Title: Apparatus for labelling articles
IPC: B65C9/18
Filed: 1975-02-13
Abstract: 1500528 Labelling articles FR HESSER MASCHINENFABRIK AG 13 Feb 1975 [14 Feb 1974] 6105/75 Heading B8F Apparatus for labelling articles 2 comprises a rotatable spider 13, a label carrier 15 adapted for carrying a label by the use of suction mounted on the spider by means of a pivot 16 disposed transversely of the axis 12 of the spider, an article conveyer 3 arranged to convey articles past the spider along a path which is tangential to the rotational path of the spider, provision for enabling the distance between the travel path of the articles and the spider to be adjusted so as to maintain a space between the carrier and the articles, and a control gear for pivoting the carrier to and from a preselectable delivery position T whereat, in use, a label is discharged from the carrier to an article by compressed air. Labels 10 are drawn from a supply roll 11, Fig. 2, and may be printed in a label feed device 4, the printer being remotely controlled by means of a price-calculating balance. The label carriers are provided with nozzle orifices 17, Fig. 1, for enabling retention by suction and discharge by blowing of the labels. Movement of the articles along a conveyer belt 8 past a photo-electric device 18 triggers a pulse which switches on a time delay switch 21. After a predetermined period of time selectable by a switch 23 the change-over occurs from suction to blowing and a label is applied to an article. A further adjustable time delay switch may also be used to trigger rotation of the spider and the change-overmay occur during rotation of the carrier about the spindle axis (12) on a path 24. The distance of the axis from the conveyer belt may be adjusted to suit the size of various articles by a screw spindle to ensure that a predetermined distance is provided between the carrier and the articles for discharge of a label.

Title: Improved mine roof supports
Inventor: COWLISHAW FRANK
IPC: E21D23/00
Filed: 1956-02-28
Abstract: 854,967. Mine roof supports. DOBSON Ltd., W. E. & F. Feb. 12, 1957 [Feb. 28, 1956], No. 6108/56. Class 20(2) An advancing mine roof support comprises two hydraulic pit props 2, 3 on a skid base 19 and connected to a third prop 1 by a hydraulic advancing ram 21 and cylinder 22, a cantilever roof beam 28 being joined to the props 2, 3 by ball joints 28 and projecting between two parallel box section arms 32, 33 on the head 27 of the prop 1. The ram 21, which is pivoted to the base 19 at 21a and to the base of the prop 1 at 22a, carries a guide 15. The cantilever beam 28 comprises two box section beams 28 and 29 joined end to end by a bolt 30. In operation, the beams 28, 29 support the roof while prop 1 is lowered by a pump P operated by a handle 53 and then advanced by the ram 21 manually operated by a valve 63. Handle 53 is then operated to raise the prop 1 and the arms 32, 33 to support the roof while lowering props 2 and 3 and beams 28, 29 preparatory to their advance up to the prop 1. Alternatively a two-armed beam 28 may entrain a single arm 32, 33. The beam 29 may be braced against the roof by wedges (not shown) driven between it and the prop head 27 or by a hydraulic cylinder and ram indicated in broken line at 47. The props are centralised by resilient means in their bases. The pump P comprises a cylinder 49, Fig. 5, in which a piston 52 is operated by the handle 53. The fitting to which the handle is attached (Fig. 6, not shown, refers) comprises a control knob incorporating an air release valve operated by the fastening of the handle. Fluid is pumped from a reservoir in the base via an inlet 50 and a valve 57 to prop 1 and, through an outlet 51, to props 2 and 3. Excessive movement of handle 53 raises a pressure relief valve 60. A spring 62 cushions normal pumping movements to prevent inadvertent release of valve 60. Specification 785,470 is referred to.

Title: A boiler for a central heating system and for preparing hot water
Inventor: MUELLER WALTER
IPC: F24H9/20
Filed: 1961-02-20
Abstract: 915,145. Hot-water boilers. SCHIFF & STERN G.m.b.H. Feb. 20, 1961, No. 6128/61. Class 64 (1). In a boiler serving a central heating system and a hot water supply system, the former is supplied from an inner annular jacket whilst the latter is supplied from an outer concentric annular jacket, both jackets being traversed by axially directed smoke tubes whilst additional heating flues are disposed in the space between the jackets, some of the flues serving to heat the inner jacket whilst the remainder heat the outer jacket. In the form shown, the inner jacket 1 encloses a combustion chamber 38 fired by an oil burner 60 and is connected to the flow and return pipes 11, 14 of the central heating system by pipes 6, 7 respectively, a circulating pump 12 being inserted between the pipes 14 and 7. Gases from the combustion chamber flow rearwardly through a ring of smoke tubes 5 in the jacket 1 and then can flow forwardly through a ring of smoke tubes 31 in the outer jacket 2 which is connected to the flow and return pipes 52, 51 of the hot water supply system. Between the jackets is located a corrugated plate 32 which provides a series of outer heating flues 34 wherein gases can flow over the inner wall of the outer jacket and a second series of inner heating flues 33 wherein gases can flow over the outer wall of the inner jacket. In operation the gases flow either in parallel through the tubes 31 and the outer flues 34 to collect in a chamber 44 whence a pipe 45 leads them to an outlet 41 or through the inner flues 33 to discharge into a chamber 39 whence a pipe 40 leads them to the outlet 41, the gas flows through the pipes 45, 40 being controlled by interconnected valves 47, 46 actuated by a motor 49 in response to variations from a preset temperature in the outer jacket as signalled by a thermostat 50. Thus, if this temperature falls below, say 85 C., the valves are moved to the position shown so that the outer jacket receives the whole heating effect of the gases issuing from the tubes 5 as it flows through the tubes 31 and flues 34. If the control temperature exceeds 85 C. the valves move to close the pipe 45 and open the pipe 40, whereupon the inner jacket receives the heating effect as the gases flow wholly through the flues 33. Furthermore, a water heating coil 53 located in the outer jacket is connected between a change-over valve 56 in the pipe 11 and the pipe 14. The valve 56 is also controlled by the thermostat 50 so that if the control temperature falls below 85 C. the pipe 11 is partially closed and the connection 55 to the coil opened, whereupon the pump 12 circulates water heated in the jacket 1 through the coil, further to heat the water in the jacket 2. When the control temperature exceeds 85 C., the pipe 11 is fully opened and the pipe 55 closed. The arrangement allows the withdrawal of hot water at a very high rate. In a modification the oil burner is replaced by a solid fuel grate.

Title: Improvement in record card reproducing machines
Filed: 1946-03-01
Abstract: 608,816. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. March 1, 1946, No. 6457. Convention date, March 2, 1945. [Class 106 (i)] A record card reproducing machine comprises means for sensing alphabetic classification data on records, means for comparing the sensed data on records, means for comparing the sensed data with a representation set up in the machine, and punching means for reproducing data recorded on other record material when the comparing means registers agreement. The invention is applied to a known machine comprising a card pocket R, Fig. 1, for receiving a file of record cards 10, means for feeding the cards in succession past sensing brushes 15 for reading classification data in the cards, a second card pocket P containing unpunched cards 11, and means for feeding these blank cards in succession past punches 18. A second set of sensing brushes 16 read data in the record cards and control the operation of the punches 18 to reproduce this data in a new card. According to the invention, the classification data comprises alphabetic characters which are represented by combinations of holes in the R, X or O positions with holes in the 1-9 positions. As a record card passes brushes 15, Fig. 4b, the sensing of each hole energizes the pick-up coils of relays R58 ... R64 to which the brushes are connected. The associated contacts R58a ... R64a are closed to establish circuits for the holding coils H of the relays, and contacts R58b ... R64b of a comparing device are transferred. Classification data is set up in the machine by plugging selected sockets 205 of an emitter Em to relays R57 ... R63, the sockets 205 representing the R, X, O positions being connected through intermediary contacts RXOa, b controlled by a relay R101 which is energized during the reading of the R, X, O positions only. The arm 40 of the emitter Em passes over segments R, X, O, 1-9 in synchronism with the reading of the card by brushes 15 and transmits impulses to the pickup coils of relays R57-R63 according to the classification data represented by the plug connections. The relays R57-R63 control " b " contacts in the comparing device so that, in case of disagreement, current passes to a relay U97 which stops the feed of the blank cards. When the comparing device registers agreement, however, a blank card is fed stepby-step past the punches 18 as the controlling record card passes over the sensing brushes 16. The classification data may consist of alphabetical, numerical or partly numerical characters, e.g. " AB89," and an additional data group may exercise control, either separately or in combination with the first. Thus, a second relay U98 may be connected to a comparing network for the second data group, and the energization of either of these relays, or both together, may be arranged to stop the feeding mechanism of the blank cards.
