Abstract: 510,556. Packeting-machines. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Feb. 24, 1938, No. 5827. [Class 94 (i)] In apparatus for filling envelopes with measured charges of powdered or granular substances, such as is described in Specification 483,162, [Group XVIII], means are provided for feeding the filled envelope to a delivery belt. The envelopes E are removed from the level of the filling station by grippers 2, 3 which embrace the bottom of the bag and are mounted on a bar 4 having a vertical extension 8 sliding in a guide 13. The jaws descend, and are opened by the actions of a pivoted cam-bar 11, which is moved by a link 15 to press on a' crank 9 on the jaw 2 and to open it against the action of a spring 56. The envelope is now level with the delivery belt 1 and is forced to the middle thereof by a horizontally reciprocable plate 34.

Title: Electric circuits for telephone instruments
IPC: H04M19/08
Filed: 1972-02-08
Abstract: 1370956 Substation apparatus GENERAL ELECTRIC CO Ltd 12 Jan 1973 [8 Feb 1972] 5851/72 Heading H4K A telephone substation including a battery recharged while the handset is on-hook includes a semi-conductor controlled rectifier connected in series with the battery in the charging path and controlled by a time constant circuit in dependence on the line voltage. As described charging of the battery 13 ceases immediately on cessation of potential at 6, 7 since maintaining potential for the controlled rectifier is removed, and charging does not re-commence until 45 seconds after restoration of the line potential by which time a capacitor 22 has charged to a level which causes transistors 24 and 25 to switch to conduction and thus re-triggers the controlled rectifier 18. The arrangement prevents the battery charging during exchange line tests &c. The microphone 1 and receiver 2 are connected across the line via hook switch contacts 3, hybrid 4 and a regulator 5. Impulsing is effected by a push-button keyboard 10, a digit store 11, pulse generating logic 12 and a switching circuit 16 including a long tailed transistor pair. The transistors 24 and 25 may be replaced by a second semi-conductor controlled rectifier directly triggered by the charge on the capacitor 22.

Abstract: 638,009. Suction cleaner nozzles. BEEDE, A. H. March 3, 1947, No. 6011. Convention date, Feb. 15, 1945. [Class 8(i)] A vacuum cleaner nozzle comprises a hollow body 10, Fig 2, having an elongated suction opening 13, a pair of spaced valve members 25, Fig. 3, pivotally mounted at 22 to move as a unit to position the valve members 25 across the length of the suction opening to confine the air flow to a limited section 12 of the opening 13, and an air outflow rocket 16 connected to a suction conduit 15 and having ears 19 pivotally mounted on pins 21 on said hollow body. The valve unit which includes a comb 27 is normally biassed by springs 23 out of engagement with the suction opening but on downward pressure on the duct 15, a downward force acting transversely through the pins 21 rocks the levers 20 and hence the valve members 25 about the pivot 22 to reduce the effective nozzle opening.
Patent GB-889806-A (GB)
Title: Improvements in or relating to control systems for industrial operations
IPC: G05B19/408
Filed: 1958-02-25
Abstract: 889,806. Automatic liquid-level control systems. SIMMONS, G. Feb. 25, 1958 [March 13, 1957], No. 6030/58. Class 38 (4). [Also in Group XXXVIII] In a chemical plant for an unspecified purpose, the level of liquid in a final storage tank is controlled by automatically starting a first feeder pump (and opening associated control valves) if the level falls below a first value, and automatically starting a second feeder pump (and opening associated control valves) if the level falls below a second value. The selection of the appropriate valves &c. is determined by a continuous loop of punched tape, which also includes instructions for temporarily shutting down one pump channel and cleansing its associated filter, if an increase in pressure across the filter shows that it is choked. The various control valves &c. are controlled by 16 " decision units " 10-25, Fig. 1, and the appropriate " decision unit " is selected for energization by a set of relays 45 that translate the 4-digit binary code of the punched tape 39 as read by the contacts 35-38, into the appropriate decimal number. All the " decision units " are basically identical, consisting of two single-pole double-throw change-over switches 10j, 10k and 10q, 10r which may be either electromagnetic relays or, Fig. 4 (not shown), saturable reactors controlled by bistable valve pairs. Each time a unit is energized, both switches change over. There are also six jacks 10d, 10e, 10h, 10l, 10o, 10t for interconnecting the units, the power supplies and the pumps &c. that each unit controls, and they are so linked as to achieve the following results. It is assumed that either pump 100, Fig. 5, or pump 101 (or both), are to supply a storage tank 115 through filters 109, 110. Starting at the point in the programme when both pumps are shut down, the next tape move tests the level in the tank. If full, the tape is stopped until the level falls. If low, the tape continues, one pump, e.g. 100 is started and its appropriate valves, e.g. 111, 114 are opened. Switches responsive to mid-tank level and back pressure across filter 109 are now brought in. If the level is high the tape stops and keeps the one pump running.. If the level is low and/or the filter is choked, the second pump 101 is started and its valves 112, 117 are opened. The bottom of the tank is now tested and if the level is low, the tape stops and keeps both pumps running, but if the level is satisfactory and a filter is choked then the choked filter is taken out of service by shutting down its pump, turning off the supply valves and opening drain and wash valves, starting up a wash pump and running it for a set time, then restoring all valves to normal service before shutting down the remaining pump. If the filters had not been choked, the wash routine would have been by-passed. The tape is now back " home " and is ready for the next round as above. It is stated that the units may be so interconnected as to control any form of industrial plant.
