Title: Packaging method and apparatus
IPC: B65B9/20
Filed: 1968-07-15
Abstract: 1,223,879. Wrapping-machines. MIRA-PAK Inc. 15 July, 1968 [19 Dec., 1967], No. 33551/68. Heading B8C. A method of forming packages wherein a continuous web 10 of packaging material passes through a fixed former 12 where a sealing member 13 seals the opposite edges of the web to form a tube 14, and individual packages are formed from the tube by spaced transverse seals made by a pair of sealing jaws 15a, 15b, is characterized in that the former 12, and a mandrel 20 disposed in the tube 14, are moved relatively to one another to cause, in a continuous operation, the mandrel 20 to engage the first formed transverse seal 32 to draw a length of tube through the former and shape the end of the tube with a uniplanar bottom so that the subsequently formed package can stand on the flat base. The mandrel 20 has a cross-sectional shape dependent upon the desired configuration of the finished package. As shown, after a filled package A has been severed by a knife 16a and slot 16b in the sealing jaws 15a, 15b. The mandrel 20 is lowered to pull down a further package length B and flatten its base the latter being consolidated as a pivotally mounted platten 40 is raised to co-operate with the lower end of the mandrel 20. Adhesive may be applied to the seal 32 and the platten 40 may be heated. The product is introduced into the part B of the tube through the hollow mandrel 20 which is moved upwardly above the sealing jaws 15a, 15b which are subsequently then moved inwardly to form a transverse seal at the top of package B and at the bottom of the next package C. The platten 40 is then lowered and the cutters 16a, 16b are operated to sever the package B whereupon the jaws 15a, 15b are separated and the cycle is repeated. A gussetted type package may be formed by gusset bars (33), Fig. 1A, not shown, and means such as rollers, not shown, may be applied to the outer face of the tube 14 to crease the material more precisely. The position of the longitudinal seal in the tube 14 may be changed by changing the relative circumferential orientation of the former and the sealing jaws 15a, 15b.

Title: An anticipatory warning device for motor vehicles
IPC: B60Q1/44
Filed: 1964-08-18
Abstract: 1,023,566. Fluid actuation of switches. R. SCOTT. Aug. 18, 1964, No. 33642/64. Heading H2B. A device to give advance warning of braking comprises a pressure-sensitive switch connected to the air inlet manifold of an internal-combustion engine. The switch comprises a casing 12 divided into two cavities 1, 2 by a pressuresensitive element 3, e.g. a bellows piston or diaphragm, the cavity 2 being connected to the inlet manifold of the engine by a pipe 14 and to the cavity 1 by a narrow pipe 15 with an adjustable screw 16 therein. In operation, with a steady throttle setting the pressure sensitive element is undeflected because the cavities 1 & 2 are at the same pressure. If the throttle is suddenly opened element 3 is raised and may actuate contacts or a microswitch 5 connected to signal lamps. After a delay the pressure in cavities 1 & 2 is equalized via pipe 15 and the element 3 returns to its original position. If the throttle is suddenly closed, as in braking, the cavity 2 is evacuated and element 3 is lowered to actuate contacts or a microswitch 6 connected to a brake light. The microswitches are adjustably mounted.

Abstract: 1275192 Radar SELENIA INDUSTRIE ELETTRONICHE ASSOCIATE SpA 10 July 1970 [15 July 1969] 33675/70 Heading H4D In an M.T.I. pulsed Doppler radar, interference from wide-band jamming is reduced by placing in the video signal output circuit of coherent phase detector 3 and M.T.I. canceller 4, a first video amplifier 5 having a bandwidth B<SP>1</SP> wide enough to pass wide band system noise and jamming noise and clutter remnants as well as the target signal, a hard limiter 6 having a limiting threshold well bellw the R.M.S. value of the noise and target signal but above the clutter valve, to produce wide band noise and narrow band target signal at the same level together with much smaller amplitude clutter (15 db below), and a second video amplifier 7 having a narrow bandwidth b which passes substantially all the target signal but severely attenuates the noise. The signal E thus has a large signal and negligiable noise and clutter, the noise being at a greater amplitude than the clutter. 8 and 9 are in amplitude detector and an integrator respectively the latter operating selectively on the noise and clutter such that they acquire the same amplitude to give a uniform background for the target marks.

Title: Magnetic switching devices
IPC: H03M7/16
Filed: 1953-12-03
Abstract: 744,115. Non-contact-making relays. RADIO CORPORATION OF AMERICA. Dec. 3, 1953 [Dec. 22, 1952], No. 33676/53. Class. 40(4). [Also in Groups XIX and XXXVIII] Information for storage in a magnetic matrix memory of the kind described in the publication R.C.A Review, Volume XIII, June 1952, is applied in binary form to selected input leads of two sets of saturable magnetic cores, information applied to one core set causing a single core to change its magnetic polarity while further information applied simultaneously to the second set marks a single core in each of a number of core groups, the arrangement being such that each core in the first set is associated by transfer coils with a particular group of cores in the second set, the change of magnetic polarity of a single core inducing a pulse in a transfer coil which causes a corresponding polarity change in the marked core of the associated group whereby a pulse for setting the matrix memory is induced in a particular output coil. Initially all the cores have an " N " magnetic polarity, but when a code signal is applied to a single input lead of each of three pairs of leads 1A, 2A, 3A, Fig. 1, core windings L1, L2 in the first core set A are so energized that a single core selected by the code changes to a " P " polarity and induces a pulse in its transfer coil OA. Similarly, in the second set B, a single core in each of the groups BS1- BS8 is selected by a further coded signal applied to input pairs 1B, 2B, 3B. In this case the selected cores are unmagnetized, the remaining cores being inhibited by magnetization in the " N " direction. Since the transfer winding pulse is applied to only one group of cores, a single unmagnetized core is changed to a " P " polarity and induces an output pulse in its associated output coil OB. To reset the arrangement, all the cores in set A are strongly energized in the " N " direction by current through a restoring winding R. A strong transfer pulse is induced by the reset core which reverses the polarity of the " P " magnetized core in the second set. In an alternative arrangement, Fig. 3, having fewer windings on each core, the coded signal applied to the first core set inhibits all cores but the one required by magnetizing in an " N " direction. Reversal of the single selected core is then effected by a " P " magnetizing coil R common to all the cores. The restoring winding is omitted in the arrangements shown in Fig. 4 and Fig. 5 (not shown). These arrangements have 4 input pairs of leads 1D-4D selectively controlling sixteen cores D1-D16 and correspond to the first core set A shown in Fig. 1. To restore to the normal " N " condition, both leads of input pair 4D are energized simultaneously. A decimal binary arrangement is shown in Fig. 6, comprising sets F and G of 10 and 100 cores, the latter grouped in tens. Since 4 pairs of input leads 1F-4F and 1G-4G are provided for each set, the code available is not used completely.
