Title: Propane treatment of petroleum wax
IPC: C10G73/06
Filed: 1955-07-28
Abstract: Petroleum wax is purified by dissolving in propane, passing the solution to a settling zone, maintained at 150-200 DEG  F., for a time sufficient to precipitate colour-producing resinous material, and separating the wax therefrom.  The wax may be dissolved in 3-5 times its volume of propane.  The solution may be maintained in the settling zone for 15-30 minutes.  After separation of the resinous material, the propane solution may be cooled to precipitate wax, which may then be deoiled by steam stripping; the deoiled wax may be mixed with a solvent such as petroleum naphtha or normal heptane and filtered through a clay such as Attapulgus clay to separate resins. Finally the naphtha may be separated from the wax by stripping.  In the example, the treatment of petrolatum with liquid propane is described.

Abstract: 1520239 Virtual-to-real address translation INTERNATIONAL BUSINESS MACHINES CORP 24 May 1977 [21 June 1976] 21898/77 Heading G4A A system of the type, Specification 1,438,039, using a directory look-aside table DLAT to store recently used translations, avoids the use of translations from DLAT which were derived from a set of segment and page tables which is not valid for the currently requested address by appending an identifier ID to each DLAT entry, which ID must match that associated with the requested virtual address for the corresponding translation to be read out. In such a system, whenever DLAT entries become invalid the DLAT must be purged by resetting the invalid bits 100 for those entriesa somewhat lengthy process. The present invention saves time by storing with each DLAT entry a count field W supplied by a purge instruction counter 84 at the time the entry was written into DLAT and making read-out of any DLAT entry conditional on its W field matching the current contents of counter 84. In this way the DLAT only has to be purged once for each full count of counter 84.

Title: Improvements in or relating to Helicopter Rotors
Inventor: CHEESEMAN IAN CLIFFORD
IPC: B64C27/32
Filed: 1967-05-12
Abstract: 1,188,391. Helicopter rotors. MINISTER OF TECHNOLOGY. 10 May, 1968 [12 May, 1967], No. 22070/67. Heading B7W. [Also in Division F2] A helicopter rotor comprises at least one variable incidence blade 6a carried by a rotatable head member 2 mounted on a non-rotating structure 1, two apertures (23 and 24) (Fig. 5, not shown) extending along the span of the blade from which air is discharged tangentially over the surface of the blade to induce lift, means being provided for leading air to the head member and thence to the blade, and non- rotating control means for varying the air stream into the head member 2. As piston 12 operating in a cylinder 11 is attached by rods 13 and 14 to the pin 15 on the blade root, fluid supplied above or below the piston by way of the concentric tubes 80 and 85 causes displacement of the piston and thus variation in blade incidence. The means for leading air to the blades, and the non-rotating control means are described in Specification 1,073,418, with the modification that the total air flow may be varied by slide valves 57 which are connected via a control box 61 to an hydraulic system operating the piston 12, allowing the mass air flow to be varied with the angle of incidence of the blade. At a particular blade incidence cyclic and control lift variations are applied by varying the momenta of the air streams discharged from the apertures (23), (24), the blade incidence angle remaining unchanged until a new phase of operation is required. In another embodiment an alternative rotor hub is used (Fig. 13, not shown), a rotating drive shaft (101) carries sockets (102), supporting the blade root members (103) and a sleeve (104), connected to the blade root members by a link rod (105) surrounds the drive shaft and is movable axially. Movement of the sleeve causes rotation of the blade root members and hence the blade. The rotor blades are similar to those previously described in Specification 1,073,418, and are connected to an air distributer (110), a transfer part (111) and to the outlets of an annular array of segmental parts.

Abstract: 1,204,780. Logic circuits. RCA CORPORATION. 10 May, 1968 [7 June, 1967]; No. 22269/68. Heading H3T. A bi-stable circuit, Fig. 2, employing, for example, majority logic, has a plurality of threshold gates M1, M2, M3, M4, two of which, M1, M2, each receive three binary external inputs-a bias signal O, a trigger signal T, and control signal J or K, and the circuit operates thus: if O, T are the same then the output Z of the circuit is unchanged by J and K, but if O and T are opposite, the output Z changes in response to J and K. More particularly, the gates all having majority outputs m and minority outputs m (Fig. 1, not shown), when T becomes 1 with the bias signals remaining 0, then if J, K are 1, 0, respectively, Z unconditionally becomes 1; if J, K are 0, 1 then Z unconditionally becomes 0; if J, K are 1, 1 then Z changes from its existing value unconditionally; and if J, K are 0, 0 then Z is unchanged from its existing value (i.e. J-K type operation). In a modification (Fig. 3, not shown) selective admission of data via a further gate (M8) is controlled by a signal G which is applied to the gate (M8) together with a reference signal 0, and the data signal, and which is also applied in place of bias signal 0 to one (M5) of the input gates. If G is 0, then operation is as in Fig. 2; if G is 1, then the output Z depends upon the previous value of Z as well as upon the current values of T, J and K.

Title: Matrix storage device
IPC: H04J3/04
Filed: 1958-07-11
Abstract: 857,302. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. July 11, 1958 [Aug. 3, 1957], No. 22391/58. Class 40 (9). [Also in Group XIX] In a ferrite matrix storage device comprising storage elements which are accessible via row and column wires to which half-counting and half-reading pulses are applied, and a common reading wire which provides output signals of the same sign irrespective of the particular storage element being read, half-reading pulses with opposite polarity are fed to two row or column wires to compensate for noise pulses. The core matrix shown has separate row wires 1-4, and column wires a-d which are fed in pairs from the output windings of transformer T1, T2. Thus, e.g., if the core at the junction of wires 2 and c is selected for read-out by applying negative half-reading pulses to these two wires, a positive half-reading pulse also is applied to wire d whereby the noise pulses generated in the columns of cores associated with wires c and d cancel each other out. Further compensation is provided by an additional line of cores Ka-Kd and by a transformer coupling T between the row wire circuits and the reading wire 5. The application of the invention to a ferro-electric type of store is mentioned.
