Title: Automatic programming for detent type tv tuner
Inventor: MAYLE LOUIS FERDINAND
IPC: H03G3/20
Filed: 1969-10-28
Abstract: 1,243,924. Radio receiving arrangements. MAGNAVOX CO. 28 Oct., 1969, No. 52762/69. Heading H3Q. In a television receiver with a turret tuner located by a detent mechanism, the turret is continuously rotated by means of a motor until a signal is received. In one embodiment, VHF tuner 17 is rotated by motor 13 via gear-box 16 when either " start " button 29 is pressed, closing switch 28, or a command is received by remote control signal receiver 36 from remote control unit 34. Rotation of tuner 17 continues, contacts 18 being held closed by axial movement of the motor armature, until both (1) contacts 24 are opened by cam-follower 22, co-operating with cam 21 driven by the gear-box, and (2) contacts 31 are opened by the reception of a signal. Contacts 31 include the armature of a relay whose coil 37 is in the collector circuit of a transistor 42, energized from the A.C. supply over resistors 39, 58, diode 41 and capacitors 56, 57. In the absence of a signal transistor 42 is biased non-conductive; on the interception of a signal, sync. pulses from source 53 energize a tuned circuit 44, 48 coupled to the base of transistor 42 by winding 43, causing it to become conductive and operate relay 37. In a second embodiment (Fig. 3, not shown) the camoperated switch is replaced by a detent mechanism and the bias to render the transistor conductive is derived from the receiver A.G.C. circuits. In embodiment, movement of the motor armature also opens a second set of contacts to mute the receiver. In a further embodiment (Fig. 4, not shown), the transistor is biased from a winding coupled to the last I.F. circuit of the receiver, and a switch coupled to the detent mechanism discharges the A.G.C. capacitor in rotation of the turret between stations, so that a weak station is not lost due to hangover of the A.G.C.: further contacts connect a neon lamp into circuit in the detent positions of the tuner. The arrangement may be made more sensitive by replacing the transistor with a Darlington pair, (Fig. 5, not shown), and instead of the switch contacts discharging the A.G.C. capacitor, a diode may be used in the A.G.C. circuit to give a slow-rise, quick-fall action (Fig. 6, not shown).

Filed: 1976-12-30
Abstract: 1525610 Silicon nitride DEFENCE SECRETARY OF STATE FOR 30 Dec 1976 [30 Dec 1975] 53217/75 Heading C1A Reaction-bonded silicon nitride material is subjected to impregnation to introduce iron oxide therein. Suitably, the material is exposed to an iron-containing compound to deposit the compound in the silicon nitride material, followed by heating to decompose the deposited compound and form the iron oxide. Alternatively exposure to the iron-containing compound may be carried out at a sufficiently elevated temperature to ensure deposition of iron in the reaction-bonded silicon nitride in the form of iron oxide. Impregnation may be effected by placing the silicon nitride in a solution of the compound, suitably a solution of an iron salt in its own water of crystallization, or by vacuum impregnation using a solution of an ironcontaining compound. Colloidal iron compounds e.g. colloidal hydrated or hydroxylated oxides, organic compounds of iron, e.g. the acetate, oxalate or oleate, may be used, readily decomposable oxygen-containing iron salts being preferred, especially ferric nitrate hexahydrate or nonahydrate. The treated silicon nitride may be dried at about 150‹ C and the iron oxide formed by heating to 850‹ C.

Title: Method of using a digital computer for determing the start and finish times for activities contained within a precedence network
IPC: G06Q10/00
Filed: 1972-11-23
Abstract: 1375917 Digital computers: precedence networks BURROUGHS CORP 23 Nov 1972 [6 Dec 1971] 54131/72 Heading G4A A digital computer is used for determining the start and finish times for each activity contained in a precedence network, e.g. using PERT and CPM for building an aircraft carrier or planning a business merger.  The precedence network comprises activities (i.e. operation steps) each having a time duration associated therewith and vectors, each vector representing the relationship between two activities (e.g. the first activity must finish before the second one starts or one starts after the other has started). Each vector can carry a time indication, e.g. the second activity starts a predetermined time after the previous activity has ended.  All the activities and their vectors are loaded into a general purpose computer (Fig. 7, not shown) including a core memory, a disc memory, an 1/0 multiplexer, a card reader and a printer. Then, for each activity, a list of predecessor and successor activities (Figs. 5 and 6, not shown) is created in step 26 by reading each vector in turn. Then all the activities without predecessors are loaded into the top of a stack memory, the validity of the topmost activity is checked and the start and finish times for it are calculated in step 36 (described in detail with reference to Fig. 3, not shown). Then any constraints on the current activity's successors are calculated (step 46), these are loaded into the bottom of the stack, the current activity is removed from the top of the stack (step 32) and the next activity evaluated in the same way. For each activity it is calculated how many times it returns to the top of the stack and this is compared with the number of its predecessor activities. If the former is larger, an error has occurred and the loop is terminated (step 42); if the former is smaller, step 32 is entered and the current activity is removed from the top of the stack. If they are equal this would have been detected in step 38 and step 42 would have been executed. This is repeated until step 46 has been calculated for all the activities.
