Locks, attaching; night latches and like spring locks; latches, sliding.-A door latch comprises a latch unit A and a latch actuating unit B, the latter being provided with means extending through an anchor plate 10 secured to the latch unit so as to form an interlock therewith when the two units are assembled in a door C. The latch unit consists of a plate 2 to which is secured a back plate 41 which receives a flange 40 on the latch housing 4, so that the housing may be swivelled in relation to the plate to adapt the latch for both right and left hand doors. The housing guides the bolt 5 which is withdrawn against a spring 7 by a bar 6 which has a swivel connection with the bolt. An anchor plate 10 is secured to the end plates 8, 9, of the housing 4 and a roll-back crank 12 pivoted to the latchbar at 11 fits over the anchor plate. These parts are permanently secured together so that they may be inserted in a hole in the door and secured by screws. A transverse hole D is then bored through the door to receive the latch actuating unit which comprises a flattened bar 15 passing through a slot in the roll-back crank and rotated either by key mechanism or by a knob or handle, or, as illustrated, by both. The key mechanism consists of a pin tumbler lock operated by a key K and having a cylinder 17 and escutcheon plate 18. The cylinder plug carries a cam plate 19 coacting with a driver plate 20 carried by the bar 15, the cam plate having a projection 19<a> co-operating with shoulders 20<a>, 20<b> on the driver plate. Thus when the latch is actuated by the key mechanism, the cam projection 19<a> is rotated to engage one of the shoulders on the driver to rotate the spindle 15 and withdraw the latch. The latch may also be withdrawn from a knob 16 carried on the spindle which may rotate between the limits of the shoulders 20<a>, 20<b> and the cam projection 19<a> without interfering with the key mechanism. In order to provide for doors of different thicknesses and to ensure correct positioning of the latch, the two units may be interlocked by means of posts 30, 31 carried by the cylinder 17 and passing respectively through a hole 30<a> and slot 31<a> in the anchor plate. These bolts are tapped and are engaged by screws 33 passing through the escutcheon plate 35.

IPC: D01F4/00
Filed: 1930-12-23
Abstract: Silk fibroin is dissolved in liquid anhydrous ammonia at a temperature below the boiling point of ammonia, preferably at -77 DEG C.  The solution may be mixed with water at the same time removing the ammonia, for example by raising the temperature or by passing gases through the solution, whereupon a slightly yellow aqueous solution of fibroin is obtained of any desired concentration, for p example aqueous solutions of 35 per cent fibroin content or more may be obtained.  When adding the solution in ammonia to water, it is an advantage to spray the solution through a nozzle in a state of fine division and to allow the spray to fall through a considerable layer of air before it arrives at the surface of the water.  The silk fibroin to be dissolved is freed from impurities by suitable means and is preferably subjected to a preliminary treatment with a feebly acid or feebly alkaline solution, or both.  The aqueous fibroin solution obtained may be spun into simple salt baths to produce artificial yarn.

[Also in Groups XXVIII and XXXII] An electrically driven compressor has a freely oscillating armature and piston assembly mounted within the compressor housing by resilient elements spaced portions of which make solid contact with each other when the piston has reached the position of maximum stroke and so limit the travel of the piston. U- shaped laminations 4 contain a coil 5 connected in series with a rectifier to a single-phase mains to be acted upon by a half-wave train which causes it to be magnetised periodically. Laminations 7 forming magnetic yokes have a recess accommodating the armature 9. The armature is rigidly connected to the piston 8 inside which are springs 15, 16 resting on a collar 18 on a bolt 17 secured to a flexible plate 20. When current is supplied to coil 5 the armature 9 is attracted and the piston makes a compression stroke (see Group XXVIII). The characteristics of the springs being such that they have a braking effect which increases at an increasing rate before the piston reaches the end of its travel. The suction stroke is effected by the springs and these provide the only forces acting in the intervals between the half-cycles of the magnetising current. Other arrangements of springs than that shown in Fig. 1 may be employed and various forms of spring are described (see Group XXXII). Specification 848,889 is referred to.
