Title: Improvements in or relating to bag making machines
Inventor: WECH ROBERT JAMES
IPC: B31B19/26
Filed: 1969-09-11
Abstract: 1279443 Making bags FMC CORP 11 Sept 1969 [16 Sept 1968] 17763/71 Divided out of 1279441 Heading B5D In a machine for making bags from thermoplastic sheet material a vertically reciprocated heated cutting and sealing bar is raised by cam and push rod mechanism, the sealing bar being engaged by the upper ends of the push rods and there being means holding the sealing bar in engagement with the push rods. The sealing bar 340 co-operates with a sealing roll 106, and is secured to mechanism 104 mounted by trunnions 350 to blocks 352 attached by caps 402 to the push rods 382. Cams 108 on a shaft 110 reciprocate the push rods, and each cam has an adjustable ring 440 thereon by means of which the dwell can be altered. The sealing bar can be turned through 90 to an inoperative position and locked there by a spring loaded pin (Fig. 3). A bolt 400 provided with a lock nut engages a nylon disc 396 on the tops of each push rod and can be turned to provide adjustment of the penetration force of the sealing bar and moves against a graduated scale. A pneumatically operated cylinder 416 raises and lowers the sealing bar as indicated by a control circuit. The bar is lifted when the machine is being set-up; whenever the machine stops the bar lifts automatically; on starting the bar drops automatically; the bar also lifts after a predetermined number of bags have been produced to engage the bags to be removed, whereupon the machine restarts and the bar drops automatically.

Title: Improvements in or relating to wireless signalling
IPC: H04B7/02
Filed: 1928-06-20
Abstract: 292,524. Telefunken Ges. f³r Drahtlose Telegraphie. June 20, 1927, [Convention date]. Transmitting systems ; undesired signals, eliminating.-The repetition of a received signal, in short-wave systems, due to the waves travelling repeatedly round the earth, is prevented by transmitting successive signals, or groups of signals, on different frequencies and by synchronously varying the tuning of the receiver, so that by the time a signal would be received a second time (about one-seventh of a second after the first reception of the signal) the receiver is tuned to a frequency differing from that of the said signal. Either the carrier frequency or a modulation frequency may be varied; and the variation may be effected by altering the tuning of the circuit, or by selecting in succession from a number of tuned circuits bv a commutator. When heterodyne reception is employed, the frequency of the local oscillator may be varied in synchronism with the transmitter, thus giving a constant beat frequency for primary received signals, and a different beat frequency for secondary signals.

Title: Improvements in photographic bleach-fix baths
Inventor: JACOBSON KURT ISRAEL
IPC: G03C7/42
Filed: 1954-06-19
Abstract: 774,194. Photographic bleach-fix baths. PHOTO-CHEMICAL CO., Ltd. June 3, 1955 [June 19, 1954], No. 18055/54. Class 98(2) A bleach-fix bath for processing photographic colour material comprises an aqueous solution of one or more silver halide solvents and a cuprammonium complex derived from a cupric salt and ammonia or a primary or secondary aliphatic amine.. When an amine is used to form the complex this may be ethylenediamine, mono-ethanolamine or di-ethanolamine, and it is preferred to use excess of the same or a different amine used to form the complex. A sequestering agent such as ethylenediamine-tetra-acetic acid may be added to the bath. The silver halide solvent may be sodium or ammonium thiosulphate, and an additional silver halide solvent may be included such as an alkali metal or ammonium thiocyanate. The cuprammonium complex may be formed in situ in the bath by adding the ammonia or amine to a solution of the cupric salt and the silver halide solvent. Any stain produced on the photographic material by the baths may be removed by rinsing the material in a weak acid bath such as 1 per cent acetic or citric acid.

Fig. 8 shows a mounting in which the grinding wheel spindle is radially adjustable with respect to the shaft 13 about which it rocks which shaft is itself vertically adjustable in a slot 37. in a stand 26. The adjustments are effected by a screw, the rotation of which adjusts a swinging member 23 in one with the shaft 13, and a member 22 which carries the wheel spindle 11 and slides on the member 23. The part 42 of the screw engages a nut 43, the position of which relative to a flange 40 indicates the diameter of drill for which the adjustment is made. The adjustment of the shaft 13 is effected with the swinging member aligned with an extension 26b of the stand having a spring catch 39 for engaging a nut 38 on the screw part 28. The part 24 engages a nut 53 which can slide relatively to the member 22 and be secured thereto by a set-screw.

The ratio of the length L of the movable blade part to the blade pitch T is preferably greater than 1: 0 and the angle y greater than 180 degrees so as to obtain a favourable channel shape at partial load. The pivoted blade parts are moved in unison by a ring 21. The inner supporting ring is made in two halves 10, 10a so that the inner ends of the blade parts 11 may be provided with pivot pins 17. Cooling air may be supplied to a cavity 23 formed in the fixed blade part 8 and discharged therefrom through gaps 12, 13. A cavity 26 formed in the movable blade part 11 may be supplied with cooling air from the cavity 23 through the duct 27. Cooling air is discharged from the cavity 26 through the ducts 28, 29, 30.

Abstract: 723,374. Fencing. ADAMS & BENSON, Ltd. July 22, 1953. [July 22, 1952] No. 18456/52. Class 45.  An appliance to which fencing wire can be anchored comprises a grab having a pair of arms 1, 2 pivoted together intermediate their ends and which are shaped on one side of the pivot 5 to form jaws 3 for gripping, clamping, encircling or taking hold of various objects, and a coupling device having an eye or eyes 10 for engaging over an arm or each arm so as to be frictionally gripped by a tilting action caused by a pull on the coupling device, the arm or arms being adapted to slidably receive the eye or eyes of the coupling device. Each jaw has a triangular plate 6 welded to its inner side with its point towards the mouth of the jaws to help it to engage the ground. The arms on the other side of the pivot are straight. The coupling device consists of an insulated sleeve 8 which is adapted to be connected to the fencing wire by a member 11 through a wire strainer of the type disclosed in Specification 691,326. The sleeve is mounted on a wire link 7, the link 7 being connected to the eyes 10 by links 9. One of the arms is longer then the other and can be made in two parts joined by an insulating sleeve. This arm can be used as a temporary fencing post, and when it is used as such the eyes 10 are both attached to this elongated arm. Otherwise one eye is engaged with each arm so that the tension in the fencing wire tends to pull the arms together to make the jaws 3 grip more tightly.

Movement of the members together puts the pin 16 at the right hand side of arm 14 of the slot, Fig. 2, this prevents locking and causes the pin to engage edge 27 of any notch to prevent unlocking. A boss 28 is provided to help to move the pin to the right when the members are brought together and an outer plate (19, Figs. 5-7 not shown) overlies the outer member, has a similar L-shaped slot to the inner member, and is connected to the inner member by pins 20, 21 to move with the member. The spring 17 is connected to this plate.

Abstract: 1,178,160. Steam traps. K. FUJIWARA. 21 April, 1967 [22 April, 1966], No. 18581/67. Heading F4U. A thermodynamically actuated or " floating disc " type of steam trap includes a bimetal ring arranged so that under the influence of cooling caused by air binding it co-operates with a fixed conical surface to raise the valve disc. As illustrated, the valve disc 2 is located in a pressure chamber P connecting inlet and outlet chambers A and B, and a broken bimetal ring 5 which expands when cooled, rests on a surface N of which the inner part is conical and the outer part plane. When the ring 5 is fully cooled to raise the disc to the position shown, it rests on the plane portion of the surface N so that it cannot be depressed by the weight of the disc 2. Upon the passage of steam, the ring contracts and descends below the valve disc seats D and E to allow the resumption of normal operation. In other embodiments, Figs. 4-12 (not shown), the conical surface may be of opposite sense and the ring may contract on cooling, and the conical surface and ring may be located between the two valve seats.
