Title: A process and device for applying a self-bonding layer of permanent adhesive to ready-to-use flat floor-covering elements made of materials such as linoleum, synthetic plastics and carpet material
IPC: B05B13/02
Filed: 1964-10-27
Abstract: 1,089,532. Coating apparatus; spray-producers. K. & S. FUSSBODEN - VERSAND G.m.b.H. Oct. 27, 1964 [Nov. 2, 1963], No. 43876/64. Headings B2E, B2F and B2L. Apparatus for applying a self-bonding layer of permanent adhesive on to ready-to-use flat floor covering elements comprises means for heating and means for spraying a partially polymerised self bonding permanent adhesive of tacky consistency including a cross linked inert rubber adhesive on to a face forming the underside of the element, means for heating compressed air to a temperature above that of the temperature of the heated adhesive, conveyor means with side edges forming support margins to support the elements, the spray means being spaced and located above the conveyor and arranged to receive the heated compressed air so that the adhesive is fluidised and dispersed in spray form by the heated air on to the underside of the elements. In the arrangement shown floor tiles 1 which are to receive a coating of adhesive are fed via guides 12 on to conveyor 5 and thus carried beneath spraying apparatus 8. The latter are fed with heated adhesive from tank 7 via heated pipe 23 and. heated compressed air via pipe 37, and are themselves fitted with heating elements to maintain the adhesive at the required temperature (130-160‹F). The compressed air is at between 1.5 and 5 (preferably 2.5) atmospheres (gauge) pressure and is used to eject the adhesive from the spray head and also to compress the normal conical shape of the jet of adhesive into an even curtain of adhesive. This latter is done by two diametrically opposed jets situated immediately beneath the jet outlet from the spray head. The spraying area may be covered above and to the side by a housing 46 (not shown) and a dish 47 filled with water is provided below to catch stray adhesive. The spray guns 14 are actuated pneumatically by compressed air supplied through inlet 17 which effects raising of nozzle needle 21 against spring 20 by piston 19. Adhesive is supplied through inlet 22 and when needle 21 is raised passes by way of inlet chamber 25 into a mixing chamber 26 into which preheated compressed air is also introduced via inlet chamber 28. This compressed air mixes with the adhesive and discharges it through aperture 29. Heated compressed air is also led via two channels 30 to diametrically opposed discharge apertures 31 such that in operation the spray ejected from the nozzle is compressed into an evenly spread spray. One application is for covering floor elements of linoleum, synthetic plastics or carpet material with self-bonding permanent adhesive which is preferably applied to form a pattern of lumps.

Filed: 1968-09-18
Abstract: 1,182,558. Fuses. OLVIS SMELTZEKERINGENFABRIEK N.V. 18 Sept., 1968, No. 44299/68. Heading H2G. A fuse comprises two electrical conductors 4 connected by a fusible pellet 6 which may be of synthetic resin, at least one of the conductors being formed as a winding 5 about a resilient element 3, the connection being broken as a result of a spring action when the pellet melts characterized in that the or each resilient element 3 provides the spring action. Elements 3 are preferably made from electrically insulating material, for example a glass fibre. Heavy currents may cause melting of a conductor 4. In a second embodiment element 3 is made from conducting material and is sprung such that when the connection is broken a further connection between two auxiliary contacts energizes an alarm system (Fig. 2, not shown). In a third embodiment, the fuse is used on a printed circuit board wherein element 3 is bowed between a hole in the circuit board and the printed circuit itself to which winding 5 is attached by means of pellet 6 (Fig. 3, not shown). Two further embodiments are described in which the device is disposed in a cartridge-type case (Figs. 4 and 5, not shown). An alternative construction of the elements 3 is described in which instead of a separate winding 5, elements 3 are etched with a conductor to form a printed winding.

Title: Asynchronous communications bus
IPC: G06F13/38
Filed: 1974-10-16
Abstract: 1487953 Priority assignment TEXAS INSTRUMENTS Inc 16 Oct 1974 [18 Oct 1973] 44831/74 Heading G4A Each of a plurality of master computer devices communicating via a bus with one or more slave devices includes a logic circuit (Fig. 2) for assigning priority among the master devices. The logic circuit includes three bi-stables 51, 52, 53 set for access request, acknowledgment of access grant and access respectively. An access request signal on line 50 from device controller 30 sets bi-stable 51 provided the logic is not already involved in a request. This results in bi-stable 52 being set after a delay determined by network 68 provided signal TLAK on line 43 is high (i.e. if no other master device is acknowledging grant of access) and provided no higher priority device has been granted access. A signal is transmitted via gate 63 to lower priority devices to prevent them gaining access. Bi-stable 52 then resets bi-stable 51 and delivers a low signal TLAK acknowledging that access has been granted. Provided that signal TLAV is high the master device transfers to its access state with bi-stable 53 being set. At the end of an operation the controller 30 generates a signal DLCY so that at the next clock pulse bi-stable 91 is set causing reset of bi-stable 53 (which in turn resets bi-stable 91). During the access state any activity results in a signal TLTM and if no activity occurs for 10 microseconds bi-stable 91 is set via delay 87 to force the logic to its idle state. When a master has access, the transmitted address bits are decoded in a decoder (114, Fig. 6, not shown) at each slave device and in the addressed device data may be written in to a register (111) enabled by a first gate (124) or read out from the register via gates (112) enabled by a second gate (121).  Special function signals.-A signal TLIORES halts and resets all 1/0 devices. A signal TLPFWP indicates that a power shut down sequence is about to occur. A signal TLPRES goes low before any D.C. power voltage begins to fail. A signal TLWAIT resolves conflicts in computer/computer communications.

Filed: 1972-09-28
Abstract: 1360583 Thread cutting machines A BECHLER 28 Sept 1972 [30 Sept 1971] 44852/72 Heading B3T An automatic thread cutting machine comprises a bed 1 with a headstock 2 carrying a rotatable work spindle 3, a longitudinal slide 9 carrying a transverse slide 10 on which is mounted an indexable tool carrier 11 which carries a plurality of cutting tools including thread cutting tool assemblies 14 which effect radial and parallel movement of the tool 15 relative to the axis of indexing of the carrier 11. The operating cycle of the machine is controlled by cams and cam operated switches from the main motor 2 by way of belts and gearing 44-53 and shafts 28 and 18, and the indexing of the tool carrier is controlled by motor 61 by way of belt 63 and pulleys 64, 65 and a notched cam plate 69 and lever 66a. In operation the workpiece is rotated with the spindle 2 by mounting in a chuck 4 and the motor 61 is actuated to index the appropriate tool, e.g. a thread cutting tool 15 into an operative position, e.g. as shown in Fig. 1. The thread cutting tool assembly 14 comprises a housing 33 rigidly secured to the tool carrier 11 a slide 34 displaceable in the housing by way of the drum cam 38 and a cross slide 35 supported by the slide 34 and which carries the cutting tool 15, a further cam 39 rotatable with the cam drum 34 with shaft 37 controls the infeed and retraction of the slide 35 and the tool 15 after a thread cutting pass along a workpiece carried on the chuck. The movement of the cutting tool 15 during thread cutting operation is effected solely by the motion of the slides 34 and 35 of the assembly 14 the main slides 9 and 10 of the machine being stationary. The operation of the slides 34 and 35 is effected from the headstock gearing and by a Cardan shaft 54 and bevel gears 55, 56 and 59, 40, which drive the shaft 37 to rotate the cams 38 and 39. The machining operations performed by other cutting tools mounted on the tool carrier are controlled by the operation of the main slides 9 and 10.

IPC: H02M1/088
Filed: 1967-10-04
Abstract: 1,196,015. Converting. ALLMANNA SVENSKA ELEKTRISKA A.B. 4 Oct., 1967 [11 Oct., 1966], No. 45191/67. Heading H2F. [Also in Division H1] In a static converter arrangement having a number of series connected thyristors arranged in a substantially vertically disposed helical arrangement, each storey (i.e. 360 degree turn of the helix arrangement) of which includes at least four thyristors B1-B4 with their associated cooling elements A1-A4, voltage dividers C1-C4 and controls D1-D4 for turning on and off the thristors, the thyristors are uniformly distributed around each storey with the cooling element A1-A4 of each thyristor directed towards the central axis of the helical arrangement and the voltage dividers and controls for the thyristors are grouped in pairs with a pair of voltage dividers C1, C2; C3, C4 or a pair of controls Dl, D4; D2, D3 located in the space between adjacent thyristors. The cooling elements A1-A4 are supported by the walls of a channel G through which coolant is passed.

Title: Data handling arrangement
IPC: G06F3/02
Filed: 1974-10-23
Abstract: 1485855 Selective signalling GENERAL ELECTRIC CO 23 Oct 1974 [26 Dec 1973] 45840/74 Heading G4H In data handling apparatus, a data-present signal from any of a plurality of data sources, in conjunction with a system timing signal, produces a transfer-initiating impulse at a time within the timing signal period which is correlated to the identity of the source, the firstoccurring transfer-initiating impulse causing the corresponding source to be connected to a data sink, a signal being generated to suppress, during transfer of data, disturbance by other data sources. Fig. 1 shows four input units 51, 52, 53 (all at bottom left), 54 (dashed box), for a printer 25, having a priority order defined by the fact that timing pulses 36 from the printer 25 are delayed 1, 2, 3, 4 clock times respectively before application to ANDs 32 in the units 51, 52, 53, 54. The clock time referred to is the period of clocks 39, 49 from printer 25, being one tenth the period of the timing pulses 36. Unit 51 may be a CRT or computer, unit 52 a tape reader, and unit 53 an answer-back option source. Unit 54 is a keyboard. In the keyboard unit, actuation of a key at 1 is encoded 5 and passed by gates 6 to an input register 7. If one and only one key is actuated, detectors 11, 12 cease to enable gates 6 via OR 13 and enable AND 19 to pass the next timing pulse 36 from printer 25 to gate at 8 register 7 to an intermediate register 15, and after a delay of one timing pulse 36 at 21 to produce a pulse from OR 13 which resets register 7 via AND 28 and opens gates 6 for the next keyed character. Presence of a character in register 15 is detected 16 to produce a pulse from AND 32 at the priority time (see above) to printer 25 which removes the strobe enable signal 31 to disable AND 32 in each unit 51, 52, 53, 54 to prevent premature further requests. The pulse from AND 32 also sets a flip-flop 48 so that the next timing pulse 36 transfers 37 (with addition of start, stop and parity bits) the output of intermediate register 15 (after possible alteration at 35) into a shift register 40 which converts from parallel to serial. The printer 25 provides pulses 42 to sample 43 the data bits into a bit buffer 44 to feed the printer 25. Rollover problems in the keyboard unit are avoided since the period of timing pulses 36 is less than the interval between successive key actuations during rollover typing.

Title: Production of 5'-inosinic acid by fermentation
IPC: C12P19/32
Filed: 1963-11-20
Abstract: 51-Inosinic acid is prepared by culturing an adenine-requiring auxotrophic mutant of Brevibacterium ammoniagenes in an aqueous nutrient medium containing adenine, with the resulting accumulation of 51-inosinic acid in the medium and cells.  Any adenine-requiring auxotroph of the said micro-organism is suitable, whether requiring other growth factors (e.g. biotin, xanthine) or not.  Mutants employed in the process have the following A.T.C.C. numbers: 15187, 15188, 15189 and 15190.  Conventional media containing a carbon source, a nitrogen source and minerals may be employed, with adenine added per se, or as an adenine-containing source (e.g. R.N.A., fish meal, yeast extract, corn steep liquor), under aerobic conditions with suitable pH control (e.g. CaCO3, urea, NH4OH, NaOH). Inosinic acid and, if desired, hypoxanthine which occurs as a byproduct, may be recovered by conventional means, such as ion exchange procedures, and the inosinic acid may be crystalline as the sodium salt. Examples are given for the process, using the above mutant strains of Brevibacterium ammoniagenes, cultural and reinoculated in shaken broth cultures.

Title: A land mine
IPC: F42C7/00
Filed: 1962-12-06
Abstract: 982,049. Land mines. H. KLOSTERMANN, [trading as R. RINKER]. Dec. 6, 1962 [Sept. 22, 1962], No. 46193/62. Heading F3A. A land mine in which the fuze comprises a spring-stressed firing pin 17 held away from a primer 16 by a retaining member 7 is provided with a clackwork actuated locking member 4b engaging a notch 7b on the member 7 to render the mine safe. Moreover, when the mine is armed, a load acting on a head 7c of the member 7 prevents operation of the mine. The mine housing 1 is of plastics material divided by a web into compartments for housing explosive charges 26, 27 and the fuze components, the clockwork 4, which has a winding shaft 4a, being placed eccentrically. A membrane 8, e.g. rubber, seals the mine cover 3. To set the mine, the clockwork 4 is wound by means of a handle 25 and a weight, of at least 1 kg. and up to a maximum of 100 kg., is placed on a pressureplate 9, which bears against the head 7c through membrane 8 and so frees the member 4b. When the clockwork has run down, the member 4b is withdrawn from the member 7. If the weight is then lifted, the member 7 is pushed aside by the striker, which then fires the primer 16. This in turn fires a detonator 19, which ignites a relay 13 and so detonates the charges 26, 27. In a modification (not shown) the member 7 and membrane 8 are replaced by a ram displaceable axially of the mine by a spring to free the striker when the locking member 4b is withdrawn by the clockwork mechanism.
