A mortise bolt for doors intended to be used in an emergency comprises a casing 10 a bolt member 24 mounted on a bolt carrier 14 resilient means e.g. springs 22, 23 urging the bolt carrier towards a door releasing position and a frangible body 28 holding the bolt carrier in the door bolting position so that upon breaking the body the bolt carrier is moved to its door releasing position, the arrangement being such that access can be had to the frangible body from both sides of the casing. In the construction shown the bolt carrier is formed with a shelf 32 upon which the forward edge of the frangible body 28, which as shown, is a plate of glass, rests. The rearward edge portion of the plate of glass rests upon an upstanding flange 31 of the casing and lips 30 prevent movement of the plate longitudinally away from the bolt carrier. A cover plate for the casing is provided with protrusions which maintain the plate 28 in the required position, both the cover plate and the casing having apertures through which access to the plate 28 is obtainable so that it can be broken. The bolt carrier is guided in its movement by bars 20 and 21 which project rearwardly from a front plate 11 of the casing and these guide bars are surrounded by the springs 22 and 23 which are under compression when the plate 28 is in position so that when it is broken the springs urge the bolt carrier rearwardly and move the bolt member 24 to the door releasing position. The bolt member 24 is attached to the bolt carrier by means of a stem 25 slidable in a slot 26 in the carrier, a coil spring 29 being located around the stem 25 and acting between the rear face of the bolt member and the front face of the carrier 14, this construction enabling the bolt to be retracted by closing the door after the plate 28 has been fitted. Instead of the plate 28 being made of glass it can be made of earthenware and can carry an instructive or identifying legend. The extension 17 is provided with a protrusion which extends to the side of the casing to form a shelf on which the plate 28 may be located if desired. A shelf is also formed at the opening through the casing so that the frangible body may be located on the shelves. When the shelves 32, 33 are used a frame for the hole in the door by which the frangible body is reached is provided to prevent the inadvertent or unauthorized removal of the body. Reference has been directed by the Comptroller to Specification 943,249.

Title: Improvements in and relating to magnetic amplifier circuits
IPC: H02P9/32
Filed: 1950-05-09
Abstract: 688,395. Magnetic amplifiers. BRITISH THOMSON-HOUSTON CO., Ltd. May 9, 1950 [May 20, 1949], No. 11522/50. Class 40 (iv). In a magnetic amplifier in which the current to load 10 supplied from A.C. source 7, 8 through windings 3 and 4 in series is controlled by the flux through a control winding 5, compensation for changes of voltage and/ or frequency of the A.C. source is effected by a winding 6, the terminals of which are short-circuited by a rectifier 19 to produce a flux in opposition to that of the control winding. The fluxes in the centre core due to windings 3, 4 are unbalanced by the flux from the control winding 5 so that alternating current (mainly harmonics) proportional to the load current is induced in winding 6. With the control flux from winding 5 constant changes of load current due to mains variations are compensated by changes in the flux from winding 6. A modification in which additional compensation is effected by supplying current to winding 6 from the A.C. source through a phase-shifting network is described with reference to Fig. 1 (not shown). Other modifications, not shown, include amplifiers having two separate cores and also a 4-limbed core. In the case of the latter the windings 5 and 6 are wound around both of the two inner cores.

Title: Improvements in the handling of bottles and crates in bottle washing machines
IPC: B08B9/42
Filed: 1927-05-07
Abstract: 290,037. Enock, A. G. May 7, 1927. Bottles, washing.-A machine for washing bottles in their crates without the necessity of first inverting them by hand comprises a device for inverting a standard crate of bottles, a " tunnel " washing machine through which the bottles travel mouth downwards, and a reinverter at the delivery end. The crates D of dirty bottles are fed one at a time on a roller conveyer D<1> by an intermittentlydriven band D<3> beneath a casing F which delivers on to each crate a grid E designed to prevent the bottles falling out when inverted. The crate then enters a rotary inverter B operated by hand or mechanically to invert the crate with the grid upon it, and thence passes over the wash troughs A on rollers a<2>, being urged forward by succeeding crates. Finally it is reinverted by a similar inverter B<1> and delivered by a conveyer D<2>, the grids being removed by hooks on a conveyer band F<1> and returned to the casing F. In modifications, the separate grids are dispensed with and the bottles are retained in their crates over the wash troughs A by travelling grids in the form of transverse rods and chains or links, or of pivoted framegrids, and flat-sided sprockets. Dead plates from the inverter guide the bottles on to the grids. In another modification, a fixed longitudinal grid is arranged above the rollers a<2>. In an automatic arrangement, Fig. 14, for rotating the inverter by the pressure of the oncoming crate, the inverter is driven by a toothed rim h<2>, pinions h<1>, h, and a rack bar H. The pinion h is normally held from engagement with the rack H by a spring, but is forced into engagement by a bellcrank lever h<3> and push rod h<4> adapted to be engaged by the advancing crate. In a modification of this arrangement, the forward section of the conveyer D<1> is pivoted and linked to the lever h<3> so that the weight of the advancing crate forces the pinion h into engagement with the rack H. A spring stop may be used to hold the inverter in upright or inverted position. A cooling device may be provided at the delivery end of the reinverter B<1>.

Abstract: 869,818. Fishing rods. RODRILL CO. Ltd. March 24, 1960 [April 13, 1959], No. 12422/59. Class 48. A device for securing the footplate of a reel to the cork or rubber handle of a fishing rod comprises a metal or plastic sleeve C having two metal or plastic locating rings C<SP>1</SP>, C<SP>2</SP>, at least one of which is slidable along the sleeve C, and a metal, or plastic clamping-ring D slidable on the sleeve C and having an internal circumferential groove D<SP>1</SP> of varying depth into which projects a roller E or ball disposed in a longitudinal external groove C<SP>5</SP> in the sleeve C. In the embodiment shown the locating-ring C<SP>1</SP> is fixed to the sleeve C and the other sleeve C<SP>2</SP> is slidable thereon. The ends of the reel footplate are engaged under lips C<SP>3</SP>, C<SP>4</SP> on the locating rings C<SP>1</SP>, C<SP>2</SP> and the clamping ring D is clamped to the sleeve C in abutment with the slidable locating ring C<SP>2</SP> by rotating the ring D so that the roller E becomes wedged in one of the shallow end portions of the internal groove D<SP>1</SP>. If both locating rings are slidable either a stop formed by deforming the sleeve behind one of the locating rings or two clamping rings are provided and the longitudinal groove C<SP>5</SP> extends along the whole length of the sleeve. One of the slidable locating rings may be keyed against rotation on the sleeve. The longitudinal groove C<SP>5</SP> may extend at a small angle to the axis of the sleeve so that the rotational movement of the clamping ring D produces a small axial movement thereof to tighten the engagement of the locating rings on the footplate. The clamping of the footplate to the sleeve may also cause the sleeve to be pressed tightly against the cork handle. In a modification the sleeve C has a slot allowing the footplate to seat on the cork handle and the sleeve is slidable thereon. The longitudinal external groove C<SP>5</SP> is formed, as by stamping, to constitute an internal rib which co-operates with a longitudinal groove in the cork handle to prevent rotation of the sleeve. In a further modification the ball or roller is carried in an axial internal groove in the clamping-ring and co-operates with a groove of variable depth around the sleeve.
