vapour compartment of the auxiliary degasifier 68 which is connected to the main degasifier in the same manner as the auxiliary evaporator is connected to the main evaporator. The vapour compartment of the auxiliary degasifier communicates with a vessel 44 having a vapour outlet to the absorber 48 and a weak liquid outlet to the pump 46 which forces the cooled weak liquid through the pipe 50 to the reabsorber 51, the strong liquid from which flows through a pipe 53 forming a heatexchanger with the pipes 50, 54 and a control valve 55 to the vessel 30. Brine to be cooled enters the auxiliary degasifier at 56 and passes through the pipe 57 to the main degasifier and thence to the cooler 29 from which it is discharged at 59. Liquid is circulated between the generator and the absorber through a heatexchanger 2 by a pump 1. Specification 16835/13, [Class 29, Cooling &c.], is referred to.

Abstract: 422,667. Typewriters. ROYAL TYPEWRITER CO., Inc., 2, Park Avenue, New York, U.S.A.-(Assignees of Myers, L. C. ; 20, Wilson Place, Freeport, New York, U.S.A.) March 12, 1934, No. 7793. Convention date, March 24, 1933. [Class 100 (iv)] Line-spacing mechanism.-The mechanism comprises a manually operable spring-controlled lever and a pivotally mounted or like yieldable spring-urged stop adapted to engage the lever and limit its return movement, the return spring for the lever being connected also to the stop so as to urge the stop against the lever to produce a noise-reducing stop. The bell-crank line-spacing lever D is mounted by a pivot 12 on the upper side of a shelf 7 projecting from the end plate 5 of the platencarriage, and is provided with an arm 9 operating by means of a link 10 and arm 10<1>, a line-spacing pawl 11. A stop-lever E is pivoted at 11<1> to the under side of the shelf 7 and is provided with a raised stop-member 16. An arm 18 is fast to the line-spacing lever spindle 12 on the under side of the shelf, and is drawn towards an arm 17 of the stop-lever E by a spring 21. When the lever D is in an inactive position, shown in dotted lines, the arm 13 of the lever E rests against the plate 5. Actuation of the lever D tensions the spring 21 through the arm 18, which returns the lever D when it is released. The impact of the arm 9 against the stop member 16 rocks the lever E slightly to the dotted line position, but the levers are then returned to their inactive positions by the spring 21, the noise and shock of the return movement being thereby diminished.

Title: Improvements in memory devices utilising magnetic thin films
IPC: G11C11/14
Filed: 1968-02-19
Abstract: 1,218,984. Magnetic storage apparatus. SPERRY RAND CORP. 19 Feb., 1968 [20 Feb., 1967], No. 7912/68. Heading H3B. [Also in Division H1] A magnetic memory element comprises two thin films superimposed on each other and sandwiching a bit drive line therebetween so as to form a closed magnetic flux path around the drive line and has the ends of the thin film members coupled by high permeability material yokes forming a closed double flux path in the form of a figure 8. In a first embodiment, Fig. 1, the memory element 10 has two E- shaped ferromagnetic film layers 24, 25 deposited on a glass substrate 16 and having their easy axes parallel to 22. Three thin films 30, 31, 32 are then vapour deposited over layers 24, 25 after which a bit line 44 is deposited but insulated from film 30 on to connector strips 38, 39. After applying further insulation, three further thin films 50, 51, 52 are superimposed on films 30, 31, 32. The storage layers 30, 50 may be formed by successive depositions of four insulated layers of Ni-Fe of 1000  thickness and the non-memory layers may be formed by successive depositions of ten layers of Ni-Fe of 1000  thickness separated by insulation. In operation to store information in the element 10, current is passed through coupled word lines 20, 21 passing through apertures 18, 19 in the glass substrate 16 resulting in a circumferential magnetic field being set up, Fig. 7 (not shown), comprising two closed flux loops meeting at the central area defined by films 30, 50. The magnetic layers 24, 25, 30, 31, 32, 50, 51, 52 form a path of low reluctance. The word current establishes a field which tends to turn the magnetization of layers 30, 50 into substantial alignment with the hard axis 23. A current is then passed through bit line 44 to establish a drive field parallel with the easy axis 22 in one or the other direction representing a " 1 " or " 0 " which field persists after the termination of the word pulse to rotate the magnetization of the films 30, 50 into alignment with the easy axis. In order to read out non-destructively information from the memory element, a current is applied to word lines 20, 21 to generate a field which rotates the magnetization of the films 30, 50 out of alignment with the easy axis 22, the polarity of the induced output signal in the bit-sense line 44 being indicative of the bit stored. In the embodiment of Fig. 8 (not shown), the word lines are of circular crosssection and pass through circular apertures in the substrate, and the E-shaped side members 24, 25 of Fig. 1 are replaced by rectangular strips.

Title: Improvements in or relating to means for coupling shafts or other rotatable bodies
IPC: F16D3/30
Filed: 1920-03-17
Abstract: 165,162. Merz & McLellan, and Twinberrow, J. D. March 17, 1920. Universal joints.-In universal coupling- means for connecting one shaft to another or to its equivalent, such as an annular gear-wheel, of the type in which the driving and driven elements are connected to an intermediate member a.t the ends of two mutually perpendicular co-planar axes, each element is allowed, relatively to the intermediate member, (1) to oscillate, in the plane containing its shaft and its axis of connection, about a point at or near the centre of the intermediate member, (2) to pivot about its axis of connection, and (3) to slide along his axis. Endlong sliding may also be permitted. The driven gear-wheel of an electric railway vehicle may be mounted on its axle in this way in order to accommodate the relative movements between the axle and vehicle frame. As shown in Fig. 2, an annular gear-wheel 23 driven by pinions 30 is riveted to the flange 21 of a. hollow shaft 11, and engages by a pair of flat-faced projections 14 an intermediate member 12 of I-section ring-form, which engages a similar pair 13 carried by the axle 10. The projections 13, 14 slide freely in all directions between bearing-blocks 28, which can turn between pads 27 about radial axes, but are prevented by ribs 29 from radial movement. The pads 27 may turn, when the arms 13, 14 and blocks 28 are worn, on the cylindrical seatings 26 of pockets 24 in the ring 12, which are closed by covers 25 accessible through apertures in the flange 21. In the modification shown in Fig. 5, the intermediate member takes the form of two T-section rings 31 bolted together and enclosing the pockets between them. The gear-wheel 23 is borne by three equidistant twin-rollers 32 running on tracks adjacent to the teeth and carried by the vehicle or other frame 34. This type of mounting, or the construction of the intermediate member, can be applied to the first form described. As shown in Fig. 7, the member 12, in the form of a star-shaped plate, is mounted within a driving-wheel 35 and has thickened portions in which are slots 112 to receive the sliding-members 113, 114, carried respectively by the wheel-disc and by arms 14 of the gear-wheel 23. The slots have central seatings for pads 27 which carry bearing-blocks 28 as before. The wheel-casing 360 has covered apertures 37 opposite the universal connections.

Title: Improvements in the reception of continuous wave wireless signals
IPC: H03J7/14
Filed: 1921-03-16
Abstract: 181,799. Round, H. J. March 16, 1921. Heterodyne receiving systems; group-frequency tuning arrangements; thermionic valves, arrangements of.-In receiving apparatus for continuous waves in which note tuning is employed, any variation in the frequency of the received waves causes a corresponding variation either in the tuning of the note-frequency circuit or in the frequency of the local oscillations. In an example, note-frequency oscillations in the circuit A, Fig. 1, act on the circuit B which is tuned to the note frequency and coupled to the receiver K, and on the circuits C, D, which are tuned respectively to frequencies above and below the note frequency and so arranged that normally they do not affect the resistance of the valve I. Variations in the frequency in the circuit A unbalance the effects of the circuits C, D, on the valve I and cause an alteration in its resistance, and consequently a variation in the mutual inductance between the coil J and the circuit B, the tuning of which is consequently varied. In another example, two heterodynes L and M, Fig. 2, are used such that L normally produces a note-frequency N', the circuits C, D being tuned to frequencies N<1>+r and N<1>-r. Variation in the frequency of the received wave unbalances the effects of the circuits C, D on the valve I and consequently varies the current flowing round the coil P and consequently the magnetization of its core and the inductance of the coil Q wound thereon. The heterodyne frequency is thus altered.
