IPC: B31B155/00
Abstract: 132,079. Robinson, E. S. & A., and Duerden, S. Sept. 24, 1918. Paper bags, making. - Relates to flat-bottomed or satchel - shaped bags which are formed from one piece of material having infolded side gussets or tucks and a folded bottom closure extending practically straight across the width of the bag. In order to avoid the difficulties which attend the creasing of the finished bag when varying thicknesses of paper have to be acted on owing to the presence of the folded closing-flap, the diagonal and transverse creases d, h, Figs. 5 and 6, which facilitate the opening of the bag into its rectangular form are formed in the paper tube or web from which the bag is made before the blank is severed. The paper tube a, Fig. 1, is forwarded by rollers b, b<1> to a cutting-device c and the severed end passes forwards to rollers e, e<1>, f, f<1> which form the diagonal and transverse creases, after which the tube is severed at the required length and the end is pasted and folded. When the paper web is creased before being formed into a tube, the rollers for making the diagonal creases may be so arranged, Fig. 8, that the creases will occur only inside the gusset portion of the tube,

Filed: 1975-04-01
Abstract: 1512964 Liquid heaters W M STILL & SONS Ltd 31 Dec 1975 [1 April 1975] 13341/75 Heading F4A In a liquid heating apparatus for a coffee making apparatus two liquid sensing probes are provided, a first probe 18 being positioned to be contacted by liquid during its passage from an inlet hopper 2 into a heater chamber 10 and a second and liquid level probe 26 being connected through a switch mechanism (not shown) for a heating element 22 positioned in the heater below the liquid level probe 26 and arranged to heat the liquid in the heater chamber 10 so long as the liquid in the heater chamber 10 is at a level to contact the second probe 26 to energize the heating element 22. The first probe 18 is located in a probe pocket 14 through which liquid flows through an orifice 12 in the inlet hopper 2. Once water in the heater chamber 10 has reached the required temperature the level of water in the heater chamber 10 is such that it starts to flow down a siphon tube 30 positioned through the bottom wall of the heater chamber 10. The upper end of the siphon tube 30 is open to the chamber beneath a cover 32 and the lower end of the siphon tube 30 is open above a diffuser plate 34 which acts to spread the water over a bed of coffee 36 in a coffee container 38. A perforated spray plate 40 may be employed. Once the inlet hopper 2 has discharged all the cold water through the probe pocket 14 into the heater chamber 10, the first probe 18 is uncovered and this acts to break the circuit to the switch device to switch off the heating element such that energy is consumed only during the period between the introduction of cold water and the final discharge of hot coffee liquor and no hot water is maintained in the heater chamber 10 between charges of cold water into the hopper 2.

IPC: G05F1/247
Filed: 1955-05-10
Abstract: 787,837. Transformers. STANDARD TELEPHONES & CABLES, Ltd. May 10, 1955, No. 13485/55. Class 38 (2). An alternating current regulating device has in each phase A, B, C two pairs of coils 1, 3 and 2, 4, the coils 1, 2 being primary coils and connected in series aiding relationships; the coils 3, 4 being secondary windings and connected in series opposition, a movable short-circuited coil 5 being provided which is moved in turn into inductive relationship with the pair of coils 1, 3 and 2, 4 whereby by changing the position of the movable coil 5 the output A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP> of the device is varied slowly and continuously between. zero voltage and a maximum voltage, whilst the device is supplied with a constant input voltage. The primary and secondary coils are represented in Fig. 2 by 6a, 6b, 6c, the movable coils 5b, 5c being mechanically secured together by means of straps 9, 10, the coils 5b, 5c being movable together with coil 5a by means of a sprocket chain 11. Movement of the coils is effected by means of an electric motor 13, a clutch 15 and a sprocket chain 17. When the coil 5a is at the top of its column and the coils 5b, 5c at the bottoms of their columns, the output of the device is zero (by virtue of the fact that the minimum voltage from the coil 3 is made equal to the maximum voltage from the coil 4) whilst the maximum output position is as shown in Fig. 2. When in the maximum output position the device acts as a constant voltage regulator by the provision of an astatic relay which determines any small voltage changes and causes the motor 13 to operate to eliminate the changes. When a fault occurs, the clutch 15 releases and the device returns quickly to the zero position by the influence of gravity on the coils 5b, 5c. The coil 5a is also attached to the coils 5b, 5c by means of a centrally pivoted member so that the coil 5a returns to the top of its column under fault conditions even if the chain 11 fractures. The coils will be returned to the minimum voltage position by magnetic forces should the clutch stick. Start and stop switches-either manual or automatic-are provided. Specification 787,838 is referred to.

Abstract: 118,699. Stevens, W. A., and Sankey & Sons, J. Sept. 24, 1917. Controllers, drum; systems for continuous - current motors only.-In electric transmission systems for motor vehicles, mills, &c. in which a prime moves drives a generator supplying the working motor, the generator is designed for supplying. at times a lighting, arcwelding or like load by being compound wound, the generator series field f being used as a shunt to the motor series field m when the motor is driving in the forward direction. With the motor at work a variable resistance g consisting of sections in parallel is placed in series with the generator series field, and the generator shunt field c and variable resistances c<1> are placed across the motor armature. The reversing controller consists of the four cross-connected fixed contacts v, w, x, y, and two segments t, u, on a spindle s, the segment t being connected by the flexible lead 3 to the controller terminal n connected to one of the generator brushes. As shown in Fig. 1, the controller is in the forward drive position. When a lighting &c. load is to be supplied, the shunt field is placed across the generator armature by a separate two-way switch, and the controller is put in neutral position; the motor field is then short-circuited, the motor armature disconnected by the segment u and the variable resistance g is placed in shunt to the generator field, the supply being taken from the terminals 9, 10. In the reverse drive position the generator series field is shunted by the segment t and conductor t<1> of comparatively low resistance., some current still flowing through the field f. The movable contact h of the resistance g may in addition to a hand control be moved by the brake pedal on a vehicle or a separate pedal corresponding to the clutch pedal; this pedal may be interlocked with the change speed lever so that the latter cannot be moved until the generator series field is broken.

Title: Improvements in or appertaining to Machines for Filling Bottles, Jars, Cans and other Receptacles with Liquid or Semi-liquid Substances.
Inventor: ROBERTS THOMAS
IPC: B67C3/28
Filed: 1917-09-25
Abstract: 118,486. Roberts, T. Sept. 25, 1917. Bottling; filling jars, cans, and like vessels.- Relates to machines for filling bottles, jars, cans, &c. with liquid or semi-liquid substances, and of the type described in Specification 1538/06 in which the filling-valve is opened by a hand or foot lever which is held in the raised position by a spring- controlled bolt which is automatically withdrawn to release the lever on the completion of an electric circuit after a receptacle has received its supply of liquid. Instead of a spring for retaining the bolt c, Fig. 1, in locking engagement with the valve-operating lever a, a solenoid or electromagnet d is used. The rounded end of the bolt c engages a curved part of the lever a, so that when the circuit is broken on the movement of the scale-pan after the receptacle has received its supply of liquid, the weight of the lever a will readily push the bolt c away. A spring e forces the armature c<1> towards the cores of the electromagnet, and projecting parts on the armature may bear against the cores of the electro-magnet. In a modification, Fig. 3, the lever a is held in the raised position by a pivoted catch h having a notch h<3> engaged by a spring-pressed finger k. When the circuit is broken, the spring k<2> forces the finger k away from the notch h<3> and liberates the catch h, which is then turned on its pivot by the weight of the lever a, a spring h<4> limiting the movement of the catch. Fig. 2 shows a pivoted lever m connected to the core d<1> of a solenoid d and engaging a notch c<2> in the spindle of the locking- bolt c. When the circuit is broken, the weight of the lever a or the action of the spring on the filling-valve causes the disengagement of the lever m, thus releasing the bolt c. Reference has been directed by the Comptroller to Specifications 1538/06 and 105,799.
