Title: Simultaneous carton former and loader
IPC: B65B5/02
Filed: 1973-12-31
Abstract: 1424090 Erecting cartons around containers; feeding sheets H HAGEDORN 31 Dec 1973 60278/73 Headings B8C and B8R Apparatus for erecting cartons around containers comprises a forming section 38 and a folding section 40 arranged in succession, a conveyer 70 for feeding carton on a supporting track (62) through the sections, suction cups (115, 116) mounted, as on bars 120, 121 for vertical movement to pull the bottom carton blank in a hopper above the forming section 38 down on to the track (62) past guides 193, 206 which fold the opposed side walls of the blank upwardly, and means in section 38 for swinging end flaps of the side walls inwardly and for folding a securing panel and a top panel connected to respective sides walls downwardly on top of the containers previously fed on to the blank. The hopper has a pair of corrugated side walls 55, 56, Fig. 8, arranged to relieve the bottom blank, supported on cleats, of the weight of most of the upper blanks. The suction cups are raised and lowered by a chain 126 driven by piston-rod 143 and engaging a shaft 128 which interconnects the bottom of the bars 120, 121. A bottom layer of containers are fed from one side (or both sides) over a raisable ramp on to the blank. A second layer may be fed beneath a stabilizer plate 315 on to the bottom layer, the plate pivoting down behind the layer to stabilize it. A bar (242) and a plate (266, Fig. 9, not shown) are moved against the side walls to make them vertical and gates 150, 151 with extensions 335, 336, if there is an upper layer of container, move the end flaps of the side walls inwardly. The end flaps at one end may be moved inwardly before the containers are loaded from the other end. Gun 345 squirts glue on to the securing panel which is folded downwardly by pivoting of the plate (266). The bar (242) then folds the top panel down. The conveyer 70 is started to cause a pair of fingers 86 to push the carton into the section 40 where rods 190, 191 exerted downward pressure on the top panel and rods 340, 341 fold the end flaps of the top and bottom panels inwardly, glue being applied by guns 350. In sealing section 42 pressure is applied to the ends of the carton by belts 369 and to the top by plates.

Various conventional activators, catalysts and solvents are specified; the only lactam mentioned is lauroyllactam. The process is stated to give a fine powder product without lump formation.
Patent GB-682505-A (GB)
Abstract: 682,505. Closed solid-fuel stoves; oven stoves. PETROVITCH, L., and PETROVITCH, S. Dec. 20, 1948 [Dec. 18, 1947; June 29, 1948], Nos. 32887/48 and 32888/48. Class 126 [Also in Group XIII] In a solid-fuel, air-heating stove, Fig. 6,. having a central combustion chamber 4 and a down-flue at each side, the combustion chamber is separated from the fuel reservior 6, which is at the back, by a partition 20, 21, which is movable to the position 21<SP>1</SP> to increase the size of the reservior if wood is used as fuel. The partition may be replaced by a removable hopper. Some of the combustion products return from the side flues to the fire through openings with dampers 26a. Two movable inclined plates at the rear of the grade enable the gratearea to be varied. A damper 25 allows direct exhaust of hot gases when the stove is being lit. The Specification as open to inspection under Sect. 91, comprises also a stove, Fig. 2 (Cancelled not shown), in which a passage behind the fuel reservior leads gases distilled from the fuel, mixed with air from a second passage at the back, down to the grate. In another stove, Fig. 18 (Cancelled), hot gases from a burner 27 pass around an oven 29 and then down between an insulating inner casing 31 an outer casing with air ducts 1, to a rear outlet 15. A damper 24 can be moved to permit the hot gases to pass directly from the oven flues to the outlet 15. This subject-matter does not appear in the Specification as accepted.
Patent GB-2002982-A (GB)
Title: Quartz crystal timepiece
IPC: G04G3/00
Filed: 1978-08-11
Abstract: A quartz crystal timepiece is compensated for temperature changes by having two oscillators (1, 2) Figure 3 each with a quartz crystal vibrator (1c). The vibrators have different frequency- temperature characteristics A, B, Figure 2, and, in particular, the temperatures Tp at which the temperature coefficient is zero are different. A frequency comparator (3) compares the frequencies of the output signals of the oscillators and produces a comparison signal (3j). The comparison signal is fed to a frequency selection circuit (4) which passes the output signal with the higher frequency to further circuitry of the timepiece whilst blocking the output signal from the other oscillator. Owing to the form of the characteristics A, B selecting the higher frequency produces a resultant as indicated by the heavy line in Figure 2. <IMAGE>

Title: Attenuator
IPC: H03H7/24
Filed: 1979-05-25
Abstract: A programmable balanced electrical attenuator comprises pairs of juxtaposed units, one unit of each pair being supported on an insulating substrate (1) and the other unit of each pair being supported on another insulating substrate (2). The substrates are separated by a spacer (3). Each unit comprises interconnected film resistance elements (e.g. 5, 6, 39). Input and output terminals (17, 18 and 19, 20) are used to connect the assembly to an external circuit. Extending from the top face of the assembly are terminals connected by links (42, 43, 44, 45, 46, 47) which short circuit individual units. For programming, selected pairs of links (43, 46) are severed for one or more chosen pairs of juxtaposed units, and intermediately located third terminals (25, 34) in the chosen pair of units are bent and soldered together. Pairs of units so treated each form balanced attenuators and contribute a chosen level of attenuation to the assembly. The assembly may be reprogrammed by reconnecting severed links and separating the soldered terminals. <IMAGE>

Title: Variable resolution radar apparatus
IPC: G01S7/292
Filed: 1980-05-10
Abstract: A need has been found to reduce the angular resolution of a radar receiver in conditions of particularly heavy clutter and/or when signals are being received from close ranges. In the illustrated system the output of a detector (9) is passed through a delay line (10) and various taps from this delay line are fed to a combiner (11). The delay between taps is equal to the pulse repetition period of the transmitter (1, 2 and 3) and the effect of the delay line (10) and combiner (11) is to reduce the resolution. The amount of reduction in resolution is controlled by the settings of variable attenuators A0, A1, A2, A4, A5 and A6. These settings are determined by voltages provided at various taps on a potential divider (13). The voltages at these taps are, in turn, controlled by the voltage at (13A) which depends (a) on a signal from circuit (14) which indicates the range of the targets from which signals are currently being received and (b) on a signal from circuit (15) which represents the amount of clutter in the received signal. <IMAGE>
