Abstract: 1,090,405. Lubricating spinning-spindles. JAMES MACKIE & SONS Ltd. July 9, 1964 [July 26, 1963], No. 29763/63. Heading DID. Spinning or twisting apparatus comprises a number of spindles 1 each supporting a bobbin carrier 8, each formed with a longitudinal bore 3 for the passage of oil, and each extending from a supporting base providing a bearing surface for friction pads 10 on the carrier together with an oil reservoir extending laterally beneath the hearing-surface and beyond the inner edge of this surface. As shown, the base itself is formed as the reservoir and is bolted by flanges 15 to the side walls of the ring-rail 16. The reservoir is extended laterally to occupy almost the full width of the bobbin-rail to give a large oil capacity. The reservoir may be rectangular in cross-section with one side curved and, in the case of spindles at the end of the row, the opposite side of the reservoir is recessed to accommodate a pin to locate the rail relatively to the lifter brackets. The spindle need not be mounted centrally of the reservoir. The bobbin rail may constitute an oil trough, the reservoirs being dispensed with or being disposed within the trough to communicate with it by passages.

Title: An apparatus for producing piles, posts and similar objects of concrete
IPC: B28B7/24
Filed: 1949-11-22
Abstract: 679,134. Moulding concrete piles, posts &c. AB SKANSKA CEMENTGJUTERIET. Nov. 22, 1949 [Jan. 7, 1949], No. 29809/49. [A Specification was laid open to'inspection under Sect. 91 of the Acts, May 24, 1950.] Class 87(ii) Concrete piles, posts &c. are cast in a compartment mould defined by a sliding form which has a depth greater than that of the piles and which, when a set of piles has been cast, is raised to enable another set to be cast on the first set, and so on. The sliding form consists of a rectangular frame 1, divided by partitions 2 into a number of compartments 3. The casting bed consists of a number of plinths 4 arranged in rows, the partitions 2 being lowered into the intermediate spaces between the rows. The lengths of the posts &c. cast is determined by the position of cross shutters 5 (not shown in Fig. 1), which extend between adjacent partitions 2 and fit into the transverse gaps between the plinths 4. Gaps not occupied by crossshutters 5 are covered by plates. The partitions 2 and shutters 5 are tapered and may be built up of two plates welded at their top and bottom edges to longitudinal members. Separating sheets, as of cardboard, are laid on each set of piles before the next is cast on them. The frame is raised between successive castings by means of a crane or a set of jacks. A number of casting beds may be arranged side by side and a travelling crane used to move a casting form or forms from one to the other. Pile shoes and heads may be positioned in the moulds before casting. Cages of reinforcement may be supported in the moulds on concrete blocks which are subsequently cast into the posts.

Title: Safety device for preventing the return of oxygen and backfiring into a gas piping
IPC: A62C4/02
Filed: 1937-11-02
Abstract: 494,374. Fluid actuated valves; gas mains. TORNOW, M. Nov. 2, 1937, No. 29958. [Classes 54 and 135] A safety cut-off device for preventing the return of oxygen and backfiring into a gas piping system c, particularly one supplying acetylene gas to an oxyacetylene burner on the outlet-pipe d comprises a pair of valves a, m, arranged in series and actuated by independent diaphragms e, f respectively. Return of oxygen from the burner causes an increase in pressure in the outlet-pipe d, which acts, through a nozzle-ended pipe k, above the diaphragm e, so as to close the valve a in the same direction as that of the flow of acetylene gas, cutting off the latter. The weight of the valve a assists the closing movement. Backfiring creates a violent pressure increase in the outlet pipe d which acts under the diaphragm f to raise the valve m, again cutting off the acetylene supply, the closing movement taking place in a direction opposite to that of the flow of acetylene gas, and being against the weight of the valve m. The latter is not connected with its diaphragm and is frictionally guided in the casing. Between the outlet of the valve m and the chamber below the diaphragm f is a pipe o through which the acetylene gas passes on its way to the diaphragm-chamber and thence to the outlet-pipe d. The purpose of the pipe o is to ensure that the backfire will have had sufficient time to close the valve before pressure reaches the upper side of the diaphragm via the pipe o. The diaphragm f may be of lead and e may be of rubber, strengthened by plates r. Specification 490,929 is referred to.

Title: Smoke detector
IPC: G08B17/103
Filed: 1975-07-17
Abstract: 1504009 Photo-electric smoke detector GENERAL SIGNAL CORP 17 July 1975  [17 July 1974] 30060/75 Heading G1A A photo-electric smoke detector comprising a light-tight housing containing a light source 34 e.g. a light emitting diode and two photo-resistors 36, 38, the former normally receiving more illumination than the latter but the circuit being designed so that voltages applied to a comparison device are equal in the absence of smoke; increasing smoke density causes the illumination of the first detector 36 to decrease relative to that of the second 38, causing a voltage imbalance and operation of an alarm. Air is drawn into the enclosure via apertures 22 and passing via a labyrinthine passage, by a heating resistor 50. A lamp 54 connected in series with LED 34 indicates power on. Resetting of the circuit is by switch 59 using slide arm 58. Normally, in the absence of smoke, the voltages produced at points 96, 98 in the channels for the two resistors are balanced since the ratioing of resistors 88, 90 and the illuminations of cells 36, 38 is such that equal biasing of transistors 92, 94 is provided, so that programmable uni-junction transistor 102 does not conduct. A charge in either or both photo-resistors 36, 38, e.g. due to black and/or white smoke causes an imbalance voltage between anode and anode gate to cause 102 to fire and operate switch 72. Failure of either lamp 34, 54 results in charging of capacitor 112 above the switching level of trigger device 114 which causes alarm 64 to be operated in a pulsating manner. Testing of the system is effected by moving a wire 60 into the light path. Factory adjustment of the fractions of illumination of the two photo-resistors, preferably 2.5 to 1 (36:38) is achieved by turning and locking the axis of the LED 34, Fig. 5 (not shown) (Detector 36 has a neutral density filter 47 located in front of it). An alternative method of balancing the detector is by adjustment of a variable resistor which replaces fixed resistor 90 in Fig. 4.

Title: Improvements in and relating to control systems for electric circuit breakers and the like
IPC: H02J13/00
Filed: 1934-10-22
Abstract: 438,287. Telephone transmission systems. BRITISH THOMSON-HOUSTON CO., Ltd., Grown House, Aldwych, London. Oct. 22, 1934, No. 30299. Convention date, Oct. 21, 1933. [Class 40 (iv)] [See also Group XXXVIII] In a control system employing a carrier current of frequency different from and preferably higher than that of the working current, for selectively operating circuit breakers in any one of a plurality of feeders connecting a source of A.C. supply to a network, the distribution of the carrier current among the feeders is such that only the feeder to which the current is supplied receives sufficient to operate its circuit-breaker. Working current is supplied from the supply circuit 2 to the network 1 through a number of feeders 3 and transformers 4, each feeder having a primary circuit-breaker 6 near the main supply station or the sub-station containing the supply circuit and each secondary a circuit-breaker 5 near the network. When the circuit-breaker 6 in any feeder primary is opened by hand or by an overload relay 10, 9 operating a trip 8, contacts 29 are closed, so that the carrier current may be supplied to the primary winding 3 from the source 20 through switch 22. The corresponding high-frequency current in the secondary winding is conveyed through the network to the other feeder secondary windings but only the secondary in question receives sufficient current to operate its relay 23 by which circuit-breaker 5 is opened. To ensure that the network carries sufficient low impedance load to prevent any other feeder receiving sufficient current to operate its relay 23, low impedance byepass circuit 30 tuned to the carrier current frequency may be provided. To prevent current of normal working frequency from operating the relay 23, the connection between the transformer winding 24 and the relay coil is provided with a byepass circuit 25 tuned to the working frequency and/or a blocking circuit 26 also tuned to the working frequency. The relay 23 closes contacts 28 which complete a circuit through a winding 12 operating a trip 13 which allows the circuit-breaker 5 to open. When the feeder is again brought into operation by closing circuitbreaker 6, the carrier current is cut off by the opening of contacts 29 and the current of working frequency in the secondary passes through the closing coil 11 for the circuitbreaker 5 which is then held closed by the trip lever 13. In the event of a fault in a feeder 3 causing a large reversal of energy through the corresponding circuit-breaker, the reverse power relay 15 having a current coil 17 and a potential coil 16, closes contacts 21 so that the circuitbreaker 5 is tripped and opens. In a modification, a single transformer winding replaces the windings 18, 24.
