IPC: B25C1/04
Filed: 1974-08-08
Abstract: 1438264 Nailing machines MAX KK 8 Aug 1974 35092/74 Heading B4C A pneumatically operated nailing machine comprises a nail driving member 6 fastened to a reciprocable piston 5 which is pneumatically operated in both directions and a nail feeding piston 34 which moves transversely to the movement of piston 5 to feed nails into the path of the nail driving member 6. the nail feeding piston having a pawl 35 which cuts supporting wire 43. Nail driving piston.-Pressure air from chamber 3 is supplied to reservoir 15 and acts on a head valve 7 to move it downwardly to engage the top of a cylinder 4 (Fig. 3) and at this stage the space above the piston 5 is connected to atmosphere through a passage 5. When a trigger 16 is pressed the chamber 18 allows the space 8, through passage 14 and reservoir 15 to communicate with the atmosphere and the pressure in chamber 3 allows valve 7 to rise and pressure to be applied to drive the piston 5 downwards. When the trigger 16 is released the reverse procedure takes place and the piston is raised by pressure built up in chamber 13 which is applied below the piston. Nail feeding mechanism.-Nails 42 on wires 43 are fed from a magazine by means of a piston 34 having a nail engaging pawl 38 to feed the nails and also provide a cutter to cut the supporting wire 43 as the nail 1 is driven. A locking pawl 48 is also provided. The space 50 behind the piston 34 is connected to a quick release valve 53 which dumps air from the space to allow return movement of the piston. Magazine.-A magazine for the nailing machine comprises a bottom plate 68 which can be locked by ledges 71-73 to allow for different lengths of nails. The nails are spirally wound in the magazine and held in place by a lid 81 attached by a bayonet fitting 77, 88.

Title: Improvements in or relating to apparatus for indicating and/or controlling the levelof liquid in a container
Inventor: LEITH THOMAS ORR
IPC: G05D9/02
Filed: 1956-11-17
Abstract: 801,618. Indicating and regulating liquid levels. WEIR, Ltd., G. & J. Feb. 17, 1958 [Nov. 17, 1956], No. 35203/56. Class 123(1) An appartus for indicating and/or controlling the level of liquid in a container which automatically corrects for the apparent reduction in level which occurs when the container is tilted comprises a main container 1 having two or more auxiliary chambers such as 2, 3 spaced equidistantly about its periphery. The chambers 2, 3 are connected by a pipe 4 and contain a control liquid, which may be the same liquid as in the main container. The level of liquid in the chambers 2, 3 is maintained constant by supplying liquid thereto from respective supply tanks 5, 6, these tanks being Kept full by liquid supplied from pipes 9, 10 at such a rate that it overflows continuously over weirs 7, 8. The liquid enters the chambers 2, 3 through respective orifices 13, 14 and discharges therefrom into the container 1 through respective orifices 15, 16 which are of such size that the level in the chambers 2, 3 remains steady and constitutes a datum with which the level in the container 1 is compared. For this purpose the pipe 4 and the lower part of the container 1 are connected to opposite sides of a diaphragm 17, movements of the diaphragm responsive to changes in level as liquid is introduced into or withdrawn from the container through a pipe 21 actuating a level indicator and valves 19, 20 which respectively control the supply or discharge of liquid to restore the level to its preset value. If the apparatus is tilted, as shown in Fig. 2, the apparent reduction in level in the container 1 is approximately offset by an increase in the datum level in the chambers 2, 3, since under this condition whilst the flow into the chambers remains substantially the same, the increased outflow through the orifice 16 does not compensate completely for the reduced outflow through the orifice 15. Thus any change in pressure difference occurring across the diaphragm 17 when the container is tilted is related only to a change in the quantity of liquid in the main container as when the container is in its upright position.

Title: Improvements in and relating to petroleum and coal tar oil emulsions
IPC: C09K23/00
Filed: 1936-12-22
Abstract: Stable aqueous emulsions of mineral and/or coal tar oils, which have a high interfacial tension against water and are non-polar, are obtained by emulsifying the oils in an aqueous medium containing more than 10 per cent. of a salt of a sulphuric acid derivative of a polymerized fatty acid or a polymerized naphthenic acid.  The emulsion may be readily diluted and is not decomposed by boiling. Suitable salts are those obtained from long chain sulphonated polymerised oils containing polar groups, e.g. sulphuric acid compounds of polyricinoleic acids, di- (hydroxy-stearic) acid or mixtures thereof.  These acidic compounds are wholly or partially neutralized by bases e.g. mono-, di- or trihydroxy alkyl amines, triamylamine, guanidine or mixtures with alkali bases.  Substances which reduce the interfacial tension e.g. glycerine, tetrahydronaphthalene, ethylene glycol, sucrose, gelatine and hexahydronaphthalene may be added.  The oils to be emulsified may contain a small proportion of an oil containing a polar group. According to an example, 500 pts. of petroleum oil is added to 100 pts. of a sulphonated di-(hydroxy-stearic) acid.  The acid is neutralized by stirring in at 85 DEG  C. a molecular equivalent of monoethanolamine in 100 pts. water.  When homogeneous, 280 pts. of water containing 20 pts. of glycerine are gradually stirred in.

Title: Improvements in heilmann combing machines
IPC: D01G19/08
Filed: 1929-11-21
Abstract: 349,087. Combing-machines. G•GAUFF, C., 78, Rue de Verdun, Mulhouse, Haut-Rhin, France. Nov. 21, 1929, No. 35714. Convention date, Nov. 21, 1928. [Class 120 (i).] During the detaching operation in a Heilmann combing-machine an approaching movement is provided between the top comb d, Fig. 2, and the feed gills e or feed rollers to produce a slight stroking of the lap between the top comb and the feed device. The top comb mem. ber is connected at d<3> to a member connected by links e<1> f; l k to the nipper carriage i c. The point l is adjustable to any of the three positions l, l<1>, l<2> while the top comb member is guided by a roller d<2> engaging a fixed horizontal plane h h. In detaching, the nipper carriage i c is moved to the left by the arm i j and, owing to the inclination to the vertical of the link l k being greater than that of the link e<1> f, the point d<3> and the top comb d will move through a shorter distance than the point e<1> and therefore than the feed gills e. The end l of the link l may be attached at h for maximum difference of movement or at l<2> for no difference, l<2> k being parallel to e<1> f. In a modification, the top comb member is connected at d<3>, Fig. 3, to a lever d3 n k carrying a roller n engaging a cam surface m on the link e<1> f. In detaching, the feed of the comb d by the action of the cam m is less than that of the feed gills e, while the inclination of the comb d is slightly varied. In a further modification, the top comb member is connected at its end d<3>, Fig. 4, to a lever d<3> p k itself connected by a link o p to a lever o f keyed on the spindle of the link e<1> f. During the advance of the feed gills e rotation of the link o f produces a substantially vertical movement of the end d<3> and a slower advance of the top comb than that of the feed gills. The amplitude may be varied by connecting the link o p in any of the positions p, p<1>, P<2>.

Title: Improvements relating to the testing of selecting switches of the kind used in automatic telephone and other selective systems
IPC: H04Q1/24
Filed: 1932-12-17
Abstract: 411,190. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, both in London. Dec. 17, 1932. No. 35829. [Class 40 (iv).] The hunting or homing speed of a selector is tested by comparison with a timing switch driven at a constant speed by impulses derived from A.C. supply mains through a transformer T and rectifier R1. As shown, the selector is of the kind driven by an individual electric motor M1, M2 under the control of a latch magnet LM. In Fig. 1, the test apparatus is connected to the selector to be tested by a cord plugged into jacks SJ, TJ. Relay A energizes and starts the timing switch. A rectifier R2 prevents the operation of A if the cord is reversed. The connection of the magnet contact dm in parallel with the impulsing contact b1 ensures full energization of the magnet DM while relay B is back. In position 10, relay P (i) energizes and connects up the latch magnet LM to start the selector, while in position 11, relay Q pulls up and holds A. When position 10 is reached again, P falls back due to current through its opposing winding P(ii), and the selector stops, while the timing switch steps on to normal by selfinterruption. The position of the selector is then noted. Relays A, Q hold until the cord is removed. In Fig. 2, the test apparatus is associated with a routiner RT, and the selectors are assigned for testing by a switch AS. Relay TA energizes followed by B, and the timing switch steps as in Fig. 1, relay P operating in a particular position to start the selector under test. TA falls back on the change-over of off-normal contacts ON, connecting up F, and on re-operating as the selector again passes the normal position TA connects up Q, which causes the selector to stop on reaching the normal position after the second cycle. TA operates and a circuit F, N or S is closed according as the speed of the selector is fast, normal or slow. The apparatus restores on opening of contact x in the routiner. The apparatus may be modified for testing the selectors over three or four cycles instead of two. Moreover two timing switches stepping at alternate half-cycles of the A.C. supply may be employed. The Provisional Specification refers to the use of an electrically driven tuning fork as the source of impulses.

Abstract: 1317691 Protective arrangement TAFT ELECTROSYSTEMS Inc 2 Aug 1971 [4 Sept 1970] 36272/71 Heading H2K A self resetting fault indicating arrangement for a power transmission line comprises an indicator 17 with a coil 36, Fig. 2, for establishing a magnetic field to move a magnet 37 to the normal position (shown in Fig. 2) in response to current in one direction, or to the fault indicating position in response to a larger current in the opposite direction, and a circuit, Fig. 1, operative to provide the current in the one direction when the current in the line is normal and in the opposite direction when the current in the line is abnormally high. In Fig. 1 the line current induces a current in a sensing coil 12 or transformer secondary winding, the induced current normally flowing on alternate half cycles through a diode 14 and the coil of the indicator 17 in the direction of the arrows 15, a controlled rectifier 30 being non-conductive on the other half cycles. When the line current becomes excessive, a zener diode 25 breaks down to trigger the rectifier 30 into conduction so that a larger current flows in the direction of the arrows 31 and causes the magnet 37 in the indicator to turn to its fault indicating position. A permanent magnet 43, 44 retains the magnet 37 in each of its positions, a projection 42 on the magnet co-operating with stops 40, 41 to limit the movement of the magnet 37 which can bear indications or operate contacts. An alternative circuit and a constructional arrangement are illustrated, Figs. 4 and 5 (not shown).
