Abstract: 1,054,003. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 21, 1965 [April 23, 1964], No. 16744/65. Heading H3B. Information is read-out from a magnetic core storage matrix by applying a composite field including an alternating component and a steady unidirectional component and having a peak amplitude insufficient to switch a core irreversibly. In one embodiment (Fig. 3, not shown) a direct current I c  and a high-frequency   current If/2 are supplied to a column selection   lead, and a current Œ If/2 is supplied to a con-   ductor passing in opposite directions through two adjacent rows of cores. A bit of information is thus written into a pair of cores by supplying a total current I c  + If to one core of the pair and a total current I c  to the other core.   For reading, the current I c  + If/2 is supplied to a column selection lead, causing a small reversible flux change in one or other core of a pair which induces an alternating current of phase O or # in a sense conductor passing in opposite directions through the two adjacent rows of cores and connected to a parametric cell. In a second embodiment (Fig. 4) employing one core per bit and a common auxiliary core   T A , currents I c  + If/2 and If/2 are supplied for   writing, while a current. I c  + If/2 is used for reading. If the selected core is in its " O " state during read-out, substantially no current is induced in sense conductor K<SP>1</SP> 1 , whereas a current is induced in conductor K A  since core T A  always remains in its " 1 " state. A signal on line K A  causes parametric cell RK<SP>1</SP> 1  to register a " 0." If core T<SP>1</SP> 1  stores a " 1 " an output is induced in line K<SP>1</SP> 1  in addition to the signal on line K A . The parametric cell has its inputs arranged as a majority circuit so that the signal on line K<SP>1</SP> 1  alone is effective and cell RK<SP>1</SP> 1  registers a " 1."

Abstract: 1,225,691. Flight-path computers. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 31 Jan., 1968 [8 Feb., 1967], No. 5090/68. Heading G4G. In computing apparatus determining deviation between the angular flight-path of an aircraft and a selected descent or blimb path AS (Fig. 1) angled to the horizontal when the aircraft is at required height H and angular distance D from a DME transmitter E algebraically spaced C from the intersection of the selected flight-path with the ground at S, it is shown that H#(C+D)#, so that (Fig. 3, not shown) a resistive potentiometer energized from an A.C. reference source and set in accordance with # energizes a transformer having centre tapped and earthed secondary energizing a resistive potentiometer set algebraically in accordance with C, and a further resistive potentiometer set in accordance with D from a DME receiver. The potentiometer outputs are added to produce signal representing required altitude H which is compared with an actual altitude signal from a pressure altimeter to produce an error indication. When transmitter E is displaced from the vertical plane through AS (Fig. 2) so that EAS = #, the azimuth angle of AS is R m  and the azimuth angle of AE is p; it is shown that H#[D cos (p - R m #)+C<SP>1</SP>]# where C<SP>1</SP> - E<SP>1</SP>S and E<SP>1</SP> is the projection of E on AS. In Fig. 4, potentiometer 2 is set to 0, potentiometer 4 is set algebraically to C<SP>1</SP>, and potentiometer 5 is set to D. The output D# of the latter energizes a resolver 12 whose rotor is angularly positioned to p - R m # by shaft 13 for multiplication by cos 0, and whose output is added at 7 to that of potentiometer 4 to a signal which represents H, for comparison at 10 with an actual altitude signal H R  from 11. Shaft 13 is driven through (p - R m ) by motor 15 together with damping generator 16 and control transformer 14 the outputs of which are combined in amplifier 17 to control the motor; transformer 14, also receiving a signal p - R m  from a differential transmitter 18 adjustable in accordance with R m  and receiving a signal p from transmitter 20 driven from VOR receiver 22. In a modification (Fig. 5, not shown) an adder receives signals p from VOR receiver, R m  from a potentiometer, and control signals from a damping generator and a resistive or inductive potentiometer driven by the shaft, to control the motor driving the same. In a further modification (Fig. 6, not shown), an operational amplifier produces an output u; energizing potentiometers producing signals C<SP>1</SP>u and Du; the latter being multiplied by (p - R m #) in a resolver energized thereby. The resultant signals are combined in the operational amplifier with a signal from an altimeter representing -H, and at balance for substantially null input C<SP>1</SP>u+Du cos(p-R m #)-H=0 so that u represents #<SP>1</SP> of the actual aircraft path, which is compared with a preset signal representing the required path. Other types of computer may be employed, and the difference signal may control an autopilot.

Abstract: 1,228,278. Semi-conductor devices. SIEMENS A.G. 2 May, 1969 [3 May, 1968], No. 22460/69. Heading H1K. A composite semi-conductor arrangement is made by forming one or more recesses, as by etching, in semi-conductor material forming one face of a monocrystalline body, lining each recess with monocrystalline insulating or intrinsic material, filling the lined recesses with monocrystalline semi-conductor material and then forming at least one semi-conductor component in the material in each recess and in the material between the recesses. The original monocrystalline body may be homogeneous and of N-type silicon or comprise a layer of one conductivity type epitaxially grown on a substrate of the opposite type or on an insulating layer on such a substrate. In the latter two cases the recesses extend through the uppermost layer and in all cases the recesses may be filled with material of the same or of the opposite type to that of the layer in which the recesses are formed. In the embodiment the components formed are transistors made by common planar diffusion steps. Where the filling and layer conductivity types are opposed complementary transistors are formed by diffusing the emitters and bases of the respective types of transistor simultaneously and forming the emitters of the latter type in a subsequent diffusion. Suitable materials for lining the recesses are alumina and aluminium silicate deposited from gaseous aluminium aryls and alkyls, and intrinsic silicon carbide.

[Also in Division E1] Debris from the floor of a roadway 4 of a mine is conveyed from the floor and packed into the goaf 10 by a series of simultaneously-acting reciprocating conveyers 20. Each conveyer comprises a guide frame 22 connected to a reciprocable member 24 by a double-acting ram 25, the member 24 pivotally supporting flights 26 whose positions on the member 24 are controlled by rams 28, 29. In operation, the flights first push the debris towards the goaf 10 and are then caused to pivot so as to ride over the debris. The surface area of each flight decreases the further the conveyer is from the roadway 4 and thus a major part of the debris is pushed into the pack area of the goaf. Plates 13, 27 prevent spreading of the debris. As the packing proceeds, the conveyers 20 are continuously advanced with roof supports 6. By reversing the direction of operation of the conveyers 20 and extending the conveyers, the goaf 11 on the other side of the roadway 4 may be packed with debris. In a modification, Fig. 5 (not shown), flights (36) are linked to a chain, rope or rigid rod (37) which, when reciprocated by rams (38, 39) causes pivoting of flights (36). A further modification, Fig. 6, comprises a reciprocable member 50 having a series of triangular-shaped units 52 which, when moving in the conveying direction, present steeply inclined surfaces 60 to the debris which moves further into the goaf 10. In the non-conveying direction the debris slides over less steeply inclined surfaces 58 of the units 52. To pack the debris more densely, a frame 46 on which the units 52 are mounted may also be reciprocable in a direction transverse to the longitudinal direction. The units 52 may be caused to move with a higher velocity in the non-conveying direction. The single conveyer 44 may be replaced by a series of conveyers which operate in step with each other.

Abstract: 1,233,157. Adjustable control pedals. GENERAL MOTORS CORP. 10 July, 1969 [24 July, 1968], No. 34731/69. Heading B7H. An adjustable control pedal assembly in a motor vehicle comprises brake and throttle pedals 26, 62 mounted for pivotal movement on a shaft 22, brake and throttle control members 32, 68 mounted for pivotal movement on the same shaft 22 and connected through links 36, 72 to the brake and throttle mechanism of the vehicle, and respective links 40, 78 connecting the pedals 26, 62 to the members 32, 68, each link 40, 78 being adjustably connected to the associated pedal 26, 62 so that the position of the pedals 26, 62 relative to the links 40, 78 and hence the position of the pedals in the vehicle can be varied and depression of the pedals normally moves the control members 32, 68 in unison with the pedals to operate the brake and throttle mechanism. The links 40, 78 are connected to the pedals by pins 44, 80 which are positioned in slots 48, 82 in the pedals by adjusting members 50, 84 connected to the common crank 54 forming part of a toothed ratchet member 55. A spring-loaded pawl 56 engages the ratchet member 55 to adjustably position the crank 54 and is releasable by means of a lever 92 connected by a flexible cable 88 to a knob on the dashboard of the vehicle. A spring 86 tends to rotate the crank 54 in such a direction that the pedals 26, 62 are urged to their rearmost adjustment when the pawl 56 is released, positioning of the pedals being effected by foot pressure applied thereto against the resistance of the brake and throttle mechanism which is sufficient to reposition the pins 44, 80 in the slots 48, 82. Inadvertent release of the pedals when the vehicle is in operation is prevented by an interlock motor 100 actuated by engine vacuum and arranged to co-operate with the lever 92 to prevent release of the pawl 56 other than when an automatic transmission is in the " Park " condition. In another embodiment, Figs. 5, 6 (not shown), the pedal assembly includes a clutch pedal which is adjusted in unison with the brake and throttle pedals.
