Title: Plate heat exchangers
IPC: F28D9/00
Filed: 1973-01-10
Abstract: 1376561 Plate heat exchangers MODINE MFG CO 10 Jan 1973 1286/73 Heading F4S A heat exchanger 10 comprises a stack of plates joined to one another at areas 19, 20, 22 and shaped to provide for a first fluid a succession of chambers 26 open at their inner ends and communicating at their outer ends with chambers 23 together constituting a manifold 25, said first fluid flowing outwardly through one group of the chambers 26 to the manifold 25, and then inwardly through a second group of the chambers 26; said plate assembly providing also for a second fluid, a plurality of chambers 21 in heat exchange with the chambers 26. The plates may also be joined together at areas 35 providing a series of chambers 36 constituting a manifold 38. A turbulizer fin 47 comprising a plate with recesses therein (see Figs. 9 and 10) may be provided in the passages 26 and also in the chambers 23. The heat exchanger is intended as an oil cooler in an I.C. engine block 11, the oil to be cooled comprising the first fluid and the engine coolant the second fluid. As shown, the coolant enters the casing 43 of the heat exchanger via an inlet 14, Fig. 1, and flows through the interplate spaces 21 to a casing outlet 15. The engine oil flows from the engine block 11 via a passage 12 to a chamber defined by a gasket 53. From this chamber the oil flows via ports 41 and manifold 38 to an annular chamber 46 formed at one end of the heat exchanger by a cover 43. From the chamber 46 the oil flows via ports 58 either to an oil filter 55, Fig. 1, or to a return header (56, Fig. 2) from whence it returns to the inlet end of a pipe 31 extending centrally through the heat exchanger. From the inlet end of pipe 31 the oil flows via ports 32 to and through the heat exchange chambers 26 and manifold 25, and thence via ports 33 in the pipe 31 to the oil return passage 13 in the engine block 11. On starting-up, when the oil is cold and viscous, sufficient pressure is exerted by the oil on a by-pass valve 60 to open the valve and so by-pass the cooling passages 26 of the heat exchanger until the oil is sufficiently warm. As seen more particularly in Fig. 5, there are three of the manifolds 38 and three of the manifolds 25 in the plate assembly. A further arrangement is described (Figs. 11-14) in which the by-pass path (77) is within the plate assembly.

Filed: 1973-01-10
Abstract: 1418532 X-ray tubes; electrode materials and processing SIEMENS AG 10 Jan 1973 [17 Jan 1972] 1415/73 Heading HID An anode (e.g. rotary type) for an X-ray tube comprises a disc with a zone for electron bombardment and, distinct from that zone, a layer of black material which has been produced by heating a mixture containing titanium dioxide and at least one other refractory oxide. The other refractory oxides may be Al 2 O 3 , CaO, MgO, and ZrO 2 . For example, heating 50% of TiO 2  and 50% Al 2 O 3  produces a black substance with a high coefficient of heat radiation. Additionally the product does not react with common anode materials, e.g. Mo, W, Ta and Nb, below the m.p. of the layer, and adheres to purified and roughened surfaces of same Roughening may be by sandblasting and purification by scouring, ultrasonics, pickling or  heat tratment. Additions to the TiO 2  increase stability for TiO 2  content > 20%. A 68 : 32 mixture of CaO with TiO 2  has m.p. > 2100‹ C. The black layer may be provided by plasma spraying and then heated in vacuo at # 1000‹ C. for 10 mins, the range 500 to 800‹ C. being passed through at < 5‹ C./min. Alternatively, the mixture may be applied, then heated, e.g. an oxide mix applied to the anode by a bonding agent, and heated for at least or about 30 mins. for at least or a about 1600‹ C. Thickness may be a few Á to about 100 Á depending on grain size. In the Figure, anode support disc 10 is of 5% W with 95% Mo, impurities apart. Inclined bombardment zones 12, 13, separately or similtaneously emissive, are on 1À5 mm. layer 14 of W alloy with 10% Rh. Zones 12 and 13 may be downwardly inclined at 10 and 15 degrees respectively. Layer 15 on the lower, peripheral, and inner upper face, is the product of a reaction between 56% Al 2 O 3 -44% TiO 2 . The layer may also be only on the lower face.

Title: Improvements in or relating to receivers for vestigial sideband signals
IPC: H04B1/30
Filed: 1954-01-19
Abstract: 749,038. Automatic phase control systems. WESTERN ELECTRIC CO., Inc. Jan. 19, 1954 [Jan. 21, 1953], No. 1586/54. Class 38 (4). [Also in Group XL (c)] A receiver in a vestigial sideband system, e.g. for television, has a local oscillator for demodulating the incoming signal retroactively controlled in frequency and phase with the carrier or in-phase component of the vestigial sideband signals, thereby eliminating the undesired quadrature component, by a control voltage dependent on the product of the square' of the incoming signal and the square of the local oscillator output after relative shifting in phase by 90 degrees of the squared voltages. In squaring a wave the amplitude of the frequency doubled wave is taken and after relative doubling of any previously introduced phaseshift. By product is meant the D.C. output of a product modulator to which the two equal frequency waves are applied. In Fig. 1 the local oscillator output C is applied through a 45 degree phase-shifting network to a squaring circuit 30, i.e. whose output at twice the oscillator frequency, selected by a filter 32, is C<SP>2</SP>#90 degrees and similarly the amplified output V of the incoming frequency is applied to a squaring circuit 22 with output at twice the incoming frequency selected by a filter 24. The outputs of filters 32, 24 are then applied to a product modulator 26 whose D.C. or lowfrequency output filtered by a low-pass filter 34 is equal to V<SP>2</SP>.C<SP>2</SP> times the cosine of the phase angle between V<SP>2</SP> and C<SP>2</SP>#90 degrees. The letter, which is zero when the incoming signal carrier and local oscillator are in phase and changes in polarity in accordance with the sign of any phase error, being proportional to the sine of twice the phase error, is then retroactively applied to a variable reactance 20 controlling the frequency and phase of the local oscillator 16. The squaring circuit may comprise two pentodes with push-pull input and both anodes connected together and to an anode circuit tuned to twice the applied frequency, the suppressor grids being connected to the control grids to increase the non-linearity. The product modulator may be a ring modulator employing " varistors." In a modification (Fig. 4, not shown) the local oscillator out. puts C relatively shifted in phase by 90 degrees are applied to two product modulators at which the incoming wave V is also applied, so that D.C. or low-frequency outputs V C cos (90 degrees + #) and V C cos # are obtained, # being the error phase of the oscillator, which are then applied to a further product modulator to obtain a zero or low difference frequency of amplitude V<SP>2</SP> C<SP>2</SP> cos (90 degrees  2#) = V<SP>2</SP> C2 sin 2#, as control voltage. In a still further modification the product V<SP>2</SP> C is formed by successive product modulators, then a zero or low-frequency quantity proportional to V<SP>2</SP> C2 cos (90 degrees + #) = V<SP>2</SP> C<SP>2</SP> sin #.

Abstract: 555,297. Coating non-metallic surfaces with metal; alloys. PHILIPS LAMPS, Ltd., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Feb. 6, 1942, No. 1623. [Classes 82 (i) and 82 (ii)] In the coating with metals of non-metallic surfaces, particularly of electrically insulating articles, the surfaces are provided with an intermediate layer of lacquer which is convertible into a hardened final state and which in its plastic and sticky stage is roughened by dusting with powder, preferably metal powder, the metal layer then being applied to the layer of powder e.g. by spraying. The lacquer may be a muffle lacquer such as for example those having a base of urea-aldehyde resin or phenolic-aldehyde resins, and the transformation into the final state may take place before and after metallisation. In an example an article obtained by hot pressing a moulding material consisting wholly or partly of a phenol-aldehyde synthetic resin is provided with a sticky layer of lacquer by means of a solution of a phenol-aldehyde synthetic resin modified by means of china wood oil and colophony. The laquer layer is dusted with zinc powder and the articles muffled for one hour at 170‹C. and the metal coating is produced by spraying or dipping into an alloy containing 50 per cent. by weight of tin, 17 of cadmium and 33 of lead.

Title: Improvements in writing instruments
IPC: B43K24/08
Filed: 1959-01-16
Abstract: 882,447. Reservoir pens. SCRlPTO Inc. Jan. 16, 1959 [June 5, 1958], No. 1646/59. Class 146(3) In a retractable writing instrument having a writing unit 14, the operating mechanism includes a plunger 26, a latch member 28 shaped for displacement within the barrel upon depression of the plunger, and a toggle member 30 disposed between the plunger and the latch member and having the forward and rearward ends thereof pivoted on the latch member and plunger respectively. The plunger 26, toggle 30 and latch member 28 are moulded as a unit from a plastic material and are joined by waisted sections 32, 34 forming flexible couplings. The plunger and latch member are rectangular in cross-section and are slidable in a rectangular bore 20 at the rear end of the barrel, the front end of the latch member abutting the rear end of the unit 14 which is spring-biased into contact therewith. The latch member has laterally extending arms 38, 40 which co-operate with internal shoulders 22, 24 on the barrel and lateral fulcrum points 42, 44. In retracted position of the writing unit, Fig. 1, the arm 40 engages the shoulder 24 and the rearward bias of the writing unit 14 acting on the forward end of the latch member holds the fulcrum point 44 in engagement with one side of the bore 20. When the plunger is depressed from this position the latch member is carried forwards and by reason of the angular transmission of pressure thereto by the toggle 30 tends to rock in an anti-. clockwise direction about the fulcrum point 44 so that when the arm 38 reaches a position laterally adjacent to the shoulder 22 it latches thereunder. When pressure on the plunger is released the parts assume the Fig. 3 position in which the writing unit is projected. A second depression and release of the plunger restores the parts to the Fig. 1 position. The plunger has lateral abutments 36 to limit the distance it can be pressed into the barrel. In a modification the toggle 30 may be a separate piece from the plunger and latch member and may be either secured thereto by pivot pins or engaged for pivoting in recesses in the plunger and latch member. In the latter construction the plunger is spring-biased downwards. Specification 804,903 is referred to.
