Title: Improvements in interconnecting medium
IPC: H01R24/58
Filed: 1965-03-12
Abstract: 1,098,396. Printed circuits. GENERAL ELECTRIC CO. March 12, 1965 [March 30, 1964], No. 10677/65. Heading H1R. In a printed circuit board for interconnecting electronic components of, e.g. a high-speed digital computer, first and second sets of conductors are located within first and second surfaces of a support member so that the conductors of the first set cross the conductors of the second set, and predetermined conductors of each set form signal conductors and are electrically shielded by the remaining conductors of the associated set, the said remaining conductors being interconnected at their cross-over points. As shown, Fig. 3, an insulating board, e.g. of epoxy paper, is provided on its major surfaces with two mutually perpendicular sets of alternately deep and shallow parallel metallized grooves. The shallow grooves 3, 7 are of a depth less than half the thickness of the board and the conductors therein form signal conductors, interconnections being made where required by metallized holes 11. The deeper grooves 2, 6 are of a depth at least half the thickness of the board, so that they intersect at cross-over points 15, the conductors therein being interconnected to form a shielding network for the signal conductors, which network may be connected to earth or some other reference potential. External connection to the signal conductors is by means of metallized holes 14 which form sockets for the reception of connector pins, component leads &c. The grooves may be formed in the board by etching, machining, or moulding, and, like holes 11 and 14, are formed before the metallizing step, which may constitute electroplating the whole board with Cu &c., the plating being subsequently removed from the faces of the board by grinding or sanding; alternatively, the grooves may be entirely filled with a conductive material. Holes 13, which divide signal conductors where desired, are drilled after the metallizing step. In modifications, the deep grooves, or all the grooves, may be less deep than half the board thickness, interconnection between grooves being effected by drilling.

Title: Improvements in methods of and apparatus for packing goods in pre-formed flimsy containers
IPC: B65B7/04
Filed: 1940-06-24
Abstract: 542,148. Packeting. BEE BEE BISCUITS, Ltd., and BUXBAUM, E. K. June 24, 1940. No. 10815. [Class 94 (i)] Relates to the packeting of fragile articles such as biscuits, and granular and comminuted materials, in preformed open containers made of flimsy material, such as thin sheet cellulose acetate, metal foil, or waxed paper. According to the invention, the containers are moved stepby-step through the machine, and the mouths of the containers are closed by the successive action of a movable folder, which operates while the container is at rest, and a number of passive folders which act while the containers are moving between successive periods of rest. The containers are supported by cups 4, Figs. 1 and 4, secured to an endless conveyer chain 1 which is moved intermittently by a Geneva wheel 5. The cups are detachably secured by central screws 10, Fig. 4, to plates 11 attached to the chain, so that they can be replaced by others of a different size. The movement of the conveyer brings each cup to rest in eight stations, I ... VIII. At station I, a cup receives an open container from a mechanism A of the kind described in Specification 542,244. At station II, a label is deposited in the bottom of the empty container by mechanism of the kind described in Specification 543.463, [Group XVI]. At stations III, IV and V a biscuit or the like is deposited in the container by mechanism of the kind described in Specification 542,228. At station VI, the leading side of the container meets and is indented by a stationary folder 29. while the rear side is folded down on top of the biscuits by an oscillating folder 15. During this operation, the sides of the containers are engaged and supported by suction heads 31 which are connected by pipes 33 to a vacuum main, a camoperated valve 35 controlling the application of suction. During the movement of the cup from station VI to station VII, the folder 29 folds the leading side of the container down on to the depressed rear side, and at station VII these folded portions are heat-sealed to one another by an electrically-heated die 43 which is lowered on to the folded material. The upstanding ears are folded down by converging rods 49 during the movement of the container from station VII to station VIII, and in the latter position the folded ears are heated sealed by an electricallyheated die 51. A disc of insulating material may be inserted after the filling operation if the goods will not stand the heat of the sealing dies. The completed package drops out of the cup on to a conveyer belt 58 and travels over other belts 59, 59a to a delivery point. In order to hold the empty containers in the cups, each screw 10, Fig. 6, is drilled with an axial channel 63, and the plate 11 travels over and in contact with a suction box 60 so that suction is applied to hold the empty container in place. Instead of heat-sealing the containers as they are folded, an adhesive label may be applied to the folded container.

Title: Improvements in or relating to the cultivation of micro-organisms
Inventor: NINH KY CHARLES
IPC: C12P19/02

Abstract: 1,208,572. Recovering yeast &c. BRITISH PETROLEUM CO. Ltd. Feb. 8, 1968 [March 8, 1967], No. 10827/67. Heading C6F. A material consisting of, or containing, a major proportion by weight of a micro-organism and a minor proportion of a hydrocarbon is heated under conditions such that the cell walls of the cells of the micro-organism undergo change but such that after the heat treatment a major proportion of the cells remain intact cells i.e. cells which retain their cytoplasm within their cell walls. Examples and comparative experiments demonstrate that the phosphorus and ash contents of the yeast product are lower when the heat treatment is included. According to an example, the product stream from the cultivation of Candida tropicalis on a gas oil in the presence of an aqueous nutrient medium and a free oxygen-containing gas, was decanted to remove aqueous phase. Fresh water was added to the yeast cream in order to reconstitute the original mixture, a small proportion of a lauric alcohol oxyethylenated and sulphated detergent was added to the mixture and stirred, and the emulsion produced was centrifuged to give a gas oil phase, an aqueous phase and a yeast paste. The yeast paste, diluted with water, was heat treated at a temperature of 100‹ C. for one hour in a vessel equipped with a propeller and then centrifuged hot. The yeast slurry thus obtained was dried to a cream in a drum drier, and the cream (containing 50% by weight of yeast) was twice extracted with a solvent mixture consisting of equal parts by weight of n-hexane and isopropanol firstly at 80‹ C. for 30 minutes and then at 50‹ C. for 30 minutes. After filtration of the solvent loaded with some yeast impurities, the remaining product was treated with isopropanol at 50‹ C. for 10 minutes. Finally, the yeast product was dried with superheated steam and the moisture, lipid, phosphorus, ash and nitrogen contents of the yeast were determined. The proportion of intact cells in the material after the heat treatment was 95%. In further examples the heat treatment consisted of: (a) injecting steam at 50 psig to hold the temperature of the yeast at 100‹ C. for 30 minutes; (b) washing for 2 hours with hot water to maintain the yeast at 90‹ C.; or (c) heating at 70-80‹ C. for 30 minutes.

Abstract: 844,591. Transistor bistable circuits. MULLARD Ltd. April 1, 1959, No. 11052/59. Class 40(6). A bistable-state circuit comprises two reciprocally coupled transistors T1, T2 and a semiconductor diode D connected in its forwardlyconducting direction in the path constituted by the cross-connection from the base of one transistor T1 to the collector of the other transistor T2 together with the collector circuit of said other transistor, whereby on the gradual application of the collector biasing voltage V cc  the circuit always assumes initially a state in which the other transistor T2 is conducting owing to the relatively large resistance exhibited by the diode for small values of applied voltage. Instead of being connected as shown the diode may be connected in one of the crossed base-collector couplings. Triggering may be effected by application of a pulse to cause the transistor T3 to bottom momentarily, the output being taken from transistor T4. A further output transistor T5. symmetrically arranged with respect to transistor T4, may be provided; this ensures that the two transistors are substantially equally loaded and also permits two oppositely-phased outputs to be taken.

Title: Electrical indicating device
IPC: G06F7/50
Filed: 1950-01-02
Abstract: 675,060. Detecting a potential difference. NATIONAL CASH REGISTER CO. Jan. 2, 1950 [Jan. 15, 1949], No. 11126/50. Divided out of 675,032, [Group XIX]. Class 37. [Also in Groups XIX and XXXVIII] An electrical device for indicating data represented by one or the other of two possible electric potentials on each of a plurality of electric contacts, includes two brushes for scanning the contacts and means for driving the brushes, the brushes and contacts being so arranged that the potentials of two adjacent contacts are sensed at the same time by the two brushes, and means controlled jointly by the potentials of the two brushes for stopping the brushes when one brush is on a contact having one of the two possible potentials and the other brush is on a contact having the other potential. The device is applied to the electronic counter described in Specification 675,032, [Group XIX], to which reference is made, in which a count is represented by the highest of a ring of ten digitrepresenting valves to be conducting. Associated with each valve of the ring is a pair of contacts, e.g. 77, 78, so connected to the cathode circuit of the valve that, when the valve conducts, their potential is raised. The contacts are scanned by a stepping rotary switch arm carrying brushes 85, 86 which at any moment respectively engage the contact 77 of one valve and the contact 78 of the next higher valve. The brushes 85, 86 are respectively connected to the grids of a double triode 92 so that, when they engage the contacts of the highest conducting valve of the ring and the lowest non- conducting valve, the potential of the anode 94 of the valve 92 will decrease due to the corresponding half of the valve becoming conducting. A current will thus flow between the two anodes of the valve 92 via a rectifier 100 and a solenoid 101. The solenoid opens contacts 102 in the circuit of the stepping drive solenoid 104 so that the switch arm ceases to rotate. A dial carried by the switch arm shaft indicates the value registered. Specification 593,682, [Group XIX], also is referred to.

Title: Improvements in the reduction of oxidic iron ores
Inventor: REED THOMAS FRANK
IPC: C21B13/00
Filed: 1957-04-08
Abstract: A method of continuously reducing oxidic iron ore comprises continuously feeding finely divided iron ore to a primary reactor and then to a secondary reactor, introducing ascending currents of reducing gas to the secondary reactor air of off-gas from the secondary reactor to the primary reactor to maintain fluidized beds in both reactors, the reducing gas being hydrogen or carbon monoxide or a mixture thereof, maintaining a temperature of between 1100 DEG F. and the sticking temperature of the products in both beds, and controlling the conditions to produce FeO in the primary reactor and Fe in the secondary reactor.  The fresh reducing gas should have the minimum amount of oxidized products present and the ratios CO2/CO and H2O/H2 are preferably controlled in the off-gas from the secondary reactor to be near the equilibrium value for the reduction of FeO to Fe. The heat necessary may be obtained by heating the one to 1600 DEG F. to 1800 DEG F. and the reducing gas to 1500 DEG F. to 1700 DEG F.
