Abstract: 899,727. Reservoir pens combined with stapling machines. OFREX Ltd. Sept. 23, 1960 [June 24, 1959], No. 21699/59. Class 146(3) [Also in Group VII] A retractable ball-point pen has a stapling mechanism enclosed and gripped by a removable cap mounted at the rear end of the pen in such a way that retraction of the writing point may be controlled by movement of the stapling mechanism. The ball-point writing unit 3 is slidable in a barrel 1 and is threaded in a member 5 having an inclined rear face 6. The member 5 is slidable but not rotatable in the barrel and is biased rearwards by a spring 9. A member 11<SP>1</SP> is mounted rotatably but axially immovably in the rear end of the barrel and has at its front end two inclined faces 12, 13 against one or the other of which the member 5 is urged by the spring 9. The writing unit extends through and is slidable in a bore in the member 11<SP>1</SP>, rotation of which effects projection and retraction of the writing unit, the projected position, wherein the face 13 abuts against the face 6, being shown in Fig 1 and the retracted position, wherein the faces 12, 6 abut, being shown in Fig. 2. A magazine 16 for staples 20 is releasably secured to the rear end of the member 11 by resiliently mounted projections 34 on the magazine which engage depressions on rearward extensions 31 of the member 11<SP>1</SP>. The writing unit 3 extends into the magazine 16 and has a feeder 21 for the staples slidably mounted thereon and biased rearwards by a spring 22. Leaf springs 17, 18 are mounted outside the magazine 16 and carry respectively a driving blade 17a for the staples and an anvil 19, a tongue 44 cut out of the magazine engaging a slot 43 cut in the blade 17a to guide the latter. A workpiece to be stapled is put between the magazine 16 and the anvil 19 and the leaf springs 17, 18 are then pressed together so that the blade 17a slides down a groove 32 in the magazine and drives a staple 20 into the workpiece. The magazine is refilled with staples by detaching the magazine from the member 11. The feeder 21 is retained on the writing unit by the belled end 36 of the latter. The writing unit may be exchanged, when the magazine has been removed, by unscrewing it from the member 5, the spring 22 and feeder 21 being either renewed with the writing unit or slid off the front end thereof and placed upon the new unit. A cap 41 is a push fit over the part 11 and when in position holds the springs 17, 18 in close contact with the magazine 16. The writing unit may be projected and retracted by rotation of the cap or, when this is removed, by rotation of the stapling mechanism.

Title: Data processing systems
IPC: G06F9/22
Filed: 1974-05-16
Abstract: 1433076 Microprogram controlled processor INTERNATIONAL BUSINESS MACHINES CORP 16 May 1974 [19 July 1973] 21728/74 Heading G4A In a computer in which each of a group of macroinstructions is implemented by control signals derived from a respective sequence of microinstructions, each such sequence including microinstrustions common to all the sequences, a single common microinstruction sequence is stored. The microinstruction(s) in the stored sequence where the microinstructions in the various implementing sequences differ include a field which, when logically combined with a part of the current macroinstruction, produces the required control signals. A number of macroinstructions, e.g. relating to AND, OR, and exclusive-OR operations between the contents of two registers are each implemented by a sequence of microinstructions, all the sequences having common parts, e.g. S1-S3 relating to accessing the macroinstruction, accessing the operands &c., and in general differing only in the actual operation performed. To reduce the amount of microinstruction storage required a single sequence, Fig. 2, only is stored. The microinstructions are accessed in sequence from microprogram store 4 by incrementing an address and loaded in register 5. An additional bit 50 of the first instruction of the sequence causes part of the macroinstruction op-code to be transferred from register 2 to register 7. In the example shown the implementing microinstruction sequences differ only at instruction S4b which has an additional bit 51, which causes the contents of register 7 to be exclusive-ORed with a field 52 in the microinstruction. The field 52 of the microinstruction, 1100, is such that when exclusive-ORed with the 4-bit op-code part of a macroinstruction control signals respective to that macroinstruction are generated and fed to the ALU 6. The macroinstruction op-code may consist of eight bits, the first four defining sixteen groups of operations each with a single stored implementing microinstruction sequence and the second four defining individual operations in a group and being used as above to modify the appropriate stored microinstuction sequence to produce the appropriate control signals.

Abstract: 698,861. Distilling calcium and alkali metals. MINISTER OF SUPPLY. Aug. 23, 1946 [Aug. 24, 1945], No. 21826/45. Class 82(i) A process for the purification of calcium, which contains alkali metal as an impurity, comprises distilling the impure calcium in the presence of an inert gas at an absolute pressure not greater than 2mm. of mercury, condensing substantially pure calcium on a condensing surface of iron or a ferrous alloy and condensing the alkali metal on a separate condensing surface, the two condensing surfaces being maintained at suitable temperatures by separate cooling means. The calcium condensate is then separated mechanically from an iron-containing layer. The apparatus shown comprises stainless steel vessel 1 supported in a fused salt bath 3. The still is connected through pipe 12 and valve 13 with a vacuum pump and a source of inert gas. The calcium condenser is formed by a plate 7 cooled by air introduced through pipe 11 and passing over the radial cooling fins 8. As the calcium deposit increases in thickness the flow of air is increased to maintain the correct temperature on the condensation surface. The impurity vapour, e.g. sodium, passes by the annular space around plate 7 and is condensed on the ring 9 which is cooled by flow of water in coil 10. Additional water cooling coils 14 are provided at the joint between vessel 1 and cover 6 and thermocouple sockets 15 and 16 indicate the temperatures at the calcium-condensing surface and in the still respectively. Specification 270,060, [Class 82(i)], is referred to.

Headings H4F, H4L and H4R. Relates to a subscription television system in which programmes for which a subscriber must pay are transmitted on channels to which a normal commercial receiver will not tune and a subscriber's receiver is provided with an attachment in the form of a frequency converter which translates the signals of a desired programme to a frequency band usable by the receiver. In addition for each programme signal, there is transmitted on a separate carrier a control signal which is employed in the attachment to preset coindemand mechanism to require a predetermined payment. Only when the demand is met or acknowledged is the H.T. supply for the frequency converter completed to allow the programme to be received. Furthermore, there is transmitted for all the subscription programmes a common carrier bearing (by frequency modulation) a " banker " sound signal giving information about the subscription programmes. A characteristic feature of the invention is the provision of yet a further signal in the form of an unmodulated pilot carrier critically spaced in frequency from the control and " banker " carriers. In the receiver attachment this pilot signal functions (a) to beat with the control signal carriers to provide suitable intermediate frequencies, the appropriate one of which is then selected in accordance with the programme it is desired to receive, and (b) to provide a video reference carrier for use with the " barker " carrier so that the two signals, when shifted in frequency appropriately, may be used in the receiver for normal intercarrier sound reception. The Specification gives details of the frequencies to be used in a three-channel subscription system and also includes a detailed circuit diagram of the signal processing portion of the receiver attachment. The subscription signals are received over a cable. The coindemand mechanism and an associated recorder are of known form and not described in detail.
