Patent GB-1513766-A (GB)
Title: Digital data processing apparatus
IPC: G06F13/00
Filed: 1975-09-25
Abstract: 1513766 I/O systems INTERNATIONAL BUSINESS MACHINES CORP 25 Sept 1975 [30 Dec 1974] 39213/75 Heading G4A In response to an I/O instruction, a port assembly 250 forms and transmits a command (on CBO) and an I/O attachment address (on PORT DBO) together with a first synchronizing signal (CONTROL OUT). An I/O attachment ment 400 decodes the address, responds to the command by providing control signals to I/O devices 425 connected thereto, and generates a response signal (SERVICE IN) to cause the port assembly to drop CONTROL OUT and obtain data from the CPU 15. On receipt of the data, the port assembly transmits the data together with a second synchronizing signal (SERVICE OUT). The responding I/O attachment, having received and accepted the data, drops SERVICE IN and the port assembly reacts to this by dropping SERVICE OUT and notifying the CPU that execution of the I/O instruction is complete. During attempted transfer of data between the CPU and an I/O device via a port assembly, the sequencing of the CPU is halted to temporarily synchronize the CPU and device. The CPU clock is held at a given time state (T3) upon decoding an I/O instruction and remains in that state until an advance signal is received from the port assembly signifying that an I/O attachment has received an address and decoded a command. Sequencing of the CPU is then resumed to effect the data transfer. The port assembly also includes a clock which is started upon the CPU decoding an I/O instruction and which is controlled by responses from the I/O attachments. The CPU includes main and control storage and a plurality of local storage registers (LSR) holding addresses and working and control data, the registers being allocated in groups to different interrupt levels. The I/O instructions specify the type of operation, direction of transfer and the address in main or control storage or the identity of an LSR to act as the data source or destination. Certain I/O instructions produce multi-device commands, e.g. to determine which I/O attachment is requesting an interrupt. The I/O instructions also include a modifier field which is used by the I/O attachments, e.g. in the case of a branch on condition I/O instruction, to specify a condition for the branch to be taken to an address obtained by concatenating the address field of the instruction with the high byte from the LSR for the appropriate interrupt level. Some I/O devices may operate in burst mode, e.g. high transfer rate devices such as fixed discs, and for these devices data transfer is effected in a cycle steal mode when CPU and storage cycles are dedicated to the I/O attachment or device concerned. Operation in cycle steal mode is basically similar to that described above except that no I/O instruction is involved, halting of the processor sequencing being initiated by a cycle steal request from an I/O attachment. Data transfers are checked for correct parity and for reception of responses within a predetermined time-out period which depends on the type of I/O device or attachment addressed.

Title: A reverberation spring
IPC: G10K15/10
Filed: 1970-08-14
Abstract: 1278884 Helical springs AKG AKUSTISCHE U KINO-GERATE GmbH 14 Aug 1970 [19 Aug 1969] 39261/70 Heading F2S [Also in Division H4] A helical spring, used in artificial reverberation systems, has randomly selected turns irregularly deformed within the plane of the original turn. Generally if the turn is deformed as in Fig. 1 the stiffness of the spring will be reduced but its moment of inertia increased whereas deformation as in Fig. 2 will give the opposite effects. By deforming a random selection of turns in the ways shown the periodicity in the frequency spectrum in the range below 200 Hz is eliminated leading to a more natural reverberation. The spring in use is subjected to torsional vibration only and its performance may be further improved by etching the spring surface. In a spring of 2000 turns it was necessary to deform 100 turns to eliminate lowfrequency periodicity.

Title: Improvements in or relating to the production of pigmentary titanium dioxide
IPC: C01G23/07
Filed: 1957-12-19
Abstract: Pigmentary titanium dioxide is prepared by decomposing titanium tetrachloride with an oxygen containing gas in the vapour phase at an elevated temperature in the presence of from 0.01 to 10,000 parts by weight per million of alkali metal, especially potassium, based on the titanium dioxide being produced. Reaction temperatures may be from 800-1400 DEG C., and the preheated oxidizing gas may contain from 10-100% oxygen by volume.  The reaction may be effected in the presence of small amounts of water vapour or aluminium.  The alkali metal may be supplied in the elemental state or preferably as a water soluble inorganic or organic compound such as the nitrate, chloride or sulphate, halide, phosphate, alcoholate, acetate, benzoate, hydroxide or oxide, supplied as an aqueous solution charged to the reaction zone via a separate inlet.  The reaction may be effected in the reactor described in Specification 757,703 where one reactant is discharged as a thin sheeted stream directly into the other reactant in the direction angular to the axis of flow thereof. The oxygen containing gas may be air, oxygen or mixtures thereof; inert gases such as nitrogen or carbon dioxide may be present. Thus for example, preheated vaporized anhydrous titanium tetrachloride containing 1% of aluminium chloride may be charged to a reaction zone maintained at 900-1400 DEG C., together with preheated air containing 50 to 100,000 parts per million of water vapour and 0.1 to 400 parts per million of potassium and in the form of an aqueous soluton of potassium chloride, nitrate or sulphate.  The resulting gaseous suspension at 1150 DEG C. is quenched below 600 DEG C. for example by the method disclosed in Specification 776,419, and the resulting pigment subjected to mild calcination in air at 600 to 900 DEG C. to remove residual chlorine.  The pigment may then be dry milled or disintegrated. Specification 707,560 also is referred to.
