Abstract: 1296548 Testing two port networks STATNI VYZKUMNY USTAV PRO STAVBU STROJU 11 Nov 1969 [11 Nov 1968] 55147/69 Heading G1U In order to determine the transmission properties of a network 2, Fig. 4, under test, a signal A1 is applied to the network, its output signal A2 is amplitude modulated 5 on to a carrier S1, and the output signal M from the modulator is applied to a phase sensitive detector 8 receiving a reference signal S2 having a frequency equal to that of the upper sideband from the modulator 5 to produce an output signal V1 having a average D. C. level proportional to the product of the amplitude of the fundamental frequency emitted by the network and the cosine of the phase shift produced in the fundamental by the network. In the preferred embodiment shown the signal A1 applied to the network is produced by mixing 11 the outputs of two generators G, g and using the difference frequency. Also a further phase sensitive detector 15 is provided in quadrature with the first to produce a second output signal V2 proportional to the sine of the phase shift introduced by the network 2 under test. One method of operating the arrangement shown is to adjust the phase of the signal S1 from the generator G until the D.C. component of the signal V2 is zero. The phase shift in generator G necessary to achieve this is then equal to the phase shift produced in the fundamental by the network under test, and the D. C. component of the output signal V1 is then directly proportional to the amplitude of the fundamental transmitted by the network.

Abstract: 1324399 Moulding pipe grooves INDUSTRIELE ONDERNEMING WAVIN NV 28 Aug 1970 41591/70 Heading B5A A thermoplastics pipe is given an internally grooved end by heat softening the end and pressing it over a core comprising a mandrel 1, an annular groove forming member 2 and a sleeve 3. Subsequently the sleeve is removed and the, now oversized, end of the pipe pressed or heat shrunk into contact with the newly exposed surfaces 2a and 1b of the forming member and mandrel respectively. Finally the mandrel is withdrawn and the forming member collapsed to enable its withdrawal from the pipe end. In one embodiment, see Fig. 2, the forming member comprises a series of abutting links, for example 11-14, hinged together at 30 and an unhinged link 10, the links being biased into contact by a spring 9 located in aligned passages 8 in the links. During its location upon the mandrel, the links of the forming member are all aligned as shown, and to effect removal of the member from the flared pipe end the link 10, which is outwardly tapering, is moved radially inwardly, surfaces 10a, 10b of link 10 sliding over surfaces 11a and 12a of links 11 and 12 respectively. This causes the links 11 and 12 to move toward each other thus effecting radial collapse of the member. In a second embodiment, not shown, the groove forming member consists of a series of arcuate links hinged to each other, the adjacent faces of one pair of links being unhinged. In use the links whose faces are unhinged are pivoted inwardly to cause collapse of the member.

Abstract: 1331425 Containers for pressurized beverages METAL BOX CO Ltd 12 Oct 1970 [7 Aug 1969 25 Feb 1970] 39535/69 and 9073/70 Headings B8C and B8D [Also in Division B1] A container such as a can comprises a first chamber 15 or 77 for holding a liquid such as beer under pressure, a second chamber 14 or 76 for holding a gas such as CO 2  or CO 2 /N 2  under pressure, and a dividing wall 12 or 71 having at least one through slit 16 or 78 which is normally held closed by the resiliency of the material but which opens due to the pressure difference thereacross when the first chamber 15 or 77 is opened. The second chamber is situated at the can bottom below the beer so that when the can is opened gas passes through the slit(s) into the beer to assist in the formation of the beer head. The slit may be formed in the membrane 17A of a rubber or plastics valve bung 17 inserted in a chamber-dividing wall 12 (40, Fig. 4) or may comprise an integral part such as the disc 73 or portion 72 of a frusto-conical dividing wall 71 made of a resilient thermoplastics material such as polypropylene or polyethylene. The gas may be introduced through an inlet comprising a hole 19 or crescent-shaped slit (50, Fig. 5) to pass between an internal inlet-covering resilient patch 20 and the can base 11. Alternatively, the gas may be introduced through a passage(s) which is located between a plug 81 and the can base 11 and which is formed either by plug flutes (83, Figs. 9, 10) or by a throughway in the can base located adjacent the plug hole periphery. The inlet may be closed by a solder or epoxy bead 21 which may be covered by a guard 60. The plug which has a countersunk head that may be topped by a cylindrical extension (91, Fig. 11) may be rammed home by a plunger (88, Fig. 12). The can base (30, Fig. 4) and the dividing wall (40, Fig. 4) may have central recesses for siting the patch 20 and bung 17 respectively and the wall 12 (40, Fig. 4) may be provided with a circumferential bead or series of pips for facilitating stacking prior to can assembly. For the embodiment shown in Fig. 1 the can is filled by seaming the can base 11, wall 12 and body 10 together, charging the chamber 15 with beer, seaming on the can top, inverting the can and forcing gas through the inlet to pressurize the beer and chamber 14. For the embodiment shown in Fig. 8, the can is filled by seaming the can top to the body 10, inverting the can to fill the chamber 77 with beer, seaming on the wall 71 and base 70, partly inserting the plug 81 if not already positioned and pressurizing the beer and chamber 76 using a gassing head (87, Fig. 12) The latter comprises a valved gas inlet (89) which may pass through the plug plunger (88) or through the side or end of the gassing head.

Title: Selecting circuits
IPC: G06F13/18
Filed: 1971-09-29
Abstract: 1331786 Multiprocessor system; priority arrangement GENERAL ELECTRIC CO Ltd 29 Sept 1971 [2 Oct 1970] 47004/70 Heading G4A A circuit for selecting one from several request signals occurring on respective inputs comprises several storage circuits having normal and latched conditions, several gates for applying request signals to respective storage circuits to latch the storage circuits, means responsive to a latched storage circuit to inhibit the gates and thereby prevent subsequent request signals from latching a storage circuit, and means responsive to the censation of a request signal to override the latched condition of the corresponding storage circuit and reset it to its normal condition. As described request signals, e.g. from a number of processors requesting access to, for example, a shared data store, are applied to inputs of a gating network wired to select the highest priority request by setting a corresponding bi-stable. The setting of a bi-stable inhibits a set of gates which prevent subsequent requests from reaching the circuit. The setting of a bistable also starts a timer consisting of a tapped delay line, all the taps feeding a NAND gate, which resets the selected bi-stable after a predetermined period longer than the duration of a normal request. An arrangement is provided for preventing a persistent request merely again setting the previously selected bi-stable and thus blocking out lower priority requests. If, as in the normal case, the request ceases before the timer output occurs the change is detected by a gate which resets the selected bi-stable, the circuit then being free to accept further requests. In a modification a variable priority scheme is provided. The outputs of the input inhibiting gates are connected to respective inputs 35A- 35D Fig. 6, the outputs 36A-36D of Fig. 6 being connected to the bi-stables of the gating circuit which is modified in that the priority wiring between the bi-stables is omitted. As previously when an input request ceases the inhibiting gates are enabled and the input signals are fed to a gating arrangement M1-M4. Circuit 42 applies a fixed priority to the blocks M1-M4 but the way in which the inputs are routed via block M1-M4 is variable. In accordance with a two bit number stored in register 46 decoder 41 enables one of four lines a-d which determine through which of the blocks M1-M4 the various inputs are passed. Circuit 42 passes the leftmost signal which is encoded into a two bit number A 1  A 0  at 43. The number is added at 44 to the number B 0 B 1  from register 46. The resulting sum is decoded to mark one of the four leads 36A-36D to identify the output of the priority gates 42 and may also be fed back to register 46 to determine a new priority order and thus balance the order of priority with usage.

Abstract: 1342880 Moulding dough J LYONS & CO Ltd 19 April 1971 [5 March 1970] 10653/70 Heading B5A [Also in Division A2] In a baking apparatus, a pair of metallic dies 80, 81 are juxtaposed to form a mould, electric currents are produced in the dies to heat them and thus bake a product in the mould, and the dies are separated for removal of the baked product. The un-baked product may be introduced into the mould whilst the dies are separated or juxtaposed, and the dies may be heated whilst separated or juxtaposed. The dies 80, 81 are made of iron or steel lined with copper at 86, 86a. In the described embodiment, a pair of juxtaposed dies containing a baked product is fed to a position I on a first roller conveyer 13. The upper die is then engaged by a gripper 50 which is raised to a position above a transverse roller track 54 mounted for movement longitudinally of the first roller conveyer 13. The track 54 is moved below the gripper 50 and the gripper 50 lowered to place the upper die thereon. The upper die is then moved along the roller track 54, by means of a carriage 56A having die-engaging arms 56D, 56E, to a position below a second gripper 50A. Meanwhile, the first roller conveyer 13 transfers the lower die to a second roller conveyer 14 along which the die is moved by means of a pusher 61A, 61B, the baked product being removed from the lower die at a position III. The lower die is then transferred to a third roller conveyer 10 which carries the die to a position beneath the second gripper 50A, which is then lowered to place the upper die on the lower die. The die pair is then transferred to a fourth roller conveyer 11 along which the pair is fed, by means of a pusher 71, to a heating oven at a position VII. The oven heats the dies by inducing an electric current therein and is controlled by means of an infra-red detector. The dies are withdrawn from the oven by means of an arrowhead clip 76 which engages in a recess in the upper die and places the dies on the first roller conveyer 13 and is then pivoted upwardly to release the dies. Alternatively, current is led conductively to the dies by resilient electrical contacts (155, 155A, Figs. 12 and 13) carried by arms which are pivoted by a double acting pneumatic actuator (158). The actuator (158) is controlled by a valve (161) controlled by a timing device (162) which also controls a switch 163 energizing a transformer (164) feeding the resilient contacts (155, 155A). The lower die may be fed with a sheet 123 of dough which is severed from a web 120 by a knife 124. The sheet 123 is carried on an endless conveyer which may be extended over the die by means of an actuator 126 and then retracted to deposit the dough on the die.
