Patent GB-110898-A (GB)
Title: Improvements in and relating to Hand Stapling Machines.
Inventor: JEFFAY LOUIS SAUL
IPC: B25C5/16
Filed: 1917-08-02
Abstract: 110,898. Jeffay, L. S. Aug. 2, 1917. Stapling.-In a stapling-machine, a strip H of connected staples is fed by a forked feed member N loosely mounted on a helical spring P secured at its rear end in a recess A<1> in the machine frame. When the usual spring plunger B is driven downwards to shear a staple from the strip and drive it through the work, a cam I acts on a pivoted pusher bar K to force back the feed device so that it slides over the strip ; on the return of the plunger, the spring P causes the member N to engage the strip and feed it forwards. A forked check spring Q mounted on a pivot R prevents backward movement of the strip. For severing the staples from the strip, the lower end of the plunger co-operates with a fixed cutter bar F having a bevelled cutting edge.

Title: Improvements in or relating to synchronised clock systems and secondary clock therefor
IPC: G04C13/03
Filed: 1930-04-09
Abstract: 344,693. Electric clocks. INTERNATIONAL TIME RECORDING CO., Endicott, New York, U.S.A. -(Assignees of Bryce, J. W. ; 160, Willard Avenue, Bloomfield, New Jersey, U.S.A.) April 9, 1930, No. 11294. Convention date, May 2, 1929. [Class 139.] Synchronizing.-A clock system in which a single line is used for the normal timetransmitting impulses and for synchronizing impulses, is characterized by the inclusion in the secondaries of magnets with multiple windings and means in the secondaries for controlling which of the windings shall be energized according to the time indicated by the secondaries. The invention particularly relates to systems of the kind described in Specification 261,258, [Class 139, Watches &c.]. In the master clock, contacts 14, 16 are closed once an hour, contacts 17 once a minute, and contacts 19 are closed by the escapement 11. With switch 32 in the normal position shown, an impulse is sent once a minute through circuit G, B, 32, 33, 17, 34, G (or metallic return if desired). Magnet 34 closes contacts 35 and a low voltage impulse is sent to the secondaries through circuit G, B (in part), 42, 43, 45, 35, 37, secondaries, G. Just before the 59th minute of the hour, contacts 16 close for thirty seconds and, through quick-closing contacts 19, rapid impulses are sent to step up any slow secondaries. At the 59th minute contacts 14 close to open contacts 43 and close 43a so that a high voltage impulse is sent to the secondaries, to restart them all in correct time, through circuit G, B (full), 43a, 45, 35, 37, G. The midposition of switch 32 is for retarding all clocks, and the upper position for stepping-up all clocks. At each secondary 21, the ratchet 22 on the minute hand arbor 20 is actuated by pawl 21 and a magnet with two windings 21c, 21d. A cam 50 on arbor 20 opens contacts 51 when the secondary indicates the 59th minute. During normal working contacts 51 are closed and short-circuit winding 21d so that at each low voltage impulse, once a minute, the winding 21c and pawl 21a advance the clock. When contacts 51 open winding 21d opposes 21c and the low voltage impulses are unable to advance the clock (e.g. the clock may be fast). The secondary then remains stationary until, at the 59th minute of the master clock, a high voltage impulse is received over line 37. In this case the voltage, in spite of the opposition of 21d, is sufficient to actuate 21c and 21a and restart the clock on time. Examples of suitable voltages, resistances, and turns of windings 21c, 21d are given. Synchronization may occur more often than once an hour by suitably arranging the contours of the cams 15, 12, 50.

Title: Exhaust gas recirculation flow control system
IPC: G01M15/11
Filed: 1974-03-14
Abstract: 1429123 Automatic control of speed BENDIX CORP 14 March 1974 [29 March 1973] 11448/74 Heading G3R [Also in Division F1] The roughness (cyclic speed fluctuations) of an internal combustion engine is regulated by controlling the engine exhaust gas recirculation flow to a first value if the roughness is below a pre-set level, and to a second (lower) value if the roughness is above the pre-set level. As shown, an internal combustion engine 10 has a recirculation system 80, controlled by a butterfly valve 90. This valve is controlled by a system 40 also, Fig. 3 (not shown) in which an engine speed sensor 42 generates an output having high and low frequency components dependent respectively upon engine roughness and engine speed changes as required by the driver. Circuit 44 allows a certain range of frequencies from sensor 42 to pass, these signals, being differentiated to form a roughness signal, dependent upon the derivative of the engine speed, that is compared at 50 with a pre-set threshold. Integrator 56 ramps up or down, according to whether the threshold is larger or smaller than the measured roughness, to open or close the recirculation valve 90 and maintain the roughness at the threshold value at which harmful components (nitrous oxides) in the exhaust are reduced. The low frequency component of the signal from circuit 44 passes via low pass filter 62 and half wave rectifier 64 to form a signal, dependent upon engine acceleration, used by circuit 68 to control the opening of valve 90 in dependence upon the acceleration, and by circuit 72 to control the rate of opening of the valve in dependence upon the acceleration and its duration.

Title: Improvements in and relating to the preparation of magnesium oxide-containing material for reduction purposes
IPC: C22B26/22
Filed: 1943-06-16
Abstract: A method of preparing magnesium oxide-containing material for treatment with a predetermined quantity of solid reducing agent, comprises uniformly incorporating the solid reducing-agent with a precipitate resulting from the treatment of convertible magnesium salt-containing brines with reagents capable of effecting the precipitation of magnesium hydroxide therefrom.  Carbon may be used as the precipitant and may be prepared from carbonaceous material capable of forming carbon at a calcining temperature under non-oxidising conditions.  Suitable precipitants are calcium hydroxide and calcined dolomite.  Mixing of reducing agent and magnesium hydroxide is preferably done just prior to the separation of the precipitate from the mother liquor, or from the washing water, should such be used to wash the precipitate.  The mixture is then conditioned for subsequent treatment at a reduction temperature by heating to between 800 DEG  C. and the reduction temperature.  When coal or coke is used as reducing agent the mixing may be performed in a paint-mixing machine, the resultant mixture being then extruded, say from a plodding machine, into cylindrical or other suitable form, and is subjected to a temperature not greater than 800 DEG  C. for removal of the free water, and then to a temperature between 800 DEG C. and 1250 DEG  C. for the removal of combined water and for leaving the mixture in the form of irregular pieces.  Additional reducing-agent, above that amount stoichiometrically satisfying the magnesium salts present in the brine, may be used to compensate for potential losses during calcination.  Calcination is preferably effected under reduced pressure and in a non-oxidising atmosphere.
