Title: Self-propelled vibratory roller
IPC: E01C19/28
Filed: 1970-04-16
Abstract: 1312501 Road rollers U-AMMANN MASCHINENFABRIK AG 16 April 1970 [5 May 1969] 18304/70 Heading B7H A self propelled vibratory roller comprises re leasable clutch means disposed between vibratory and propulsion drives and common drive means for said drives, the clutch means being so arranged that the vibratory drive can be driven simultaneously with the propulsion drive. Each of the rollers (not shown) which are mounted in tandem has a worm gear 3, 4 for the propulsion drive and a bevel gear 5, 6; 7, 8 for the vibration drive. A diesel engine drives a pulley 16 connected to a drive shaft 15 for both propulsion and vibration drives. Two ratio change speed gearing means 21, 22, 23, 24 and a reversing clutch 17, 18 are provided. For forward drive in first gear the clutch 17 is engaged with the gear 21 coupled with the gear 23 (position 23a) and in the forward second gear the gear 23 meshes with gear 24. Both vibrator drives are independent of the change speed gearing. For reverse movement the clutch 18 is engaged with the gears via gear 25 rigidly mounted on shaft 13 and the first and second drive gears are operated in the same way as before. The gear 21 drives the gear 19 and thus the bevel gear 5 of the vibrator drive. The drive shafts 9, 13 are coupled to drive shafts 11, 14 by Cordan joints to permit transmission from the gear case 1 to the gear case 2 even if the two rollers are out of parallel while travelling in a curve. The vibrator drive changes direction with the propulsion drive but the vibrator drive could be made independent of the direction of the propulsion drive. The vibrator drive may be through change speed gearing and/or a releasable clutch.

Title: Improvements in or connected with instruments for automatically recording depth or roll and depth for use in testing torpedoes
IPC: F42B19/01
Filed: 1919-07-24
Abstract: 152,789. Barr & Stroud, Barr, A., and Stroud, W. July 24, 1919. Torpedoes, locomotive, recording depth and roll of.-Consists mainly'in the use of a spring motor for imparting motion to the travelling sheet on which the record of depth or depth and roll is made during a run of the torpedo, an adjustable speed governor being provided. In the apparatus shown in Figs. 1 and 2, a sheet of paper is unwound from a roller G on to a roller G<1> by means of the spring motor, and, while the paper passes over a guide-roller G<2>, it receives a record of depth and a record of rolling by two markers H, J respectively, Fig. 9, the marker H being connected by link-work H<1>, 14, 11 to the rod K<2> of an hydrostatic piston K controlled by a spring L, and the marker J being connected by a rack J<1> and sector N to the pendulum P. To ensure a tension in the paper, the drive from the spring motor is received by the guide-roller G<2> and transmitted through a friction coupling to the receiving-roller G<1> in such a ratio that the peripheral speed of the receiving-roller would be greater than that of the guide-roller, but for the intervention of the friction coupling. The spring motor comprises two spring drums A, B connected in series by their common spindle 1. The springs are wound up by the rotation of the drum A. which is provided with a ratchet clutch to prevent unwinding; and the other drum B transmits motion to the paper rollers through a variablespeed gear E<1> with which is connected a centrifugal governor F provided with a disk F<1> adapted to come in contact with an adjustable brake-shoe to maintain a constant speed. This mechanism is released automatically, at the moment a torpedo is launched, by means of a set-back of a spring-controlled bolt S due to its inertia. The bolt S, in setting back, turns a pivoted catch 17. releasing a rod R, which is moved out by a spring and thereby releases a disk 4 on the spindle of the centrifugal governor. A spring lever 5, Fig. 6, then gives a rotational start to the disk 4, after which it is disengaged from the disk.

Title: Improvements in or relating to photographic reflex cameras
IPC: G03B19/12
Filed: 1958-06-09
Abstract: 840,072. Reflex cameras. KODAK Ltd. June 9, 1958 [June 14, 1957 (2)], No. 18393/58. Class 98(1). In a reflex single-lens camera with a betweenlens shutter, the shutter is arrested in a partly run-down condition corresponding to the initial closed position of the shutter after focusing, said arresting being brought about by a latching device, the latching device being released by a lightobstructing flap after it has moved from its lightsealing position to the position in which it is completely clear of the path of the light rays. Thus an exposure cannot be made until mirror and flap are fully clear. The mechanism shown, as regards winding the film, setting and releasing the shutter, and controlling the viewing mirror 12 and light-obstructing flap 13, is substantially the same as that described and shown in Specification 840,071. In the present arrangement, the further provision is made of a latching lever 85 which co-operates with a pin 84 on a ring gear 63. As described in Specification 840,071 the lug 69 engages in the disc 71 to prevent the shutter initially from running down. When the release member 51 is depressed, the mirror 12 swings up, and strikes lever 70, so disengaging lug 69, which allows the shutter mechanism to run down sufficiently for the shutter to close. As the mirror swings up, it also moves the slide bar 41 which has been retaining the light-obstructing flap 13 in position, so that this also now swings up out of the way. The running down of the shutter mechanism, in which ring gear 63 also participates, has been arrested before completion by a latching device 85, of which a recessed shoulder 89 engages a pin 87 on the ring gear 63. When the flap 13 has swung completely out of the path of the light rays, it strikes a lug 88 of the latch 85, lifting the latter clear of the pin 84, so that the ring gear 63 is now freed to allow complete run down of the shutter mechanism, to operate the shutter blades and make an exposure. The latch and pin arrangement 84, 85 is replaced in Fig. 2 (not shown) by a shouldered disc engaged by a lever, which is similarly released as flap 13 swings upwards. The flap 13 may be combined with the mirror 12, in which case it operates both shutter release catches.

Filed: 1918-11-18
Abstract: 128,834. Broche, L. Nov. 18, 1918. Fixed-chamber appatatus. - Relates to syphondischarged apparatus, and consists in the discharge of an air - compression measuring-chamber during a period wherein a further supply from the reservoir is prevented by causing the liquid in the receptacle to seal the pipe supplying venting air to the reservoir. Liquid flows from the closed reservoir a into a vessel d, compressing air therein, and also into a syphon e. When the syphon is primed, flow takes place into the receptacle f, the necessary air passing to the reservoir by a pipe g leading from the delivery aperture of the siphon. The flow of liquid from the reservoir can be arrested at any desired instant by immersing the end of the delivery pipe in the liquid already discharged, after which the syphon continues to discharge the air-compression vessel d and the delivery comes to an end. Several modifications are described according to which the pipes are arranged somewhat differently but function in the same manner; this applies to the junction of the delivery and reservoir air-supply pipes e and g and to the provision of a pipe from the lower end of the air-compression chamber to the upper part of the reservoir. Regulation of the quantity supplied is effected by raising or lowering the syphon relatively to the air-compression chamber, or by altering the capacity of this chamber. Fig. 14 shows an arrangement in which there is an upward closed extension r of the air-compression chamber, and an indiarubber bulb for cleaning the lower end of the air tube g. According to Fig. 17 a reserve of liquid is contained in a tank s which can be filled by an inlet t provided with a pipe u for conveying air under pressure; a pipe v with a valve b connects the tank with the reservoir a, which is filled when compressed air is admitted to the tank by the pipe u. This form may be provided with a valve r on the air-compression chamber supplypipe c, and the apparatus will function when an air communication g is made at the upper part of the syphon e unless the receiver f is omitted.
