Abstract: 133,458. Lewis, E. H. Oct. 12, 1918. Range-finders. - Range-finders, also adapted for finding heights, comprise a graduated bar A having a sight-carrying cross-piece B sliding upon it and reading against graduations on the bar A giving the ratio of the range to the distance advanced in making the t w o observations necessary with this instrument. One of two sights C, D sliding on the crosspiece B is placed centrally at F and alined from the end O of the bar A upon the range-object, while the other is alined upon an auxiliary object, the cross-piece B 'being pushed up against a stop H; after the observer has advanced a known distance towards the range-object, similar alinements of the sight are obtained by sliding the cross-bar towards O. In finding heights, the two sights, one of which is centrally placed, are set upon the ends of the object and a similar setting obtained, after the observer has advanced a known distance towards the object, by sliding in the cross-piece. The ratio of the height required to the range which is caleulated as before, is given by the position of the lateral sight upon the graduations of the crosspiece.

Title: Improvements in or relating to methods of and apparatus for making graphic recordings on electro-sensitive recording material
IPC: G01S7/60
Filed: 1963-04-04
Abstract: 1,031,841. Echo sounding. ELECTROACUSTIC G.m.b.H. April 4, 1963 [April 4, 1962], No. 13417/63. Heading H4D. In an echo-sounding arrangement including means for producing a graphic recording on current sensitive recording material the echo signals are converted to pulse type signals of length dependent on the strength of the echoes and of constant amplitude, the latter having such a value that the heat produced by the recording current does not cause the recording material to " smoke " or cause strong echoes, such as those from the sea-bed, to " spread " over the recording material and fuse with, and so obscure, weaker echoes, such as those from shoals of fish. The recording thus produced comprises marks of constant blackness the spacings between which vary inversely as the echo strength. The required pulse type signals are derived by modulating a sawtooth wave with the received echo signals and then limiting the " top " and " bottom " excursions of the modulated wave after which a desired degree of amplification is introduced to produce pulses of sufficient strength to give rise to a completely black trace without " spreading " or burning of the recording material.

Title: Improvements in or relating to the application of liquids, such as paint, by means of a brush
IPC: B44D3/22
Filed: 1947-05-20
Abstract: 628,297. Reservoir brush. BETTS & CO., Ltd., and HOLMES, G. E. May 20, 1947, No. 13503. [Class 19] [Also in Group XXVIII] Apparatus for supplying a predetermined amount of liquid, e.g. paint, to a brush comprises a cylinder 4, a piston made in two parts, one consisting of a cylindrical plug 7 having a central aperture for the reception of a stem 8 and a thin skirt 9, and a second part consisting of a plug 10 having an aperture for the stem 8 and adapted to fit inside the skirt 9 so as to leave a cavity 11 between the plugs. The piston divides the cylinder into a front compartment which communicates with the brush and a rear compartment, the latter being in communication with the cavity 11 through openings 12 in the plug 10. The stem 8 is given a limited axial play in the piston by providing a collar 13 (Fig. 1) on the stem or by providing two collars 13A and 13B (Fig. 4) on the stem on either side of the piston. An axial passage 14 in the stem leads to a port 15 adjacent the cavity 11 and another passage 16 leads from a second port 17 to the rear end of the stem 8 which is screwed into a header 18 for communication with a supply of liquid by means of a flexible pipe 19 (Fig. 6). A spring 20 normally holds the piston in its retracted position (Figs. 3 and 5-not shown) when the stem 8 is moved forwardly to the position shown in Figs. 1 and 4 the liquid is drawn into the rear compartment of the cylinder 4 while the liquid in the front compartment is forced into the brush since the piston moves with the stem when the collar 13 or 13B abuts against the piston. When the stem is moved in the reverse direction the port 17 is closed by the plug 10 thus cutting off the supply of liquid from the source and the liquid in the rear compartment passes to the front compartment through the port 15. The stem may be held stationary once the cylinder reciprocated. Thus in Fig. 6 the cylinder 4 is held in a bracket 21 mounted on a block 23 secured to a rod 25 slidable in two arms 26, 27 of a frame 28. The rear end of the rod 25 is held in a block 30 and the rod 25 is reciprocated by reciprocation of a rod 31 pivoted by links to the block 30 and to the lower end of the arm 26 and the extent of the forward movement of the cylinder is determined by adjusting a threaded pin 34 which projects into a socket 35 in the frame 28 and the stroke of the piston in the cylinder is adjusted by means of a screw 36 carried in the arm 27. A number of holes 38 are provided so that the frame may be mounted in proper position with respect to a rotating chuck 39 upon which the articles to which liquid is to be applied are mounted.

[Class 20(i)] A glasshouse comprises a framework of rods on which are fixed brackets by which the sheets of glass, &c., which form the roof and walls are removably supported, the lower portions of the wall sheets resting in recesses between projections on the brackets and some or all of the brackets at the top of the sheets being provided with holders for retaining the sheets in a closed or more or less open position. End frame members are composed of uprights A bent to form sloping roof members A<3> to which are attached other uprights A<1> joined to the uprights A by transverse members A2. Intermediate frame members consist of uprights F bent to form roof members Fl and having attached angled rods F<2> which support a shelf G. Hooked tie rods between opposite rods A<1> and between opposite rods F<2> may be used as gauges in the erection of the frames and may be left in position as struts after erection. Tie rods may also be formed with cranked ends to drop into holes in the brackets. Bottom brackets B have holes for fixing to a foundation K or pegging to the ground and suitable projections for locating the lower edges of the glass sheets. Intermediate brackets C, Fig. 8, have projections c<2>, c<4> for holding the spring clips J, projections c<1>, c<3> for holding the lower edges of the sheets above, and have their edges bent over to form flanges which are bent to embrace the straps. Two additional straps may join the tubes at each side of the ladder. The treads are formed with an embossed pattern to prevent the feet slipping. Each of the upper ends of the tube forming the stay 10 is fixed in a bracket 13 pivoted at 17 to the rear tube of the corresponding side frame. The edge 16a of each bracket is shaped to engage round its rear tube, to prevent the stay from opening too far. The ladder may narrow slightly from top to bottom. In a modification, the stay 10 is combined with holes c<6> for the cranked ends of tie rods. Top brackets D, Fig. 1, have similar projections for holding the springs J and incorporate strips of metal which may be bent over the lower edges of roof sheets to hold them in position. Alternatively these sheets may be held by spring clips embracing the uprights above the brackets D. Ridge brackets E have projections for holding the upper edges of the roof sheets and holes for fixing them together or to a support such as the beam M. As shown in Fig. 8 the brackets are welded to the uprights, but in a modification they are clamped on with set screws and the springs J are held by a nut and washer on the set screw. Using half the framework shown in Fig. 1 a glasshouse may be constructed as a lean-to.

Title: Article Storage Unit
Inventor: JONES HAROLD JOHN CYRIL
IPC: B65G47/51
Filed: 1967-03-23
Abstract: 1,152,769. Endless conveyers. GALLAHER Ltd. 20 March, 1968 [23 March, 1967], No. 13675/67. Heading B8A. An article storage unit for fitting to a conveyer 7 which carries a succession of similar articles 8 from one station A to another B, the unit comprising a magazine which is arranged to be mounted at the side of and below the conveyer 7 and to support a stack of the articles 8 on a moving platform 9 which can be raised and lowered in the magazine. First transfer means 13 are provided for moving one or more articles 8 on the conveyer 7 from the conveyer on to the top of the stack in the magazine, there being second transfer means 13a for transferring one or more articles 8 on the top of the stack laterally on to the conveyer 7. The unit also comprises a control system which is responsive to a first signal S1 and thereupon causes the first transfer means 13 continually to transfer articles on to the top of the stack in the magazine and the magazine platform 9 continually to be lowered so that the height of the stack is lowered to receive further articles 8. The control system is also responsive to a second signal S4 to cause the second transfer means 13a to transfer articles 8 continually from the top of the stack on to the conveyer and the magazine platform 9 continually to raise the stack so that as the articles 8 at the top of the stack are transferred on to the conveyer 7 the articles 8 beneath are raised for subsequent transfer to the conveyer 7. The invention is described as applied to the supply of cigarette packages from a packeting machine (Fig. 6) to a wrapping maching. Operation.-The platform 9 is raised and/or lowered by the action of lead screws 10, 10, driven in respective directions when one or other of field brake clutches 43, are energized by switches S4 or S1 as the case may be. Switch S1 is closed when the wrapping machine ceases to be operational and the switch S4 is closed when no packet is present at this point on the conveyer 7. A feeler 30 rests on the surface of the top packet 8 of the stack on the platform 9 and is adapted to operate switches S5A and S5B for a small movement respectively down or up of the top packet. These switches also control respectively the clutches 43. Then when a packet is pushed'from the stack on to the conveyer, the platform is caused by closing of the switch S5A to rise until the top of the stack operates the switch S5B. This movement corresponds to the thickness of one packet. The transfer means comprise pushers 13, 13a operated by a cam 27 driven through gearing from the same motor 32 as drives the clutches 43. Cam followers 26, 26a, which transmit the cam motion respectively to the pushers 13, 13a are normally held from bearing on the cam by the action of solenoid controlled latches 24, 24a. These are controlled by re-closing of the switch S5A.

Title: Improvements in and relating to the manufacture of cementitious compositions
IPC: C04B7/12
Filed: 1932-05-13
Abstract: A cementitious composition is produced by the admixture of finely ground pumice and quicklime.  The type of pumice used is preferably trachytic pumice.  1-5 per cent of natural rock asphalt is also preferably added to prevent the formation of blow holes when the composition is used as a plaster.  When the material is to be used as a plaster for inside work calcined gypsum or anhydrite is added, and when it is to be used as a plaster for outside work, ordinary cement is added.  When slabs, blocks or boards are to be made, a fibrous binder such as asbestos is added in amounts of about 10 per cent.  In an example 60 per cent of pumice is mixed with 40 per cent of lime.
Patent GB-138913-A (GB)
Abstract: 138,913. Bosch Akt.-Ges., R. March 9, 1918, [Convention date]. Rotary distributors; centrifugal switches. - The rotary part of a distributor is provided with both a sparking contact i spaced apart from its cooperating fixed contacts, and a spring plunger rubbing contact b engaging the fixed contacts g and withdrawn therefrom at normal high speeds. The fixed sparking contacts h are extensions of the main fixed contacts g, and the movable sparking contact is on an extension of a socket d, in which the carrier c for the plunger contact is mounted and pressed outwardly by a spring e. The centre of gravity of the carrier is inwards of the axis of rotation so that, while at low starting speeds, the rubbing contact serves as an alternative to the spark gap, at normal high speeds the rubbing contact is withdrawn from the fixed contacts by centrifugal action, and the distribution takes place across the spark gap, thereby avoiding the troubles which may arise from a rubbing contact.
